2. Cleo is diagnosed with osteoporosis. Which electrolytes are involved in the development of this disorder?

Calcium and sodium

Calcium and phosphorous

Phosphorous and potassium

Potassium and sodium

In osteoporosis, bones lose calcium and phosphate salts, becoming porous, brittle, and abnormally vulnerable to fracture. Sodium and potassium aren't involved in the development of osteoporosis.

3. The nurse is ware that the most relevant knowledge about oxygen administration to a male client with COPD is

Oxygen at 1-2L/min is given to maintain the hypoxic stimulus for breathing.

Hypoxia stimulates the central chemoreceptors in the medulla that makes the client breath.

Oxygen is administered best using a non-rebreathing mask

Blood gases are monitored using a pulse oximeter.

COPD causes a chronic CO2 retention that renders the medulla insensitive to the CO2 stimulation for breathing. The hypoxic state of the client then becomes the stimulus for breathing. Giving the client oxygen in low concentrations will maintain the client’s hypoxic drive.

4. Wilfredo with a recent history of rectal bleeding is being prepared for a colonoscopy. How should the nurse Patricia position the client for this test initially?

Lying on the right side with legs straight

Lying on the left side with knees bent

Prone with the torso elevated

Bent over with hands touching the floor

For a colonoscopy, the nurse initially should position the client on the left side with knees bent. Placing the client on the right side with legs straight, prone with the torso elevated, or bent over with hands touching the floor wouldn't allow proper visualization of the large intestine.

Explanation

For a colonoscopy, the nurse initially should position the client on the left side with knees bent. Placing the client on the right side with legs straight, prone with the torso elevated, or bent over with hands touching the floor wouldn't allow proper visualization of the large intestine.

5. Situation: Stacy is diagnosed with acute lymphoid leukemia (ALL) and beginning chemotherapy.

Stacy’s mother states to the nurse that it is hard to see Stacy with no hair. The best response for the nurse is:

“Stacy looks very nice wearing a hat”.

“You should not worry about her hair, just be glad that she is alive”.

“This is only temporary; Stacy will re-grow new hair in 3-6 months, but may be different in texture”.

This is the appropriate response. The nurse should help the mother how to cope with her own feelings regarding the child’s disease so as not to affect the child negatively. When the hair grows back, it is still of the same color and texture.

Explanation

6. A 62-year-old male client was in a motor vehicle accident as an unrestrained driver. He’s now in the emergency department complaining of difficulty of breathing and chest pain. On auscultation of his lung field, no breath sounds are present in the upper lobe. This client may have which of the following conditions?

Bronchitis

Pneumonia

Pneumothorax

Tuberculosis (TB)

From the trauma the client experienced, it’s unlikely he has bronchitis, pneumonia, or TB; rhonchi with bronchitis, bronchial breath sounds with TB would be heard.

Explanation

From the trauma the client experienced, it’s unlikely he has bronchitis, pneumonia, or TB; rhonchi with bronchitis, bronchial breath sounds with TB would be heard.

7. Norma, with recent colostomy expresses concern about the inability to control the passage of gas. Nurse Oliver should suggest that the client plan to:

Eliminate foods high in cellulose.

Decrease fluid intake at meal times.

Avoid foods that in the past caused flatus.

Adhere to a bland diet prior to social events.

Foods that bothered a person preoperatively will continue to do so after a colostomy.

Explanation

Foods that bothered a person preoperatively will continue to do so after a colostomy.

8. Herbert, a 45 year old construction engineer is brought to the hospital unconscious after falling from a 2-story building. When assessing the client, the nurse would be most concerned if the assessment revealed:

Reactive pupils

A depressed fontanel

Bleeding from ears

An elevated temperature

The nurse needs to perform a thorough assessment that could indicate alterations in cerebral function, increased intracranial pressures, fractures and bleeding. Bleeding from the ears occurs only with basal skull fractures that can easily contribute to increased intracranial pressure and brain herniation.

Explanation

The nurse needs to perform a thorough assessment that could indicate alterations in cerebral function, increased intracranial pressures, fractures and bleeding. Bleeding from the ears occurs only with basal skull fractures that can easily contribute to increased intracranial pressure and brain herniation.

9. Mr. Mendoza who has suffered a cerebrovascular accident (CVA) is too weak to move on his own. To help the client avoid pressure ulcers, Nurse Celia should:

Turn him frequently.

Perform passive range-of-motion (ROM) exercises.

Reduce the client's fluid intake.

Encourage the client to use a footboard.

The most important intervention to prevent pressure ulcers is frequent position changes, which relieve pressure on the skin and underlying tissues. If pressure isn't relieved, capillaries become occluded, reducing circulation and oxygenation of the tissues and resulting in cell death and ulcer formation. During passive ROM exercises, the nurse moves each joint through its range of movement, which improves joint mobility and circulation to the affected area but doesn't prevent pressure ulcers. Adequate hydration is necessary to maintain healthy skin and ensure tissue repair. A footboard prevents plantar flexion and footdrop by maintaining the foot in a dorsiflexed position.

10. Mario comes to the clinic complaining of fever, drenching night sweats, and unexplained weight loss over the past 3 months. Physical examination reveals a single enlarged supraclavicular lymph node. Which of the following is the most probable diagnosis?

Influenza

Sickle cell anemia

Leukemia

Hodgkin’s disease

Hodgkin’s disease typically causes fever night sweats, weight loss, and lymph mode enlargement. Influenza doesn’t last for months. Clients with sickle cell anemia manifest signs and symptoms of chronic anemia with pallor of the mucous membrane, fatigue, and decreased tolerance for exercise; they don’t show fever, night sweats, weight loss or lymph node enlargement. Leukemia doesn’t cause lymph node enlargement.

11. Situation: Stacy is diagnosed with acute lymphoid leukemia (ALL) and beginning chemotherapy.

Stacy is discharged from the hospital following her chemotherapy treatments. Which statement of Stacy’s mother indicated that she understands when she will contact the physician?

“I should contact the physician if Stacy has difficulty in sleeping”.

“I will call my doctor if Stacy has persistent vomiting and diarrhea”.

“My physician should be called if Stacy is irritable and unhappy”.

“Should Stacy have continued hair loss, I need to call the doctor”.

Persistent (more than 24 hours) vomiting, anorexia, and diarrhea are signs of toxicity and the patient should stop the medication and notify the health care provider. The other manifestations are expected side effects of chemotherapy.

Explanation

Persistent (more than 24 hours) vomiting, anorexia, and diarrhea are signs of toxicity and the patient should stop the medication and notify the health care provider. The other manifestations are expected side effects of chemotherapy.

12. Nurse Rose is aware that the statement that best explains why furosemide (Lasix) is administered to treat hypertension is:

It dilates peripheral blood vessels.

It decreases sympathetic cardioacceleration.

It inhibits the angiotensin-coverting enzymes

It inhibits reabsorption of sodium and water in the loop of Henle.

Furosemide is a loop diuretic that inhibits sodium and water reabsorption in the loop Henle, thereby causing a decrease in blood pressure. Vasodilators cause dilation of peripheral blood vessels, directly relaxing vascular smooth muscle and decreasing blood pressure. Adrenergic blockers decrease sympathetic cardioacceleration and decrease blood pressure. Angiotensin-converting enzyme inhibitors decrease blood pressure due to their action on angiotensin.

13. Rico with diabetes mellitus must learn how to self-administer insulin. The physician has prescribed 10 U of U-100 regular insulin and 35 U of U-100 isophane insulin suspension (NPH) to be taken before breakfast. When teaching the client how to select and rotate insulin injection sites, the nurse should provide which instruction?

"Inject insulin into healthy tissue with large blood vessels and nerves."

"Rotate injection sites within the same anatomic region, not among different regions."

"Administer insulin into areas of scar tissue or hypotrophy whenever possible."

"Administer insulin into sites above muscles that you plan to exercise heavily later that day."

The nurse should instruct the client to rotate injection sites within the same anatomic region. Rotating sites among different regions may cause excessive day-to-day variations in the blood glucose level; also, insulin absorption differs from one region to the next. Insulin should be injected only into healthy tissue lacking large blood vessels, nerves, or scar tissue or other deviations. Injecting insulin into areas of hypertrophy may delay absorption. The client shouldn't inject insulin into areas of lipodystrophy (such as hypertrophy or atrophy); to prevent lipodystrophy, the client should rotate injection sites systematically. Exercise speeds drug absorption, so the client shouldn't inject insulin into sites above muscles that will be exercised heavily.

14. Ricardo is scheduled for a prostatectomy, and the anesthesiologist plans to use a spinal (subarachnoid) block during surgery. In the operating room, the nurse positions the client according to the anesthesiologist's instructions. Why does the client require special positioning for this type of anesthesia?

To prevent confusion

To prevent seizures

To prevent cerebrospinal fluid (CSF) leakage

To prevent cardiac arrhythmias

The client receiving a subarachnoid block requires special positioning to prevent CSF leakage and headache and to ensure proper anesthetic distribution. Proper positioning doesn't help prevent confusion, seizures, or cardiac arrhythmias.

Explanation

The client receiving a subarachnoid block requires special positioning to prevent CSF leakage and headache and to ensure proper anesthetic distribution. Proper positioning doesn't help prevent confusion, seizures, or cardiac arrhythmias.

15. The term “pink puffer” refers to the female client with which of the following conditions?

Adult respiratory distress syndrome (ARDS)

Asthma

Chronic obstructive bronchitis

Emphysema

Because of the large amount of energy it takes to breathe, clients with emphysema are usually cachectic. They’re pink and usually breathe through pursed lips, hence the term “puffer.” Clients with ARDS are usually acutely short of breath. Clients with asthma don’t have any particular characteristics, and clients with chronic obstructive bronchitis are bloated and cyanotic in appearance.

16. Situation: Stacy is diagnosed with acute lymphoid leukemia (ALL) and beginning chemotherapy.

During the administration of chemotherapy agents, Nurse Oliver observed that the IV site is red and swollen, when the IV is touched Stacy shouts in pain. The first nursing action to take is:

Notify the physician

Flush the IV line with saline solution

Immediately discontinue the infusion

Apply an ice pack to the site, followed by warm compress.

Edema or swelling at the IV site is a sign that the needle has been dislodged and the IV solution is leaking into the tissues causing the edema. The patient feels pain as the nerves are irritated by pressure and the IV solution. The first action of the nurse would be to discontinue the infusion right away to prevent further edema and other complication.

17. Jestoni with chronic renal failure (CRF) is admitted to the urology unit. The nurse is aware that the diagnostic test are consistent with CRF if the result is:

Increased pH with decreased hydrogen ions.

Increased serum levels of potassium, magnesium, and calcium.

Blood urea nitrogen (BUN) 100 mg/dl and serum creatinine 6.5 mg/ dl.

Uric acid analysis 3.5 mg/dl and phenolsulfonphthalein (PSP) excretion 75%.

The normal BUN level ranges 8 to 23 mg/dl; the normal serum creatinine level ranges from 0.7 to 1.5 mg/dl. The test results of the answer are abnormally elevated, reflecting CRF and the kidneys' decreased ability to remove nonprotein nitrogen waste from the blood. CRF causes decreased pH and increased hydrogen ions — not vice versa. CRF also increases serum levels of potassium, magnesium, and phosphorous, and decreases serum levels of calcium. A uric acid analysis of 3.5 mg/dl falls within the normal range of 2.7 to 7.7 mg/dl; PSP excretion of 75% also falls with the normal range of 60% to 75%.

18. Situation: Mr. Gonzales was admitted to the hospital with ascites and jaundice. To rule out cirrhosis of the liver:

The biopsy of Mr. Gonzales confirms the diagnosis of cirrhosis. Mr. Gonzales is at increased risk for excessive bleeding primarily because of:

Impaired clotting mechanism

Varix formation

Inadequate nutrition

Trauma of invasive procedure

Cirrhosis of the liver results in decreased Vitamin K absorption and formation of clotting factors resulting in impaired clotting mechanism.

Explanation

Cirrhosis of the liver results in decreased Vitamin K absorption and formation of clotting factors resulting in impaired clotting mechanism.

19. Nurse Michelle calculates the IV flow rate for a postoperative client. The client receives 3,000 ml of Ringer’s lactate solution IV to run over 24 hours. The IV infusion set has a drop factor of 10 drops per milliliter. The nurse should regulate the client’s IV to deliver how many drops per minute?

3000 x 10 divided by 24 x 60.

20. Situation: Mr. Gonzales was admitted to the hospital with ascites and jaundice. To rule out cirrhosis of the liver:

Mr. Gonzales develops hepatic encephalopathy. Which clinical manifestation is most common with this condition?

Increased urine output

Altered level of consciousness

Decreased tendon reflex

Hypotension

Changes in behavior and level of consciousness are the first sins of hepatic encephalopathy. Hepatic encephalopathy is caused by liver failure and develops when the liver is unable to convert protein metabolic product ammonia to urea. This results in accumulation of ammonia and other toxic in the blood that damages the cells.

1.2 ml

2.4 ml

3.5 ml

4.2 ml

.05 mg/ 1 ml = .12mg/ x ml, .05x = .12, x = 2.4 ml.

Explanation

.05 mg/ 1 ml = .12mg/ x ml, .05x = .12, x = 2.4 ml.

22. Tracy is receiving combination chemotherapy for treatment of metastatic carcinoma. Nurse Ruby should monitor the client for the systemic side effect of:

Ascites

Nystagmus

Leukopenia

Polycythemia

Leukopenia, a reduction in WBCs, is a systemic effect of chemotherapy as a result of myelosuppression.

Explanation

Leukopenia, a reduction in WBCs, is a systemic effect of chemotherapy as a result of myelosuppression.

