MacBook Pro O Time remaining: 01:59:56 Nursing Kayla Christianson, CMA, has been employed six years by the cardiology practice of three physicians. She is a graduate of a CAAHEP-accredited school. Furthermore, Kayla received extensive hands-on training performing ECGs while doing her required externship. Kayla has completed an ECG ordered by Dr. Hsu for Mrs. Warner, a 76-year-old patient. Dr. Hsu, Kayla’s boss, telephoned her explaining that he was behind schedule doing rounds at the hospital. He asked her to do him a favor and interpret Mrs. Warner’s ECG, sign his name, and fax the report to Mrs. Warner’s referring internist, who is expecting the results. Given the scope of Kayla’s education, training, and years of experience as a CMA, would this “favor” fall within the AAMA guidelines of her responsibilities? Would any portion of Dr. Hsu’s request fall within the guidelines? If so, which portion(s)? Is an exception to these guidelines ever allowed? How should Kayla respond to Dr. Hsu?
