You are a nursing student on a community health clinical rotation. An 85-year-old woman is involved in a house fire. As she attempted to escape, she fell hit her head, and was briefly engulfed in flames and smoke before being rescued. She is now conscious but confused, lying on a stretcher outside the home. Her clothes are singed, and she has visible burns on her arms and chest, with labored breathing Which of the following signs would indicate a possible inhalation injury?

Rationale: A. Soot around the nose and mouth, hoarse voice, and singed nasal hair is correct because these are classic early indicators of inhalation injury. Inhalation injuries occur from thermal, chemical, or smoke exposure, damaging the upper and sometimes lower airway. Other signs include facial burns, stridor, coughing, labored breathing, and carbonaceous sputum. Early recognition is critical because airway edema can progress rapidly, requiring immediate assessment, supplemental oxygen, and possible intubation to prevent respiratory failure. B. Low blood pressure and cold, clammy skin is incorrect because these signs indicate hypovolemic or distributive shock, not inhalation injury. While hypotension may occur in burn patients due to fluid loss from extensive burns, it does not specifically identify airway involvement. Hypotension and poor perfusion are systemic signs rather than indicators of inhalation injury. C. Clear lung sounds and strong peripheral pulses is incorrect because these findings indicate adequate ventilation, oxygenation, and circulation. In a patient with potential inhalation injury, clear lung sounds and strong pulses do not suggest airway compromise, so these findings would not be expected in early or progressing inhalation injury. Relying on normal lung sounds can delay recognition of upper airway edema, which may develop before lower airway signs appear. D. Low blood pressure and cold, clammy skin is repeated and incorrect for the same reason as B. These findings reflect shock and poor perfusion but do not provide any direct evidence of inhalation injury. Focusing on these signs alone could delay airway intervention, which is the priority in suspected smoke or thermal inhalation.
