Final answer:
Possible causes for the woman's symptoms include jet lag, insufficient sleep, and narcolepsy.
Step-by-step explanation:
The 30-year-old woman's symptoms of trouble staying awake at work, difficulty getting out of bed, and confusion in the morning may be due to a few factors. One possibility is the disruption of her circadian clock, which could be caused by traveling across multiple time zones and experiencing jet lag. Another factor could be insufficient sleep, which can result in fatigue, decreased alertness, and impaired cognitive function. Additionally, narcolepsy, a sleep disorder characterized by excessive sleepiness and sudden episodes of sleep, could also be a potential cause.
