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:
Decreased respiratory rate is incorrect. Heparin administration and an elevated aPTT typically do not directly cause a decrease in respiratory rate. Respiratory rate changes might occur due to other factors such as respiratory conditions, pain, or medications affecting the respiratory center, but they are not commonly linked to heparin therapy.
Choice B Reason:
Increased blood pressure is incorrect. Heparin therapy and an elevated aPTT do not typically result in increased blood pressure. Heparin's primary effect is on preventing blood clotting, and while it can indirectly affect blood pressure by preventing clot formation, it doesn't typically cause a significant increase in blood pressure.
Choice C Reason:
Decreased temperature is incorrect. Heparin therapy and an elevated aPTT do not generally cause a decrease in body temperature. Changes in body temperature might occur due to various reasons such as infection, environmental factors, or certain medications, but they are not directly linked to heparin administration.
Choice D Reason:
Increased pulse rate is correct. An increased pulse rate can be an early indicator of bleeding or a potential side effect of heparin administration. Heparin's anticoagulant effect might predispose individuals to bleeding, so an increased pulse rate could indicate a response to potential bleeding complications rather than a direct effect of heparin itself.
Correct Answer is C
Explanation
Choice A Reason:
There's no requirement to lie down for an hour after administering nasal cyanocobalamin.
Choice B Reason:
The duration of treatment might vary depending on the healthcare provider's instructions and the client's response, so stating a specific duration of 6 months may not be accurate.
Choice C Reason:
"Administer the medication into one nostril once per week. “Nasal cyanocobalamin is typically used weekly for the treatment of pernicious anemia. It's administered into one nostril as directed by a healthcare provider. This method allows for the absorption of vitamin B12 through the nasal mucosa.
Choice D Reason:
Using a nasal decongestant before administering the medication is not typically part of the recommended administration protocol for nasal cyanocobalamin.
