Mock RCIS Exam
1. In normal fetal circulation the path of oxygenated blood returning from
the placenta passes though several fetal shunts. One of these normal
fetal pathways between the aorta and PA can be described as a:
a- L>R shunt termed the PDA
b- R>L shunt termed the PDA
c- L>R shunt termed the foramen ovale
d- R>L shunt termed the foramen ovale: the PA-AO shunt is the PDA and its
right to left. When the left heart pressure begins to exceed the right heart
pressure, that such a shunt would switch to left to right
2. What is the name of the coronary arteries which normally branch off
the Cx artery towards the apex of the heart?
a- diagonal branches
b- OM branches
c- acute marginal branches
d- posterior descending branches: The left sided AV groove artery is the Cx
and its branches are termed OMs
3. The aortic dicrotic notch marks the beginning of
ventricular: a- systole
,b- isometric relaxation
c- end diastolic pressure
d- slow filling phase: B. The systolic pulse is divided by a midsystolic dip
indi- cating a sudden ejection followed by increased resistance and then
secondary release.
4. End-diastolic stretching of the ventricular muscle fibers is
termed: a- preload
b- afterload
c- inotropism
d- chronotropism: Preload refers to the filling of the ventricular chambers
in diastole
5. The greatest expenditure of O2 during the cardiac cycle is used
to: a- open the aortic valve (isometric contraction)
b- open the mitral valve (diastolic filling)
c- eject blood out of the LV and into the AO (SEP)
d- overcome friction of blood viscosity and muscle compliance: A. One of
the chief benefits of IABP is to lower the pressure at which the aortic valve
opens, which decreases pressure work. This pressure work account for 90% of
the work done by the LV
, 6. Which of the following is a common result of right sided heart
failure? a- dyspnea
b- pulmonary congestion
c- pulmonary hypertension
d- neck vein distension: When the right side of the heart fails the RA and
systemic veins become engorged with blood. Pulmonary hypertension is only
a compensation to left sided failure
7. Which of the following is NOT a clinical manifestation of
shock? a- pallor
b- metabolic acidosis
c- slow bounding pulse
d- falling blood pressure: Slow bounding pulse. Tachycardia usually results
to compensate for decreased tissue perfusion
8. If an embolus were to lodge in the distal RCA at the crux, which
segment of the heart would suffer damage?
a- RV
b- inferior LV wall
c- anterior LV wall
