I feel the same way. I am a grad nurse. I am very conscious of what I do, what meds I am giving, etc. I find it difficult deciding when to call the doctor about certain situations. How high or low should a BP be before you notify the doctor.....? When I was preceptoring I did not have the opportunity to call the docor as I was not allowed to take orders. I guess I will learn as time goes on and I become more confident.
