A nurse is reinforcing teaching with the mother of a 2-month-old infant whose provider applied a Pavlik harness 1 week earlier for the treatment of developmental hip dysplasia. Which of the following statements by the mother indicates an understanding of the teaching?

Choice A rationale Adjusting the Pavlik harness straps is contraindicated, as the healthcare provider specifically set them to maintain the infant's hips in the optimal position of flexion and abduction, necessary for proper acetabular development. Frequent adjustment risks altering the prescribed angle, which could compromise treatment efficacy by allowing hip adduction or extension. Straps should only be adjusted by the provider during scheduled appointments to ensure optimal orthopaedic correction and joint congruence. Choice B rationale The Pavlik harness is designed to hold the femoral head within the acetabulum, promoting proper development but creating localized pressure points. Regular skin checks (e.g., three times daily or with diaper changes) are vital to detect signs of skin breakdown, redness, or irritation, especially under the straps and at pressure areas like the popliteal folds, which could lead to pressure ulcers or dermatitis if not addressed promptly by adjusting the padding or seeking provider consultation. Choice C rationale The diaper must be placed under the harness straps to prevent fecal or urinary soiling of the harness material, maintaining hygiene and preventing skin irritation from moisture trapped by the harness. Placing the diaper over the harness would necessitate unbuckling the leg straps for each change, which could disrupt the precisely set hip position required for therapeutic hip abduction and flexion. Choice D rationale Lotions and powders should be avoided under the harness or on skin areas in contact with the straps. These products can clump or retain moisture, leading to maceration and increased friction, which predisposes the skin to breakdown, dermatitis, and potential infection. Skin in contact with the harness should be kept clean and dry, allowing aeration to maintain skin integrity.
