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. Monitoring potassium level (
A), BUN (
B), and INR (
C) are not directly related to evaluating the effectiveness of filgrastim treatment. Potassium level is typically monitored for cardiac function, BUN for kidney function, and INR for monitoring anticoagulant therapy.
Therefore, the WBC count is the most appropriate laboratory value to assess the response to 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 is a potential complication of parenteral nutrition. Administering IV dextrose is the appropriate action to increase the client's blood sugar levels quickly. Discontinuing the infusion (choice
A) would further decrease glucose supply. Warming formula (choice
C) is not directly related to treating hypoglycemia. Obtaining arterial blood gases (choice
D) is not necessary for managing hypoglycemia.
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, the body's blood pressure drops significantly, leading to hypotension. Dopamine is a vasopressor that helps increase blood pressure by constricting blood vessels.
Therefore, if the client's blood pressure remains low despite being on dopamine, it indicates that the current rate of infusion is not sufficient to maintain adequate perfusion to vital organs. Increasing the rate of infusion would help improve blood pressure and perfusion.
Choices A, C, and D are incorrect as they are not directly related to the need for increasing the dopamine infusion rate in septic shock.
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 antiplatelet effects. Warfarin is an anticoagulant that works by inhibiting blood clot formation. Combining it with Ginkgo biloba, which also has anticoagulant properties, can lead to excessive bleeding. Coenzyme Q10 (
B), valerian (
C), and probiotics (
D) do not have significant interactions with warfarin.
Therefore, Ginkgo biloba is contraindicated for concurrent use with warfarin due to the increased risk of bleeding.
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 because propranolol is a beta-blocker that can slow down the heart rate. A heart rate of 56/min may indicate bradycardia, which can be a sign of overdose or adverse reaction to the medication. The nurse should intervene by assessing for symptoms of bradycardia and potentially contacting the healthcare provider.
Choices B, C, and D are within normal ranges and do not require immediate intervention.
Choice B indicates adequate oxygen saturation, choice C shows normal respiratory rate, and choice D represents a slightly low but acceptable blood pressure reading.
