Cody and Cassy are friends who enjoy working out together. 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 refueling with health snacks throughout the day. Cassy, who was less diligent in drinking and refueling, had to slow
down the hiking pace and got a severe muscle cramp in her calf 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 Cassy ate well and relaxed. After dinner Cody drank three beers by the campfire before going to sleep. After a good night's rest 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, Cassy made sure to drink water every 10-15 minutes. Cody was confident that he would be able to stay hydrated and fueled based on his success from 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 Cassy started to feel a headache coming on so 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 medical attention. On day two of the hike, what is the likely reason Cassy developed a headache, confusion, and nausea? A) She was experiencing dehydration. B) She was experiencing the onset of the flu. C) She was experiencing water intoxication. D) She was experiencing food poisoning from the peanut butter sandwich.
