PATHOPHYSIOLOGY EXAM 3
Which of the following describes the pericardial cavity?
1) It contains sufficient fluid to provide a protective cushion for the heart.
2) It is a potential space containing a very small amount of serous fluid.
3) It is lined by the endocardium.
4) It is located between the double-walled pericardium and the epicardium.
2) It is a potential space containing a very small amount of serous fluid.
The normal delay in conduction through the AV node is essential for:
1) preventing an excessively rapid heart rate.
2) limiting the time for a myocardial contraction.
3) allowing the ventricles to contract before the atria.
4) completing ventricular filling.
4) completing ventricular filling.
The cardiac reserve is:
1) afterload.
2) the difference between the apical and radial pulses.
3) the ability of the heart to increase cardiac output when needed.
4) the extra blood remaining in the heart after it contracts.
3) the ability of the heart to increase cardiac output when needed.
The first arteries to branch off the aorta are the:
1) common carotid arteries.
2) pulmonary arteries.
3) coronary arteries.
4) subclavian arteries.
3) coronary arteries.
R and L
Cardiac output refers to:
1) the amount of blood passing through either of the atria.
2) the volume of blood ejected by a ventricle in one minute.
, Page 3 of 135
3) the volume of blood ejected by each ventricle in a single contraction.
4) the total number of heartbeats in one minute.
2) the volume of blood ejected by a ventricle in one minute.
CO = /1min
SV = /contraction
A partial obstruction in a coronary artery will likely cause:
1) pulmonary embolus.
2) hypertension.
3) angina attacks.
4) myocardial infarction.
3) angina attacks.
partial = angina, complete = MI
Calcium-channel blocking drugs are effective in:
1) reducing the risk of blood clotting.
2) decreasing the attraction of cholesterol into lipid plaques.
3) reducing cardiac and smooth muscle contractions.
4) decreasing all types of cardiac arrhythmias.
3) reducing cardiac and smooth muscle contractions.
The term cardiac arrest refers to which of the following?
1) Condition where cardiac output is less than the demand
2) A decreased circulating blood volume
3) Missing a ventricular contraction
4) The cessation of all cardiac function
4) The cessation of all cardiac function
Which of the following is most likely to cause left-sided congestive heart
failure?
1) Incompetent tricuspid heart valve
2) Chronic pulmonary disease
3) Infarction in the right atrium
4) Uncontrolled essential hypertension
, Page 4 of 135
4) Uncontrolled essential hypertension
HTN = high systemic BP, so high aortic pressure causes LVH, causing LHF
In an infant, the initial indication of congestive heart failure is often:
1) distended neck veins.
2) feeding problems.
3) low-grade fever and lethargy.
4) frequent vomiting.
2) feeding problems.
A sign of aortic stenosis is:
1) increased cardiac output.
2) congestion in the liver, spleen, and legs.
3) flushed face and headache.
4) a heart murmur.
4) a heart murmur.
MS, MR, AS, AI = the big murmurs
Narrowing of aorta
Unoxygenated blood enters the systemic circulation in children with tetralogy
of Fallot because:
1) the aorta and pulmonary artery have exchanged positions.
2) pulmonary stenosis changes the ventricular pressures.
3) the left ventricular wall has hypertrophied.
4) the septal defect allows exchange of blood between the atria.
2) pulmonary stenosis changes the ventricular pressures.
TOF is the most common cyanotic VSD
4 signs - VSD, RVH, overriding aorta, pulmonary stenosis
Septic emboli, a common complication of infective endocarditis, are a result of
the fact that:
