Question 1 of 5
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?
Correct Answer: D
Rationale: The correct answer is D: WBC count. Filgrastim is a medication that stimulates the production of white blood cells (WBCs). Monitoring the WBC count is essential to evaluate the effectiveness of the treatment as an increase in WBC count indicates that the medication is working to boost the immune system.
A: Potassium level is not directly related to filgrastim therapy.
B: BUN (blood urea nitrogen) is not typically affected by filgrastim.
C: INR (International Normalized Ratio) is a measure of blood clotting and is not relevant to monitoring filgrastim therapy.
Therefore, the correct choice is D as it directly reflects the intended therapeutic effect of filgrastim.
Question 2 of 5
A nurse is caring for a client who is receiving parenteral nutrition and identifies that the client has hypoglycemia. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Administer IV dextrose. Hypoglycemia in a client receiving parenteral nutrition indicates low blood sugar levels, which can lead to serious complications. Administering IV dextrose is crucial to rapidly increase the client's blood glucose levels and prevent further hypoglycemia-related issues. Discontinuing the infusion (
Choice
A) would worsen the hypoglycemia. Warming formula to room temperature (
Choice
C) and obtaining arterial blood gases (
Choice
D) are not directly related to treating hypoglycemia in this scenario.
Question 3 of 5
A nurse is assessing a client who has septic shock and is receiving dopamine by continuous IV infusion. Which of the following findings indicates that the nurse should increase the rate of infusion?
Correct Answer: B
Rationale: The correct answer is B: Hypotension. In septic shock, hypotension is a common sign of inadequate tissue perfusion. Dopamine is a vasopressor that helps increase blood pressure by constricting blood vessels.
Therefore, if the client is still hypotensive despite receiving dopamine, it indicates that the current infusion rate is not sufficient to maintain adequate perfusion. Increasing the infusion rate can help improve blood pressure and perfusion.
Incorrect choices:
A: Headache - Not a direct indication of dopamine infusion rate adjustment.
C: Chest pain - Not a direct indication of dopamine infusion rate adjustment.
D: Extravasation - Indicates leakage of medication from the IV site, not a need to adjust infusion rate.
Question 4 of 5
A nurse is caring for a client who is taking warfarin and reports taking several new herbal supplements. The nurse should identify which of the following supplements is contraindicated for concurrent use with warfarin?
Correct Answer: A
Rationale: The correct answer is A: Ginkgo biloba. Ginkgo biloba can increase the risk of bleeding when taken with warfarin due to its anticoagulant properties, potentially leading to serious complications. Coenzyme Q10 (
Choice
B), Valerian (
Choice
C), and Probiotics (
Choice
D) do not have significant interactions with warfarin. Ginkgo biloba is the only supplement in the list known to interact adversely with warfarin.
Question 5 of 5
A nurse is assessing a client with hypertension who is receiving propranolol. Which of the following findings requires the nurse's intervention?
Correct Answer: A
Rationale: The correct answer is A: Heart rate of 56/min. Propranolol is a beta-blocker that can cause bradycardia as a side effect. A heart rate of 56/min is lower than the normal range, indicating bradycardia. This finding requires the nurse's intervention as it can lead to decreased cardiac output and potential complications.
Choice B (Sa02 95% on 2 L/min of oxygen) indicates adequate oxygen saturation and does not require immediate intervention.
Choice C (Respirations 22/min) falls within the normal range and does not require immediate intervention.
Choice D (Blood pressure 106/68 mm Hg) is within normal limits for a client with hypertension on propranolol and does not require immediate intervention.
