Signs of fentanyl patch overdose are:.

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:

Going to bed hungry or overly full can interfere with sleep. When you're too hungry, your body may be uncomfortable and unable to relax, making it difficult to fall asleep. Conversely, going to bed overly full can lead to discomfort, and indigestion, and may result in disrupted sleep. Therefore, it does not help the patient reach REM (Rapid Eye Movement) sleep faster.

Choice B rationale:

Overeating or going to bed hungry does not aid in reaching REM sleep faster. It is essential for individuals to have a balanced diet and avoid excessive hunger or fullness to promote a healthy sleep pattern. REM sleep is a stage of deep sleep that occurs cyclically throughout the night, and it is influenced by various factors, including individual sleep patterns and circadian rhythms.

Choice C rationale:

REM sleep, a stage of deep sleep, is not influenced by going to bed hungry or overly full. Instead, it is primarily regulated by the body's internal clock and sleep-wake cycles. Factors such as hunger or fullness may affect the quality of sleep but do not contribute to reaching REM sleep faster.

Choice D rationale:

False. Going to bed hungry or overly full does not have a direct impact on the patient's ability to reach REM sleep faster. REM sleep is a natural part of the sleep cycle and is influenced by various factors, such as circadian rhythms, sleep disorders, and medications, but not by the state of hunger or fullness.
