Which of the following actions is crucial for a lifeguard when assessing a victim?

Maintaining a calm demeanor while evaluating the situation is crucial for a lifeguard when assessing a victim. This approach ensures that the lifeguard can think clearly and make informed decisions in a potentially chaotic environment. A calm lifeguard can effectively assess the victim's condition, communicate with team members, and provide the appropriate care without exacerbating the situation.

Rushing to get the victim out of the water could lead to further injury, particularly if the lifeguard has not fully assessed the victim's state. Simply checking for visible injuries does not provide a complete view of the victim's condition, as many injuries may not be immediately apparent. Additionally, asking bystanders for their opinions can lead to confusion and misinformation, diverting attention away from the critical assessment and care of the victim. Keeping a calm demeanor allows the lifeguard to prioritize the victim's needs and ensure the best possible outcome.
