What is the recommended action if a swimmer shows signs of distress?

When a swimmer shows signs of distress, the recommended action is to assist them with a flotation device. Providing a flotation device offers immediate support and stability, allowing the swimmer to stay afloat and reducing the risk of drowning while help is being organized. This method ensures the swimmer has a way to remain safe and can aid in their recovery as assistance arrives.

Using a flotation device helps to alleviate panic and can also prevent the swimmer from expending excessive energy while they are in distress. This approach is particularly crucial in emergency situations, where quick thinking and immediate intervention can save a life.

The other options do not address the swimmer's immediate needs effectively. Encouraging them to continue swimming may lead to exhaustion or further distress. Calling for help immediately is necessary but should ideally be done in conjunction with providing assistance, ensuring the distressed swimmer has a tool to regain their composure. Ignoring the situation is never advisable, as it can lead to dire consequences if the swimmer cannot call for help themselves.
