I'm an ADN-bound nurse just getting ready to start my final year of school. The whole concept of nursing diagnoses was completely new to me when I started. This system has been very useful to me as a student, and I believe that it will be also when I begin my career as a nurse. It gives me a framework to help me identify the needs of my patient; nursing diagnoses also define the concerns of a nurse. This system carves out our territory.
Years from now when I am experienced I will probably never think about nursing diagnoses. But for the newer nurse, I think it's a great system. BTW, I think "constipation" is an important nursing diagnosis. There are also some very interesting nursing diagnoses, such as "energy field disturbance." This is laughable, but on another level it really isn't. If you think about your patient holistically, this diagnosis may have some validity.
Don't get me wrong -- I HATE writing care plans
and coming up with nursing diagnoses. But I do think this system serves a purpose.
