In Fowler's position, which pillow placement helps prevent posterior pelvic tilt?

• A. Under knees: prevents posterior pelvic tilt, reduce lumbar strain
• B. Behind head/upper back: maintain neutral head posture
• C. Under forearms: prevents shoulder subluxation
• D. Lumbar support

Answer: (A)

In Fowler's position, little changes in leg support can shift the pelvis and lower back alignment. Placing a pillow under the knees directly influences knee flexion so the legs’ weight doesn’t drive the pelvis into a backward roll. This helps keep the pelvis in a more neutral tilt and preserves the natural lumbar curve, reducing lumbar strain.

Other options address head posture, shoulder alignment, or simply provide lumbar support, but they don’t target pelvic orientation as effectively. A pillow under the knees specifically prevents posterior pelvic tilt by stabilizing the leg position and maintaining spinal alignment.
