You certainly have vaild points. The wide range of nursing positions, some of those things are true, and then none of them are true. Mostly your concerns are experienced at the bedside, but this is the frontlines of nursing where your experience will shape your career. But this profession isn't for everybody, and always examine why you went into it in the first place.
With that said,
1. DO you like/hate your job? why? I have a love/extreme dislike relationship with it. You have your good days and bad days. Any number of reasons can bring about this dislike, but I won't go into them.
2. DO you recommend nursing career for students? why? It depends on many factors, but generally yes.
3. DO you regret going into nursing career?? I sometimes do, because of the strain it places on me family-wise. If I got away from the bedside I probably be better off.
4. Is it true that there are variety of nursing jobs in one hospital?? for example if you hate your area/floor you can pick a different one in the same hospital and have totally different experience?? Absolutely. Working in procedures, cath labs, etc is much different than your garden variety floor. However, these jobs are at a premium and very specialized so it's sometimes hard to get into.
