Nurses caring for a pediatric client can most strengthen a child's sense of security by:
a. providing a unit and hospital handbook of rules and posting the dos and don'ts on the walls there children can see them
b. letting the children know then they will be leaving, who will be caring for them, and then they will be back, and saying good-bye then they leave
c. giving the children enough toys, games, and stuffed animals to play with
d. telling the children then meals will be and what the menu will be for each meal as well as then they will have nothing by mouth (NPO) and for how long
