This far I have never even had the thought of crossing a boundary with a patient or family member. However, I have grown very fond of a family of a patient that I have been taking care of this past week. The patient's sister gave me her business card, and since I did not see her today I sent her an email thanking her for allowing me, as a student to take care of her brother while in the ICU. I also told her that since I did not have the son's contact information, to please thank him for me. She responded with his phone number and told me that he would be excited to hear from me. What do I do? I have a crush on the son, and have been pondering crossing that boundary. Has anyone ever been put in this situation? If so, what did you do? This afterall is not the patient, but the son of the patient... Thanks everyone in advance for your input.
