The nurse will request an order for which?

Platelet level.
The Correct Answer is C

Checking vitamin K levels doesn't directly monitor warfarin's effect.

PTT and aPTT assess heparin, not warfarin.
Choice C rationale
INR specifically measures warfarin's effectiveness and safety.

Platelet levels don't monitor the anticoagulant effect of warfarin.
