An infant is admitted to the pediatric unit with heart failure due to a congenital heart defect. What assessment finding would the nurse expect with this diagnosis?

A. Polyuria is not commonly associated with heart failure in infants; they are more likely to have oliguria or reduced urine output. B. Difficulty feeding is a common sign of heart failure in infants because the increased work of breathing and poor cardiac output make it hard for them to feed effectively. C. Bradycardia is not typically associated with heart failure; tachycardia is more common as the heart tries to compensate for decreased cardiac output. D. Bradypnea is uncommon in heart failure; tachypnea is a more likely symptom due to fluid overload and poor oxygenation.
