Trendelenburg position is characterized by which of the following?

• A. Feet are higher than the head by 15-30 degrees
• B. Head is higher than the feet by 15-30 degrees
• C. The patient sits upright with legs extended
• D. The patient lies on the abdomen

Answer: (A)

Trendelenburg involves the patient lying on the back with the entire body tilted so that the feet are higher than the head by about 15–30 degrees. This position shifts blood toward the upper body and central circulation, increasing venous return to the heart and potentially improving blood flow to vital organs in some shock or hypotension scenarios. The other descriptions describe different positions: having the head higher than the feet is the reverse Trendelenburg, sitting upright with legs extended is not Trendelenburg, and lying on the abdomen is the prone position.
