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.
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.

Related Questions
Correct Answer is A
Explanation
Choice A rationale:
Vivid dreams can be associated with certain sleep disorders such as REM sleep behavior disorder, where individuals act out their dreams due to a lack of muscle paralysis during REM sleep. This can lead to physical movements during sleep and potentially result in injuries to the individual or their sleep partner.
Choice B rationale:
Hair thinning is not typically a symptom of sleep and wakefulness disorders. It is more commonly associated with factors like genetics, hormonal changes, and certain medical conditions such as alopecia.
Choice C rationale:
Feeling very energetic during the daytime is not aligned with the symptoms of sleep and wakefulness disorders. Sleep disorders often lead to daytime fatigue and excessive sleepiness rather than increased energy levels.
Choice D rationale:
Experiencing muscle spasms at night is not a classic symptom of sleep and wakefulness disorders. Muscle spasms could be related to various factors such as electrolyte imbalances, restless legs syndrome, or nocturnal leg cramps, but they are not among the primary symptoms of these disorders.
Correct Answer is C
Explanation
Choice A rationale:
Increased irritability and anxiety are indeed potential impacts of sleep deprivation, but they primarily affect the emotional aspect of the individual rather than cognitive function.
Choice B rationale:
Altered metabolic function such as obesity is a potential impact of sleep deprivation, but it's related to metabolic processes rather than cognitive function.
Choice C rationale:
Impaired judgment and decision-making are well-documented effects of sleep deprivation. Sleep plays a crucial role in cognitive processes, and lack of adequate sleep can lead to difficulties in reasoning, problem-solving, and making sound decisions.
Choice D rationale:
Decreased sexual function like low libido is a potential impact of sleep deprivation, but it's related to sexual health rather than cognitive function.
