Correct Answer is D

Explanation

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).

Explanation

A. Notify the nurse manager: Reporting is important, but assessing the patient comes first.

B. Observe the client and collect data: Patient safety is the priority. The nurse must assess the client for adverse effects first before notifying anyone.

C. Call the client’s provider: The provider needs to be informed, but only after assessing the client’s condition.

D. Complete an incident report: Documentation is essential but comes after assessing and ensuring client safety.
