A patient has severe pneumonia in the left lung and is breathing spontaneously. Which position usually improves oxygenation by allowing the healthier lung to receive more blood flow?
Correct answer: B. Right side-lying position
- A. Left side-lying position
- B. Right side-lying position
- C. Supine position
- D. Trendelenburg position
Explanation
The healthy lung is placed down because gravity directs more blood flow to that lung, improving ventilation and perfusion matching. This patient should therefore lie on the right side unless another condition prevents the position.
