What should a lifeguard do first when faced with an allergic reaction?

In the context of an allergic reaction, the immediate priority for a lifeguard is to identify the allergen. Understanding what the individual is reacting to is crucial as it helps to assess the severity of the reaction and determine the appropriate response. Identifying the allergen enables the lifeguard to take specific actions, such as removing the person from exposure to the allergen if possible or informing emergency services about the allergen, which is critical for effective treatment.

Once the allergen is identified, appropriate interventions, including administering medication such as antihistamines or an epinephrine auto-injector, can follow based on the established protocols and the severity of the reaction. Monitoring the patient is also important, but it should occur after identifying the allergen, as understanding the cause will influence how to monitor and manage the situation. Contacting a family member is not an immediate priority in the face of an allergic reaction; the focus should be on addressing the immediate medical needs of the individual experiencing the reaction.
