During the day Mr. Johnson is constantly tired. Mr. Johnson is probably suffering from _____________ . a. insomnia b. sleep terrors c. narcolepsy d. obstructive sleep apnea (OSA)

Short Answer

Expert verified
(d) obstructive sleep apnea (OSA)

Step by step solution

01

Insomnia

Insomnia is a sleep disorder characterized by difficulty in falling asleep, staying asleep, or both, leading to insufficient sleep. While Mr. Johnson does feel tired during the day, which could be a result of inadequate sleep, there is no mention of him having difficulty falling or staying asleep. Therefore, the answer is not (a) insomnia.
02

Sleep Terrors

Sleep terrors, also known as night terrors, are episodes of screaming, intense fear, and flailing during sleep, mostly occurring in children. The given symptoms do not match this description, ruling out (b) sleep terrors as the correct answer.
03

Narcolepsy

Narcolepsy is a neurological disorder that affects the control of sleep and wakefulness, causing excessive daytime sleepiness, sudden loss of muscle tone, and short, uncontrollable episodes of sleep throughout the day. While Mr. Johnson does experience daytime fatigue, the other symptoms mentioned are not consistent with narcolepsy. This eliminates (c) narcolepsy as the answer.
04

Obstructive Sleep Apnea (OSA)

Obstructive sleep apnea (OSA) is a common sleep disorder in which a person's breathing is partially or completely obstructed due to the collapse of their airway during sleep. It causes periods of reduced or no breathing, followed by gasping or snorting, leading to loud snoring. OSA can result in reduced oxygen supply to the brain and disrupted sleep, causing the individual to feel constantly tired during the day. The symptoms described for Mr. Johnson match the characteristics of this sleep disorder. Based on the given information and analysis of the different sleep disorders, we can conclude that Mr. Johnson is probably suffering from (d) obstructive sleep apnea (OSA).
