A) Triangular Interval
B) Quadrangular Space
C) Triangular Space

A

B) Quadrangular Space

20
Q

A 32 year old man comes to the clinic with difficulty abducting the arm and has a tingling sensation on the upper lateral aspect of the arm. Which of the following nerves would you suspect has been damaged:

A. Median Nerve
B. Deep Radial Nerve
C. Thoracodorsal Nerve
D. Axillary Nerve

A

D. Axillary Nerve

21
Q

A 50 year old woman came to the hospital because she lost sensation to the skin of the lateral aspect of her forearm. The nerve that is damaged is a continuation of which of the following nerves:

A. Median Nerve
B. Ulnar Nerve
C. Musculocutaneous Nerve
D. Radial Nerve

A

C. Musculocutaneous Nerve

22
Q

A patient walks in the clinic, has pain and limited movement of the shoulder. You notice that when he pushes his hand against the wall there’s pronounced backward movement of the medial border of the scapula.
Which of the following nerves would you suspect has been damaged?

A. Median Nerve
B. Dorsal Scapular Nerve
C. Long thoracic Nerve
D. Suprascapular Nerve

A

C. Long Thoracic Nerve

Patient is pushing into wall that is scap. protraction, and there is backwards movement of the scapula, that is scapular winging. The serratus anterior is the muscle in charge of that and the Long Thoracic innervates that muscle.
