Patient-controlled analgesia delivers IV opioid on patient demand. NCLEX tests the only-patient-pushes-button rule and monitoring.

Setup

Loading dose, basal rate (sometimes), demand dose, lockout interval, 1-hour max.

PCA-by-proxy (family/staff pushing) bypasses the safety feature that the patient can't push when over-sedated. Sentinel event.

RR, sedation level, pain. Frequent in first 24h. Pulse ox if at risk.

Wrong concentration in cassette. Pump programming error. Family pushing button.

Patient education on use. Family told they cannot push button. Bedside reminder signage.

What to do if patient over-sedated?

Stop PCA. Naloxone if respiratory depression. Notify provider.

Basal rate for opioid-naive?

Generally avoid, increases over-sedation risk. Demand-only safer.
