In ABCDE, what does 'Exposure/Environmental control' emphasize?

• A. Exposing injuries while preventing hypothermia and protecting patient from elements.
• B. Exposing the patient’s entire body to fresh air only.
• C. Marketing to patient about environment.
• D. Avoiding exposure to electricity.

Answer: (A)

Exposure/Environmental control means both fully inspecting the patient for injuries by exposing only what is necessary and, at the same time, actively preventing harm from the surroundings. You remove or open clothing as needed to assess for hidden injuries, bleeding, burns, or deformities, but you immediately take steps to keep the patient warm and protected from the elements. Keeping the patient warm is crucial because even short exposure can lead to hypothermia, worsen bleeding, or complicate assessment. It also involves shielding the patient from wind, rain, cold, or contamination and managing the environment around them to reduce additional risks.

The other ideas don’t fit because simply exposing the body to fresh air omits the important temperature and environmental protection aspect; marketing to the patient has no place in this clinical step; and avoiding exposure to electricity is a separate safety concern not addressed by this portion of the assessment.
