Question 1 of 5
Which of the following should be avoided in Mr. Murphy's diet following bypass surgery?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 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 3 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 4 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.
Question 5 of 5
The client has stable angina. What class of drug is used to treat angina? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Organic nitrates. Organic nitrates are vasodilators that help dilate blood vessels, reducing the workload of the heart and improving blood flow to the heart muscle, thus relieving angina symptoms. Digoxin (A) is used for heart failure and arrhythmias, not angina. Adenosine (C) is used for supraventricular tachycardia, not angina. Beta blockers (D) are also used for angina, but organic nitrates are the first-line treatment due to their rapid onset of action in relieving angina symptoms.
