What does CRNA stand for?

• A. Certified Registered Nurse Anesthetist
• B. Certified Registered Nurse Assistant
• C. Certified Registered Nurse Administrator
• D. Certified Radiology Nurse Anesthetist

Answer: (A)

CRNA refers to a nurse who specializes in delivering anesthesia as an advanced practice registered nurse. The correct expansion is Certified Registered Nurse Anesthetist, which communicates three things: the person is certified, is a registered nurse, and specializes in anesthesia. This title is the standard designation used in clinical practice for professionals who administer anesthesia and provide perioperative care, typically after completing graduate-level training and national certification.

The other phrases don’t fit because they describe different roles or credentials that aren’t associated with this anesthesia specialty: a Certified Registered Nurse Assistant would be a CNA, not an RN with anesthesia training; a Certified Registered Nurse Administrator implies an administrative nursing role; and a Certified Radiology Nurse Anesthetist combines radiology with anesthesia, which is not a recognized title or specialty.
