Which description best matches over-exertion concerns?

• A. Dehydration symptoms
• B. Heat stroke symptoms
• C. Hyponatremia symptoms
• D. Over-exertion concerns

Answer: (D)

Over-exertion concerns describe the warning signs that appear when someone pushes beyond safe exercise limits. These concerns span a range of possible issues that can arise from intense activity, including dehydration signs, heat-related illness signs, or electrolyte problems like hyponatremia. The key point is to recognize that the phrase itself captures the broad issue of overexertion, rather than naming one specific problem. The other options point to particular conditions that can result from overexertion, but they don’t convey the overall concern as a general category. In practice, look for a combination of cues—feeling lightheaded, dizziness, extreme fatigue, confusion, rapid heartbeat, heavy sweating, or poor skin color—and respond with rest, fluids, cooling, and medical help if severe symptoms appear.
