A nurse is caring for a 2-month-old infant who has heart failure. Which of the following actions should the nurse take?

A. Limiting feeding time to 30 minutes helps reduce the infant's workload and prevent fatigue, which is important for infants with heart failure. B. Weighing the infant daily is more appropriate to monitor for fluid retention, which is a key concern in heart failure. C. Placing the infant in the prone position is contraindicated due to the risk of sudden infant death syndrome (SIDS). The infant should be placed on their back for sleep. D. Oxygen saturation should be checked more frequently than every 6 hours in an infant with heart failure, especially when monitoring for signs of distress.
