A high prolactin level may result from a pituitary tumor which is releasing too much prolactin. Pituitary tumors are actually fairly common.

Upon completion of an accredited program, nurse anesthetists must pass the National Certification Examination (NCE) to become a CRNA. This computer exam typically takes three hours. Each student must answer between 100 and 170 questions.
Once licensed as an RN, one must have at least one year of nursing experience before gaining admission into a graduate nurse anesthetist graduate program, according to the AANA. Most nurse anesthetist graduate programs take two or three years to complete.
