A nurse is assessing a child who has heart failure. Which of the following findings is a clinical manifestation associated with this diagnosis?

A. Bradycardia: Bradycardia (a slow heart rate) is not typically associated with heart failure. Heart failure usually leads to increased heart rate (tachycardia) as the heart attempts to compensate for poor cardiac output.B. Increased appetite: Increased appetite is not commonly seen in heart failure. In fact, children with heart failure often have poor appetite and may experience difficulty eating due to fatigue and shortness of breath.C. Tachypnea: Correct. Tachypnea is a common manifestation of heart failure as the body attempts to increase oxygen intake due to decreased cardiac output and poor perfusion.D. Tremors: Tremors are not typically associated with heart failure. They are more commonly related to neurological or metabolic conditions.
