**Core Concept:** Burn injuries are a type of trauma that affects the skin and underlying tissues due to exposure to heat, chemicals, electricity, or radiation. These injuries can range from superficial to deep and result in varying degrees of tissue damage and potential complications.

**Why the Correct Answer is Right:** The correct answer, **B. Immediate application of ice cold water**, is a recommended treatment for burn injuries. Cooling the affected area with ice helps to reduce pain, inflammation, and tissue damage. It also slows down the healing process and reduces the risk of infection.

**Why Each Wrong Option is Incorrect:**

A. **No bandage to head & neck**: Applying a bandage to the head and neck could cause further injury, as these areas are highly sensitive and require special care. Additionally, excessive pressure from a bandage could lead to compression injuries.

C. **Superficial burns without blister- no need of dressing**: In some cases, superficial burns may not require dressing, but it is generally recommended to apply a moist dressing to all burns to maintain a moist environment and facilitate healing.

D. **Escarotomy done for peripheral circumscribed lesions**: Escarotomy is not a standard procedure for peripheral burns. It is primarily used for relieving tension in the fingers and toes due to fingers fusing together (digit contractures) or relief of compartment syndrome in the extremities. It is not relevant for peripheral circumscribed burn lesions.

**Clinical Pearl:** In treating burns, it is essential to consider the severity, location, and potential complications. Applying cold water immediately after the burn occurs is crucial, and the choice of dressings depends on the depth and location of the burn. For instance, moist dressings help in healing of deep burns, whereas for superficial burns, a sterile dressing is usually sufficient. Injuries to the head and neck typically require special care, and escharotomy is only indicated for specific situations involving compartment syndrome or digit contractures.
