In which position is the head of the bed lowered and the feet raised?

1. Sim's position

2. Trendelenburg's position

3. High Fowler's position

4. Sitting position

The correct answer is: Trendelenburg's position

Trendelenburg's position is characterized by having the head of the bed lowered and the feet elevated. This position is often used in medical situations to increase blood flow to the brain and vital organs, especially in cases of shock or hypotension. By elevating the feet, gravity aids in returning blood from the lower extremities to the upper body, potentially stabilizing a patient's condition. In contrast, Sim's position is typically used for certain examinations and procedures, particularly in accessing the rectal area, and does not involve the head being lowered or the feet elevated. High Fowler’s position involves sitting up with the upper body elevated significantly, which is beneficial for patients with respiratory issues but does not involve raising the feet. The sitting position, while it can vary, does not specify the relationship between the head and feet like Trendelenburg's position does. Therefore, the defining feature of the Trendelenburg position is why it stands out in this context.
