|
| D. |
Blood loss may be more severe
|

Correct Answer � B
Explanation
|
|
Burns affecting the head and neck region raise immediate concern for airway compromise, especially in cases of inhalational injury due to:
-
Direct thermal injury to the upper airway
-
Edema of the larynx, pharynx, and trachea leading to obstruction
-
Exposure to toxic smoke and chemical inhalants which can damage the bronchial mucosa and lead to respiratory distress
Signs suggesting airway involvement include:
In such cases, early endotracheal intubation is often recommended before swelling progresses and airway access becomes difficult or impossible.
Why Other Options Are Incorrect:
A. Face is very vascular
-
While the face does have a rich blood supply, this does not increase the danger significantly. In fact, good vascularity helps in healing, not in worsening prognosis.
C. Renal failure is more frequent
-
Renal failure is a complication of extensive burns, especially when associated with hypovolemia or myoglobinuria from deep burns (e.g., electrical burns), not specifically due to head and neck burns.
D. Blood loss may be more severe
-
Burns generally do not result in massive blood loss. The primary issues are fluid loss, infection, and organ dysfunction. Hemorrhage is more relevant in traumatic injuries, not burns.
