A nurse is providing care for an infant who has heart failure and is being discharged from the hospital. When providing discharge education, which of the following clinical manifestations should the nurse ensure caregivers are able to identify as signs of worsening heart failure?

Rationale: A. Tachypnea and diaphoresis with feeding, poor weight gain, and irritability: Tachypnea and sweating during feeds indicate increased cardiac workload, poor weight gain reflects inadequate nutrition due to fatigue, and irritability can result from decreased perfusion and hypoxia. Caregivers should be able to identify these signs promptly. B. Cough, edema, and irregular heart rate: While cough and edema may occur in older children or adults with heart failure, they are less specific in infants. Irregular heart rate can indicate arrhythmia but is not the most sensitive early marker of heart failure worsening in this age group. C. Abdominal pain, poor appetite, and cough: Poor appetite may be present, but abdominal pain is not a typical early sign of infant heart failure. Cough is more often associated with respiratory infections rather than early heart failure. D. Bradycardia, rapid weight gain, and irritability: Bradycardia is not an early sign of worsening heart failure in infants; it may indicate severe hypoxia or advanced decompensation. Rapid weight gain could suggest fluid retention, but in combination with bradycardia, it reflects a more severe state rather than an early warning.
