How often should vital signs be monitored during heat injury treatment?

• A. Every 5 minutes.
• B. Every 30 minutes.
• C. Every hour.
• D. Only at the start.

Answer: (A)

Vital signs can change rapidly during heat injury treatment, so you need to watch the patient closely and frequently. Checking them every 5 minutes lets you detect and respond to sudden shifts in heart rate, blood pressure, breathing, temperature, and mental status as cooling and fluids are given. This rapid feedback helps you adjust cooling rates, hydration, or other interventions before instability progresses. Checking only at the start or at longer intervals increases the risk that developing problems go unnoticed, and waiting 30 minutes or an hour between checks can miss dangerous changes during the critical stabilization phase.
