Hypothermia Risk on a Winter Day Hike
You are leading a group of 5 on a winter day hike in a hilly area. The temperature is -2°C with a wind chill of -8°C. It is raining lightly, and the trails are muddy. One participant, a 14-year-old, is wearing cotton jeans and a cotton hoodie, and has been shivering for the last 30 minutes. They are sluggish and have trouble speaking clearly. The group has been hiking for 2 hours and is 4 km from the trailhead. You have a first aid kit, extra warm clothing (including a synthetic jacket and fleece), and a group shelter. The participant's parents are not on the trip. What do you do?
1. What signs suggest the participant's condition, and what are the immediate priorities?
Read the worked answer
Signs: shivering, sluggishness, and difficulty speaking suggest mild to moderate hypothermia. Cotton clothing is a risk factor as it loses insulation when wet. Immediate priorities: stop the hike, get the participant out of the wind and rain, remove wet clothing, and replace with warm, dry layers (synthetic jacket, fleece). Provide warm, sweet drinks if the participant is alert and can swallow. Monitor for worsening signs (e.g., cessation of shivering, confusion). If symptoms improve, continue with a shortened, low-intensity route back. If not, call for help. The participant is a minor, so you must also consider duty of care and contact parents as soon as possible.
2. How would you manage the group and the evacuation?

Group management: assign one adult to stay with the affected participant while you organize the rest. Keep the group together for warmth and support. Use the group shelter to block wind. Decide on evacuation: if the participant improves, walk slowly as a group to the trailhead (4 km, but may take 2 hours at a slow pace). If not improving, send two strong members to get help while you stay with the participant. Ensure the participant is insulated from the ground. Monitor continuously. Communicate the situation to the participant's parents and emergency services if needed. Document the incident.
