Senior Seminar Positioning and Nerve Injury

   Most commonly injured upper extremity nerve during intraoperative procedures is the:

•   Median

•    Ulnar

• Saphenous

• Radial

  Hypotension that results from changing to a sitting position, should first be treated with:

 

•   Additional Rocuronium

• Fluid/Hextend

• Nitroglycerin

   

• Hydrocortisone

What is the second most injured nerve bundle?

 

• Radial nerve

• Femoral nerve

• Sciatic Nerve

• Brachial plexus

  Injury to the median nerve manifests as:

 

•     Wrist drop

•  Scapular winging

• Inability to oppose thumb and little finger

• Loss of sensation to pinprick of little finger

Common peroneal injuries occur if the legs are compressed _____________ against the

leg stirrups used for the lithotomy position.

 

• Inferiorly

• Medially

• Superiorly

• Laterally

Injury to the radial nerve from an improperly secured arm could cause:

 

• Ulnar deviation of fourth and fifth digits

• Unable to oppose thumb and little finger

• Wrist drop

• Third finger weakness

The nerve most commonly injured in the lower extremities.

 

• Common peroneal

• Femoral nerve

• Pudendal nerve

• Saphenous nerve

The ulnar nerve (is):

 

• becomes compressed at the medial epicondyle of the humerus     

• compressed when the elbow is in the extended position 

• protected by fibrous tissue when chronic inflammation is present

• can always be protected intraoperatively by supination of the forearm

For the lateral decubitus position, identify which lung would be under ventilated and overventilated. The dependent lung is:

 

• overventilated; Nondependent lung is overventilated

• under ventilated, Nondependent lung is overventilated

• under ventilated, Nondependent lung is under ventilated

• overventilated; Nondependent lung is under ventilated

When changing to this position, the patient's arms have the highest potential to fall off the arm boards.

 

• Lateral decubitus

• Supine Sitting

• Trendelenberg
