The nurse should inform the patient that some of the test results are back and provide the patient with the opportunity to receive the results in private. The patient is not a minor and is not required to share health information with her mother. Repeating the test is unnecessary; further diagnostic testing, such as ultrasound, would be the next step if complications are present. The mother should not be informed in the hall, as the patient is an adult and can chose to share her information with her mother or not. The nurse should not ask the mother to leave; the nurse should ask the patient for her preferences first.
