It is so obviously a 'no.' Just our of curiosity, why do you ask? Are you a pt was was "hit on" by a nurse? A nurse thinking of flirting? Just remember, 'ER' and the like are not a reliable representation of nursing.
My patients are barely conscious. I monitor their vitals, watch for post-operative complications, manage pain and ponv and so on... Hardly a romantic setting even if one was inclined to flirt.
I have never thought of a patient as attractive. That's simply not my mind-set at work. I find the notion of flirting with a patient ridiculous and of course utterly unprofessional.
I was going to say "depends on what you mean" but by explaining it was "a hot patient"--it is entirely inappropriate to flirt. If what you mean is to joke around and be friendly depends on the situation and the patient. If I have a patient who knows each time they see me, it is hardly anything nice, I do try and lighten the mood a bit "Yes, it is me Nurse Jade again. Like a bad penny I just keep turning up". Sometimes, it will lighten a situation. But again, depends.
If you are a bowel care consultant, it may make a patient feel more comfortable talking about something that most patients find really embarrassing if you do lighten the mood a tad. "I am Nurse Bowel Consultant and contrary to what you may be thinking I am not bowel obssessed...." or something along those lines.
