The Trendelenburg position is defined as the patient positioned:
Answer: Supine with the head tilted lower than the feet
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.
Which surgical position is most commonly used for perineal, rectal, urologic, and gynecological procedures?
Answer: Lithotomy
The lithotomy position places the patient supine with legs elevated and supported in stirrups, providing excellent access to the perineum and lower pelvis.
A serious complication specifically associated with prolonged lithotomy positioning is:
Answer: Compartment syndrome of the lower extremities
Prolonged lithotomy position elevates the legs above heart level, reducing arterial perfusion pressure and increasing venous pressure, which can cause compartment syndrome.
When positioning a patient in the prone position, padding should be placed primarily under which structures?
Answer: Chest/thorax, hips/iliac crests, and knees
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.
In the lateral decubitus position, which nerve is most vulnerable to pressure injury at the level of the fibular head?
Answer: Common peroneal (fibular) nerve
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.
The beach chair (modified sitting) position is most commonly used for which type of surgery?
Answer: Shoulder arthroscopy and ear surgery
The beach chair position elevates the head of the table and flexes the knees, providing optimal access to the shoulder joint and lateral head/neck structures.
When transferring and positioning a patient on the OR table, the surgical technologist's primary concern should be:
Answer: Protecting patient safety, maintaining circulation, and preventing nerve and pressure injuries
Patient safety is the highest priority; correct positioning must preserve neurovascular integrity, prevent pressure injuries, and maintain physiologic function throughout the procedure.
