Answer 4

interosseous arteries

Question 5

What artery is the stethoscope place over?

Answer 5

brachial a. - before it dives deep to tendon of biceps brachii

Question 6

olecranon bursitis

Answer 6

produces golfball size swelling at olecranon; repetitive use can cause fluid biuld up; need drain then inject w/ steroid then wrap

Question 7

septic elbow joint

Answer 7

red hot swollen joint; have to treat w/ IV antibiotics; may have to go in and clean it - i prostetic have to remove

Question 8

Nursemaid’s elbow

Answer 8

radial head subluxation; radial head is pulled out of the anular ligament; bend elbow and pronote/supinate to get back in

Question 9

fat pad sign

Answer 9

when a fx occurs, the hematoma occurs under the fat pad that surrounds humerus so it lifts the tissue off the bone and is visible on xray. if there is a fat pad sign, it means theres a fx somewhere

Question 10

Tennis elbow

Answer 10

lateral epicondylitis; repetitive use of extensors produces inflammation at origin of tendons where they attach to bone

Golfer’s elbow

Answer 11

medial epicondylitis; contracting of flexors repetivietly; rest, ice etc.

Question 15

coracobrachialis OI

Answer 15

coracoid to humerus

Question 16

bachialis OI

humerus to ulnar tuberosity

Question 17

where do the biceps insert?

Answer 26

usually long head - once ruptured will contract and cause bump in the arm

Question 27

PICC line

Answer 27

peripherally inserted central catheter; placed in the basilic vein and extends into brachial then axillary v. can stay in place for extended amt out time (used for chemo etc)
