A nurse is reviewing the laboratory data of a client who is receiving filgrastim. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the treatment?
INR
BUN
WBC count
Potassium level
The Correct Answer is C
Choice A Reason:
INR (International Normalized Ratio) is incorrect. INR is a measurement used to monitor the effects of anticoagulants like warfarin. It assesses the blood's ability to clot. Filgrastim does not directly affect INR levels, so monitoring INR would not provide information about the effectiveness of filgrastim in stimulating white blood cell production.
Choice B Reason:
BUN (Blood Urea Nitrogen) is incorrect. BUN levels primarily indicate kidney function and hydration status. They are not directly influenced by filgrastim treatment. Monitoring BUN is essential for assessing kidney function but does not reflect the effectiveness of filgrastim therapy in increasing white blood cell counts.
Choice C Reason:
WBC count is correct. Filgrastim is a medication that stimulates the production of white blood cells (WBCs), particularly neutrophils. Therefore, the key laboratory value to monitor for assessing the effectiveness of filgrastim therapy is the WBC count. An increase in the WBC count, particularly in the neutrophil count, signifies the intended therapeutic effect of filgrastim in boosting the immune system's response by increasing the production of these infection-fighting cells.
Choice D Reason:
Potassium level is incorrect. Potassium levels are crucial for heart and muscle function. While certain medications might affect potassium levels, filgrastim's primary action is on stimulating white blood cell production and does not directly impact potassium levels. Monitoring potassium levels is essential for overall health but does not specifically indicate the effectiveness of filgrastim treatment.

Correct Answer is D
Explanation
Choice A Reason:
Weight gain is incorrect. Weight gain is typically associated with fluid volume excess rather than deficit. In heart failure, fluid retention can lead to weight gain due to excess fluid accumulation in the body.
Choice B Reason:
Distended neck veins is incorrect. Distended neck veins are a sign of fluid volume excess, commonly seen in heart failure due to increased venous pressure and fluid retention.
Choice C Reason:
Shortness of breath is incorrect.: Shortness of breath is often associated with fluid accumulation in the lungs, known as pulmonary edema, which is a manifestation of fluid volume excess or fluid overload in heart failure.
Choice D Reason:
Elevated hematocrit level is correct. Furosemide is a diuretic that promotes diuresis (increased urine output), leading to fluid loss. When a client experiences fluid volume deficit or dehydration due to increased diuresis, there is a concentration of red blood cells in the blood, resulting in an elevated hematocrit level. This occurs because the blood becomes more concentrated when there's less fluid volume available.
Correct Answer is A
Explanation
Choice A Reason:
Hypokalemia is correct. Hydrochlorothiazide is a thiazide diuretic that promotes the excretion of sodium and water in the kidneys, leading to increased urine production. However, it can also cause the loss of potassium (hypokalemia) as a side effect. Hypokalemia can manifest with symptoms such as muscle weakness, fatigue, irregular heart rhythms, and muscle cramps.
Choice B Reason:
Hypermagnesemia is incorrect. Hydrochlorothiazide typically promotes the loss of magnesium rather than causing elevated magnesium levels.
Choice C Reason:
Hypernatremia is incorrect. Hydrochlorothiazide is more likely to cause a decrease in sodium levels (hyponatremia) rather than an increase (hypernatremia).
Choice D Reason:
Hypocalcemia is incorrect. Hydrochlorothiazide can cause increased excretion of calcium but it's not a common adverse effect compared to the loss of potassium (hypokalemia).
