A patient is admitted to the hospital with a calcium level of 6.0 mg/dL. Which of the following symptoms would you NOT expect to see in this patient?
-
Numbness in hands and feet.
-
Muscle cramping.
-
Hypoactive bowel sounds.
-
Positive Chvostek’s sign.
Correct Answer
A. Hypoactive bowel sounds.Explanation
Normal serum calcium is 8.5 – 10 mg/dL. The patient is hypocalcemic. Increased gastric motility. resulting in hyperactive (not hypoactive) bowel sounds. abdominal cramping and diarrhea is an indication of hypocalcemia. Numbness in hands and feet and muscle cramps are also signs of hypocalcemia. Positive Chvostek’s sign refers to the sustained twitching of facial muscles following tapping in the area of the cheekbone and is a hallmark of hypocalcemia.Rate this question:

A nurse cares for a patient who has a nasogastric tube attached to low suction because of a suspected bowel obstruction. Which of the following arterial blood gas results might be expected in this patient?
-
PH 7.52. PCO2 54 mmHg.
-
PH 7.42. PCO2 40 mmHg.
-
PH 7.25. PCO2 25 mmHg.
-
PH 7.38. PCO2 36 mmHg.
Correct Answer
A. pH 7.52. PCO2 54 mmHg.Explanation
A patient on nasogastric suction is at risk of metabolic alkalosis as a result of loss of hydrochloric acid in gastric fluid. Of the answers given. only answer A (pH 7.52. PCO2 54 mm Hg) represents alkalosis. Answer B is a normal blood gas. Answer C represents respiratory acidosis. Answer D is borderline normal with slightly low PCO2.Rate this question:

A patient is admitted to the hospital for routine elective surgery. Included in the list of current medications is Coumadin (warfarin) at a high dose. Concerned about the possible effects of the drug. particularly in a patient scheduled for surgery. the nurse anticipates which of the following actions?
-
Draw a blood sample for prothrombin (PT) and international normalized ratio (INR) level.
-
Administer vitamin K.
-
Draw a blood sample for type and crossmatch and request blood from the blood bank.
-
Cancel the surgery after the patient reports stopping the Coumadin one week previously.
Correct Answer
A. Draw a blood sample for prothrombin (PT) and international normalized ratio (INR) level.Explanation
The effect of Coumadin is to inhibit clotting. The next step is to check the PT and INR to determine the patient’s anticoagulation status and risk of bleeding. Vitamin K is an antidote to Coumadin and may be used in a patient who is at imminent risk of dangerous bleeding. Preparation for transfusion. as described in option C. is only indicated in the case of significant blood loss. If lab results indicate an anticoagulation level that would place the patient at risk of excessive bleeding. the surgeon may choose to delay surgery and discontinue the medication.Rate this question:

The follow lab results are received for a patient. Which of the following results are abnormal? Note: More than one answer may be correct.
-
Hemoglobin 10.4 g/dL.
-
Total cholesterol 340 mg/dL.
-
Total serum protein 7.0 g/dL.
-
Glycosylated hemoglobin A1C 5.4%.
Correct Answer(s)
A. Hemoglobin 10.4 g/dL.
A. Total cholesterol 340 mg/dL.Explanation
Normal hemoglobin in adults is 12 – 16 g/dL. Total cholesterol levels of 200 mg/dL or below are considered normal. Total serum protein of 7.0-g/dL and glycosylated hemoglobin A1c of 5.4% are both normal levels.Rate this question:

A nurse is assigned to the pediatric rheumatology clinic and is assessing a child who has just been diagnosed with juvenile idiopathic arthritis. Which of the following statements about the disease is most accurate?
-
The child has a poor chance of recovery without joint deformity.
-
Most children progress to adult rheumatoid arthritis.
-
Nonsteroidal anti-inflammatory drugs are the first choice in treatment.
-
Physical activity should be minimized.
Correct Answer
A. Nonsteroidal anti-inflammatory drugs are the first choice in treatment.Explanation
Nonsteroidal anti-inflammatory drugs are important first line treatment for juvenile idiopathic arthritis (formerly known as juvenile rheumatoid arthritis). NSAIDs require 3-4 weeks for the therapeutic anti-inflammatory effects to be realized. Half of children with the disorder recover without joint deformity. and about a third will continue with symptoms into adulthood. Physical activity is an integral part of therapy.Rate this question:

A child is admitted to the hospital several days after stepping on a sharp object that punctured her athletic shoe and entered the flesh of her foot. The physician is concerned about osteomyelitis and has ordered parenteral antibiotics. Which of the following actions is done immediately before the antibiotic is started?
-
The admission orders are written.
-
A blood culture is drawn.
-
A complete blood count with differential is drawn.
-
The parents arrive.
Correct Answer
A. A blood culture is drawn.Explanation
Antibiotics must be started after the blood culture is drawn. as they may interfere with the identification of the causative organism. The blood count will reveal the presence of infection but does not help identify an organism or guide antibiotic treatment. Parental presence is important for the adjustment of the child but not for the administration of medication.Rate this question:

A two-year-old child has sustained an injury to the leg and refuses to walk. The nurse in the emergency department documents swelling of the lower affected leg. Which of the following does the nurse suspect is the cause of the child’s symptoms?

-
Bruising of the gastrocnemius muscle.
-
Possible fracture of the radius.
-
No anatomic injury. the child wants his mother to carry him.
Correct Answer
A. Possible fracture of the tibia.Explanation
The child’s refusal to walk. combined with swelling of the limb is suspicious for fracture. Toddlers will often continue to walk on a muscle that is bruised or strained. The radius is found in the lower arm and is not relevant to this question. Toddlers rarely feign injury to be carried. and swelling indicates a physical injury.Rate this question:

-
Regular developmental screening is important to avoid secondary developmental delays.
-
Cerebral palsy is caused by injury to the upper motor neurons and results in motor dysfunction. as well as possible ocular and speech difficulties.

Developmental milestones may be slightly delayed but usually will require no additional intervention.
-
Parent support groups are helpful for sharing strategies and managing health care issues.
Correct Answer(s)
A. Regular developmental screening is important to avoid secondary developmental delays.
A. Cerebral palsy is caused by injury to the upper motor neurons and results in motor dysfunction. as well as possible ocular and speech difficulties.
A. Parent support groups are helpful for sharing strategies and managing health care issues.Explanation
Delayed developmental milestones are characteristic of cerebral palsy. so regular screening and intervention is essential. Because of injury to upper motor neurons. children may have ocular and speech difficulties. Parent support groups help families to share and cope. Physical therapy and other interventions can minimize the extent of the delay in developmental milestones.Rate this question:

A child has recently been diagnosed with Duchenne’s muscular dystrophy. The parents are receiving genetic counseling prior to planning another pregnancy. Which of the following statements includes the most accurate information?
-
Duchenne’s is an X-linked recessive disorder. so daughters have a 50% chance of being carriers and sons a 50% chance of developing the disease.
-
Duchenne’s is an X-linked recessive disorder. so both daughters and sons have a 50% chance of developing the disease.
-
Each child has a 1 in 4 (25%) chance of developing the disorder.
-
Sons only have a 1 in 4 (25%) chance of developing the disorder.
Correct Answer
A. Duchenne’s is an X-linked recessive disorder. so daughters have a 50% chance of being carriers and sons a 50% chance of developing the disease.Explanation
The recessive Duchenne gene is located on one of the two X chromosomes of a female carrier. If her son receives the X bearing the gene he will be affected. Thus. there is a 50% chance of a son being affected. Daughters are not affected. but 50% are carriers because they inherit one copy of the defective gene from the mother. The other X chromosome comes from the father. who cannot be a carrier.Rate this question:
