CBRN Burn Pathophysiology & Wound Care Management 4

Question 1

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

Accepted Answer

Burn wound conversion

Answer

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

Question 2

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

Accepted Answer

Perform immediate endotracheal intubation

Answer

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

Question 3

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

Accepted Answer

5-10 days

Answer

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

Question 4

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

Accepted Answer

Autograft

Answer

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

Question 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?

Accepted Answer

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

Answer

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.
