Circadian rhythms are the body's internal biological clock that regulate various physiological processes such as sleep-wake cycles, hormone secretion, and body temperature. These rhythms repeat approximately every 24 hours and are influenced by external cues such as light and activity. Therefore, the regularity in the student nurse's blood pressure and body temperature readings on a daily basis is likely due to circadian rhythms. The other choices (A, C, and D) are not supported by scientific evidence.
