A client is on a blood thinner medication and requires weekly INR values. The nurse expects to see an INR of 2-2.5 times the normal range so she would anticipate what value:

below 1.0

1.0-2.0

above 3.0

2.0-3.0

Answer and Explanation

The Correct Answer is D

A. Below 1.0: Too low, indicating inadequate anticoagulation, increasing the risk of clot formation.

B. 1.0-2.0: Subtherapeutic, meaning the medication is not effectively preventing clot formation.

C. Above 3.0: Too high, increasing the risk of bleeding complications

D. 2.0-3.0: The normal INR (International Normalized Ratio) for a client not on anticoagulants is 0.8-1.2. For clients on warfarin or other blood thinners, the target therapeutic range is typically 2.0-3.0, which reduces the risk of blood clots while minimizing the risk of bleeding. Some conditions, such as mechanical heart valves, may require a higher target range (2.5-3.5).
