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, a class IA anti-arrhythmic agent. Procainamide is known for its sodium channel blocking properties, which helps to stabilize cell membranes and prevent abnormal electrical activity in the heart. Metoprolol (A) is a beta-blocker, Disopyramide (B) is a class IA anti-arrhythmic agent but not commonly used, and Morcizine (D) is a class IC anti-arrhythmic agent. Therefore, C is the correct choice for a class IA anti-arrhythmic agent.
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 can increase the risk of bleeding when taken with heparin, which is also an anticoagulant. This combination may lead to excessive bleeding. Acetaminophen (A) does not have a significant drug interaction with heparin. ACE inhibitors (B) and Nitroprusside (C) are not known to have interactions with heparin that increase bleeding risk.
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 an anticoagulant that can lead to tinnitus as a side effect due to its impact on blood clotting. Pradaxa (A) and Heparin (C) are also anticoagulants but are less likely to cause tinnitus. Aspirin (B) is an antiplatelet drug and is not typically associated with tinnitus. Therefore, considering the client is on a blood thinner and experiencing tinnitus, Warfarin is the most likely culprit.
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: It should be taken at night. Simvastatin is more effective when taken at night because cholesterol synthesis peaks during the night. Taking it at night aligns with the body's natural rhythm and enhances its efficacy. Choice B is incorrect because there is no known interaction between simvastatin and orange juice. Choice C is incorrect because simvastatin can be taken with or without food, so an empty stomach is not necessary. Choice D is incorrect because there is no significant interaction 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 Lanoxin levels, leading to toxicity due to shared metabolic pathways. Lasix (A), Inderal (C), and Dyazide (D) do not have significant drug interactions with quinidine. Lasix is a diuretic, Inderal is a beta-blocker, and Dyazide is a combination diuretic, so they do not interact with quinidine in the same way as Lanoxin.
