Question 1 of 5
A 46-year-old man underwent surgery to remove a glioma of the left brain lobe. An intravenous infusion of a drug was started to induce controlled hypotension to minimize blood loss during surgery. Which of the following drugs would be most appropriate for this purpose?
Correct Answer: D
Rationale: The correct answer is D: Nitroprusside. Nitroprusside is a potent vasodilator that can rapidly induce controlled hypotension by relaxing smooth muscle in blood vessels. This helps in minimizing blood loss during surgery. Labetalol (A) is a non-selective beta-blocker with alpha-blocking activity, which may not provide rapid hypotension. Hydralazine (B) is a direct vasodilator that can cause reflex tachycardia and may not be as effective in controlled hypotension. Nifedipine (C) is a calcium channel blocker primarily used for hypertension but does not provide rapid hypotension like nitroprusside.
