Physical Therapy Assistant Practice Exam

Which symptom is NOT commonly associated with heart failure?

1. Peripheral edema

2. Fatigue

3. Cyanosis

4. Increased muscle strength

The correct answer is: Increased muscle strength

In the context of heart failure, increased muscle strength is not a symptom typically associated with this condition. Heart failure occurs when the heart is unable to pump blood efficiently, leading to a variety of symptoms due to inadequate blood flow and fluid congestion in the body. Peripheral edema, fatigue, and cyanosis are common symptoms related to heart failure. Peripheral edema occurs when fluid builds up in the tissues, leading to swelling, particularly in the legs and ankles, as a result of the heart's reduced ability to effectively circulate blood. Fatigue is prevalent because the body's tissues are not receiving enough oxygen and nutrients due to inadequate circulation, leaving the individual feeling tired and weak. Cyanosis, which refers to a bluish discoloration of the skin, occurs due to insufficient oxygenation of the blood, which can happen in heart failure when pulmonary circulation is compromised. In contrast, increased muscle strength is not a direct symptom of heart failure. In fact, individuals with heart failure often experience muscle weakness and a general decline in physical performance due to reduced cardiac output and overall deconditioning. As such, the correct choice highlights a symptom that stands apart from the typical manifestations of heart failure.
