A patient presents with thirst, dry skin, and decreased urine output. What diagnosis would you suspect?
- A.
Hypokalemia
- B.
Hyponatremia
- C.
Fluid volume excess
- D.
Fluid volume deficit
Correct Answer
D. Fluid volume deficitExplanation
Based on the symptoms presented by the patient, such as thirst, dry skin, and decreased urine output, the most likely diagnosis would be fluid volume deficit. Thirst is a common symptom of dehydration, which is a characteristic of fluid volume deficit. Dry skin can also be a result of decreased fluid intake or loss. Decreased urine output is another indication of dehydration, as the body tries to conserve water. Hypokalemia and hyponatremia are conditions related to electrolyte imbalances and may not be the primary cause of the symptoms. Fluid volume excess, on the other hand, would present with symptoms like edema and weight gain, which are not mentioned in the patient's presentation.Rate this question:

Tap the cheek about two (2) centimeters anterior to the ear lobe.
- C.
Check the serum calcium and magnesium levels.
- D.
Prepare to administer calcium gluconate IVP.
Correct Answer
B. Tap the cheek about two (2) centimeters anterior to the ear lobe.Explanation
After a thyroidectomy, there is a risk of damage to the parathyroid glands, which can lead to hypocalcemia. Numbness and tingling around the mouth and fingertips are classic signs of hypocalcemia. Tapping the cheek about two centimeters anterior to the ear lobe is known as Chvostek's sign and is a quick and simple test to assess for hypocalcemia. This intervention should be implemented first to confirm the presence of hypocalcemia before notifying the healthcare provider or administering calcium gluconate. Checking the serum calcium and magnesium levels is also important but takes longer for results to come back, so it is not the first intervention.Rate this question:

A nurse is assigned to care for a group of clients. On review of the clients' medical records, the nurse determines that which client is at risk for excess fluid volume?
- A.
The client taking diuretics
- B.
The client with renal failure
- C.
The client with an ileostomy
- D.
The client who requires gastrointestinal suctioning
Correct Answer
B. The client with renal failureExplanation
The client with renal failure is at risk for excess fluid volume because renal failure impairs the kidneys' ability to properly filter and excrete fluids from the body. This can lead to fluid retention and an imbalance in fluid volume, resulting in excess fluid accumulation in the body. The other options, such as the client taking diuretics, the client with an ileostomy, and the client who requires gastrointestinal suctioning, do not necessarily indicate a risk for excess fluid volume.Rate this question:

The nurse is caring for a client with congestive heart failure. On assessment, the nurse notes that the client is dyspneic and that crackles are audible on auscultation. The nurse suspects excess fluid volume. What additional signs would the nurse expect to note in this client if excess fluid volume is present?
- A.
Weight loss
- B.
Flat neck and hand veins
- C.
An increase in blood pressure
- D.
A decreased central venous pressure (CVP)
Correct Answer
C. An increase in blood pressureExplanation
If the nurse suspects excess fluid volume in a client with congestive heart failure, they would expect to note an increase in blood pressure. Excess fluid volume can lead to increased blood volume, which in turn increases the pressure within the blood vessels. This can result in elevated blood pressure readings. Weight loss would not be expected as excess fluid volume typically leads to weight gain. Flat neck and hand veins would also not be expected as these are signs of decreased fluid volume. A decreased central venous pressure (CVP) would also not be expected as excess fluid volume would cause an increase in CVP.Rate this question:

- C.
Hyperactive bowel sounds
- D.
Increased specific gravity of urine
Correct Answer
C. Hyperactive bowel soundsExplanation
Hyponatremia is a condition characterized by low levels of sodium in the blood. This can lead to various symptoms, including neurologic changes and gastrointestinal disturbances. Hyperactive bowel sounds are a common manifestation of hyponatremia. This occurs due to increased peristalsis in the intestines, leading to increased bowel sounds. Other signs of hyponatremia may include nausea, vomiting, headache, confusion, seizures, and muscle cramps. Dry skin, decreased urine output, and increased specific gravity of urine are not typically associated with hyponatremia.Rate this question:

Bedridden patients are at risk for developing
- A.
Hypocalcemia
- B.
Hypernatremia
- C.
Hypercalcemia
- D.
Hypokalemia
Correct Answer
C. HypercalcemiaExplanation
Bedridden patients are at risk for developing hypercalcemia. This is because when patients are immobile and confined to bed, their bones are not being regularly stressed, leading to decreased bone turnover. This can result in calcium being released from the bones into the bloodstream, causing elevated levels of calcium in the blood. Additionally, bedridden patients may have limited exposure to sunlight, which can decrease vitamin D production and impair calcium absorption. Overall, the lack of mobility and sunlight exposure in bedridden patients increases their risk for developing hypercalcemia.Rate this question:
