A nurse is teaching a parent of a 4-month-old infant who has developmental dysplasia of the hip and is prescribed a Pavlik harness. Which of following instructions on the use of a Pavlik harness should the nurse include in the teaching?

A. "Use lotion on the skin under the harness.": Lotions and powders should be avoided because they can cause skin irritation or breakdown when trapped under the straps. Instead, the skin should be kept clean and dry to prevent complications. B. "Place the diaper under the straps.": Positioning the diaper under the harness straps helps maintain cleanliness of the harness and prevents soiling. This is an important part of daily care to protect both the infant’s skin and the harness. C. "Avoid massaging the skin under the straps.": Gentle massage of the skin under the straps is encouraged to promote circulation and prevent skin breakdown. Avoiding massage could increase the risk of pressure injuries in these areas. D. "Adjust the harness straps weekly.": Parents should not adjust the harness straps at home. Adjustments must be made by the healthcare provider to ensure correct positioning of the hips and to avoid complications related to improper use.
