What action might a hospital social worker take in response to a family's discharge planning needs for a child requiring daily injections?

The most appropriate action for a hospital social worker in this scenario would be to arrange for a visiting nurse to administer the injections. This choice addresses the immediate medical needs of the child while considering the capabilities and resources of the family. A visiting nurse can provide the necessary expertise and support in managing the child's daily injections, ensuring that the child receives the required care in a safe and effective manner.

This course of action takes into account the potential stress and burden on the family, particularly if the mother may not feel confident in her ability to administer injections at home. Providing professional nursing care directly at home allows the family to focus on other aspects of care without the added pressure of daily medical procedures.

In contrast, other options, such as suggesting home health training for the mother, while beneficial, may not provide the immediate care needed. Discharging the child to a rehabilitation center does not align with the nature of the child's needs if the focus is specifically on administering daily injections at home. Lastly, providing resources for child care does not directly address the medical necessity of the daily injections, which is the primary concern in this situation.
