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.
Certifications and Requirements to Become a Nurse Anesthetist Since nurse anesthetists work in patient healthcare, there is extensive training and clinical work involved to enter the profession. Before becoming a nurse anesthetist, candidates typically work in acute care settings (e.g., emergency rooms or intensive care units) as registered nurses (RNs) for at least a year.
