To assess for heat inhalation in a client with deep burns, what should the nurse first observe for?

Observing for nasal discharge containing carbon particles is critical in assessing heat inhalation in a client with deep burns. When a person inhales smoke or hot gases, especially during a fire, carbon particles can enter the respiratory tract and lead to compromised airway integrity and function. The presence of carbon in nasal discharge indicates exposure to smoke or heated air, which can cause significant respiratory issues. This observation is particularly concerning, as heat inhalation can lead to airway edema, respiratory distress, and potentially airway obstruction, all of which require immediate medical attention.

Other aspects like changes in chest x-ray findings, sputum containing blood, and alterations in arterial blood gases may be relevant for assessing respiratory distress or injury over time, but identifying carbon particles in nasal discharge serves as an immediate indicator of the potential for serious complications from heat inhalation. Therefore, this observation is crucial for prompt intervention and management of the client's condition.
