The advantage of using patient-controlled analgesia (PCA) following a cesarean birth is that the patient:
1. Receives a bolus of the analgesia when pressing the button.
2. Experiences pain relief within 30 minutes.
3. Feels a greater sense of control, and is less dependent on the nursing staff.
4. Can deliver as many doses of the medication as needed.
3
Rationale 1: The bolus is given by the healthcare provider at the beginning of therapy, and is not repeated.
Rationale 2: The patient experiences pain relief within 30 minutes of receiving oral pain medications. IV pain medications provide rapid pain relief.
Rationale 3: The preset pump has a time lockout, so the patient cannot deliver another dose until a specified period has elapsed, but it allows the patient to do the administering.
Rationale 4: The patient is locked out of delivering as many doses as might be desired by the preset time lockout in the pump.
