What statement about patient-controlled analgesia (PCA) should a nurse include in teaching?

Patient-controlled analgesia (PCA) allows patients to self-administer pain medication with a programmable pump, granting them control over their pain management. Teaching patients that they should push the button before engaging in physical activity is important because it helps preemptively manage pain, ensuring they are comfortable enough to participate in activities like walking or physical therapy. This proactive approach can enhance their recovery experience and promote mobility, which is vital post-surgery.

Other options do not accurately reflect the intended use or safety of PCA. For instance, using PCA is not restricted to when a patient is in bed; it can be utilized while moving or engaging in activities, provided the patient is stable and able to safely manage the equipment. Additionally, PCA can be very effective after surgery for pain management, rather than being contraindicated. Its administration is not appropriate for everyone; specific assessments must be performed to determine if it is suitable based on the patient's condition and ability to use the system safely.
