What can happen if a correctional officer deviates from their sleep schedule?

• A. It can cause increased energy and alertness.
• B. It can make it more difficult to adjust back to the work schedule.
• C. It has no effect on shift readiness.
• D. It improves reaction time immediately.

Answer: (B)

Deviating from a sleep schedule disrupts your circadian rhythm and sleep regulation. When you don’t sleep at times your body expects, your internal clock becomes desynchronized from the work schedule, making it harder to re‑entrain once you return to duty. This leads to lingering fatigue, reduced alertness, and slower reaction times, all of which affect shift readiness. The statement that it makes it more difficult to adjust back to the work schedule best captures this real consequence of circadian misalignment.

The other ideas imply benefits or no effect, which doesn’t align with how disrupted sleep typically impacts performance and re‑entry to a fixed shift.
