A nurse is providing teaching to the guardian of an infant who has heart failure. Which of the following instructions should the nurse include?

Heart failure in infants occurs when the heart is unable to pump effectively to meet the body’s metabolic demands, often due to congenital heart defects or cardiomyopathy. These infants tire easily, especially during feeding and activity, because of increased oxygen consumption and cardiac workload. Nursing care focuses on conserving energy, reducing stress, and supporting adequate nutrition and oxygenation. Teaching caregivers how to minimize cardiac demand is essential for preventing worsening symptoms. Rationale: A. Minimizing the infant’s environmental stimuli is important because excessive crying, noise, or activity increases oxygen demand and cardiac workload. Infants with heart failure have limited cardiac reserve and can quickly become fatigued or develop respiratory distress. A calm, quiet environment helps conserve energy and reduces stress on the heart. B. Placing the infant in a supine position is not ideal because it can worsen breathing difficulty by increasing venous return and reducing lung expansion. Infants with heart failure often breathe more comfortably in a semi-upright or elevated position, which decreases work of breathing and improves oxygenation. Supine positioning may increase respiratory distress. C. Bathing the infant every day may be too tiring for an infant with heart failure, especially if prolonged handling causes fatigue. Care should focus on clustering activities and conserving energy rather than creating unnecessary exertion. Hygiene is important, but bathing should be planned to avoid excessive stress and exhaustion. D. Allowing the infant to sleep through night feedings is inappropriate because infants with heart failure often require frequent, smaller feedings to meet nutritional needs without causing fatigue. Skipping nighttime feedings may result in inadequate caloric intake and poor weight gain. Consistent nutritional support is essential for growth and cardiac stability.