23. Patrick is in the oliguric phase of acute tubular necrosis and is experiencing fluid and electrolyte imbalances. The client is somewhat confused and complains of nausea and muscle weakness. As part of the prescribed therapy to correct this electrolyte imbalance, the nurse would expect to:

Administer Kayexalate

Restrict foods high in protein

Increase oral intake of cheese and milk.

Administer large amounts of normal saline via I.V.

Kayexalate,a potassium exchange resin, permits sodium to be exchanged for potassium in the intestine, reducing the serum potassium level.

Explanation

Kayexalate,a potassium exchange resin, permits sodium to be exchanged for potassium in the intestine, reducing the serum potassium level.

24. Nurse Sherry is teaching male client regarding his permanent artificial pacemaker. Which information given by the nurse shows her knowledge deficit about the artificial cardiac pacemaker?

Take the pulse rate once a day, in the morning upon awakening

May be allowed to use electrical appliances

Have regular follow up care

May engage in contact sports

The client should be advised by the nurse to avoid contact sports. This will prevent trauma to the area of the pacemaker generator.

Explanation

25. The term “blue bloater” refers to a male client which of the following conditions?

Adult respiratory distress syndrome (ARDS)

Asthma

Chronic obstructive bronchitis

Emphysema

Clients with chronic obstructive bronchitis appear bloated; they have large barrel chest and peripheral edema, cyanotic nail beds, and at times, circumoral cyanosis. Clients with ARDS are acutely short of breath and frequently need intubation for mechanical ventilation and large amount of oxygen. Clients with asthma don’t exhibit characteristics of chronic disease, and clients with emphysema appear pink and cachectic.

26. A female client arrives at the emergency department with chest and stomach pain and a report of black tarry stool for several months. Which of the following order should the nurse Oliver anticipate?

Cardiac monitor, oxygen, creatine kinase and lactate dehydrogenase levels

Prothrombin time, partial thromboplastin time, fibrinogen and fibrin split product values.

Electrocardiogram, complete blood count, testing for occult blood, comprehensive serum metabolic panel.

Electroencephalogram, alkaline phosphatase and aspartate aminotransferase levels, basic serum metabolic panel

An electrocardiogram evaluates the complaints of chest pain, laboratory tests determines anemia, and the stool test for occult blood determines blood in the stool. Cardiac monitoring, oxygen, and creatine kinase and lactate dehydrogenase levels are appropriate for a cardiac primary problem. A basic metabolic panel and alkaline phosphatase and aspartate aminotransferase levels assess liver function. Prothrombin time, partial thromboplastin time, fibrinogen and fibrin split products are measured to verify bleeding dyscrasias, An electroencephalogram evaluates brain electrical activity.

27. After undergoing a cardiac catheterization, Tracy has a large puddle of blood under his buttocks. Which of the following steps should the nurse take first?

Call for help.

Obtain vital signs

Ask the client to “lift up”

Apply gloves and assess the groin site

Observing standard precautions is the first priority when dealing with any blood fluid. Assessment of the groin site is the second priority. This establishes where the blood is coming from and determineshow much blood has been lost. The goal in this situation is to stop the bleeding. The nurse would call for help if it were warranted after the assessment of the situation. After determining the extent of the bleeding, vital signs assessment is important. The nurse should never move the client, in case a clot has formed. Moving can disturb the clot and cause rebleeding.

29. Nurse Ron begins to teach a male client how to perform colostomy irrigations. The nurse would evaluate that the instructions were understood when the client states, “I should:

Lie on my left side while instilling the irrigating solution.”

Keep the irrigating container less than 18 inches above the stoma.”

Instill a minimum of 1200 ml of irrigating solution to stimulate evacuation of the bowel.”

Insert the irrigating catheter deeper into the stoma if cramping occurs during the procedure.”

This height permits the solution to flow slowly with little force so that excessive peristalsis is not immediately precipitated.

Explanation

This height permits the solution to flow slowly with little force so that excessive peristalsis is not immediately precipitated.

30. Tonny has undergoes a left thoracotomy and a partial pneumonectomy. Chest tubes are inserted, and one-bottle water-seal drainage is instituted in the operating room. In the postanesthesia care unit Tonny is placed in Fowler's position on either his right side or on his back. The nurse is aware that this position:

Reduce incisional pain.

Facilitate ventilation of the left lung.

Equalize pressure in the pleural space.

Increase venous return

Since only a partial pneumonectomy is done, there is a need to promote expansion of this remaining Left lung by positioning the client on the opposite unoperated side.

Explanation

Since only a partial pneumonectomy is done, there is a need to promote expansion of this remaining Left lung by positioning the client on the opposite unoperated side.

31. Situation: Mr. Gonzales was admitted to the hospital with ascites and jaundice. To rule out cirrhosis of the liver:

Which laboratory test indicates liver cirrhosis?

Decreased red blood cell count

Decreased serum acid phosphate level

Elevated white blood cell count

Elevated serum aminotransferase

Hepatic cell death causes release of liver enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) into the circulation. Liver cirrhosis is a chronic and irreversible disease of the liver characterized by generalized inflammation and fibrosis of the liver tissues.

32. Mario has burn injury. After Forty48 hours, the physician orders for Mario 2 liters of IV fluid to be administered q12 h. The drop factor of the tubing is 10 gtt/ml. The nurse should set the flow to provide:

18 gtt/min

28 gtt/min

32 gtt/min

36 gtt/min

This is the correct flow rate; multiply the amount to be infused (2000 ml) by the drop factor (10) and divide the result by the amount of time in minutes (12 hours x 60 minutes)

Explanation

This is the correct flow rate; multiply the amount to be infused (2000 ml) by the drop factor (10) and divide the result by the amount of time in minutes (12 hours x 60 minutes)

33. Timothy’s arterial blood gas (ABG) results are as follows; pH 7.16; Paco2 80 mm Hg; Pao2 46 mm Hg; HCO3- 24mEq/L; Sao2 81%. This ABG result represents which of the following conditions?

Metabolic acidosis

Metabolic alkalosis

Respiratory acidosis

Respiratory alkalosis

Because Paco2 is high at 80 mm Hg and the metabolic measure, HCO3- is normal, the client has respiratory acidosis. The pH is less than 7.35, academic, which eliminates metabolic and respiratory alkalosis as possibilities. If the HCO3- was below 22 mEq/L the client would have metabolic acidosis.

Explanation

36. The nurse is aware that the following terms used to describe reduced cardiac output and perfusion impairment due to ineffective pumping of the heart is:

Anaphylactic shock

Cardiogenic shock

Distributive shock

Myocardial infarction (MI)

Cardiogenic shock is shock related to ineffective pumping of the heart. Anaphylactic shock results from an allergic reaction. Distributive shock results from changes in the intravascular volume distribution and is usually associated with increased cardiac output. MI isn’t a shock state, though a severe MI can lead to shock.

Distributive shock results from changes in the intravascular volume distribution and is usually associated with increased cardiac output. MI isn’t a shock state, though a severe MI can lead to shock.

37. Ms. X has just been diagnosed with condylomata acuminata (genital warts). What information is appropriate to tell this client?

