Which of the following actions should be taken if a child is struggling in the water?

Throwing a flotation device to a child struggling in the water is an immediate and effective action that can provide them with much-needed support. The flotation device can help keep the child afloat, allowing them to conserve energy while they make their way to safety or wait for assistance. This method also enables the rescuer to remain at a safe distance, reducing the risk of further complications that can arise from jumping into the water or creating a chaotic situation.

In contrast, jumping in to rescue the child can put both the rescuer and the child at risk, especially if the rescuer is not trained in water rescue techniques. Observing while signaling for help, although important, may delay providing immediate assistance that the child needs. Calling emergency services is a critical action, but it is often better suited for situations where immediate danger exists, or if a rescue cannot be performed safely. Therefore, utilizing a flotation device not only enhances safety but also optimizes the chances of a successful rescue.
