In which position is a resident lying on the abdomen with knees pulled toward the abdomen and legs separated?

• A. Prone position
• B. Sim's position
• C. Lithotomy position
• D. Knee-chest position

Answer: (D)

The description fits the knee-chest position. In this position the resident lies on the abdomen with the knees drawn toward the chest and the legs spread apart, usually with the buttocks elevated. This configuration exposes the posterior body surfaces and perineal area for certain exams or procedures. It’s distinct from prone (lying flat on the stomach with the head turned to one side and arms positioned), Sim’s position (a semi-prone side-lying with one knee drawn forward), and lithotomy (supine with hips and knees flexed and legs in stirrups).
