The nurse wants to assess for disturbances in circadian rhythms in a patient admitted for major depressive disorder. Which question best implements this assessment?

A) "Do you ever see or hear things that others do not?"
B) "Do you have problems with short-term memory?"
C) "What are your worst and best times of day?"
D) "How would you describe your thinking?"

Mood changes throughout the day are related to circadian rhythms. Questions about sleep pattern would also be relevant to circadian rhythms. The question about seeing or hearing things is relevant to the assessment for illusions and hallucinations. The question about thinking is relevant to the assessment of thought processes. The other question is relevant to assessment of memory.
