Which action should the practical nurse (PNA) prioritize for postoperative patient with a PCA (Patient- Controlled Analgesia) machine?

This is the correct answer because it is the most important and relevant action that the PN should do for a postoperative patient with a PCA machine. A PCA machine is a computerized device that allows the patient to self-administer a preset dose of pain medication, usually an opioid, by pressing a buton. The PCA machine is attached to an intravenous (IV) line that delivers the medication directly into the bloodstream. The PCA machine can provide effective and individualized pain relief for postoperative patients, as well as increase their sense of control and satisfaction¹². The PN should assess the pain management response of the postoperative patient with a PCA machine by monitoring their pain level, vital signs, oxygen saturation, sedation level, and side effects. The PN should use a valid and reliable pain scale, such as the numeric rating scale (NRS) or the visual analog scale (VAS), to measure the patient's pain intensity and relief. The PN should also check the settings and functioning of the PCA machine, such as the dose, lockout interval, and limit. The PN should document and report the patient's pain management response and any problems or complications with the PCA machine to the health care provider.
