MOCK RCIS EXAM WITH COMPLETE QUESTIONS AND ACCURATE ANSWERS RATED A+ 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 Correct Answer 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 Answer 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 Answer 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 Answer 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 Answer 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 Answer 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 Answer Slow bounding pulse. Tachycardia usually results to compensate for decreased tissue perfusion
