CST Anesthesia & Surgical Positioning 3

Question 1

The Trendelenburg position is defined as the patient positioned:

Accepted Answer

Supine with the head tilted lower than the feet

Answer

In Trendelenburg, the patient lies supine on a table tilted so the head is lower than the feet, improving venous return and used for pelvic or lower abdominal surgery.

Question 2

Which surgical position is most commonly used for perineal, rectal, urologic, and gynecological procedures?

Accepted Answer

Lithotomy

Answer

The lithotomy position places the patient supine with legs elevated and supported in stirrups, providing excellent access to the perineum and lower pelvis.

Question 3

A serious complication specifically associated with prolonged lithotomy positioning is:

Accepted Answer

Compartment syndrome of the lower extremities

Answer

Prolonged lithotomy position elevates the legs above heart level, reducing arterial perfusion pressure and increasing venous pressure, which can cause compartment syndrome.

Question 4

When positioning a patient in the prone position, padding should be placed primarily under which structures?

Accepted Answer

Chest/thorax, hips/iliac crests, and knees

Answer

Prone positioning requires padding under the chest and iliac crests to protect the thorax and allow diaphragm excursion, and under the knees to prevent hyperextension.

Question 5

In the lateral decubitus position, which nerve is most vulnerable to pressure injury at the level of the fibular head?

Accepted Answer

Common peroneal (fibular) nerve

Answer

The common peroneal nerve passes superficially around the head of the fibula and is highly susceptible to compression in the lateral position, causing foot drop.
