A nurse is assisting with teaching a client about the sleep-wake cycle. The nurse should include that which of the following factors can interfere with the sleep-wake cycle?
Drinking caffeinated beverages in the evening
Emotional stress
Bright light
A 20-minute nap during the day
The Correct Answer is A
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
Choice A reason : Change in marital status.A change in marital status is considered a social stressor rather than a physiological one. It relates to the personal and emotional aspects of one's life, impacting mental and emotional well-being rather than directly causing a physiological response.
Choice B reason : Financial difficulties.Financial difficulties are categorized as social stressors. They can lead to significant stress but do not directly cause a physiological response. Instead, they can indirectly affect health over time through sustained stress.
Choice C reason : Academic pressure.Academic pressure is a psychological stressor. It involves cognitive and emotional challenges that can lead to stress but is not a direct physiological stressor.
Choice D reason : Burn injury.A burn injury is a physiological stressor. It causes an immediate physical response in the body, triggering pain receptors, inflammatory responses, and the need for physical healing processes.
