A nurse is teaching home care to the parents of a preschool-age child who has heart failure. Which of the following information should the nurse include in the teaching?

A. Provide for periods of rest. Correct. Children with heart failure have reduced exercise tolerance and fatigue easily. Regular periods of rest help prevent overexertion and cardiac strain.B. Increase the child's oxygen flow rate until the child no longer has cyanosis. This can be dangerous. Oxygen therapy should be used as prescribed by a healthcare provider, as excessive oxygen can lead to oxygen toxicity or other complications, especially in children with heart conditions.C. Withhold digoxin if the child's pulse is greater than 100/min. Digoxin is typically withheld if the heart rate is too low (bradycardia), not high. The nurse should follow specific parameters set by the healthcare provider, but a pulse greater than 100/min is not a standard reason to withhold digoxin.D. Weigh the child once each month. In children with heart failure, daily weights are important to monitor fluid status and detect worsening heart failure. Monthly weighing is not frequent enough.
