Multiple Choice
Identify the choice that best completes the statement or answers the question.
____ 1. ACE inhibitors are a central part of the treatment of heart failure because they have more than one action to address the pathological changes in this disorder. Which of the following pathological changes in heart failure is NOT addressed by ACE inhibitors?
| A. | Changes in the structure of the left ventricle so that it dilates, hypertrophies, and uses energy less efficiently. |
| B. | Reduced formation of cross-bridges so that contractile force decreases. |
| C. | Activation of the sympathetic nervous system that increases heart rate and preload. |
| D. | Decreased renal blood flow that decreases oxygen supply to the kidneys. |
____ 2. One of the three types of heart failure involves systolic dysfunction. Potential causes of this most common form of heart failure include:
| A. | Myocardial ischemia and injury secondary to myocardial infarction |
| B. | Inadequate relaxation and loss of muscle fiber secondary to valvular dysfunction |
| C. | Increased demands of the heart beyond its ability to adapt secondary to anemia |
| D. | Slower filling rate and elevated systolic pressures secondary to uncontrolled hypertension |
____ 3. The American Heart Association and the American College of Cardiology have devised a classification system for heart failure that can be used to direct treatment. Patients with symptoms and underlying disease are classified as:
| A. | Stage A |
| B. | Stage B |

| D. | Stage D |
____ 4. Diagnosis of heart failure cannot be made by symptoms alone since many disorders share the same symptoms. The most specific and sensitive diagnostic test for heart failure is:
| A. | Chest x-rays that show cephalization and measure heart size |
| B. | Two-dimensional echocardiograms that identify structural anomalies and cardiac dysfunction |
| C. | Complete blood count, BUN, and serum electrolytes that facilitate staging for end-organ damage |
| D. | Measurement of brain natriuretic peptide to distinguish between systolic and diastolic dysfunction |
