TNCC Burn Management 3

Question 1

A burn patient's urine output drops to 0.3 mL/kg/hr despite adequate fluid resuscitation. The most appropriate intervention is:

Accepted Answer

Increase IV fluid rate to achieve target output of 0.5–1 mL/kg/hr

Answer

Target urine output for burn patients is 0.5–1 mL/kg/hr; inadequate output indicates under-resuscitation requiring increased fluid administration.

Question 2

Which electrolyte abnormality is most commonly seen in the first 24–48 hours following a major burn injury?

Accepted Answer

Hyperkalemia

Answer

Cell lysis from burn injury releases intracellular potassium, causing hyperkalemia in the acute phase of major burns.

Question 3

A patient sustains a hydrofluoric acid burn to the hand. After copious irrigation, which specific treatment is required?

Accepted Answer

Calcium gluconate gel application

Answer

Hydrofluoric acid causes systemic fluoride toxicity and hypocalcemia; calcium gluconate neutralizes fluoride ions and is the antidote.

Question 4

When transferring a major burn patient, which criterion from the American Burn Association meets criteria for transfer to a burn center?

Accepted Answer

Partial-thickness burns greater than 10% TBSA

Answer

The ABA recommends burn center transfer for partial-thickness burns >10% TBSA, among other criteria including full-thickness burns and special area involvement.

Question 5

In a burn patient with suspected cyanide poisoning from smoke inhalation, what is the recommended antidote?

Accepted Answer

Hydroxocobalamin

Answer

Hydroxocobalamin (Cyanokit) is the preferred antidote for cyanide poisoning in burn patients as it does not cause methemoglobinemia unlike nitrite-based antidotes.
