Semi-Fowler's position is defined as?

• A. Head of bed elevated 60-90 degrees
• B. Head of bed elevated 30-45 degrees with legs straight
• C. Head of bed flat with arms at sides
• D. Head of bed elevated 0 degrees

Answer: (B)

Semi-Fowler's position is a moderate elevation of the upper body that helps with breathing comfort while keeping the legs straight. The head of the bed is raised about 30 to 45 degrees. This angle lifts the chest and allows the diaphragm to expand more fully, which can make breathing easier and reduce the effort needed to ventilate, especially for someone who is short of breath or recovering from surgery.

Keeping the legs straight helps maintain proper spinal alignment and reduces tension in the lower back, which supports overall comfort and stability in this position. Elevations higher than this (a much more upright posture) are used for other purposes, while lying flat would not provide the airway and comfort benefits of semi-Fowler's.
