Why is it important for lifeguards to know CPR and first aid?

The importance of lifeguards knowing CPR and first aid lies in their critical role during emergencies. Lifeguards are often the first responders in a situation where someone may be in danger, such as drowning or experiencing a medical emergency. In these instances, having the skills to provide immediate assistance can be life-saving. CPR (cardiopulmonary resuscitation) can help maintain blood flow and breathing for a person who has stopped breathing or whose heart has stopped beating, while first aid enables lifeguards to address a variety of medical issues, from injury management to stabilizing someone until professional medical personnel arrive. This knowledge allows lifeguards to act swiftly and confidently, ultimately improving the chances of a positive outcome in emergency situations.

Other options focus on less critical functions; lifeguards are primarily tasked with ensuring the safety of swimmers, not entertaining them, assessing abilities, or teaching lessons, although these may be part of their broader responsibilities. Nonetheless, the foremost priority during an emergency is to provide life-saving measures.
