A nurse is caring for a client who is using a patient-controlled analgesia (PCA) pump for postoperative pain management. The nurse enters the room to find the client asleep and his partner pressing the button to dispense another dose. Which of the following responses should the nurse make?

Rationale: A. Only the client should administer PCA medication. Allowing others to do so increases the risk of oversedation and respiratory depression. B. This is a non-therapeutic response that can sound judgmental and does not address safety. C. This encourages unsafe practice because only the patient should control PCA administration. D. PCA pumps are designed for the client to self-administer analgesia based on their pain level. This prevents oversedation and ensures safe use of opioids.
