Correct Answer is A
Explanation
A. Airway obstruction
Burns involving the head, neck, or chest put the client at risk for inhalation injury or airway edema, which can rapidly become life-threatening.
B. Contractures
This is a long-term complication, not an immediate concern.
C. Infection
While a serious risk, it is not as immediate as airway obstruction in the acute phase.
D. Fluid imbalance
Important, especially within the first 24 hours, but airway compromise takes precedence when head/neck/chest burns are involved.
