Warfarin is not used to prevent angina pectoris, which is typically managed with nitrates, beta-blockers, or calcium channel blockers.
Choice C rationale
Warfarin is not used to treat bradycardia, which is usually managed with medications like atropine or pacemaker implantation.

Correct Answer is A
Explanation
Choice A rationale
Prazosin, an alpha-blocker, is often started at the lowest dose and taken at night to minimize the risk of orthostatic hypotension, a sudden drop in blood pressure upon standing.
Choice B rationale
Starting prazosin at the highest dose is not recommended due to the risk of severe orthostatic hypotension, which can lead to dizziness and fainting.
Choice C rationale
It is important to monitor blood pressure with the first dose of prazosin to assess the patient's response and avoid significant drops in blood pressure.
Choice D rationale
Prazosin may take several weeks to achieve full therapeutic effect. It does not control hypertension within a week.
Correct Answer is D
Explanation
Choice A rationale
Furosemide is a loop diuretic that acts on the ascending limb of the loop of Henle, not the distal tubule.
Choice B rationale
Spironolactone is a potassium-sparing diuretic that works on the collecting ducts and late distal tubules, not the distal tubule.
Choice C rationale
Mannitol is an osmotic diuretic that acts on the proximal tubule and the descending limb of the loop of Henle, not the distal tubule.
Choice D rationale
Hydrochlorothiazide is a thiazide diuretic that works on the distal convoluted tubule, making it the correct answer.
