Which ICU position involves lying flat on the back?

• A. Laying on stomach
• B. Lying on back
• C. 30-degree incline of head of bed
• D. Head-down tilt

Answer: (B)

Lying flat on the back refers to the supine position. In this position, the person is on their back with the face upward, arms at the sides, and the body horizontal. This is different from lying on the stomach (prone), which places the body face down; a 30-degree incline of the head of the bed, which is a semi-reclined position and not flat; and a head-down tilt, which tips the body so the head is lower than the feet (Trendelenburg). The description “lying flat on the back” matches the supine position, which is exactly what the question asks for.
