Which position is described as lying facedown with the knees and head resting on the bed with the bottom area lifted?

• A. Sims Position
• B. Prone Position
• C. Lithotomy Position
• D. Knee-Chest Position

Answer: (D)

This question tests recognizing how body positioning changes access to different parts of the body. The description—knees and chest resting on the bed with the buttocks elevated and the head likely turned to the side—fits the knee-chest position. In this setup, the patient is on their knees with the torso and thighs supported by the bed, the hips elevated, and the head positioned to allow comfortable breathing and visualization. This position is used to expose the posterior body, access the rectal/anal area, or relieve abdominal pressure in certain procedures. The other positions don’t match: lying flat on the abdomen with the chest and head aligned typically describes a prone position but not with the knees and chest resting on the bed and the buttocks elevated; lying on the back with hips flexed and legs in stirrups describes lithotomy; and a side-lying position with one leg bent describes Sims.