This condition puts her at a higher risk for cervical cancer; therefore, she should have a Papanicolaou (Pap) smear annually.

The most common treatment is metronidazole (Flagyl), which should eradicate the problem within 7 to 10 days.

The human papillomavirus (HPV), which causes condylomata acuminata, can't be transmitted during oral sex.

Women with condylomata acuminata are at risk for cancer of the cervix and vulva. Yearly Pap smears are very important for early detection. Because condylomata acuminata is a virus, there is no permanent cure. Because condylomata acuminata can occur on the vulva, a condom won't protect sexual partners. HPV can be transmitted to other parts of the body, such as the mouth, oropharynx, and larynx.

38. The nurse is aware that the following symptoms is most commonly an early indication of stage 1 Hodgkin’s disease?

Pericarditis

Night sweat

Splenomegaly

Persistent hypothermia

In stage 1, symptoms include a single enlarged lymph node (usually), unexplained fever, night sweats, malaise, and generalized pruritis. Although splenomegaly may be present in some clients, night sweats are generally more prevalent. Pericarditis isn’t associated with Hodgkin’s disease, nor is hypothermia. Moreover, splenomegaly and pericarditis aren’t symptoms. Persistent hypothermia is associated with Hodgkin’s but isn’t an early sign of the disease.

A spontaneous pneumothorax occurs when the client’s lung collapses, causing an acute decreased in the amount of functional lung used in oxygenation. The sudden collapse was the cause of his chest pain and shortness of breath. An asthma attack would show wheezing breath sounds, and bronchitis would have rhonchi. Pneumonia would have bronchial breath sounds over the area of consolidation.

40. After a motor vehicle accident, Armand an 22-year-old client is admitted with a pneumothorax. The surgeon inserts a chest tube and attaches it to a chest drainage system. Bubbling soon appears in the water seal chamber. Which of the following is the most likely cause of the bubbling?

Air leak

Adequate suction

Inadequate suction

Kinked chest tube

Bubbling in the water seal chamber of a chest drainage system stems from an air leak. In pneumothorax an air leak can occur as air is pulled from the pleural space. Bubbling doesn’t normally occur with either adequate or inadequate suction or any preexisting bubbling in the water seal chamber.

41. Nurse Ron is assessing a client admitted with second- and third-degree burns on the face, arms, and chest. Which finding indicates a potential problem?

Partial pressure of arterial oxygen (PaO2) value of 80 mm Hg.

Urine output of 20 ml/hour.

White pulmonary secretions.

Rectal temperature of 100.6° F (38° C).

A urine output of less than 40 ml/hour in a client with burns indicates a fluid volume deficit. This client's PaO2 value falls within the normal range (80 to 100 mm Hg). White pulmonary secretions also are normal. The client's rectal temperature isn't significantly elevated and probably results from the fluid volume deficit.

42. A 67-year-old client develops acute shortness of breath and progressive hypoxia requiring right femur. The hypoxia was probably caused by which of the following conditions?

Asthma attack

Atelectasis

Bronchitis

Fat embolism

Long bone fractures are correlated with fat emboli, whichcause shortness of breath and hypoxia. It’s unlikely the client has developed asthma or bronchitis without a previous history. He could develop atelectasis but it typically doesn’t produce progressive hypoxia.

43. If a client requires a pneumonectomy, what fills the area of the thoracic cavity?

The space remains filled with air only

The surgeon fills the space with a gel

Serous fluids fills the space and consolidates the region

The tissue from the other lung grows over to the other side

Serous fluid fills the space and eventually consolidates, preventing extensive mediastinal shift of the heart and remaining lung. Air can’t be left in the space. There’s no gel that can be placed in the pleural space. The tissue from the other lung can’t cross the mediastinum, although a temporary mediastinal shift exits until the space is filled.

“I will wear the stockings until the physician tells me to remove them.”

“I should wear the stockings even when I am sleep.”

“Every four hours I should remove the stockings for a half hour.”

“I should put on the stockings before getting out of bed in the morning.”

Promote venous return by applying external pressure on veins.

Explanation

Promote venous return by applying external pressure on veins.

45. Nurse Kate is aware that one of the following classes of medication protect the ischemic myocardium by blocking catecholamines and sympathetic nerve stimulation is:

Beta -adrenergic blockers

Calcium channel blocker

Narcotics

Nitrates

Beta-adrenergic blockers work by blocking beta receptors in the myocardium, reducing the response to catecholamines and sympathetic nerve stimulation. They protect the myocardium, helping to reduce the risk of another infraction by decreasing myocardial oxygen demand. Calcium channel blockers reduce the workload of the heart by
decreasing the heart rate. Narcotics reduce myocardial oxygen demand, promote vasodilation, and decrease anxiety. Nitrates reduce myocardial oxygen consumption bt decreasing left ventricular end diastolic pressure (preload) and systemic vascular resistance (afterload).

46. Katrina has an abnormal result on a Papanicolaou test. After admitting that she read her chart while the nurse was out of the room, Katrina asks what dysplasia means. Which definition should the nurse provide?

Presence of completely undifferentiated tumor cells that don't resemble cells of the tissues of their origin.

Increase in the number of normal cells in a normal arrangement in a tissue or an organ.

Replacement of one type of fully differentiated cell by another in tissues where the second type normally isn't found.

Alteration in the size, shape, and organization of differentiated cells.

Dysplasia refers to an alteration in the size, shape, and organization of differentiated cells. The presence of completely undifferentiated tumor cells that don't resemble cells of the tissues of their origin is called anaplasia. An increase in the number of normal cells in a normal arrangement in a tissue or an organ is called hyperplasia. Replacement of one type of fully differentiated cell by another in tissues where the second type normally isn't found is called metaplasia.

48. For a client with Graves' disease, which nursing intervention promotes comfort?

Restricting intake of oral fluids

Placing extra blankets on the client's bed

Limiting intake of high-carbohydrate foods

Maintaining room temperature in the low-normal range

Graves' disease causes signs and symptoms of hypermetabolism, such as heat intolerance, diaphoresis, excessive thirst and appetite, and weight loss. To reduce heat intolerance and diaphoresis, the nurse should keep the client's room temperature in the low-normal range. To replace fluids lost via diaphoresis, the nurse should encourage, not restrict, intake of oral fluids. Placing extra blankets on the bed of a client with heat intolerance would cause discomfort. To provide needed energy and calories, the nurse should encourage the client to eat high-carbohydrate foods.

49. Matilda, with hyperthyroidism is to receive Lugol’s iodine solution before a subtotal thyroidectomy is performed. The nurse is aware that this medication is given to:

Decrease the total basal metabolic rate.

Maintain the function of the parathyroid glands.

Block the formation of thyroxine by the thyroid gland.

Decrease the size and vascularity of the thyroid gland.

Lugol’s solution provides iodine, which aids in decreasing the vascularity of the thyroid gland, which limits the risk of hemorrhage when surgery is performed.

