Answer 15

LEFT 5th ICS at sternal border

Question 16

where do auscultate the mitral valve?

Answer 16

LEFT 5th ICS at MCL

at location of apex beat

where do you listen for valve sounds?

Answer 18

listen downstream from flow of blood through valves

what is the anatomical location of the mitral valve?

Answer 22

oblique

LEFT 4th ICS at sternal border

ask pt to turn head to side to see SCM

just under jaw line

Question 25

what are the 2 sites where the brachial artery can be felt?

Answer 25

1st one: mid arm - medial side of arm (mid way b/ shoulder and elbow). between biceps brachii and triceps brachii tendon
2nd one: cubital fossa

male nipple = 4th ICS

work down from here

Answer 33

radial nerve
biceps brachii tendon
median cubital vein
brachial artery
median nerve

Question 34

how do you make veins of arm more prominent for OSPE?
