A patient taking warfarin is prescribed a nonsteroidal anti-inflammatory drug. Which adverse effect should the nurse monitor most closely?
Correct answer: B. Bleeding such as black stools or gum bleeding
- A. Severe constipation and urinary retention
- B. Bleeding such as black stools or gum bleeding
- C. Increased appetite and rapid weight gain

Explanation
Warfarin impairs clotting, while many nonsteroidal anti-inflammatory drugs increase gastrointestinal irritation and affect platelet function. Together they can increase bleeding risk, so the nurse should monitor for bleeding and report it promptly.
