A client is undergoing a sleep study to aid in the diagnosis of a sleep disorder. The study monitors various physiological parameters during sleep, including brain waves, eye movements, muscle activity, and heart rate. Which type of test is the client undergoing?

Actigraphy.

Maintenance of wakefulness test (MWT).

Polysomnography (PSG).

Epworth sleepiness scale.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Actigraphy is a method that involves wearing a wrist-worn device that monitors movement and light exposure to infer sleep patterns and circadian rhythms. It's often used in sleep research and can provide long-term data, but it doesn't directly measure physiological parameters like brain waves, eye movements, and heart rate. Therefore, it's not the correct choice for this scenario.

Choice B rationale:

The Maintenance of Wakefulness Test (MWT) is used to assess a person's ability to stay awake during a quiet, daytime environment. It's typically used to evaluate excessive daytime sleepiness, especially in individuals with conditions like narcolepsy. This test doesn't involve monitoring physiological parameters during sleep and is performed while the person is awake, so it's not the correct choice.

Choice C rationale:

Polysomnography (PSG) is the correct choice. PSG is a comprehensive sleep study that involves monitoring various physiological parameters during sleep, including brain waves (electroencephalogram, EEG), eye movements (electrooculogram, EOG), muscle activity (electromyogram, EMG), and heart rate (electrocardiogram, ECG). This test is commonly used to diagnose sleep disorders such as sleep apnea, insomnia, and parasomnias.

Choice D rationale:

The Epworth Sleepiness Scale is a self-report questionnaire used to assess an individual's likelihood of falling asleep in various situations. It's a subjective measure of daytime sleepiness and doesn't involve monitoring physiological parameters during sleep, so it's not the correct choice.

Correct Answer is ["C","D","E"]

Explanation

Choice A rationale:

Enhanced mood and behavior. Enhanced mood and behavior are not potential consequences of sleep deprivation. Instead, sleep deprivation is often linked to mood disturbances such as irritability, mood swings, and increased stress. Lack of sleep can negatively impact emotional well-being and behavior.

Choice B rationale:

Improved communication skills. Improved communication skills are not a potential consequence of sleep deprivation. Sleep deprivation impairs cognitive functions, including communication skills. Individuals who are sleep-deprived may experience difficulties in articulating thoughts, concentrating, and engaging in effective communication.

Choice C rationale:

Reduced work performance. This is one of the correct answers. Sleep deprivation can significantly reduce work performance. Cognitive deficits resulting from lack of sleep can lead to decreased productivity, poor decision-making, and impaired concentration. This can have a negative impact on work-related tasks and responsibilities.

Choice D rationale:

Increased appetite regulation. This is another correct answer. Sleep deprivation can disrupt the body's appetite regulation mechanisms. It leads to hormonal changes that increase the production of ghrelin, a hormone that stimulates appetite, and decrease the production of leptin, a hormone that signals satiety. As a result, sleep-deprived individuals often experience increased hunger and cravings.

Choice E rationale:

Altered hormonal levels. This is the third correct answer. Sleep deprivation can disrupt the normal balance of hormones in the body. It can lead to changes in hormones such as cortisol (the stress hormone) and growth hormone. These hormonal disruptions can have widespread effects on various physiological processes, including metabolism, stress response, and immune function.

A. Reduced attention span and memory. B. Enhanced immune function. C. Altered mood and behavior. D. Increased sexual function. E. Impaired judgment and decision-making.

Correct Answer is ["A"]

Explanation

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.
