Easy Physiological Adaptation Pathophysiology

A patient is diagnosed with congestive heart failure (CHF). The nurse is reviewing the pathophysiology of this condition with the patient. It is important to understand how CHF affects the heart's ability to pump effectively.

Which of the following statements best describes the pathophysiological process of congestive heart failure?

CHF causes an increase in cardiac output due to increased fluid volume.

CHF leads to a decrease in myocardial contractility, resulting in insufficient cardiac output.

CHF is characterized by an increase in systemic vascular resistance, not affecting cardiac output.

CHF results in enhanced myocardial oxygen delivery and improved heart function.
