Prewarming a prep solution in a microwave or uncontrolled or unmonitored systems creates a risk of:

• A. Allergies
• B. Chemical burn
• C. Fire
• D. Thermal burn

Answer: (D)

Prewarming a prep solution can raise its temperature enough that, when the liquid contacts skin, heat is transferred into tissue and causes injury. Microwaving can create uneven heating with hot spots, and unmonitored systems lack regulation to prevent overheating, so the risk is tissue damage from heat—thermal burn. Allergic reactions aren’t caused by heating, and chemical burns come from caustic chemicals acting on tissue, not from heat alone. Fire is possible with flammable solvents, but the immediate patient hazard during skin preparation is the thermal burn from contact with overheated liquid.
