Which of the following actions displays a lifeguard's preparedness?

A lifeguard's preparedness is fundamentally about being equipped and ready to respond to any situation that may arise in an aquatic environment. Having essential items ready, such as sun protection, demonstrates a proactive approach to safety and health. This ensures not only the lifeguard's well-being but also promotes a safe environment for patrons who are likely exposed to the sun for extended periods.

Preparedness also involves having the necessary equipment at hand to address potential hazards or emergencies effectively. This readiness enhances the overall safety of the swimming area and shows a commitment to providing a safe experience for all patrons.

The other choices, while they may involve engaging with patrons or relying on others, do not illustrate the same level of personal responsibility and preparedness critical for a lifeguard's role. Being equipped and ready for emergencies is paramount, and the act of having important items like sun protection readily available clearly reflects a lifeguard's serious commitment to their responsibilities.
