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:

Indomethacin (Indocin) is a nonsteroidal anti-inflammatory medication (NSAID). It is commonly used to reduce inflammation and relieve pain, making it a suitable choice for pain management in conditions where inflammation plays a role, such as arthritis or musculoskeletal injuries.

Choice B rationale:

Indomethacin is not typically categorized as an adjuvant analgesic. Adjuvant analgesics are medications that are not primarily designed for pain relief but may enhance the effects of analgesics when used in combination.

Choice C rationale:

Indomethacin is not a COX-2 inhibitor. COX-2 inhibitors are a specific class of NSAIDs that target the COX-2 enzyme while sparing COX-1. Indomethacin is a traditional NSAID that inhibits both COX-1 and COX-2.

Choice D rationale:

Indomethacin is not a narcotic analgesic. Narcotic analgesics, also known as opioids, are a separate class of medications used for the management of moderate to severe pain. Indomethacin does not belong to this class and has a different mechanism of action.
