Choice A rationale:

This statement is not accurate and may confuse the client. In a Patient-Controlled Analgesia (PCA) system, a predetermined dose is delivered when the patient activates the device. The dose is usually controlled to prevent excessive medication administration.

Choice B rationale:

This statement is correct. The essence of PCA is that the patient has control over administering their pain medication within set limits or time intervals. The patient can self-administer doses when needed, ensuring effective pain management.

Choice C rationale:

Allowing the partner to push the PCA button for the patient is not recommended. PCA systems are designed to be controlled by the patient themselves to prevent potential overdosing. Involving someone else in the administration can lead to safety concerns.

Choice D rationale:

PCA systems do not deliver medication into the muscle. They typically deliver medication intravenously (IV) or subcutaneously. This statement is inaccurate and could lead to misconceptions about how the PCA system works.

Choice C rationale:
