A nurse cares for these four patients. Which patient has the highest risk for problems with sleep physiology?

A) Retiree who volunteers twice a week at Habitat for Humanity
B) Corporate accountant who travels frequently
C) Parent with three teenagers
D) Lawn care worker

The corporate accountant is likely to work long hours and have significant stress associated with work demands. Compounded by travel, these factors are likely to precipitate unstable sleep patterns and inadequate sleep time. The retiree and lawn care worker engage in physical activity during the day, which will promote natural fatigue and sleep. The parent's sleep is unlikely to be disturbed; teenagers sleep through the night.
