Which factor is considered when determining a diver's medical fitness before a dive?

• A. Age and height.
• B. Hair color.
• C. Medical fitness evaluation; factors include cardiovascular/respiratory health and fit-to-dive assessments.
• D. Diving experience.

Answer: (C)

Medical fitness evaluation is the factor used to determine if a diver is medically safe to dive. This focuses on how well the cardiovascular and respiratory systems function and whether the diver is fit to handle the demands of diving, including immersion, exertion, and pressure changes. The evaluation typically includes medical history, a physical exam, and may involve tests such as ECG or lung function tests to assess fit-to-dive.

Age, height, hair color, or diving experience do not directly determine medical fitness for diving. Age or other physical traits aren’t themselves the deciding factor, and while experience affects skills and training, it doesn’t replace a medical clearance.
