A nurse is assessing a client who has obstructive sleep apnea (OSA). Which of the following findings should the nurse expect?

Choice A rationale:

Sleep influences memory. During the different stages of sleep, particularly during deep sleep (slow-wave sleep and rapid eye movement sleep), the consolidation of memories occurs. This means that sleep plays a critical role in memory function.

Choice B rationale:

Sleep influences mood. A lack of sleep or disrupted sleep patterns can lead to mood disturbances, including irritability, anxiety, and depression. Adequate sleep is essential for maintaining a stable and positive mood.

Choice C rationale:

Sleep influences cognitive function. Sleep is crucial for cognitive processes such as attention, problem-solving, and decision-making. Sleep deprivation can impair cognitive function, leading to reduced alertness and cognitive performance.

Choice D rationale:

Sleep influences the secretion of various hormones. Sleep plays a significant role in regulating hormones such as growth hormone, cortisol, and melatonin. Disruptions in sleep can lead to imbalances in these hormones, affecting various physiological processes.

Choice E rationale:

Sleep influences immune function. Adequate sleep is essential for a healthy immune system. During sleep, the immune system is actively engaged in repairing and protecting the body. Sleep deprivation can weaken the immune response, making individuals more susceptible to infections.

Choice F rationale:

Sleep influences body temperature. The body's core temperature fluctuates during the sleep-wake cycle, with the lowest point typically occurring during the night when we are asleep. This temperature regulation is essential for sleep quality and overall health.

Choice G rationale:

Sleep influences renal function. Sleep has an impact on various physiological processes, including renal function. The kidneys play a role in regulating blood pressure and electrolyte balance, which can be influenced by sleep patterns.

The correct answer is choice B. "Why do you think your husband needs more medication when he is asleep?"

Choice A rationale:

"Your husband should decide when more medication is needed.” This response is incorrect because it implies that the partner has the authority to decide when the client needs pain medication, which violates the purpose of a PCA pump. A PCA pump is specifically designed for client-controlled pain management, ensuring that the patient, not anyone else, controls when they receive pain medication. Allowing someone else to press the button can lead to overmedication and safety risks.

Choice B rationale:

"Why do you think your husband needs more medication when he is asleep?" This response is correct because it prompts the partner to reflect on their actions and provides an opportunity for the nurse to educate about the proper use of PCA pumps. It addresses the immediate issue without being confrontational and opens the door for further discussion on the importance of client safety and correct PCA use.

Choice C rationale:

"It's a good idea to help make sure your husband can sleep comfortably.” This response is incorrect as it endorses inappropriate and unsafe behavior. It encourages the partner to continue pressing the PCA button, risking the client's safety due to potential overmedication, which can lead to severe complications, such as respiratory depression.

Choice D rationale:

"Next time you think he needs more medication, call me and I'll push the button.” This response is incorrect because it contradicts PCA protocols and removes the control from the client. The nurse is responsible for monitoring the client’s pain and safety, not administering medication upon another person’s request. This approach also increases the risk of dosing errors and undermines the purpose of patient-controlled analgesia.
