Which description matches fatigue symptoms?

• A. Shortness of breath; chest pain; irregular or rapid heartbeat; dizziness or lightheadedness; severe abdominal, pelvic, or back pain
• B. Coughing and nasal congestion
• C. Dizziness and fainting only
• D. Nausea only

Answer: (A)

Fatigue in a fitness setting is a signal that needs context. When fatigue comes with other serious symptoms—shortness of breath, chest pain, irregular or rapid heartbeat, dizziness or lightheadedness, or severe abdominal, pelvic, or back pain—it suggests a potential medical emergency rather than simple tiredness from exercise. These signs can indicate cardiac, respiratory, or other acute issues, so stopping activity and seeking medical evaluation is the appropriate response.

The other descriptions describe symptoms that are not typically tied to fatigue as a warning sign in this setting: coughing and nasal congestion point more to a mild illness or allergies; dizziness or fainting alone is too narrow a picture; nausea alone is not enough to describe fatigue-related risk.
