A nurse is conducting an assessment with a client who has been experiencing difficulty adjusting to different time zones due to frequent travel. Which aspect of sleep and wakefulness disorders is the client likely experiencing?

Choice A rationale:

Sleep deprivation has been extensively studied and is known to have significant negative effects on cognitive function. Reduced attention span and memory are some of the primary impacts of sleep deprivation. Sleep is essential for consolidating memories and maintaining optimal cognitive performance. Lack of sleep impairs the brain's ability to focus, process information, and recall memories effectively.

Choice B rationale:

Enhanced immune function is not a potential impact of sleep deprivation. In fact, sleep deprivation can weaken the immune system, making the body more susceptible to infections and illnesses. During deep sleep, the immune system releases cytokines and other protective compounds to combat inflammation and infections. Sleep deprivation disrupts this process, leading to immune system dysfunction.

Choice C rationale:

Altered mood and behavior is a correct potential impact of sleep deprivation. Sleep plays a crucial role in regulating mood and emotional well-being. Sleep-deprived individuals are more likely to experience mood swings, irritability, anxiety, and even depression. The brain's ability to regulate emotions is compromised due to inadequate sleep.

Choice D rationale:

Increased sexual function is not a potential impact of sleep deprivation. In fact, sleep deprivation can lead to decreased sexual desire and function. Hormonal imbalances caused by lack of sleep can negatively affect reproductive health and sexual performance.

Choice E rationale:

Impaired judgment and decision-making is a correct potential impact of sleep deprivation. Sleep-deprived individuals often struggle with making sound judgments and decisions. The prefrontal cortex, responsible for higher-order cognitive functions, is particularly affected by sleep loss. This can result in poor decision-making, impulsivity, and decreased ability to assess risks accurately.

Choice A rationale:

Excessive daytime sleepiness is a symptom that can occur in various sleep disorders, such as sleep apnea, narcolepsy, and even insufficient sleep due to poor sleep hygiene. However, the client's difficulty adjusting to different time zones due to frequent travel is more indicative of a disruption in circadian rhythms caused by shift work and jet lag, rather than a specific disorder characterized by excessive daytime sleepiness.

Choice B rationale:

Shift work sleep disorder is the correct choice. Frequent travel across different time zones disrupts the body's natural circadian rhythm, leading to difficulties in adjusting to new sleep-wake schedules. This disruption can result in insomnia, fatigue, and daytime sleepiness. The client's experience aligns with the characteristics of shift work sleep disorder, which is common among individuals who work irregular hours or travel frequently.

Choice C rationale:

Restless legs syndrome (RLS) involves uncomfortable sensations in the legs that lead to an urge to move them. This disorder is unlikely to be the cause of the client's difficulty adjusting to time zone changes and frequent travel. RLS symptoms are more related to sensations in the legs rather than disturbances in sleep-wake schedules.

Choice D rationale:

Mood disorders, such as depression and anxiety, can certainly impact sleep and wakefulness. However, the client's symptoms of struggling with time zone adjustments and frequent travel are more closely associated with disruptions in circadian rhythms due to changes in sleep schedules rather than being solely indicative of a mood disorder.
