  1. Which burn complication is characterized by conversion of a partial-thickness injury to a full-thickness injury due to infection or impaired perfusion?

    Answer: Burn wound conversion

    Burn wound conversion occurs when the zone of stasis progresses to coagulation due to inadequate resuscitation, infection, or local wound care failure.

  2. A burn patient develops progressive dyspnea, hoarseness, and stridor 4 hours post-injury. What is the priority intervention?

    Answer: Perform immediate endotracheal intubation

    Hoarseness and stridor indicate impending airway obstruction from inhalation injury; immediate intubation before complete obstruction is the priority.

  3. The hypermetabolic response following major burn injury peaks at approximately what time post-burn?

    Answer: 5-10 days

    The hypermetabolic response typically peaks around 5-10 days post-burn as inflammatory mediators drive a massive increase in metabolic rate.

  4. Which graft type uses the patient's own skin harvested from an unburned donor site?

    Answer: Autograft

    An autograft uses the patient's own skin and is the definitive, permanent wound coverage for full-thickness burns.

  5. A nurse notes a burn patient's urine output has dropped to 0.3 mL/kg/hr during resuscitation. What is the most appropriate action?

    Answer: Increase IV fluid rate to achieve 0.5-1 mL/kg/hr

    Urine output of 0.5-1 mL/kg/hr is the target in burn resuscitation; a low output indicates inadequate fluid delivery and requires rate increase.

  6. Which type of scar is raised, reddened, and confined to the original wound boundaries in a burn patient?

    Answer: Hypertrophic scar

    Hypertrophic scars are raised, erythematous, and remain within the wound margins, unlike keloids which extend beyond the original injury boundaries.

  7. Burn patients are particularly susceptible to hypothermia during wound care. What is the minimum recommended ambient room temperature for dressing changes?

    Answer: 85°F (29°C)

    Burn patients lose thermoregulatory ability; rooms should be warmed to at least 85°F (29°C) during wound care to prevent hypothermia.
