question 38 (1 point)
two hours in to a six - hour hike on a cool fall day, it begins to rain. helena has no rain jacket or poncho, and is wearing only lightweight clothing. helena is at increased risk for
a) hyperthermia.
b) hypothermia.
c) water intoxication.
d) frostbite.

Explanation:

• Hyperthermia: It is an abnormally high body temperature due to failed thermoregulation. But in this case, the weather is cool and it's raining, so the body is losing heat rather than overheating.
• Hypothermia: Occurs when the body loses heat faster than it can produce it, leading to a dangerously low body temperature. Helena is in a cool environment, wearing lightweight clothing, and it's raining (which can accelerate heat loss as water conducts heat away from the body).
• Water intoxication: Also known as hyponatremia, it occurs when there is too much water in the body relative to sodium levels. There is no indication that Helena is consuming excessive water.
• Frostbite: Is tissue damage caused by freezing. The scenario mentions a cool fall day, not a freezing environment.

Answer:

B. hypothermia
