Which role is a master's-trained anesthesia provider working under an anesthesiologist's supervision?

• A. Anesthesiologist Assistant (AA)
• B. Certified Registered Nurse Anesthetist (CRNA)
• C. Anesthesiologist
• D. Surgical Technologist

Answer: (A)

The concept being tested is understanding which anesthesia provider role operates under the direct supervision of an anesthesiologist. Anesthesiologist Assistants are master's-trained professionals who work under the supervision of an anesthesiologist to deliver anesthesia care, including induction, monitoring, and perioperative tasks, under the physician’s direction. The anesthesiologist is the supervising physician, not the one being supervised, and CRNAs commonly practice with varying supervision depending on the setting, often more independently, which doesn’t fit the prompt as clearly. Surgical technologists assist in the operating room but do not administer anesthesia. So, the role that fits the description is the Anesthesiologist Assistant.
