Final answer:
A nurse developing a genogram can expect to obtain biological health risk information about the client.
Step-by-step explanation:
A genogram is a tool that visually represents the client's family structure and health history. By developing a genogram, the nurse can gather important information about the client's health risks and needs. The nurse can expect to obtain biological information, such as genetic diseases or conditions that may run in the client's family. This information will help the nurse determine the client's educational needs and provide appropriate interventions and support.
