A nurse is educating a group of clients about sleep-related breathing disorders. Which of the following symptoms is often associated with obstructive sleep apnea (OSA)?

Choice A rationale:

Hypersomnolence refers to excessive daytime sleepiness and an increased need for sleep. It is not characterized by abnormal movements of the limbs or body during sleep. Hypersomnolence can be a symptom of various sleep disorders but is not directly related to the condition described.

Choice B rationale:

Periodic limb movement disorder (PLMD) involves repetitive and involuntary movements of the legs and sometimes the arms during sleep. These movements are distinct from the abnormal movements described in the question. PLMD can cause sleep disturbances and daytime fatigue but is not the disorder characterized by stereotyped movements during sleep.

Choice C rationale:

Sleep-related rhythmic movement disorder (SRMD) is characterized by repetitive or stereotyped movements during sleep or while falling asleep. These movements can include head banging, body rocking, or rolling. SRMD is often seen in children and tends to decrease with age. It is a parasomnia, which is a category of sleep disorders involving unusual behaviors during sleep.

Choice D rationale:

Circadian rhythm sleep-wake disorder involves disruptions in the sleep-wake cycle due to misalignments between a person's internal body clock and external cues like light and darkness. It is not characterized by abnormal movements of the limbs or body during sleep. Circadian rhythm sleep-wake disorder can lead to difficulties falling asleep or staying awake at appropriate times but is distinct from the disorder described.

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.
