I felt inferior during college so I do "feel your pain".
I've more than caught up since graduation. It's been 4 years already! I'm also the kind of nurse who takes the time to help student nurses on the floor even during hectic, horrid days. I'll even grab a student when a patient starts to crash. The other night a student wandered onto the floor looking quite embarrassed because her instructer told her she was weak at breath sounds. I took her around to my patients explaing the different breath sounds they have. She was able to listen to BS before and after a neb treatment, listen to rales, rhonchi, wheezes, everything. I remember what it's like...I certainly do.
Don't give up! You'll get there.....
Also the biggest mistakes I saw committed by students were commited by the superior, know- it-all types. If you are at all uncertain about a med, treatment, anything always ask a doc, nurse, pharmacist, drug books, ect. Nothing wrong with that!
