A burn patient's urine output drops to 0.3 mL/kg/hr despite adequate fluid resuscitation. The most appropriate intervention is:
Answer: Increase IV fluid rate to achieve target output of 0.5–1 mL/kg/hr
Target urine output for burn patients is 0.5–1 mL/kg/hr; inadequate output indicates under-resuscitation requiring increased fluid administration.
Which electrolyte abnormality is most commonly seen in the first 24–48 hours following a major burn injury?
Answer: Hyperkalemia
Cell lysis from burn injury releases intracellular potassium, causing hyperkalemia in the acute phase of major burns.
A patient sustains a hydrofluoric acid burn to the hand. After copious irrigation, which specific treatment is required?
Answer: Calcium gluconate gel application
Hydrofluoric acid causes systemic fluoride toxicity and hypocalcemia; calcium gluconate neutralizes fluoride ions and is the antidote.
When transferring a major burn patient, which criterion from the American Burn Association meets criteria for transfer to a burn center?
Answer: Partial-thickness burns greater than 10% TBSA
The ABA recommends burn center transfer for partial-thickness burns >10% TBSA, among other criteria including full-thickness burns and special area involvement.
In a burn patient with suspected cyanide poisoning from smoke inhalation, what is the recommended antidote?
Answer: Hydroxocobalamin
Hydroxocobalamin (Cyanokit) is the preferred antidote for cyanide poisoning in burn patients as it does not cause methemoglobinemia unlike nitrite-based antidotes.
Which topical agent is contraindicated in burn patients with sulfonamide allergy?
Answer: Silver sulfadiazine (Silvadene)
Silver sulfadiazine contains a sulfonamide component and is contraindicated in patients with sulfa drug allergies.
A child presents with scald burns in a stocking-glove distribution with clear demarcation and no splash marks. The nurse should prioritize:
Answer: Documenting and reporting suspected non-accidental trauma
Symmetric, sharply demarcated scald burns without splash marks in a stocking-glove pattern are classic signs of forced immersion and non-accidental trauma in children.
