SwanGanz catheter Correct Answers transducer
Describe the process of obtaining a pulmonary
wedge pressure. Correct Answers 1. When getting
vitals, blow up the balloon (should only be inflated
for 30 seconds)
2. The wave form should change to the pulmonary
artery wedge pressure, record number and deflate
3. Wave form should always return to pulmonary
artery (dicrotic notch)
formation of plaque within the arterial wall itself
Correct Answers atherosclerosis
How do you calculate MAP? Correct Answers
Systolic BP + (2*Diastolic BP)/3
How do you diagnose cardiac tamponade? Correct
Answers - increased fluid volume
- echocardiogram
- CXR
- hemodynamic monitoring
,How do you diagnose infective endocarditis?
Correct Answers positive blood culture
How do you manage decreased contractility?
Correct Answers beta blockade
How do you manage decreased CVP? Correct
Answers abx therapy, vasoconstrictors
How do you manage decreased CVP? Correct
Answers IVF/blood products and vasoconstrictors
How do you manage increased contractility?
Correct Answers electrolyte replacement
How do you manage increased CVP? Correct
Answers diuretics and vaasodilators
How do you manage increased SVR? Correct
Answers vasodilators, volume replacement,
tylenol, medications (abx), intraaortic balloon
pump
How do you perform the Allen's test? What
determines if it's patent or not? Correct Answers -
occlude the ulnar artery and have the pt squeeze
their fist, it should turn white then back to red
- if it remains white, it is not patent and you should
not put in a SwanGanz

caused pericarditis? Correct Answers bacterial -
abx
malignant - radiation or chemo
uremic - hemodialysis
How is acute pericarditis diagnosed? Correct
Answers Acute pericarditis is diagnosed when 2
out of 4 are present:
1. ST elevation
2. pericardial friction rub
3. pleural effusion
4. precordial chest pain

lovenox is started? Correct Answers at least 30
min
How long after the onset of chest pain should an
ECG be obtained? Correct Answers 10 minutes
inflammation of the vein Correct Answers
phlebitis
insufficient oxygen Correct Answers ischemia
loss of ability to contract forcefully Correct
Answers systolic heart failure
