Answer 1

The nurse would monitor the International Normalized Ratio (INR) to determine a therapeutic response to warfarin.

Step-by-step explanation:

The nurse would monitor the International Normalized Ratio (INR) to determine a therapeutic response to warfarin. INR is a lab test that measures the speed of a specific pathway of coagulation and compares it to normal. A higher INR indicates a longer time for blood to clot, which is the desired therapeutic effect of warfarin.
