Question

Quizplus · Accepted Answer

The symptoms indicate that Casey most likely developed hyponatremia, which is caused by an imbalance of electrolytes in the body due to drinking too much water without replenishing sodium. This can lead to headaches, confusion, and nausea. Dehydration could also cause similar symptoms, but considering they were on a hike, it's possible they were drinking enough water. The flu and food poisoning typically have additional symptoms such as fever, body aches, and gastrointestinal issues. Contaminated water could lead to a variety of illnesses, but the specific symptoms suggest hyponatremia.
