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
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
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 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 - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔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
