(student nurse) not my patient but my professor’s. she’s a maternity nurse. she had a patient who seemed fine, vitals were pretty good, etc. but when my professor went to help her to the bathroom, she looked her dead in the eyes and said “i’m going to die”. my professor told the attending physician but kinda brushed it off bc almost all moms feel somewhat shitty after giving birth and everyone figured she just wasn’t feeling well. turns out the patient was hemorrhaging and died shortly after saying that. 
her moral of the story was to listen to your patients when they say they aren’t feeling good. she’s never forgiven herself for that
