I'm an Registered Nurse and have some fairly strong views FA. Good question
Prior to transition back in huge denial phase and had a trans patient. I was disgusted by the treatment by other nurses at the time. I was the only person who referred to the patient in their clearly preferred name, all other nurses or HCP's were borderline vulgar and completely disrespectful to the patient, statements such as "this is John, he wants to be called Jill. John came to us at ... " etc. even at that time when I was simply scared to look at websites that talked about what trans* people (Like, umm, Susans!

) was terrifying. However I knew that was just "not on" in terms of patient treatment, I wish I had said something to them then but I was new and "knew nothing" so it wouldn't have got through anyway.
The second trans person (maybe 8 months ago) I had as a patient had a significantly large physical and mental health background and tbh I don't think I'm qualified to comment on their medical or psychological treatments. When I was looking after them (I'm trying to be very ambiguous and not necessarily gender specific) I was very aware of their gender dysphoria and asked them which names and pronouns they wished to be called by and also gave them details for the local appropriate clinic for then GID (wow! what a difference 8 months make with DSMV). Unfortunately due to clinical limitations and the type of unit we were unable to consider further options (ie. they wanted to start HRT whilst significantly ill, something the doctors would strongly disagree on), although staff and my colleagues were much more accepting in my new (now) workplace.
Post full time (three and a half months from now) I would like to be much more of an active voice and advocate. Simply, now, me being not out at work I would absolutely correct people on inappropriate terms but may avoid full on confrontational events. Medical treatments and things, HRT and and any birth control etc. is shown to have a higher rate of DVT and clots was taught to us at uni but things like spiro are not common drugs outside renal (kidney), cardiac (heart) or endocrinology (hormones) circles and most nurses within general wards or surgical wards would likely have limited knowledge. I have pointed people in the right direction for information that they may not know however

Somehow people are to my knowledge oblivious to me transitioning at work though!
Maybe, maybe, I will re-try medical admission tests in the future (barely tried once and didn't get in, surprise), but I kinda like being a nurse and actually having a so called life
