A patient experiencing pain states that guided imagery has made the pain more manageable in the past.
To assist this patient, the nurse should:.

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.

Choice A rationale:

Offering an ice pack to place on the neck would not be an appropriate response in this situation. The patient has already complained that the ice massage is making the pain worse, so providing additional cold application may exacerbate their discomfort.

Choice B rationale:

The most helpful response in this scenario is to acknowledge the patient's discomfort and stop the cold application. Not everyone responds positively to cold therapy, and it's essential to respect the patient's feedback and provide alternative methods for pain relief.

Choice C rationale:

Alternating hot and cold applications may be helpful for some patients, but in this case, the patient has already expressed that the ice massage is exacerbating their pain. Suggesting this approach without addressing the patient's immediate concern is not appropriate.

Choice D rationale:

While it's true that the discomfort from the ice massage may subside in a few minutes, it's important to prioritize the patient's comfort and address their pain immediately. Continuing an intervention that is causing increased pain is not in the patient's best interest.
