SECTION I: PATHOPHYSIOLOGY & ETIOLOGY OF HEART FAILURE
1. A nurse is teaching a patient newly diagnosed with heart failure about the underlying
pathophysiology. Which statement accurately describes the primary mechanism of heart
failure?
A) The heart pumps blood too efficiently, causing fluid overload
B) The heart is unable to pump sufficient blood to meet metabolic demands of the body
C) The heart pumps excessively, causing decreased peripheral perfusion
D) The heart rate increases to compensate for decreased contractility
Answer: B) The heart is unable to pump sufficient blood to meet metabolic demands of the
body
Rationale: Heart failure is a clinical syndrome characterized by the heart's inability to pump
sufficient blood to meet the body's metabolic demands. This pump failure can result from systolic
dysfunction (impaired contraction) or diastolic dysfunction (impaired relaxation). The result is
inadequate cardiac output, leading to activation of compensatory mechanisms that ultimately worsen
the condition .

2. A 68-year-old patient with a history of hypertension and myocardial infarction is diagnosed
with heart failure. Which of the following is the most common cause of heart failure in the
United States?
A) Valvular heart disease
B) Coronary artery disease
C) Cardiomyopathy
D) Congenital heart defects
Answer: B) Coronary artery disease
Rationale: Coronary artery disease (CAD) and myocardial infarction (MI) are the most common
causes of heart failure in the United States. CAD leads to myocardial ischemia, which can cause
systolic dysfunction. Hypertension is another major risk factor, contributing to both systolic and
diastolic dysfunction. Valvular heart disease, cardiomyopathy, and congenital defects are less
common causes .
3. A nurse is explaining the Frank-Starling mechanism to a patient with heart failure. What is
the Frank-Starling law of the heart?
A) The heart rate increases in response to decreased blood pressure
B) The force of contraction is proportional to the initial length of the muscle fibers (preload)
