A

25-35

31
Q

The key, diagnostic indicator for MI seen on an EKG is

A

An elevated ST segment in 2 continuous leads

32
Q

The vessel most commonly used for coronary artery bypass grafting (cabg) is the

A

Greater saphenous vein

33
Q

A possible complication of rupture or hemorrhage of the lipid core into the plaque issue

A

The formation of a thrombus

34
Q

A positive diagnosis of metabolic syndrome occurs when three of the following six conditions are met:

A 
Insulin resistance 
Dyslipidemia 
Elevated levels of CR protein 
Central obesity
Hypertension
Elevated fibrinogen levels
35
Q

List seven symptoms seen in postpericardiotomy syndrome:

A

Fever, pericardial pain, pleural pain, dyspnea, pericardial effusion, pericardial friction rub and arthralgia

36
Q

What is an atheroma

A

Plaque is a fibrous cap of smooth muscle cells that form over lipid deposits within the arterial vessels, protrude and narrow the lumen, and obstructs blood flow.
