HESI Cardiology Practice Exam

In chronic heart failure, dependent edema is a common clinical finding due to fluid accumulation in the body as a result of poor circulation and ineffective heart pumping. This edema typically worsens by evening since gravity causes fluid to pool in the lower extremities when a person is upright throughout the day. This phenomenon aligns with the pathophysiology of heart failure, where compromised cardiac output leads to increased venous pressure and fluid leakage from the capillaries into the interstitial spaces.

Other symptoms and findings associated with chronic heart failure include fatigue, shortness of breath, and cough, but dependent edema distinctly illustrates the fluid retention characteristic of the condition. Options like chest pain that decreases with rest, palpitations while resting, and frequent coughing with yellow sputum may indicate other conditions such as angina, arrhythmias, or respiratory infections, respectively, and are less specific to chronic heart failure.
