Question 1 of 5

Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which prior illness would be the most important to document in Mr. Curry's history with possible acute myocarditis?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
The client is given a calcium channel blocker. Calcium channel blockers have what effect on the heart?
Correct Answer: B
Rationale: The correct answer is B because calcium channel blockers decrease the velocity of electrical activity on the AV node, which results in a decreased heart rate and reduced conduction through the AV node. This action helps in treating conditions like hypertension and angina. A: Incorrect. Calcium channel blockers do not increase the preload on the heart; they actually reduce the workload of the heart by decreasing afterload. C: Incorrect. Calcium channel blockers do not block sodium channels in the heart muscle; they specifically target calcium channels. D: Incorrect. Calcium channel blockers do not cause vasoconstriction of coronary arteries; they often lead to vasodilation, improving coronary blood flow.
Question 4 of 5
The client is given an alpha agonist. What might it be used for?
Correct Answer: A
Rationale: The correct answer is A: For hemostasis. Alpha agonists, such as epinephrine or norepinephrine, are used for hemostasis by inducing vasoconstriction at the site of bleeding, which helps in stopping the bleeding. Option B is incorrect because alpha agonists actually cause vasoconstriction and do not dilate arteries. Option C is incorrect because alpha agonists do not dilate veins. Option D is incorrect because alpha agonists increase afterload by causing vasoconstriction.
Question 5 of 5
The nurse is reviewing the client’s medication list. Calcium channel blockers have a significant drug-drug interaction with what?
Correct Answer: A
Rationale: The correct answer is A: Digoxin. Calcium channel blockers can increase digoxin levels, leading to toxicity. Digoxin is a cardiac glycoside, and concurrent use with calcium channel blockers can potentiate its effects. The other choices (B, C, D) do not have significant drug interactions with calcium channel blockers. Theophylline is metabolized by CYP1A2, hydrochlorothiazide is a diuretic, and fentanyl is an opioid.
