New York State Basic Emergency Medical Technician (EMT-B) Practice Exam

In case of a burn, what should an EMT do if blisters are present?

1. Puncture the blisters for drainage

2. Leave the blisters intact to protect the skin

3. Apply ointment to the blisters

4. Cover the area with ice to relieve pain

The correct answer is: Leave the blisters intact to protect the skin

In the case of burns where blisters are present, leaving the blisters intact serves an important purpose in the healing process. Blisters act as a natural protective barrier, shielding the underlying tissue from infection and further injury. This protection is crucial because the skin plays a vital role in the body's defense system. By keeping the blisters closed, the body can facilitate healing more effectively, allowing for natural regeneration of the skin without additional complications. Puncturing the blisters can introduce pathogens and increase the risk of infection, while applying ointments directly to open blisters can irritate the area and hinder healing. Covering the area with ice is not recommended because it can further damage the skin and underlying tissues and does not address the need for protection that blisters provide. Therefore, by leaving the blisters intact, EMTs support the body’s natural healing mechanisms while minimizing the risk of infection and further complications.
