Question

An opioid-naive 78-year-old client is prescribed morphine PCA with a continuous basal infusion after hip surgery. Which action should the nurse take before starting the PCA?

A continuous basal opioid infusion increases respiratory-depression risk in opioid-naive clients, and advanced age adds further risk. The nurse should hold initiation and clarify the prescription, advocating for an individualized plan such as demand-only dosing with multimodal analgesia and appropriate monitoring.

In-depth explanation

Clinical reasoning summary
The PCA demand button provides a partial safety mechanism because a sedated client stops pressing it; a basal infusion bypasses that mechanism. In an opioid-naive older adult, hold initiation and clarify the basal rate before therapy begins.
