RCIS Mock Exam: Questions And AnswersIn 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 Correct Ans - 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
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 Correct Ans - The left sided AV
groove artery is the Cx and its branches are termed OMs
The aortic dicrotic notch marks the beginning of ventricular:
a- systole
b- isometric relaxation
c- end diastolic pressure
d- slow filling phase Correct Ans - B. The systolic pulse is divided by a
midsystolic dip indicating a sudden ejection followed by increased resistance
and then secondary release.
End-diastolic stretching of the ventricular muscle fibers is termed:
a- preload
b- afterload
c- inotropism
d- chronotropism Correct Ans - Preload refers to the filling of the
ventricular chambers in diastole
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 Correct
Ans - 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
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 Correct Ans - 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
Which of the following is NOT a clinical manifestation of shock?
a- pallor
b- metabolic acidosis
c- slow bounding pulse
d- falling blood pressure Correct Ans - Slow bounding pulse.
Tachycardia usually results to compensate for decreased tissue perfusion
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
d- posterior lateral LV wall Correct Ans - Inferior infarctions usually
result from RCA infarction. The distal RCA feeds the lower 1/3 of the IV
septum and the inferior aspect of the LV depending on the extent of posterior
lateral RV branches
Aortic stenosis is classified as what type of disease?
a- restrictive
b- hypertrophic
c- inflow obstructive
d- outflow obstructive Correct Ans - Obstructive refers to stenosis or
inability to EXIT a chamber
An OLD myocardial infarct is seen on the ECG as a significant:
