How were professional boundaries crossed in this case?

A nurse on a medical unit was caring for an elderly woman. The patient’s family visited frequently. The nurse, patient, and family spent a lot of time together, and the nurse was very helpful to the family. The nurse shared with the patient and family that her husband was out of work and her family was experiencing a difficult time. Her husband had applied for a job at many businesses, and in the course of the conversation, the nurse realized that her husband had applied to the patient’s son-in-law’s business. He had never been called for an interview.