50. Which of the following treatment is a suitable surgical intervention for a client with unstable angina?

Cardiac catheterization

Echocardiogram

Nitroglycerin

Percutaneous transluminal coronary angioplasty (PTCA)

PTCA can alleviate the blockage and restore blood flow and oxygenation. An echocardiogram is a noninvasive diagnosis test. Nitroglycerin is an oral sublingual medication. Cardiac catheterization is a diagnostic tool – not a treatment.

51. A client with hypertension ask the nurse which factors can cause blood pressure to drop to normal levels?

Kidneys’ excretion to sodium only.

Kidneys’ retention of sodium and water

Kidneys’ excretion of sodium and water

Kidneys’ retention of sodium and excretion of water

The kidneys respond to rise in blood pressure by excreting sodium and excess water. This response ultimately affects sysmolic blood pressure by regulating blood volume. Sodium or water retention would only further increase blood pressure. Sodium and water travel together across the membrane in the kidneys; one can’t travel without the other.

52. Ruby is receiving thyroid replacement therapy develops the flu and forgets to take her thyroid replacement medicine. The nurse understands that skipping this medication will put the client at risk for developing which of the following lifethreatening complications?

Exophthalmos

Thyroid storm

Myxedema coma

Tibial myxedema

Myxedema coma, severe hypothyroidism, is a life-threatening condition that may develop if thyroid replacement medication isn't taken. Exophthalmos, protrusion of the eyeballs, is seen with hyperthyroidism. Thyroid storm is life-threatening but is caused by severe hyperthyroidism. Tibial myxedema, peripheral mucinous edema involving the lower leg, is associated with hypothyroidism but isn't life-threatening.

53. Nurse Sugar is assessing a client with Cushing's syndrome. Which observation should the nurse report to the physician immediately?

Pitting edema of the legs

An irregular apical pulse

Dry mucous membranes

Frequent urination

Because Cushing's syndrome causes aldosterone overproduction, which increases urinary potassium loss, the disorder may lead to hypokalemia. Therefore, the nurse should immediately report signs and symptoms of hypokalemia, such as an irregular apical pulse, to the physician. Edema is an expected finding because aldosterone overproduction causes sodium and fluid retention. Dry mucous membranes and frequent urination signal dehydration, which isn't associated with Cushing's syndrome.

54. Anthony suffers burns on the legs, which nursing intervention helps prevent contractures?

Applying knee splints

Elevating the foot of the bed

Hyperextending the client's palms

Performing shoulder range-of-motion exercises

Applying knee splints prevents leg contractures by holding the joints in a position of function. Elevating the foot of the bed can't prevent contractures because this action doesn't hold the joints in a position of function. Hyperextending a body part for an extended time is inappropriate because it can cause contractures. Performing shoulder range-of-motion exercises can prevent contractures in the shoulders, but not in the legs.

56. When prioritizing care, which of the following clients should the nurse Olivia assess first?

A 17-year-old clients 24-hours postappendectomy

A 33-year-old client with a recent diagnosis of Guillain-Barre syndrome

A 50-year-old client 3 days postmyocardial infarction

A 50-year-old client with diverticulitis

Guillain-Barre syndrome is characterized by ascending paralysis and potential respiratory failure. The order of client assessment should follow client priorities, with disorder of airways, breathing, and then circulation. There’s no information to suggest the postmyocardial infarction client has an arrhythmia or other complication. There’s no evidence to suggest hemorrhage or perforation for the remaining clients as a priority of care.

57. Maritess was recently diagnosed with a genitourinary problem and is being examined in the emergency department. When palpating the her kidneys, the nurse should keep which anatomical fact in mind?

The left kidney usually is slightly higher than the right one.

The kidneys are situated just above the adrenal glands.

The average kidney is approximately 5 cm (2") long and 2 to 3 cm (¾" to 1-1/8") wide.

The kidneys lie between the 10th and 12th thoracic vertebrae.

The left kidney usually is slightly higher than the right one. An adrenal gland lies atop each kidney. The average kidney measures approximately 11 cm (4-3/8") long, 5 to 5.8 cm (2" to 2¼") wide, and 2.5 cm (1") thick. The kidneys are located retroperitoneally, in the posterior aspect of the abdomen, on either side of the vertebral column. They lie between the 12th thoracic and 3rd lumbar vertebrae.

58. A male client has jugular distention. On what position should the nurse place the head of the bed to obtain the most accurate reading of jugular vein distention?

High Fowler’s

Raised 10 degrees

Raised 30 degrees

Supine position

Jugular venous pressure is measured with a centimeter ruler to obtain the vertical distance between the sternal angle and the point of highest pulsation with the head of the bed inclined between 15 to 30 degrees. Increased pressure can’t be seen when the client is supine or when the head of the bed is raised 10 degrees because the point that marks the pressure level is above the jaw (therefore, not visible). In high Fowler’s position, the veins would be barely discernible above the clavicle.

60. Norma has started a new drug for hypertension. Thirty minutes after she takes the drug, she develops chest tightness and becomes short of breath and tachypneic. She has a decreased level of consciousness. These signs indicate which of the following conditions?

Asthma attack

Pulmonary embolism

Respiratory failure

Rheumatoid arthritis

The client was reacting to the drug with respiratory signs of impending anaphylaxis, which could lead to eventually respiratory failure. Although the signs are also related to an asthma attack or a pulmonary embolism, consider the new drug first. Rheumatoid arthritis doesn’t manifest these signs.

61. A male client had a nephrectomy 2 days ago and is now complaining of abdominal pressure and nausea. The first nursing action should be to:

Auscultate bowel sounds.

Palpate the abdomen.

Change the client's position.

Insert a rectal tube.

If abdominal distention is accompanied by nausea, the nurse must first auscultate bowel sounds. If bowel sounds are absent, the nurse should suspect gastric or small intestine dilation and these findings must be reported to the physician. Palpation should be avoided postoperatively with abdominal distention. If peristalsis is absent, changing positions and inserting a rectal tube won't relieve the client's discomfort.

62. Nurse Lourdes is teaching a client recovering from addisonian crisis about the need to take fludrocortisone acetate and hydrocortisone at home. Which statement by the client indicates an understanding of the instructions?

"I'll take my hydrocortisone in the late afternoon, before dinner."

"I'll take all of my hydrocortisone in the morning, right after I wake up."

"I'll take two-thirds of the dose when I wake up and one-third in the late afternoon."

"I'll take the entire dose at bedtime."

Hydrocortisone, a glucocorticoid, should be administered according to a schedule that closely reflects the body's own secretion of this hormone; therefore, two-thirds of the dose of hydrocortisone should be taken in the morning and one-third in the late afternoon. This dosage schedule reduces adverse effects.

63. A male client arriving in the emergency department is receiving cardiopulmonary resuscitation from paramedics who are giving ventilations through an endotracheal (ET) tube that they placed in the client’s home. During a pause in compressions, the cardiac monitor shows narrow QRS complexes and a heart rate of beats/minute with a palpable pulse. Which of the following actions should the nurse take first?

