Correct Answer is {"dropdown-group-1":"B"}

Explanation

A. Minutes: This is too short a timeframe for warfarin's effect. It takes longer for the body's existing clotting factors to be depleted.

B. Days: This medication works by inhibiting the production of vitamin K-dependent clotting factors in the liver. As existing clotting factors are used up and new ones aren't produced as efficiently, it takes time for the anticoagulant effect to become significant.

C. Weeks: While the full effect might take some time (around 3-5 days), several weeks is an overestimation for most patients.

D. Hours: A few hours might show some initial effect, but it's not enough time for a substantial anticoagulant effect. It usually takes at least a day or two.

Correct Answer is C

Explanation

A. Nausea and vomiting: Nausea and vomiting can occur with epoetin alfa, but it's not the most common side effect.

B. Orthostatic hypotension: This is not a common side effect of epoetin alfa. Orthostatic hypotension is a decrease in blood pressure upon standing.

C. Hypertension: Epoetin alfa stimulates the production of red blood cells. When the red blood cell count increases too quickly, it can lead to increased blood pressure, which is the most common adverse effect.

D. Dizziness: Dizziness can occur with epoetin alfa, but it's less common than hypertension.
