Step-by-step explanation:
The question is regarding the discharge planning for a child who will be requiring wet to dry dressing changes at home. The correct element to include in the plan of care to ensure that the parents are prepared to perform the dressing changes is to arrange for a step by step training sequence for wet to dry dressing changes with the parents of the child, which includes a return demonstration to evaluate understanding. The parents should receive direct supervision of a registered nurse during the training to ensure they understand each part of the process. This direct supervision and hands-on training ensure that the parents are competent in performing the task at home, maintaining sterility, and responding to any needs or issues that may arise during the dressing changes.
