What should a lifeguard do if they notice a swimmer showing signs of hypothermia?

When a lifeguard notices a swimmer showing signs of hypothermia, it is crucial to remove the person from the water as the first step. This action prevents further heat loss, as exposure to cold water exacerbates the hypothermic condition. Covering the individual is important to trap body heat and provide warmth; using blankets or dry clothing can help in this recovery process.

Seeking medical help if necessary is essential because hypothermia can lead to serious health complications if not treated properly. Medical professionals can provide advanced care that may be needed depending on the severity of the hypothermia. The approach outlined ensures the immediate safety and well-being of the affected swimmer while facilitating the best chance for recovery.

In contrast, the other options do not adequately address the urgent need to prevent further heat loss or provide appropriate care. Encouraging a person to swim faster could lead to exhaustion or an increased risk of drowning. Administering first aid on the spot without removing them from the cold environment is likely to be ineffective since the most pressing concern is to prevent additional heat loss. Lastly, waiting for the signs to become more severe is dangerous and could lead to a life-threatening situation, as timely intervention is critical in cases of hypothermia.
