seen in precordial leads

Question 4

Answer 4

RCA

Question 5

Which axillary artery is preferenctiall y cannulated?

Answer 5

L. lower incidence of embolization of carotid

ischemia and brachial plexus injury

Question 6

Which pts is the cannulation of dorsalis pedis and posterior tibial arteries contraindicated in ?

Answer 6

peripheral vascular disease and DM

Question 7

Name the veins in AC fossa. Wheich one has the largest lume and presents least obstruction to central venous cannulation?
