1. What is the antidote for Warfarin?
- A. Vitamin D
- B. Vitamin C
- C. Vitamin K
- D. Vitamin B6
Correct answer: C
Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.
2. A client has a new prescription for Lisinopril. Which of the following instructions should the nurse include?
- A. Avoid salt substitutes.
- B. Take this medication at bedtime.
- C. Increase your intake of potassium-rich foods.
- D. Take this medication with food.
Correct answer: A
Rationale: The correct instruction for a client prescribed Lisinopril is to avoid salt substitutes. Lisinopril, an ACE inhibitor, can lead to hyperkalemia, hence the importance of avoiding salt substitutes that may contain potassium. Instructing the client to avoid salt substitutes helps prevent potential adverse effects of increased potassium levels.
3. A healthcare provider is preparing to administer Belimumab to a client with Systemic Lupus Erythematosus. Which of the following actions should the healthcare provider plan to take?
- A. Warm the medication to room temperature before administering.
- B. Administer the medication by IV bolus over 5 minutes.
- C. Dilute the medication in a 5% dextrose and water solution.
- D. Monitor the client for hypersensitivity reactions.
Correct answer: D
Rationale: Correct Answer: Monitoring the client for hypersensitivity reactions is crucial when administering Belimumab due to its known potential for severe infusion reactions and anaphylaxis. The healthcare provider should closely observe the client during the administration to promptly identify and manage any hypersensitivity reactions that may occur. Choice A is incorrect because warming Belimumab is not necessary before administration. Choice B is incorrect as Belimumab should not be administered as an IV bolus over 5 minutes; it should be given as an IV infusion over a longer duration. Choice C is incorrect as Belimumab should not be diluted in a 5% dextrose and water solution.
4. A client reports taking Aspirin four times daily for a sprained wrist. Which of the following prescribed medications taken by the client is contraindicated with aspirin?
- A. Digoxin
- B. Metformin
- C. Warfarin
- D. Nitroglycerin
Correct answer: C
Rationale: Aspirin inhibits platelet aggregation, which can increase the effect of anticoagulants like warfarin, leading to an elevated risk of bleeding. Therefore, the concurrent use of aspirin and warfarin is generally contraindicated due to this potential interaction. Digoxin is not contraindicated with aspirin in most cases. Metformin and nitroglycerin do not have significant interactions with aspirin, making them less likely to be contraindicated in this scenario.
5. A client has a new prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?
- A. Take the medication in the morning.
- B. Increase your intake of potassium-rich foods.
- C. Expect decreased urination within the first few days.
- D. Avoid foods high in potassium.
Correct answer: B
Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Hydrochlorothiazide is a diuretic that can lead to hypokalemia by increasing potassium excretion. Therefore, instructing the client to increase their intake of potassium-rich foods is essential to prevent electrolyte imbalances and support overall health. Choices A, C, and D are incorrect. Instructing the client to take the medication in the morning is not directly related to the medication's mechanism of action. Expecting decreased urination within the first few days is not accurate as the medication is a diuretic that typically increases urination. Also, advising the client to avoid foods high in potassium would not be suitable, as increasing potassium-rich foods is necessary to counteract potential potassium depletion caused by Hydrochlorothiazide.
