A nurse is reinforcing teaching about sibling adaptation with a parent of a child who has cystic fibrosis. Which of the following instructions should the nurse include in the teaching?

Choice A reason: Avoiding discussing the child's diagnosis with the sibling may create unnecessary secrecy and could hinder the sibling's understanding and coping. Choice B reason: Designating one parent to stay at home with the sibling may not be necessary, as both parents can still provide support and care for both children. Choice C reason: Avoiding having the sibling visit the child in the facility may isolate them and prevent opportunities for bonding and support. Choice D reason: This statement is correct. Encouraging phone calls between the siblings allows them to maintain communication, express their feelings, and support each other during the separation caused by hospitalization.
