Which position describes lying on the back with the face upward?

The dorsal recumbent position accurately describes lying on the back with the face upward. This position is characterized by the patient lying supine, which is another term for being on the back, often with the knees bent and feet flat on the bed or surface. This positioning is commonly used in medical examinations and procedures, as it provides easy access to the abdomen and pelvic area.

In contrast, the prone position refers to lying on the stomach, which is the opposite of being face upward. The sitting position involves being upright, and the lateral position indicates lying on one side. Each of these positions serves different purposes in clinical settings but does not represent lying on the back with the face upward as the dorsal recumbent position does.
