Which statement best differentiates cardiac afterload from cardiac preload?
1. Cardiac afterload is the volume of blood in the heart at the end of diastole.
2. Cardiac afterload is the amount of resistance that the ventricle must overcome.
3. Cardiac afterload is the factor that affects cardiac output.
4. Cardiac afterload is the amount of blood that enters the right atrium. - answer✔2. Cardiac afterload is
the amount of resistance that the ventricle must overcome.
1. Cardiac preload is referred to as the volume of blood in the heart at the end of diastole.
2. Cardiac afterload is referred to as the amount of resistance that the ventricle must overcome to pump
blood out of the heart.
3. Cardiac preload factors affect cardiac output. They often occur before contraction.
4. Cardiac preload refers to the volume of blood that enters the right atrium from the venous system.

How is stage C heart failure different from other stages of heart failure, according to the American
College of Cardiology/American Heart Association classification?
1. Clients will have unidentifiable structural or functional heart abnormalities.
2. Clients may develop structural heart disease associated with heart failure.
3. Clients may have current or prior symptoms of heart failure.
4. Clients may have advanced structural heart disease. - answer✔3. Clients may have current or prior
symptoms of heart failure.
1. Clients who have no identifiable structural or functional abnormalities are classified under stage A
heart failure.
2. Clients who have developed structural heart disease strongly associated with heart failure are
classified under stage B heart failure.
3. Clients with current or prior symptoms of heart failure associated with underlying structural heart
disease are classified under stage C heart failure.
4. Clients with advanced structural heart disease and marked symptoms of heart failure are classified
under stage D heart failure.

Heart failure is classified into four different stages by the American College of Cardiology/American
Heart Association. How is the condition of a client in stage B different from the condition of clients in
other stages?
1. The client in stage B is supported by a mechanical circulatory assist device.
2. The client in stage B is undergoing treatment for prior symptoms of heart failure.
3. The client in stage B has a history of a previous myocardial infarction.
4. The client with diabetes mellitus has a family history of cardiomyopathy. - answer✔3. The client in
stage B has a history of a previous myocardial infarction.
1. A client diagnosed with heart failure that is supported by a mechanical circulatory assist device and a
client who is frequently hospitalized for heart failure is categorized under stage D heart failure.
2. A client undergoing treatment for prior symptoms of heart failure and fatigue caused by systolic
dysfunction is categorized under stage C heart failure.
3. A client with a previous myocardial infarction and asymptomatic heart disease is categorized under
stage B heart failure.
4. A client with diabetes mellitus and a family history of cardiomyopathy is categorized under stage A
heart disease.

A client 50 years of age is diagnosed with Class III (moderate) heart failure. How is Class III heart failure
different from other classes of heart failure in the client, according to the New York Association of
Classification of Heart Failure?
1. The client with Class III (moderate) heart failure will feel comfortable with ordinary physical activity.
2. The client with Class III (moderate) heart failure will feel fatigue and palpitations but only with
ordinary activity.
3. The client with Class III (moderate) heart failure will have symptoms such as fatigue, palpitations, or
dyspnea while doing less than normal physical activities.
4. The client with Class III (moderate) heart failure will be unable to carry out physical activities
comfortably. - answer✔3. The client with Class III (moderate) heart failure will have symptoms such as
fatigue, palpitations, or dyspnea while doing less than normal physical activities.
1. The client with Class II (mild) heart failure will feel comfortable with ordinary physical activity.
2. The client with Class I (mild) heart failure will not experience fatigue, palpitations, or dyspnea while
doing ordinary physical activity.
3. The client with Class III (moderate) heart failure will experience fatigue, palpitations, or dyspnea while
doing less than ordinary physical activities but may be comfortable at rest.
4. The client with Class IV (severe) heart failure may not be able to carry out any physical activities
comfortably. The client may have symptoms of cardiac insufficiency at rest.

How does the heart function when a client is diagnosed with heart failure?
1. The decrease in preload causes high blood volume, filling the ventricle.
2. The ventricular muscle pumps the excessive blood out.
3. The stroke volume decreases when the ventricle ejects its blood.
4. The contractility and stroke volume decreases. - answer✔4. The contractility and stroke volume
decreases.
1. An increase in preload causes high blood volume, filling the ventricle.
2. The weakened ventricular muscle may not have the strength to pump the excessive volume of blood
out.
3. The stroke volume decreases when the weakened ventricle cannot eject the blood.
4. The increased preload filling can decrease the contractility and stroke volume in a failing heart.

A registered nurse is teaching nursing students about ischemic cardiomyopathy. Which statement made
by one of the student nurses indicates effective learning?
1. "Ischemic cardiomyopathy is the scarring of the heart muscle caused by coronary artery
insufficiency."
2. "Ischemic cardiomyopathy is the enlargement and hypertrophy of the left or right ventricles."
3. "Ischemic cardiomyopathy is the disorder that restricts the ventricle's ability to fully expand."
4. "Ischemic cardiomyopathy is a genetic predisposition for the muscular enlargement of the
interventricular septal wall." - answer✔1. "Ischemic cardiomyopathy is the scarring of the heart muscle
caused by coronary artery insufficiency."
1. The scarring of the heart muscle caused by coronary artery insufficiency and myocardial infarction is
known as ischemic cardiomyopathy.
2. The enlargement and hypertrophy of the left or right ventricles in response to chronic injury is known
as dilated cardiomyopathy.
3. The disorder that restricts the ventricle's ability to fully expand is known as restrictive
cardiomyopathy.
4. The disorder in which the left ventricular muscle is enlarged, usually on the side of the interventricular
septum, is known as hypertrophic cardiomyopathy.
