Elevation of the head of the bed in trauma care is used primarily to reduce the risk of what?

• A. Aspiration
• B. Hypotension
• C. Hypothermia
• D. Edema

Answer: (A)

Elevating the head of the bed in trauma care is about protecting the airway when there's a risk of vomiting or regurgitation. By tilting the patient up about 30 degrees, gravity helps keep any gastric contents away from the trachea, reducing the chance of aspiration during airway management, suctioning, or transport. This positioning also aids drainage of secretions and simplifies airway access. It isn’t aimed at preventing hypotension—raising the head can lower venous return in some patients—and it doesn’t directly prevent hypothermia or edema, though it may have minor secondary effects. So the primary purpose is to reduce the risk of aspiration.
