Which of the following describes a benefit of Fowler's position?

• A. Increased risk of aspiration
• B. No effect on breathing
• C. Relaxation of abdominal muscles and improved breathing
• D. Worsened chest expansion

Answer: (C)

Fowler's position raises the head of the bed so the upper body is elevated. This setup uses gravity to help the chest and diaphragm expand more effectively. When the abdomen isn’t pressing down as much on the diaphragm, the diaphragm can move downward more freely during inspiration, allowing a larger stroke of air into the lungs. That greater diaphragmatic excursion promotes deeper, easier breaths and better ventilation. The abdominal muscles tend to relax because the breathing mechanics are more efficient in this position, which further supports easier breathing. Additionally, being upright generally lowers the risk of aspiration compared with lying flat and improves overall chest expansion and cough effectiveness. So the benefit described as relaxation of abdominal muscles and improved breathing best captures what Fowler's position does.
