What should a lifeguard do if a patron refuses medical help after being injured?

When a patron refuses medical help after being injured, documenting the refusal while continuing to monitor their condition is the most appropriate course of action. This approach respects the individual's autonomy while also ensuring they receive ongoing care in case their condition worsens.

Monitoring is crucial because injuries can sometimes have delayed symptoms or complications that may not be immediately apparent. By keeping an eye on the patron, the lifeguard is in a position to act swiftly if the situation changes, ensuring the safety and well-being of the patron.

Documentation serves to create a record of the incident, including the patron’s refusal of help, which is important for liability and communication with other staff members or medical professionals. It ensures that there is clear evidence of the lifeguard's adherence to protocols and the steps taken during the incident, which is important for legal and procedural reasons.

Other options would not provide the same level of care and respect for the patron's wishes. Ignoring the patron's refusal could lead to legal complications or exacerbate the situation, while calling authorities may not be necessary and could lead to further distress for the patron. Delivering aid despite refusal disregards the patron's autonomy and could cause additional injury or emotional harm.
