If a coworker has collapsed while lifeguarding and shows signs of altered mental status, what is the best response?

The best response in a situation where a coworker has collapsed and exhibits signs of altered mental status is to focus on rapidly cooling the body. This approach addresses the critical need to lower the body temperature, especially if the collapse is suspected to be due to heat exhaustion or heat stroke. Aggressive cooling methods such as pouring water, fanning, and applying ice packs are effective in swiftly reducing a dangerously high body temperature, which can help prevent further complications or even death.

In the context of emergency response, treating the person for possible heat-related illnesses is essential, given the immediate risks associated with altered mental status. Moreover, neglecting to monitor vital signs or leave the individual alone can lead to worsening conditions, while offering cold fluids may be helpful in certain situations but is less effective than direct physical cooling in preventing a serious outcome.

Overall, a proactive approach that prioritizes cooling the individual is crucial in this emergency scenario.
