A nurse is assisting with teaching a class about sleep disorders. The nurse should include that which of the following conditions can cause central sleep apnea (CSA)?
Enlarged tonsils
Obesity
Opioid overdose
Deviated septum
The Correct Answer is C
Choice A reason : Enlarged tonsils can contribute to obstructive sleep apnea by blocking the airway, but they do not cause central sleep apnea, which is related to the brain's control of breathing.
Choice B reason : Obesity is a risk factor for obstructive sleep apnea due to the physical obstruction of the airway, not central sleep apnea, which involves a failure of the brain's signaling to the muscles that control breathing.
Choice C reason : Opioid overdose can depress the central nervous system, including the brain's ability to signal for breath, leading to central sleep apnea.
Choice D reason : A deviated septum can cause difficulty breathing through the nose and contribute to obstructive sleep apnea, but it does not cause central sleep apnea.

Correct Answer is A
Explanation
Choice A reason : Drinking caffeinated beverages in the evening.Caffeine is a stimulant that can significantly disrupt the sleep-wake cycle. Consuming caffeinated beverages in the evening can lead to difficulty initiating sleep because caffeine blocks the action of adenosine, a chemical that promotes sleep. The effects of caffeine can last several hours, thus affecting the quality and duration of sleep.
Choice B reason : Emotional stress activates the body's stress response, causing the release of hormones like cortisol, which increases alertness and can delay the onset of sleep. Chronic stress can lead to a hyperarousal state, making it difficult to fall asleep and stay asleep.
Choice C reason : Bright light.Exposure to bright light, especially blue light from screens, can interfere with the production of melatonin, the hormone that signals the body to prepare for sleep. This can shift the circadian rhythm and disrupt the sleep-wake cycle, making it harder to fall asleep at the usual time.
Choice D reason : A short nap during the day, typically 20-30 minutes, can be beneficial and usually does not interfere with nighttime sleep. However, longer or later naps can make it more difficult to fall asleep at night.
Correct Answer is D
Explanation
The correct answer is D. Wash the client’s body. This is a standard part of postmortem care to ensure the body is clean and presentable for the family and any further procedures.
Choice A reason:
Remove the client’s dentures. This statement is incorrect because dentures should be left in place to maintain the shape of the face and ensure a natural appearance for viewing by the family.
Choice B reason:
Increase the lights in the client’s room. This statement is incorrect because dim lighting is often preferred to create a calm and respectful environment for the family.
Choice C reason:
Place the head of the client’s bed flat. This statement is incorrect because the head should be elevated to prevent discoloration and pooling of blood.
Choice D reason:
Wash the client’s body. This is correct as it is a standard part of postmortem care to ensure the body is clean and presentable for the family and any further procedures.
