There are several different types of pain.
Which type of pain occurs after the loss of a body part from an amputation?

Choice A rationale:
Endorphins are capable of reducing pain in both physiological and psychological conditions, so this statement is inaccurate.
Choice B rationale:
Endorphins are often described as natural morphine-like compounds, but they are not enzymes. They are neuropeptides produced by the body, which bind to opioid receptors and act as natural painkillers.
Choice D rationale:
Endorphins can reduce pain in response to various stressors, whether they are physiological or psychological. They play a role in the body's response to stress and pain. Therefore, this statement is not accurate.

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.
