Question

which of the following may contribute to hyponatremia?
check all that apply
eating too many salty foods at one time
severe diarrhea
drinking too much plain water while running an ultra - endurance event
severe vomiting

Explanation:

• Eating too many salty foods at one time: This would increase sodium levels, not cause hyponatremia.
• Severe diarrhea: Causes loss of sodium - rich fluids. If not replaced properly (e.g., only replacing water), it can lead to hyponatremia.
• Drinking too much plain water while running an ultra - endurance event: Dilutes the sodium in the body (dilutional hyponatremia).
• Severe vomiting: Similar to diarrhea, causes loss of sodium - containing fluids. If only water is replaced, sodium levels can drop.

Answer:

Severe diarrhea, Drinking too much plain water while running an ultra - endurance event, Severe vomiting.
