Red Cross Lifeguard Practice Test

When a lifeguard notices signs of dehydration in a patron, the appropriate response is to inform the patron to drink water and rest. This action is crucial because dehydration can lead to serious health issues, including heat exhaustion or heat stroke, especially in a pool or beach environment where patrons may be exposed to heat for extended periods. Encouraging the patron to hydrate helps to replenish fluids lost through sweat and prevent further complications. Advising them to take a break allows their body to recover and reduces the risk of collapse or fainting, which could pose additional dangers not just for the dehydrated individual but also for others in the vicinity. Monitoring the situation continuously while providing this guidance is essential, but taking proactive measures like hydration and rest is the best immediate response to signs of dehydration.
