What term describes work scheduled during swing or night shifts?

• A. Detoxification
• B. Opioids
• C. shift work
• D. REM sleep

Answer: (C)

Shift work describes work schedules that fall outside ordinary daytime hours, including evening, night, or rotating shifts. This term directly captures the idea of when someone is scheduled to work, not what they're doing or their health condition. Detoxification refers to removing toxins, opioids are a class of drugs, and REM sleep is a sleep stage; none of these relate to the scheduling aspect. So shift work is the best fit because it specifically addresses the timing of work.
