Which of the following represents a sign of inhalation injury in burn patients?

The presence of wheezes in lung sounds is indicative of inhalation injury in burn patients. Wheezing occurs when there is narrowing or obstruction of the airways, which can happen as a result of heat or chemical exposure from smoke inhalation. Inhalation injuries can lead to bronchospasm and inflammation, causing these characteristic wheezing sounds upon auscultation.

Identifying this sign is critical in assessing a patient’s respiratory status, especially in the context of burns, where airway compromise is a significant concern. Early recognition of wheezing allows for prompt intervention, such as bronchodilator therapy, which can help alleviate airway constriction and improve breathing functionality.

Other options indicate varying degrees of respiratory status, but do not specifically point towards inhalation injury. For example, diminished breath sounds with clear lungs may suggest a different type of respiratory issue rather than an obstruction due to inhalation. Unlabored breathing typically suggests adequate oxygenation and airway stability, while the use of accessory muscles indicates increased respiratory effort, which may arise from various respiratory complications but isn't as specific to an inhalation injury as wheezing is.
