Does anyone know if there is a statute or rule of a time limit concerning the amount of time lapse between graduation of nursing school and sitting for state boards? I graduated several years ago, have retain most knowledge, taken some pre-requisites that qualify for RN, but want to sit for PN licensure. The pre-req's are very recent, such as: A & P 1-2 with labs, Microbiology + lab. Granted I will have to study hard, but I did not find anything in the state board rules that state I cannot do this. I graduated from a practical nursing program. Please advise, I am ready to study.
