Cody and Casey Are Friends Who Enjoy Working Out Together

question 36

Multiple Choice

Cody and Casey are friends who enjoy working out together. Both are 25 years old. They enjoy going on hikes, running, and biking. During their last adventure, they traveled to the Rocky Mountains for a two-day hiking trip. During the first day of their journey, Cody made sure to keep drinking water and refuel with healthy snacks throughout the day. Casey, who was less diligent in drinking and refueling, slowed the hiking pace, got a severe muscle cramp in her calf, and felt dizzy shortly before they made it to camp. After a little break, she and Cody were able to make it to camp. That night, Cody and Casey ate well and relaxed. After dinner, Cody drank three beers by the campfire before going to sleep. After a good night's sleep and a healthy breakfast of fruit, peanut butter sandwiches, and coffee, they set out on their second day of hiking. In an attempt to avoid the fatigue and muscle cramps she experienced during day one of the hike, Casey made sure to drink about two cups of water every 10-15 minutes, even though she was not thirsty, to avoid becoming dehydrated. Cody was confident that he would be able to stay hydrated and fueled based on his success on day one. However, he noticed that he was extremely thirsty early in the hike and had to drink more water than he did on day one. Several hours into the hike, Casey started to feel a headache coming on and thus she increased her water intake. A short while later, she had to stop hiking because she became confused, felt nauseated, and began to vomit. Cody called the park rangers to get her some medical attention.
On day two of the hike, why did Casey most likely develop a headache and experience confusion and nausea?
