While recovering from the anesthetic, what is the best position for Mrs. West?
- A. Supine with legs fully extended
- B. Prone with head turned to the side
- C. Lateral Sims with legs flexed
- D. Trendelenburg with head to the side
Correct Answer: D
Rationale: The correct answer is D: Trendelenburg with head to the side. This position helps prevent aspiration by promoting drainage of secretions from the mouth and reducing the risk of airway obstruction. Placing the patient in Trendelenburg position with the head to the side also helps facilitate proper blood flow and ventilation. Supine with legs fully extended (A) may increase the risk of airway obstruction and aspiration. Prone with head turned to the side (B) may obstruct the airway and hinder breathing. Lateral Sims with legs flexed (C) is not suitable for a patient recovering from anesthesia as it may not provide optimal airway clearance and respiratory support.
