Correct Answer is D

Explanation

Choice A rationale

Bradycardia is not a common complication of ondansetron (Zofran). Instead, one should watch for changes in heart rhythm such as QT interval prolongation.

Choice B rationale

Absence of nausea indicates the desired effect of ondansetron, not a complication.

Choice C rationale

Ondansetron is associated with prolongation of the QT interval, not shortening. QT interval shortening is not a recognized complication.

Choice D rationale

Prolonged QT interval is a known complication of ondansetron and can increase the risk of life-threatening arrhythmias. .

A. This medication prevents venous thrombosis. B. This medication prevents angina pectoris. C. This medication is to treat bradycardia. D. This medication is to treat hypertension.

Correct Answer is A

Explanation

Choice A rationale

Warfarin is an anticoagulant that is used to prevent venous thrombosis and thromboembolic events by inhibiting the synthesis of vitamin K-dependent clotting factors.

Choice B rationale

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.

Choice D rationale

Warfarin is not used to treat hypertension. Antihypertensive medications such as ACE inhibitors, beta-blockers, or diuretics are used for this purpose.
