Absolutely. You are going to be a terrible nurse, drop out immediately!
No!!! This is a very reasonable fear. Those who are cautious are the ones least-likely to make mistakes. All of us have worried that we will drop someone, or do something wrong, hurt a patient, but that all eases with practice and time. I am working in the CCU tonight, its my first night there, and I am a little worried, but I know that as long as I am cautious, keep my ears and eyes open, everything will work out. Fears are very natural, and motivate us to be better, and be more careful. You will be fine!!! And yes, everything in life takes practice to gain confidence. When I was a CNA, I lifted a patient incorrectly, and almost slid them clean off the bed! Luckily, My legs are strong, so I could correct what my arms were lacking (my arms are quite a bit stronger now than they were then). It cared the CRAP out of me!!! But, it made me MUCH more cautious, and i never forget to check and make sure the wheels of the bed are locked now. it just takes time
Relax, be sharp, and you will be an excellent nurse
