What signs suggest hypothermia in a passenger and what immediate steps should you take?

• A. No symptoms; continue.
• B. Sweating and overheating; continue.
• C. Nausea only; rest.
• D. Shivering, confusion, slowed responses; move to a warmer environment, remove wet clothing, cover with blankets, and seek medical aid.

Answer: (D)

Hypothermia happens when the body loses heat faster than it can produce it, causing the core temperature to drop. As heat loss progresses, the person may start with shivering, but can become confused and slow to respond as brain function is affected. Those signs mean urgent action is needed to prevent the situation from worsening. The best response is to move the passenger to a warmer environment, remove wet clothing, and cover them with dry blankets or other insulating layers to trap heat, while arranging medical help as soon as possible. While warming, keep them as comfortable as possible and monitor breathing and responsiveness; if they become unconscious or stop breathing, start appropriate emergency care and call for help. The other options don’t reflect the danger signs of hypothermia and would delay the necessary warming and medical assistance.