Start an L.V. line and administer amiodarone (Cardarone), 300 mg L.V. over 10 minutes.

Check endotracheal tube placement.

Obtain an arterial blood gas (ABG) sample.

Administer atropine, 1 mg L.V.

ET tube placement should be confirmed as soon as the client arrives in the emergency department. Once the airways is secured, oxygenation and ventilation should be confirmed using an end-tidal carbon dioxide monitor and pulse oximetry. Next, the nurse should make sure L.V. access is established. If the client experiences symptomatic bradycardia, atropine is administered as ordered 0.5 to 1 mg every 3 to 5 minutes to a total of 3 mg. Then the nurse should try to find the cause of the client’s arrest by obtaining an ABG sample. Amiodarone is indicated for ventricular tachycardia, ventricular fibrillation and atrial flutter – not symptomatic bradycardia.

64. Nurse Tristan is caring for a male client in acute renal failure. The nurse should expect hypertonic glucose, insulin infusions, and sodium bicarbonate to be used to treat:

Hypernatremia.

Hypokalemia.

Hyperkalemia.

Hypercalcemia.

Hyperkalemia is a common complication of acute renal failure. It's life-threatening if immediate action isn't taken to reverse it. The administration of glucose and regular insulin, with sodium bicarbonate if necessary, can temporarily prevent cardiac arrest by moving potassium into the cells and temporarily reducing serum potassium levels. Hypernatremia, hypokalemia, and hypercalcemia don't usually occur with acute renal failure and aren't treated with glucose, insulin, or sodium bicarbonate.

66. Nurse Nikki knows that laboratory results supports the diagnosis of systemic lupus erythematosus (SLE) is:

Elavated serum complement level

Thrombocytosis, elevated sedimentation rate

Pancytopenia, elevated antinuclear antibody (ANA) titer

Leukocysis, elevated blood urea nitrogen (BUN) and creatinine levels

Laboratory findings for clients with SLE usually show pancytopenia, elevated ANA titer, and decreased serum complement levels. Clients may have elevated BUN and creatinine levels from nephritis, but the increase does not indicate SLE.

68. A male client with inflammatory bowel disease undergoes an ileostomy. On the first day after surgery, Nurse Oliver notes that the client's stoma appears dusky. How should the nurse interpret this finding?

Blood supply to the stoma has been interrupted.

This is a normal finding 1 day after surgery.

The ostomy bag should be adjusted.

An intestinal obstruction has occurred.

An ileostomy stoma forms as the ileum is brought through the abdominal wall to the surface skin, creating an artificial opening for waste elimination. The stoma should appear cherry red, indicating adequate arterial perfusion. A dusky stoma suggests decreased perfusion, which may result from interruption of the stoma's blood supply and may lead to tissue damage or necrosis. A dusky stoma isn't a normal finding. Adjusting the ostomy bag wouldn't affect stoma color, which depends on blood supply to the area. An intestinal obstruction also wouldn't change stoma color.

69. The nurse is aware that one of the following classes of medications maximizes cardiac performance in clients with heart failure by increasing ventricular contractility?

Beta-adrenergic blockers

Calcium channel blocker

Diuretics

Inotropic agents

Inotropic agents are administered to increase the force of the heart’s contractions, thereby increasing ventricular contractility and ultimately increasing cardiac output. Beta-adrenergic blockers and calcium channel blockers decrease the heart rate and ultimately decreased the workload of the heart. Diuretics are administered to decrease the overall vascular volume, also decreasing the workload of the heart.

70. A male client with a gunshot wound requires an emergency blood transfusion. His blood type is AB negative. Which blood type would be the safest for him to receive?

AB Rh-positive

A Rh-positive

A Rh-negative

O Rh-positive

Human blood can sometimes contain an inherited D antigen. Persons with the D antigen have Rh-positive blood type; those lacking the antigen have Rh-negative blood. It’s important that a person with Rhnegative blood receives Rh-negative blood. If Rh-positive blood is administered to an Rh-negative person, the recipient develops anti-Rh agglutinins, and sub sequent transfusions with Rh-positive blood may cause serious reactions with clumping and hemolysis of red blood cells.

71. Hemoptysis may be present in the client with a pulmonary embolism because of which of the following reasons?

Alveolar damage in the infracted area

Involvement of major blood vessels in the occluded area

Loss of lung parenchyma

Loss of lung tissue

The infracted area produces alveolar damage that can lead to the production of bloody sputum, sometimes in massive amounts. Clot formation usually occurs in the legs. There’s a loss of lung parenchyma and subsequent scar tissue formation.

72. Kristine is scheduled for a bronchoscopy. When teaching Kristine what to expect afterward, the nurse's highest priority of information would be:

Food and fluids will be withheld for at least 2 hours.

Warm saline gargles will be done q 2h.

Coughing and deep-breathing exercises will be done q2h.

Only ice chips and cold liquids will be allowed initially.

Prior to bronchoscopy, the doctors sprays the back of the throat with anesthetic to minimize the gag reflex and thus facilitate the insertion of the bronchoscope. Giving the client food and drink after the procedure without checking on the return of the gag reflex can cause the client to aspirate. The gag reflex usually returns after two hours.

73. Capillary glucose monitoring is being performed every 4 hours for a client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which he receives 8 U of regular insulin. Nurse Mariner should expect the dose's:

Onset to be at 2 p.m. and its peak to be at 3 p.m.

Onset to be at 2:15 p.m. and its peak to be at 3 p.m.

Onset to be at 2:30 p.m. and its peak to be at 4 p.m.

Onset to be at 4 p.m. and its peak to be at 6 p.m.

Regular insulin, which is a short-acting insulin, has an onset of 15 to 30 minutes and a peak of 2 to 4 hours. Because the nurse gave the insulin at 2 p.m., the expected onset would be from 2:15 p.m. to 2:30 p.m. and the peak from 4 p.m. to 6 p.m.

75. Which of the following laboratory test results would suggest to the nurse Len that a client has a corticotropin-secreting pituitary adenoma?

High corticotropin and low cortisol levels

Low corticotropin and high cortisol levels

High corticotropin and high cortisol levels

Low corticotropin and low cortisol levels

A corticotropin-secreting pituitary tumor would cause high corticotropin and high cortisol levels. A high corticotropin level with a low cortisol level and a low corticotropin level with a low cortisol level would be associated with hypocortisolism. Low corticotropin and high cortisol levels would be seen if there was a primary defect in the adrenal glands.

76. The nurse knows that neurologic complications of multiple myeloma (MM) usually involve which of the following body system?

Brain

Muscle spasm

Renal dysfunction

Myocardial irritability

Back pain or paresthesia in the lower extremities may indicate impending spinal cord compression from a spinal tumor. This should be recognized and treated promptly as progression of the tumor may result in paraplegia. The other options, which reflect parts of the nervous system, aren’t usually affected by MM.

