Which finding would alert the nurse to potential respiratory obstruction in burns of the upper body?

• A. Deep breathing
• B. Pink-tinged, frothy sputum
• C. Rapid abdominal breathing
• D. Hoarse quality to the voice

Answer: (D)

Airway edema from inhalation injury can develop after burns to the upper body, and changes in voice are an early and important warning sign of potential respiratory obstruction. A hoarse quality to the voice indicates inflammation and swelling of the larynx and vocal cords, signaling that the airway is narrowing and could progress to obstruction. This prompts urgent airway assessment and preparation for possible airway support, such as securing the airway and ensuring adequate oxygenation. Other findings listed are less specific for imminent obstruction. Deep breathing reflects the work of ventilation but doesn’t pinpoint narrowing of the airway. Pink-tinged, frothy sputum can occur with inhalation injury or pulmonary edema but doesn’t inherently signal impending obstruction. Rapid abdominal breathing isn’t a typical indicator of upper airway obstruction. Thus, a hoarse voice best alerts to the risk of airway compromise in burns involving the upper body.
