Which of the following is a symptom of fatigue?

• A. Slow reaction, poor judgment, reduced awareness, and decreased performance.
• B. Increased energy and alertness.
• C. Mild headaches only.
• D. No changes in performance.

Answer: (A)

Fatigue commonly reduces cognitive and motor performance, manifesting as slower reaction times, poorer judgment, reduced situational awareness, and overall decreased performance. This reflects how tiredness drains attention and processing speed, leading to decisions and actions that are not as accurate or timely as when rested.

The option that lists these exact symptoms best describes fatigue, which is why it is the correct choice. Increased energy and alertness would indicate the opposite of fatigue. Mild headaches can occur but do not by themselves capture the full impact on performance. No changes in performance would suggest no fatigue at all.
