That's a great question and I like your answer. Drawing the line in nurse-patient relationships is a difficult one for many. For a nurse who takes care of the same patient for months or years, a friendship is very likely to form.
One concern I have related to caring is that I rarely have tons of time to spend with patients and families, especially since I'm a relatively new nurse, so I'm not a time management pro yet. Sometimes I feel rushed just to meet all of the physical needs, much less to sit down and have much of a caring dialogue.
