Question

question 31 (1 point)
for marathon runners, drinking plain water without replacing electrolytes increases
the risk for
a) plantar fasciitis.
b) dehydration.
c) heat exhaustion.
d) hyponatremia.

Explanation:

• Plantar fasciitis: It is an inflammation of the plantar fascia (connective tissue on the sole of the foot), usually caused by overuse or improper footwear, not related to electrolyte - water imbalance.
• Dehydration: Occurs when there is a net loss of body water. But if a marathon runner only drinks plain water (without electrolytes), the body's sodium concentration (a key electrolyte) can be diluted.
• Heat exhaustion: A heat - related illness due to prolonged exposure to heat, often with symptoms like heavy sweating, weakness. While dehydration can contribute to heat exhaustion, the key here is the electrolyte - water balance.
• Hyponatremia: This is a low - sodium concentration in the blood. When a runner drinks a large amount of plain water (without replacing electrolytes like sodium) during a marathon (where they may have lost some sodium through sweat), the sodium in the body is diluted, increasing the risk of hyponatremia.

Answer:

D. hyponatremia
