1)Dyspnea and nocturnal cough
2)Confusion,difficulty concentrating,and headache
3)Cold,pale legs and feet
4)None of the above

Question 9

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.

Question 10

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.

Question 11

What is oncotic pressure?
1)A pressure reading within the inferior vena cava
2)A force that attempts to pull fluid from the interstitial and intracellular spaces
3)A force that attempts to push fluid out of the capillary pores into interstitial and intracellular spaces
4)A pressure reading upon inflation of the balloon on the tip of the Swan-Ganz catheter

Question 12

How is systolic dysfunction different from diastolic dysfunction?
1)In systolic dysfunction,the ventricle has difficulty ejecting blood out of the chamber.
2)In systolic dysfunction,the ventricle has difficulty relaxing and is unable to expand fully.
3)In systolic dysfunction,the ventricle pumps out insufficient blood volume.
4)In systolic dysfunction,the ventricle has low blood volume.

Question 13

Which fluid is found at the capillary-cell interface fluid compartment that is found inside the capillary?
1)Intracellular fluid
2)Interstitial fluid
3)Extracellular fluid
4)None of the above

Question 14

How is chronic heart failure different from acute heart failure?
1)Chronic heart failure is the rapid,sudden development of heart failure.
2)Chronic heart failure gradually develops over a long period of time.
3)Chronic heart failure is caused by substantial ventricular muscle injury.
4)Chronic heart failure is referred to as cardiogenic shock.

Question 15

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."

Question 16

2)"RAAS is a mechanism that decreases blood pressure."
3)"RAAS is a mechanism that increases blood volume in response to increased renal perfusion."
4)"RAAS is a mechanism with detrimental effects that decrease workload for the left ventricle."
