volume and high residual volume (change
to the dashed lines)?
D 8. Left ventricular Preload will decrease with:
A. Increased CVP (from high blood volume)
B. Increased heart rate (by a positive chronotrope)
C. Increased residual left ventricular volume (from low stroke volume)
D. Weak ventricular muscle (from wall atrophy)
E. Increased PWP (pulmonary wedge pressure)
9. When a vascular clamp on the abdominal aorta below the renal arteries for 30 minutes is abruptly released,
which of the following quickly i ncreases?
A. Total Peripheral Resistance
B. Coronary Perfusion Pressure
C. Left Ventricular After Load
D. Slope of SA node phase 4 30 30 B A mmHg 20 20 mmHg 10. Swan-Ganz Pressure tracings.
Which statement below correctly matches the
corresponding tracing displayed on the right
(i.e., does answer A match tracing “A”)?
A. A decreased cardiac output will decrease
this pressure 10 10 0 0 B. The vessels that have this pressure have
an higher compliance than the vena cava
