4. SIGNS AND SYMPTOMS:
Signs symptoms of burn develop of depth of the burn as well as extent of

2. Skin becomes pink or red colour
3. It may form small thin blister
4. Usually heal itself within 3 to 7 days
2nd degree burn:
1. Part of the skin damaged or destroyed
2. Epidermis and dermis both are affected
3. Thicken walled blister appear all over the burned area

2. Cover burns with sterile on clean cloths.
3. In case of chemical burn, clothing which has been socked
by the chemical agent must be removed immediately.
4. Assess for associated trauma.
5. Evaluate the degree and extent of the burn and treat life –
threatening condition.
6. Ensure a patient airway and administer 100% oxygen as
prescribed, if the burn occurred in an enclosed area.
7. Monitor for respiratory distress.
8. Initiate peripheral IV access to non-burned skin proximal
to any extremity burn.

7. 9. Assess for hypovolemia and prepare to administer IV
fluids to maintain fluid balance.
10. Monitor vital signs closely
11. Insert a foley’s catheter as prescribed, and maintain
urine output at 30 to 50 ml per hour.
12. Maintain NPO status.
13. Insert a nasogastric (NG) tube as prescribed, to
prevent paralytic ileus, to prevent vomiting, and to
reduce the risk of aspiration.
14. Administer tetanus prophylaxis as prescribed.
15. Administer pain medication, as prescribed, by the IV

include cleansing, debriding loose tissue, and
removing any damaging agents, followed by the
