AORN Surgical Positioning 2

Question 1

Which nerve is most at risk during prolonged lithotomy position due to compression at the fibular head?

Accepted Answer

Common peroneal nerve

Answer

The common peroneal nerve wraps around the fibular head and is highly susceptible to compression injury in lithotomy position.

Question 2

When positioning a patient in the lateral decubitus position, an axillary roll is placed to protect which structure?

Accepted Answer

Brachial plexus

Answer

The axillary roll is placed just caudal to the axilla to prevent brachial plexus compression from the weight of the thorax.

Question 3

A patient in reverse Trendelenburg position is at greatest risk for which complication?

Accepted Answer

Venous pooling in the lower extremities

Answer

In reverse Trendelenburg, gravity causes blood to pool in dependent lower extremities, reducing venous return and cardiac output.

Question 4

Which positioning device is specifically recommended by AORN to protect the ulnar nerve at the elbow?

Accepted Answer

Gel pad over the medial epicondyle

Answer

AORN recommends padding the medial epicondyle with gel or foam to protect the ulnar nerve from direct pressure.

Question 5

In the prone position, which abdominal positioning frame or roll placement is critical to prevent increased intra-abdominal pressure?

Accepted Answer

Chest and iliac crest support that frees the abdomen

Answer

Supports must be placed at the chest and iliac crests so the abdomen hangs free, reducing IVC compression and epidural venous bleeding.
