BJC Patient Care Technicians (PCT) Academy Practice Exam

Supine means lying flat on the back with the face upward. This position is used when you need access to the front of the body or to keep the body evenly aligned for certain exams and procedures. It’s distinct from lying on the stomach (prone position) and from positions where the head of the bed is raised, such as when the head is elevated to a Fowler or semi-Fowler angle. So the description "flat on back" best matches supine, while the other descriptions describe prone or elevated-head positions.
