C) Balloon inflation optimizes aortic valve performance
D) Balloon deflation decreases left ventricular afterload - D) Balloon deflation decreases left
ventricular afterload
Which of the following hemodynamic profiles would benefit from aggressive fluid administration,
pressors and antibiotic therapy?
A) RAP 1, PAOP 4, SVR 1800, CO 2 L/min
B) RAP 5, PAOP 7, SVR 400, CO 8 L/min
C) RAP 5, PAOP 17, SVR 1900, CO 2 L/min
D) RAP 12, PAOP 7, SVR 1400, CO 5 L/min - B) RAP 5, PAOP 7, SVR 400, CO 8 L/min
The nurse needs to assess adequacy of the tubing/catheter system for the arterial line. Which of the
following interventions will best assess this?
A) Use heparinized flush
B) Level the transducer
C) Zero balance the transducer
D) Perform a square wave test - D) Perform a square wave test
Use of heparin, choice (A), may be used to maintain catheter patency, but is now seldom utilized;
leveling of the transducer, choice (B), is used to ensure accuracy of the pressures obtained; zeroing the
transducer, choice (C), eliminates the effects of atmospheric pressure on the physiologic pressure

, B) Factor X
C) PTT
D) FSP - A) D-dimer
The patient has acute renal failure with fluid overload, and continuous renal replacement therapy (CRRT)
has been ordered. Which of the following would indicate the need for CRRT rather than intermittent
hemodialysis?
A) hyperkalemia
B) MAP 45 mmHg
C) Acidosis
D) Severe hypoxemia - B) MAP 45 mmHg
Cardiogenic shock secondary to left ventricular failure will generally result in:
A) Decreased afterload
B) Narrow Pulse Pressure
C) Decreased Preload
D) Widening Pulse Pressure - B) Narrow pulse pressure
Pulmonary hypertension may result in which of the following?
A) Left HF
B) Right HF
C) Increased lung compliance
D) Arterial hypertension - B) Right HF
The patient with diastolic heart failure develops supraventricular tachycardia, heart rate 220/min. The
most dangerous hemodynamic effect is a decrease in:
A) Myocardial contractility
B) Coronary Artery perfusion
