Which should the nurse consider when preparing a school-age child and the family for heart surgery?

A. It is important to acknowledge potential postoperative discomfort to set realistic expectations for recovery and reduce anxiety. B. Allowing the child to hear the ECG monitor sounds helps familiarize them with the equipment and can reduce fear or anxiety. C. Explaining that an endotracheal tube may be needed is more accurate than giving false reassurance, as it could be required during surgery. D. Showing unfamiliar equipment to the child can help reduce fear by familiarizing them with what they may encounter.
