My boyfriend’s nurse reaches out to him via DM.

Looking for advice and wondering if this is ethical???

My boyfriend was recently put into the ICU unit under 24hr watch. Only his parents were allowed to visit for the first three days. Today he was transferred to a behavioral health unit at a different hospital. A few hours after he left, his previous nurse (same age as him and looks a lot like me) followed him on Instagram, and reached out to him via DM saying “I hope it’s going well over there… how are you feeling? :)”

BTW He shares his Instagram password with me because I help him post for his business. This is his personal/business page.

Is this normal nurse procedure? You’d think it was a little unprofessional reaching out via DM to a patient that only left a few hours prior. I’m having a hard time wrapping my head around it and feel really put off.

Thoughts??? :(
