Question 1

A skier is found unresponsive in a snow pit with a core temperature of 28°C (82°F). Which rewarming method is most appropriate in the field?

Accepted Answer

Active external rewarming with hot packs to axillae and groin

Answer

For severe hypothermia, apply chemical heat packs to high-heat-transfer areas (axillae, groin, neck) while preventing afterdrop and handling the patient gently.

Question 2

Which lightning strike pattern occurs when current travels along the ground and enters a victim through one foot and exits the other?

Accepted Answer

Ground current

Answer

Ground current (step potential) is the most common cause of lightning injury and affects multiple victims standing near a strike point.

Question 3

A hiker presents with red, painful blisters on the dorsum of the foot after a long descent in tight boots. This presentation is consistent with:

Accepted Answer

Superficial frostbite

Answer

Superficial frostbite causes red, painful skin with blister formation upon rewarming, typically affecting exposed or constricted extremities.

Question 4

During a river rescue, a rescuer enters the water. Which self-rescue position should be assumed when swimming in fast-moving water?

Accepted Answer

On the back, feet downstream, toes up

Answer

The defensive swimming position (on back, feet downstream, toes up) allows the swimmer to fend off rocks and stay afloat while moving toward shore.

Question 5

Avalanche victims buried for more than 35 minutes without an air pocket have significantly reduced survival due primarily to:

Accepted Answer

Asphyxiation from CO2 buildup and oxygen depletion

Answer

The primary cause of death in buried avalanche victims is asphyxiation; CO2 rebreathing and hypoxia occur rapidly without an air pocket.
