Certified Clinical Medical Assistant CCMA Practice Test

The correct choice pertains to the application of a Holter monitor, which is a portable device used to continuously monitor heart activity over a period of time, usually 24 to 48 hours. This procedure falls well within the scope of practice for a medical assistant, as it involves basic preparation and application of the device on the patient, along with instructions on how to use it during the monitoring period. A medical assistant is trained to perform these tasks without requiring assistance from a licensed technician or provider.

On the other hand, procedures such as echocardiograms, cardiac catheterizations, and pacemaker insertions are more complex and invasive. They require specialized knowledge and skills typically held by trained technicians or healthcare providers. These procedures often involve intricate imaging techniques, direct manipulation within the cardiovascular system, or surgical skills that are beyond the scope of practice for medical assistants. Thus, the Holter monitor application is uniquely suited to be performed by a medical assistant independently.
