Final answer:
A patient with the palm facing down while lying is in the prone position, which is different from the supine and anatomical positions.
Step-by-step explanation:
A patient lying down with his palm facing down is said to be in the prone position. In this orientation, the person is face-down. The supine position is its counterpoint, where the patient would be lying face-up. These terms are frequently used in various medical settings, including physical examinations and surgical procedures. The anatomical position is different; it refers to a person standing upright with feet at shoulder width and parallel, toes forward, upper limbs held out to the side, and palms of the hands facing forward.
