A newborn infant diagnosed with developmental dysplasia of the hip must wear a Pavlik harness 23 hours a day. Which behavior by the mother best indicates that discharge teaching was effective?

Rationale: A. The mother reports that she has no questions about the care of the harness: Verbalizing no questions does not guarantee understanding or ability to perform proper care. Effective teaching requires demonstration and return demonstration to confirm competence. B. The nurse observes the mother removing and replacing the Pavlik harness: Observing the mother correctly remove and replace the harness demonstrates that she has learned and can safely manage the device, indicating that discharge teaching was effective. C. The nurse demonstrates removing the harness and the mother watches closely: Watching the nurse demonstrates the process but does not confirm that the mother can perform the task independently, so it is not a reliable indicator of teaching effectiveness. D. The mother describes problems that may occur while using the harness: Understanding potential problems is important, but describing them verbally does not confirm that the mother can safely apply and remove the harness, which is essential for proper care.
