Med Surg Cardiovascular Test Bank Questions
Question 1 of 5
The client is taking a class IA anti-arrhythmic agent. What might be the drug the client is taking? Select all that apply.
Correct Answer: C
Rationale: The correct answer is C: Procainamide. Class IA anti-arrhythmic agents, like Procainamide, work by blocking sodium channels, prolonging action potential duration. Metoprolol (A) is a beta-blocker, not a class IA agent. Disopyramide (B) is a class IA agent, but it acts primarily by blocking potassium channels. Morcizine (D) is a class IC anti-arrhythmic agent, not a class IA agent. Therefore, Procainamide is the most likely choice among the options provided.
Question 2 of 5
The nurse is reviewing the client’s medication list before giving IV heparin. What drug has a drug-drug interaction with heparin?
Correct Answer: D
Rationale: The correct answer is D: Aspirin. Aspirin interacts with heparin by increasing the risk of bleeding due to their combined antiplatelet effects. Heparin is an anticoagulant, while aspirin is an antiplatelet agent. The combination can lead to excessive bleeding. A: Acetaminophen does not have a significant drug-drug interaction with heparin. B: ACE inhibitors do not have a direct interaction with heparin. C: Nitroprusside is not typically associated with a drug-drug interaction with heparin.
Question 3 of 5
The client is on a blood thinner and is experiencing tinnitus. Which drug is the client likely taking?
Correct Answer: D
Rationale: The correct answer is D: Warfarin. Warfarin is known to cause tinnitus as a side effect due to its anticoagulant properties affecting blood flow in the inner ear. Pradaxa (A) is less likely to cause tinnitus. Aspirin (B) can cause tinnitus but is not a blood thinner. Heparin (C) is not associated with tinnitus. In summary, Warfarin is the likely drug causing tinnitus due to its anticoagulant effects on inner ear blood flow.
Question 4 of 5
The client is to start taking simvastatin for cholesterol reduction. What does the nurse say to educate the client about the drug?
Correct Answer: A
Rationale: The correct answer is A because simvastatin is more effective when taken at night, as cholesterol synthesis peaks in the early hours of the morning. This timing aligns with the drug's mechanism of action. Choice B is incorrect because simvastatin can be taken with any beverage, including orange juice. Choice C is incorrect because simvastatin can be taken with or without food. Choice D is incorrect because there are no interactions between simvastatin and aspirin.
Question 5 of 5
The client has a history of atrial fibrillation and is taking quinidine. Which of the following drugs will have a drug-drug interaction with quinidine?
Correct Answer: B
Rationale: The correct answer is B: Lanoxin. Quinidine can increase the levels of Lanoxin (digoxin) in the bloodstream by inhibiting its clearance, leading to potential toxicity. Lasix (A) does not have a significant drug interaction with quinidine. Inderal (C) may interact with quinidine, but it is less common compared to Lanoxin. Dyazide (D) is a combination of hydrochlorothiazide and triamterene, which does not have a significant interaction with quinidine.
