Final answer:
The nurse can give Martha information about Edna's condition if Edna has signed a release form, Martha comes to the hospital, or Martha can provide evidence of her connection to Edna.
Step-by-step explanation:
In order for the nurse to give Martha information about Edna's condition, Martha needs to fulfill certain conditions:
- If Edna has signed a release form on which Martha is listed. This means that Edna has given specific consent to allow Martha to receive information about her condition.
- If Martha comes to the hospital in person to request the information. This ensures that Martha herself is physically present and can verify her identity as Edna's sister.
- If Martha can prove she knows Edna. Martha may need to provide additional evidence, such as personal knowledge about Edna, to establish her relationship and legitimacy in receiving the information.
