The nurse assesses a patient's sleep for NREM (non-rapid eye movement) sleep because this sleep has the characteristics of:.

Choice A rationale:

Sleeping with the window open for fresh air may not be the best solution in this scenario. While fresh air can be beneficial for sleep, it might not effectively block out the noise from the freeway and the nearby apartment complex. Furthermore, depending on the climate and location, having the window open might lead to discomfort or temperature-related issues.

Choice B rationale:

Performing exercise at bedtime is not a recommended solution for someone experiencing difficulty sleeping due to external noise. Exercise before bedtime can increase alertness and make it even more challenging to fall asleep, especially if it's vigorous exercise. It may exacerbate the problem rather than alleviate it.

Choice C rationale:

Having a couple of drinks at bedtime is not a suitable solution for sleep problems. Alcohol can disrupt sleep patterns and lead to poor-quality sleep. It may help the patient fall asleep initially but can lead to frequent awakenings and a less restful night's sleep.

Choice D rationale:

The correct choice is to wear soft earplugs for sleep. Soft earplugs can effectively reduce or block out external noise, providing a quieter sleep environment. This is a practical and safe solution to address the noise issue in the patient's apartment complex. It promotes better sleep quality without any negative side effects.

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.
