CBRN Burn Pathophysiology & Wound Care Management 5

Question 1

Which formula is used to estimate TBSA burned in adults using the palm of the patient's hand?

Accepted Answer

The 1% palm method

Answer

The patient's palm (including fingers) represents approximately 1% of TBSA and is useful for estimating scattered or irregular burn patterns.

Question 2

A patient has circumferential full-thickness burns to both lower extremities with absent distal pulses and paresthesias. What intervention is indicated?

Accepted Answer

Emergent escharotomy

Answer

Circumferential full-thickness burns create constrictive eschar that impairs circulation; escharotomy releases the constriction and restores distal perfusion.

Question 3

Which nutritional route is preferred for burn patients who have a functioning gastrointestinal tract?

Accepted Answer

Early enteral nutrition via nasogastric tube

Answer

Early enteral nutrition is preferred as it maintains gut integrity, reduces bacterial translocation, and supports the hypermetabolic response.

Question 4

Burn patients who receive prolonged silver nitrate 0.5% dressing treatment are at risk for which electrolyte complication?

Accepted Answer

Hyponatremia and hypochloremia

Answer

Silver nitrate leaches sodium and chloride from the wound, causing hyponatremia and hypochloremia that requires close electrolyte monitoring.

Question 5

A burn patient is receiving split-thickness skin grafts. Which post-operative assessment finding at the graft site would indicate graft failure?

Accepted Answer

Fluid collection (seroma or hematoma) beneath the graft

Answer

Seroma or hematoma beneath a graft prevents the graft from adhering to the wound bed, leading to graft failure due to impaired nutrient diffusion.