77. Arnold, a 19-year-old client with a mild concussion is discharged from the emergency department. Before discharge, he complains of a headache. When offered acetaminophen, his mother tells the nurse the headache is severe and she would like her son to have something stronger. Which of the following responses by the nurse is appropriate?

“Your son had a mild concussion, acetaminophen is strong enough.”

“Aspirin is avoided because of the danger of Reye’s syndrome in children or young adults.”

“Narcotics are avoided after a head injury because they may hide a worsening condition.”

Stronger medications may lead to vomiting, which increases the intracarnial pressure (ICP).”

Narcotics may mask changes in the level of consciousness that indicate increased ICP and shouldn’t acetaminophen is strong enough ignores the mother’s question and therefore isn’t appropriate. Aspirin is contraindicated in conditions that may have bleeding, such as trauma, and for children or young adults with viral illnesses due to the danger of Reye’s syndrome. Stronger medications may not necessarily lead to vomiting but will sedate the client, thereby masking changes in his level of consciousness.

79. Nurse Maria plans to administer dexamethasone cream to a female client who has dermatitis over the anterior chest. How should the nurse apply this topical agent?

With a circular motion, to enhance absorption.

With an upward motion, to increase blood supply to the affected area

In long, even, outward, and downward strokes in the direction of hair growth

In long, even, outward, and upward strokes in the direction opposite hair growth

When applying a topical agent, the nurse should begin at the midline and use long, even, outward, and downward strokes in the direction of hair growth. This application pattern reduces the risk of follicle irritation and skin inflammation.

80. Situation: Mr. Gonzales was admitted to the hospital with ascites and jaundice. To rule out cirrhosis of the liver:

When Mr. Gonzales regained consciousness, the physician orders 50 ml of Lactose p.o. every 2 hours. Mr. Gozales develops diarrhea. The nurse best action would be:

“I’ll see if your physician is in the hospital”.

“Maybe your reacting to the drug; I will withhold the next dose”.

“I’ll lower the dosage as ordered so the drug causes only 2 to 4 stools a day”.

“Frequently, bowel movements are needed to reduce sodium level”.

Lactulose is given to a patients with hepatic encephalopathy to reduce absorption of ammonia in the intestines by binding with ammonia and promoting more frequent bowel movements. If the patient experience diarrhea, it indicates over dosage and the nurse must reduce the amount of medication given to the patient. The stool will be mashy or soft. Lactulose is also very sweet and may cause cramping and bloating.

81. Which of the following groups of symptoms indicates a ruptured abdominal aortic aneurysm?

Lower back pain, increased blood pressure, decreased re blood cell (RBC) count, increased white blood (WBC) count.

Severe lower back pain, decreased blood pressure, decreased RBC count, increased WBC count.

Severe lower back pain, decreased blood pressure, decreased RBC count, decreased RBC count, decreased WBC count.

Intermitted lower back pain, decreased blood pressure, decreased RBC count, increased WBC count.

Severe lower back pain indicates an aneurysm rupture, secondary to pressure being applied within the abdominal cavity. When ruptured occurs, the pain is constant because it can’t be alleviated until the aneurysm is repaired. Blood pressure decreases due to the loss of blood. After the aneurysm ruptures, the vasculature is interrupted and blood volume is lost, so blood pressure wouldn’t increase. For the same reason, the RBC count is decreased – not increased. The WBC count increases as cell migrate to the site of injury.

82. A 37-year-old male client was admitted to the coronary care unit (CCU) 2 days ago with an acute myocardial infarction. Which of the following actions would breach the client confidentiality?

The CCU nurse notifies the on-call physician about a change in the client’s condition

The emergency department nurse calls up the latest electrocardiogram results to check the client’s progress.

At the client’s request, the CCU nurse updates the client’s wife on his condition

The emergency department nurse is no longer directly involved with the client’s care and thus has no legal right to information about his present condition. Anyone directly involved in his care (such as the telemetry nurse and the on-call physician) has the right to information about his condition. Because the client requested that the nurse update his wife on his condition, doing so doesn’t breach confidentiality.

83. A male client is scheduled for a transsphenoidal hypophysectomy to remove a pituitary tumor. Preoperatively, the nurse should assess for potential complications by doing which of the following?

Testing for ketones in the urine

Testing urine specific gravity

Checking temperature every 4 hours

Performing capillary glucose testing every 4 hours

The nurse should perform capillary glucose testing every 4 hours because excess cortisol may cause insulin resistance, placing the client at risk for hyperglycemia. Urine ketone testing isn't indicated because the client does secrete insulin and, therefore, isn't at risk for ketosis. Urine specific gravity isn't indicated because although fluid balance can be compromised, it usually isn't dangerously imbalanced. Temperature regulation may be affected by excess cortisol and isn't an accurate indicator of infection.

84. Francis with leukemia has neutropenia. Which of the following functions must frequently assessed?

Blood pressure

Bowel sounds

Heart sounds

Breath sounds

Pneumonia, both viral and fungal, is a common cause of death in clients with neutropenia, so frequent assessment of respiratory rate and breath sounds is required. Although assessing blood pressure, bowel sounds, and heart sounds is important, it won’t help detect pneumonia.

86. Instructions for a client with systemic lupus erythematosus (SLE) would include information about which of the following blood dyscrasias?

Dressler’s syndrome

Polycythemia

Essential thrombocytopenia

Von Willebrand’s disease

Essential thrombocytopenia is linked to immunologic disorders, such as SLE and human immunodeficiency vitus. The disorder known as von Willebrand’s disease is a type of hemophilia and isn’t linked to SLE. Moderate to severe anemia is associated with SLE, not polycythermia. Dressler’s syndrome is pericarditis that occurs after a myocardial infarction and isn’t linked to SLE.

87. When evaluating an arterial blood gas from a male client with a subdural hematoma, the nurse notes the Paco2 is 30 mm Hg. Which of the following responses best describes the result?

Appropriate; lowering carbon dioxide (CO2) reduces intracranial pressure (ICP)

Emergent; the client is poorly oxygenated

Normal

Significant; the client has alveolar hypoventilation

A normal Paco2 value is 35 to 45 mm Hg CO2 has vasodilating properties; therefore, lowering Paco2 through hyperventilation will lower ICP caused by dilated cerebral vessels. Oxygenation is evaluated through Pao2 and oxygen saturation. Alveolar hypoventilation would be reflected in an increased Paco2.

88. A 66-year-old client has been complaining of sleeping more, increased urination, anorexia, weakness, irritability, depression, and bone pain that interferes with her going outdoors. Based on these assessment findings, the nurse would suspect which of the following disorders?

Diabetes mellitus

Diabetes insipidus

Hypoparathyroidism

Hyperparathyroidism

Hyperparathyroidism is most common in older women and is characterized by bone pain and weakness from excess parathyroid hormone (PTH). Clients also exhibit hypercaliuria-causing polyuria. While clients with diabetes mellitus and diabetes insipidus also have polyuria, they don't have bone pain and increased sleeping. Hypoparathyroidism is characterized by urinary frequency rather than polyuria.

