Of course I have no clue what kind of nursing you mean, and with the different countries having different regulations about what a person called "nurse" can and cannot do.. well, you know better of course. I myself was once a nurse but only by title: my job was to clean rooms. However, I've seen my share of the health care people from the other side.
Nursing can be very physical. My schooltime friend did just bust her back very badly because a bit heavier lady wanted to go potty five times a night and she was alone in the night watch. (She was also too nice to tell her to stay put and use the appliances..) However, there is a chance that there is a lot of lifting and carrying and supporting and stuff going on in the nursing world, the difference to the warehouse work being the absence of liftforks. It might be very heavy and very un-ergonomical.
I'm not sure whether nursing has any problem solving in the picture. I have understood that it's the doctors that do that part while nurses (at least the lower ranked ones) only do menial tasks. I'd check this up first.
The hospitals can easily be places of strict hierarchy. At least in the one I worked there was no rule that a doctor wouldn't break (like "don't walk on a freshly walked floor you moron") and as a lowly temp nurseling I wasn't supposed to call them on that. There was one ward where the higher ranked nurses would actually help me, but they had an extraordinary head nurse. Also, the work load here is huge and the salaries are poor, and because nursing is still being considered a bit of a calling instead of a real job or, heaven forbid, a career, the situation is not really improving. A couple uncaring bastads would do the nursing world a lot good.
Then a rant about whether a nurse should be an F type or not:
Comforting and stuff can be done (in my opinion even better) without being an F. Remember how you felt when you lost someone (a gf walked out or whatever), hurt yourself and so on, and think what you'd wanted to hear then - then take that thing that'd comfort you best and offer it to the patients. Just look at them and see if it worked, if not, try something else.. Also, not actually sharing that feeling in an F way (aka "caring") is, as I see it, a good thing, because it makes you more concentrated on how the patient feels and not how YOU feel about the patient feeling bad.
This brings me to
specifically people who have experienced the same troubles in life as myself. I don't know if this is something specific to me because I have read quite a bit about ISTP's not really caring much about other people's problems. I can listen to problems as long as we are working toward a solution, but listening to a person go on and on endlessly about the perils of life...that I can't do. I can help you with your problems but I'm not going to listen to them without a plan of action.
That's stupid.
You should take a good look about what your goal is. What is helping and what is not? If you've gone through anything you should've noticed that there is no magic switch that someone ELSE can pull and that'd make everything all right. There is no problem for you to solve. There is no need to actually care about their problems and issues, either. One can NEVER really change the way another person is or thinks or behaves; the only person that can do this is he/she themselves. Very often the thing is that people have nobody to talk to and it's hard to get distance to the stuff that's happening when you can't let the feelings out. If you feel there's nothing you can say or do, just switch to "oh, really?" and "mh-hm".
You know the story about teaching a poor man to fish, instead of giving him one? There is no fish here. And learning fishing takes goddamned long thing to do and looks like they're doing nothing. And sometimes they're actually doing nothing, too..
Things that work best in the emotional crises in my opinion:
- Asking how the other one feels (and not assuming you know how they should in the situation they are in),
- listening to what they say (and not giving them personal advice because what do you know anyway, they probably heard it several times before) and
- being honest (and not telling what you assume they'd want to hear because that's just so damned fake).

Edit:
An example from an operating room, patient having pains during a surgery. The doctor says: "this doesn't hurt" and continues. The nurse looks at the patient and asks: "does it feel like this-and-this? Yes? Yeah, it can do that".
Edit 2:
Forgot this: No, I wouldn't be a nurse, because there's too much obeying orders and too little pay. I could be a doctor, I guess, if I wouldn't get this puke reflex every time I smell something bad. I could probably consider getting some kind of therapist degree..
