What actions should be taken to prevent heat loss from a hypothermic diver?

To effectively prevent heat loss from a hypothermic diver, a comprehensive approach addressing multiple factors is essential, which makes the choice encompassing all of the suggested actions the correct one.

Removing all wet items is critical, as wet clothing significantly accelerates heat loss through conduction. When exposed to water, especially in cold environments, a diver's body loses heat much faster than in air. By removing these wet items, the diver retains more body heat and can start to warm up more effectively.

Administering warm clear liquids helps raise the internal body temperature. Hydration is vital in a hypothermia scenario, as the body uses fluids to maintain temperature and facilitate physiological processes. Warm fluids will not only help to hydrate the diver but also provide a source of warmth from the inside.

Placing the diver out of direct wind but in the sun can enhance their warming process. Wind can exacerbate heat loss through convection, so finding shelter from the wind minimizes this risk. Additionally, sunlight can provide a natural source of warmth, helping to raise the diver's body temperature.

Integrating all these strategies creates a multi-faceted approach that addresses the mechanisms of heat loss effectively, making the choice that includes all of them the best option.
