A nurse is planning care for an infant who has a prescription for a Pavlik harness. Which of the following actions should the nurse take?

The correct answer is B: Position the diaper over the straps with each change. This is important to prevent irritation and pressure sores on the infant's skin. Placing the diaper over the straps creates a barrier between the harness and the skin, reducing the risk of skin breakdown. Applying lotion (choice A) may cause the straps to slip, compromising the effectiveness of the harness. Lengthening the harness straps weekly (choice C) is not necessary and may alter the fit of the harness. Massaging the skin under the straps daily (choice D) can cause discomfort and does not address the primary concern of preventing skin irritation.
