Which statement about bed cradle is true?

• A. It keeps the top linens off the lower extremities.
• B. It raises the patient's feet higher than the head.
• C. It warms the patient with an electric pad.
• D. It reduces the mattress height.

Answer: (A)

A bed cradle is used to keep the linens away from the patient’s feet and legs. By lifting the top sheets and blankets off the lower extremities, it reduces friction, prevents skin irritation, and helps protect against moisture and pressure from the fabric as the patient moves. That makes the statement about keeping the linens off the lower extremities true. It doesn’t raise the feet higher than the head—that would be a different device or bed adjustment—nor does it warm the patient with an electric pad, and it doesn’t change mattress height.
