Which statement best describes room temperature water misting cooling?

• A. Administer IV fluids
• B. Move pt to a cool, shady place; Remove clothing and wet patient; Fan skin
• C. Immersion in ice water
• D. Apply ice packs to head

Answer: (B)

Evaporative cooling is at work here: wetting the skin and moving air across it increases evaporation, which draws heat away from the body. Moving the patient to a cooler, shaded area reduces the surrounding heat load; removing clothing exposes more skin for heat transfer; and fanning or having air move over the wet skin speeds evaporation and heat loss. Room-temperature misting relies on evaporation rather than cold contact, making it effective and practical in many field settings. Other methods either don’t provide as much whole-body cooling (like applying ice packs to the head, which targets a small area), or involve rapid cooling approaches that are less practical or carry more risk in a non-controlled environment (ice water immersion can be faster but is harder to implement safely; IV fluids treat hydration but don’t directly cool the body). So the described steps best illustrate how room-temperature misting cooling works.
