One thing the nurse would ask the patient to do to try to locate the reason for her insomnia is to:.

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 A rationale:
Patient-controlled analgesia (PCA) is a method of pain management that allows the patient to administer their own pain medication within specified limits, but it doesn't reduce the workload of the nurse. The nurse is responsible for setting up and monitoring the PCA pump, educating the patient, assessing their pain, and ensuring safety. Therefore, this choice is incorrect.
Choice B rationale:
PCA does not completely eliminate pain. It provides the patient with control over their pain relief by allowing them to self-administer medication within preset limits. However, it does not guarantee the complete absence of pain. Pain relief is provided within a safe dosage range, but some level of pain may still be experienced. Therefore, this choice is incorrect.
Choice C rationale:
PCA does not eliminate the risk of adverse drug effects entirely. The nurse must monitor the patient for signs of adverse effects, such as respiratory depression or sedation. While the patient has control over medication administration, there are still risks associated with opioid analgesics. Therefore, this choice is incorrect.
Choice D rationale:
The principal advantage of using patient-controlled analgesia (PCA) is that it reduces patient anxiety about pain by giving the patient more control over its management. This choice is correct because PCA empowers the patient to self-administer pain medication when needed, which can lead to better pain control and reduced anxiety. The nurse sets safe dosage limits and monitors the patient, ensuring safety while providing a sense of control.
