A nurse is assessing a toddler who has heart failure. Which of the following findings should the nurse expect?

Rationale: A. Heart failure in children typically causes tachycardia (not bradycardia) as the heart attempts to maintain cardiac output. B. Shortness of breath is a common manifestation of pediatric heart failure due to pulmonary congestion and impaired oxygenation. C. Children with heart failure often have decreased urine output due to reduced renal perfusion. D. Weight gain, not weight loss, is expected because of fluid retention and edema.
