Final answer:
Congestive heart failure may lead to difficulty breathing and pulmonary edema, which is fluid accumulation in the lungs. Hence, the symptoms due to heart failure include both difficult breathing and fluid in the lungs, or both A and C. the correct answer is 'both A and C .
Step-by-step explanation:
Congestive heart failure is a chronic condition where the heart cannot pump blood effectively, which can lead to various symptoms. Among these, the disorder most commonly results in difficulty breathing and fluid in the lungs, known as pulmonary edema. It is crucial to note that while the term 'heart failure' may sound dire, it does not mean the heart has ceased functioning entirely. Instead, it refers to the heart's reduced ability to pump blood and supply oxygen to tissues throughout the body.
The insufficiency of cardiac muscle cells to contract properly due to dysfunctional endoplasmic reticula can lead to an inadequate number of calcium ions for an ample contractile force. As a consequence, fluid backs up into the lungs, causing pulmonary edema, which is life-threatening due to the impairment of gas exchange. If a patient is experiencing symptoms of heart failure, seeking medical care is crucial.
In addressing the student's question directly, the symptoms of congestive heart failure that they can present include both difficult breathing (A) as well as fluid in the lungs (C), thus the correct answer is 'both A and C'.
