For superficial wounds, diathermy is generally avoided because it can cause moisture.

• A. It should be used to dry moisture
• B. It should be avoided due to moisture
• C. It is the preferred treatment
• D. It has no effect

Answer: (B)

Diathermy delivers heat through high‑frequency current, raising tissue temperature. For superficial wounds, this heating can increase local moisture by boosting circulation and exudate around the wound, which promotes maceration of the surrounding skin. Macerated skin is more fragile and less able to form a protective barrier, slowing healing and raising infection risk. Because maintaining a relatively dry environment is important for managing superficial wounds, diathermy is generally avoided in these cases. It does not dry moisture or become the preferred treatment, and it certainly has an effect by heating tissue, which can worsen moisture-related issues.
