Question

Reviewing the record of a client taking warfarin for chronic atrial fibrillation, what value should the nurse identify as a desired outcome for therapy?

a) PTT of 45 seconds
b) INR of 2.5
c) Platelet count of 150,000/mm³
d) Hemoglobin level of 12 g/dL

Answer 1

The desired outcome for a client taking warfarin for chronic atrial fibrillation is an INR of 2.5.

Step-by-step explanation:

The desired outcome for a client taking warfarin for chronic atrial fibrillation is an INR of 2.5. Warfarin is an anticoagulant medication that works by inhibiting the synthesis of certain clotting factors in the liver. The INR (International Normalized Ratio) is a measure of the blood's ability to clot and is used to monitor the effectiveness of warfarin therapy. A target INR of 2.5 is commonly recommended for patients with chronic atrial fibrillation.
