Question 1 of 5
What is the most likely reason for a hospitalized adult client who routinely works from midnight until 8 a.m. to have a temperature of 99.1°F at 4 a.m.?
Correct Answer: D
Rationale: The correct answer is 'circadian rhythm.' Circadian rhythms are biological cycles that last about 24 hours. The sleep-wake cycle is closely tied to circadian rhythms, affecting body temperature. Normally, core body temperature drops during sleep, reaching its 24-hour low around 4 a.m. In this case, the client's temperature of 99.1°F at 4 a.m. is likely due to the disruption of their circadian rhythm caused by working from midnight until 8 a.m.
Choices A, B, and C are incorrect because delta sleep, slow brain waves, and pneumonia do not directly explain the temperature fluctuation based on circadian rhythm.
