What should a lifeguard do if they suspect a swimmer is in distress?

When a lifeguard suspects a swimmer is in distress, the appropriate response is to watch closely and prepare to intervene. This option allows the lifeguard to assess the situation without putting themselves or the swimmer at additional risk. By observing the swimmer’s behavior and condition, the lifeguard can determine the best course of action—not only to ensure the swimmer’s safety but also to maintain their own safety and that of other swimmers in the area.

This approach allows the lifeguard to wait for clear signs of distress or further confirmation that an intervention is necessary, which can help to avoid unnecessary rescues or panic. Preparation to act ensures that the lifeguard is ready to take the appropriate steps quickly if the situation escalates or if the swimmer fails to signal for help.

Other options, such as ignoring the situation until there is a clear signal for help, could lead to a worsening of the swimmer's condition. Jumping in without a plan may be reckless and potentially place the rescuer in danger. Simply instructing a distressed swimmer to swim back to the edge assumes that they are physically capable of doing so, which may not be the case; many distressed swimmers may struggle to follow commands.
