Rationale: The most appropriate nursing intervention in this situation is to keep the newborn's body available for a few hours in case the parents change their minds. It is important to respect the parents' feelings and fears while also providing them with the opportunity to hold their child if they decide to do so later on.

This approach supports the parents' autonomy and allows them to grieve in a way that is meaningful to them.
