A high prolactin level may result from a pituitary tumor which is releasing too much prolactin. Pituitary tumors are actually fairly common. They are rarely cancerous, but they can cause problems either by over-producing a hormone such as prolactin, or by growing in size and pressing on surrounding structures.
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.
In order to become a nurse anesthetist, you must first complete a Bachelor of Science in Nursing from an accredited school and pass state licensing to become a registered nurse (RN). After a year of professional experience as an RN working in acute medical care - for example in a hospital emergency room or intensive care units - you may apply to earn a Master's of Nursing in Anesthesia.
