Oh my goodness...honey, listen to me:
It sounds like you work in a hellhole. Every hospital has them. It is not endemic of every job in nursing...far from it. Get your experience, and go to school. Get the tools you'll need to help change it - maybe not on that floor, but somewhere, somehow, within the system.
Does it suck some days? You betcha.
Do I go home in tears sometimes, utterly frustrated? You betcha.
Have I saved countless lives? Yup. Gonna go do it again, tonight.
Have I comforted and educated thousands upon thousands of patients and their families, teaching them how to be well and helping them accept things that aren't going to change? Yup. Gonna go it again, tonight.
Sana: I don't think ANY of us love cleaning up poop and dealing with MRSA and other infectious processes! I know I sure don't, yet I know without a doubt that I am doing what I was meant for in this life.
To dismiss the OP's question in the broader sense based upon a very small section of what the overall scope of care encompasses is not any of us a favor: it discourages her and we don't end up with another potentially valuable member of the profession.
I don't like cleaning up poop, but I love getting them clean, comfortable and smelling nice. I love the results it gets me: lower BP's, fewer arrythmias, less fighting of the vents, SIGNIFICANTLY less agitation in my elderly, and better outcomes all over. Well rested patients = healing patients, and it's part of what we do to help them become well rested.
Angela, consider transferring to a new unit. It sounds like you are getting burned out on your current one. That doesn't mean you're a bad person, bad caregiver, or don't have the potential to be a nurse. It just means you need a new change of scenery. Most nurses work in many different areas throughout their career. It's the beauty of a nursing license: You are portable, and YOU HAVE CHOICES!
Start taking your pre-reqs. Even if you decide against nursing, you will have that many more credits towards a degree of some sort - and a degree is just about manadatory for anything, these days. No education is ever wasted.
Good luck, and let us know if we can help in any way.