Fiber intake of 25 to 30 g daily

Less than 30% of calories form fat

Cholesterol intake of less than 300 mg daily

Less than 10% of calories from saturated fat

A client with low serum HDL and high serum LDL levels should get less than 30% of daily calories from fat. The other modifications are appropriate for this client.

90. Macario had coronary artery bypass graft (CABG) surgery 3 days ago. Which of the following conditions is suspected by the nurse when a decrease in platelet count from 230,000 ul to 5,000 ul is noted?

Pancytopenia

Idiopathic thrombocytopemic purpura (ITP)

Disseminated intravascular coagulation (DIC)

Heparin-associated thrombosis and thrombocytopenia (HATT)

HATT may occur after CABG surgery due to heparin use during surgery. Although DIC and ITP cause platelet aggregation and bleeding, neither is common in a client after revascularization surgery. Pancytopenia is a reduction in all blood cells.

Explanation

HATT may occur after CABG surgery due to heparin use during surgery. Although DIC and ITP cause platelet aggregation and bleeding, neither is common in a client after revascularization surgery. Pancytopenia is a reduction in all blood cells.

91. Aldo with a massive pulmonary embolism will have an arterial blood gas analysis performed to determine the extent of hypoxia. The acid-base disorder that may be present is?

Metabolic acidosis

Metabolic alkalosis

Respiratory acidosis

Respiratory alkalosis

A client with massive pulmonary embolism will have a large region and blow off large amount of carbon dioxide, which crosses the unaffected alveolar-capillary membrane more readily than does oxygen and results in respiratory alkalosis.

92. Ricardo, was diagnosed with type I diabetes. The nurse is aware that acute hypoglycemia also can develop in the client who is diagnosed with:

Liver disease

Hypertension

Type 2 diabetes

Hyperthyroidism

The client with liver disease has a decreased ability to metabolize carbohydrates because of a decreased ability to form glycogen (glycogenesis) and to form glucose from glycogen.

Explanation

The client with liver disease has a decreased ability to metabolize carbohydrates because of a decreased ability to form glycogen (glycogenesis) and to form glucose from glycogen.

93. An 18-year-old male client admitted with heat stroke begins to show signs of disseminated intravascular coagulation (DIC). Which of the following laboratory findings is most consistent with DIC?

Low platelet count

Elevated fibrinogen levels

Low levels of fibrin degradation products

Reduced prothrombin time

In DIC, platelets and clotting factors are consumed, resulting in microthrombi and excessive bleeding. As clots form, fibrinogen levels decrease and the prothrombin time increases. Fibrin degeneration products increase as fibrinolysis takes places.

94. Jomari is diagnosed with hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is stabilized and prepared for discharge. When preparing the client for discharge and home management, which of the following statements indicates that the client understands her condition and how to control it?

"If I experience trembling, weakness, and headache, I should drink a glass of soda that contains sugar."

"I will have to monitor my blood glucose level closely and notify the physician if it's constantly elevated."

"If I begin to feel especially hungry and thirsty, I'll eat a snack high in carbohydrates."

Inadequate fluid intake during hyperglycemic episodes often leads to HHNS. By recognizing the signs of hyperglycemia (polyuria, polydipsia, and polyphagia) and increasing fluid intake, the client may prevent HHNS. Drinking a glass of nondiet soda would be appropriate for hypoglycemia. A client whose diabetes is controlled with oral antidiabetic agents usually doesn't need to monitor blood glucose levels. A highcarbohydrate diet would exacerbate the client's condition, particularly if fluid intake is low.

95. Situation: Stacy is diagnosed with acute lymphoid leukemia (ALL) and beginning chemotherapy.
Stacy has beginning stomatitis. To promote oral hygiene and comfort, the nurse in-charge should:

Provide frequent mouthwash with normal saline.

Apply viscous Lidocaine to oral ulcers as needed.

Use lemon glycerine swabs every 2 hours.

Rinse mouth with Hydrogen Peroxide.

Stomatitis can cause pain and this can be relieved by applying topical anesthetics such as lidocaine before mouth care. When the patient is already comfortable, the nurse can proceed with providing the patient with oral rinses of saline solution mixed with equal part of water or hydrogen peroxide mixed water in 1:3 concentrations to promote oral hygiene. Every 2-4 hours.

96. Cyrill with severe head trauma sustained in a car accident is admitted to the intensive care unit. Thirty-six hours later, the client's urine output suddenly rises above 200 ml/hour, leading the nurse to suspect diabetes insipidus. Which laboratory findings support the nurse's suspicion of diabetes insipidus?

Above-normal urine and serum osmolality levels

Below-normal urine and serum osmolality levels

Above-normal urine osmolality level, below-normal serum osmolality level

Below-normal urine osmolality level, above-normal serum osmolality level

In diabetes insipidus, excessive polyuria causes dilute urine, resulting in a below-normal urine osmolality level. At the same time, polyuria depletes the body of water, causing dehydration that leads to an above-normal serum osmolality level. For the same reasons, diabetes insipidus doesn't cause above-normal urine osmolality or below-normal serum osmolality levels.

98. The physician orders laboratory tests to confirm hyperthyroidism in a female client with classic signs and symptoms of this disorder. Which test result would confirm the diagnosis?

No increase in the thyroid-stimulating hormone (TSH) level after 30 minutes during the TSH stimulation test

A decreased TSH level

An increase in the TSH level after 30 minutes during the TSH stimulation test

Below-normal levels of serum triiodothyronine (T3) and serum thyroxine (T4) as detected by radioimmunoassay

In the TSH test, failure of the TSH level to rise after 30 minutes confirms hyperthyroidism. A decreased TSH level indicates a pituitary deficiency of this hormone. Below-normal levels of T3 and T4, as detected by radioimmunoassay, signal hypothyroidism. A below-normal T4 level also occurs in malnutrition and liver disease and may result from administration of phenytoin and certain other drugs.

99. Which of the following drugs would be ordered by the physician to improve the platelet count in a male client with idiopathic thrombocytopenic purpura (ITP)?

Acetylsalicylic acid (ASA)

Corticosteroids

Methotrezate

Vitamin K

Corticosteroid therapy can decrease antibody production and phagocytosis of the antibody-coated platelets, retaining more functioning platelets. Methotrexate can cause thrombocytopenia. Vitamin K is used to treat an excessive anticoagulate state from warfarin overload, and ASA decreases platelet aggregation.

100. Nurse Sarah expects to note an elevated serum glucose level in a client with hyperosmolar hyperglycemic nonketotic syndrome (HHNS). Which other laboratory finding should the nurse anticipate?

Elevated serum acetone level

Serum ketone bodies

Serum alkalosis

Below-normal serum potassium level

A client with HHNS has an overall body deficit of potassium resulting from diuresis, which occurs secondary to the hyperosmolar, hyperglycemic state caused by the relative insulin deficiency. An elevated serum acetone level and serum ketone bodies are characteristic of diabetic ketoacidosis. Metabolic acidosis, not serum alkalosis, may occur in HHNS.
