A nurse is collecting data from a client who is 8 hr postoperative following an appendectomy. Which of the following manifestations is the best indication that the client needs a PRN analgesic?

Postoperative pain assessment is a critical component of nursing care following procedures such as an appendectomy. Pain is a subjective experience and is best evaluated using the client’s self-report whenever possible. Objective indicators such as vital sign changes or behavioral cues may suggest discomfort but are less reliable than the client’s own rating. Effective pain management supports healing, mobility, and prevention of postoperative complications. Rationale: A. An increased heart rate to 110/min may indicate pain but is a nonspecific physiological response that can also be caused by anxiety, hypovolemia, or other postoperative factors. Vital sign changes alone are not the most reliable indicators for administering PRN analgesics. Pain should primarily be assessed using the client’s self-report. B. Grimacing when changing positions is a behavioral indicator of pain and suggests discomfort during movement. While it supports the presence of pain, it is still an indirect sign and should be confirmed with the client’s subjective report. Behavioral cues are useful but secondary to self-reported pain levels. C. A pain score of 7 out of 10 is a direct subjective report from the client and is the most reliable indicator that analgesia is needed. Severe pain at this level can interfere with mobility, breathing, and recovery. PRN analgesics should be administered based on the client’s reported pain intensity. D. A decreased attention span may occur due to pain, fatigue, or effects of anesthesia and medications. However, it is a nonspecific finding and does not directly quantify pain severity. Therefore, it is not the best indicator for administering pain medication compared to self-reported pain.
