A nurse is collecting a health history from the guardian of a 4-year-old child. Which of the following statements by the guardian is the priority for the nurse to address?

The guardian's observation about the child being withdrawn since the switch of daycare providers is particularly important. It suggests a change in behavior that could potentially indicate emotional or social difficulties. The nurse should explore this further to gather more information and assess the child's well-being in the new daycare setting. It is essential to ensure the child's emotional health and address any potential issues that may be affecting their well-being and development.
