Which of the following cardiac procedures is within the Medical Assistant's (MA) scope of practice?

• A. Angioplasty
• B. Holter Monitor application
• C. Cardiac catheterization
• D. Echocardiogram

Answer: (B)

The Holter monitor application is indeed within the Medical Assistant's scope of practice. This procedure involves attaching a portable device to a patient, allowing for the continuous monitoring of their heart's electrical activity over a specified period, typically 24 to 48 hours. Medical Assistants are trained to properly place the electrodes, instruct the patient on how to wear the monitor, and ensure that recordings are made accurately for subsequent analysis by a healthcare provider.

In contrast, other procedures like angioplasty, cardiac catheterization, and echocardiograms are typically performed by specialized healthcare professionals such as cardiologists or trained technicians. These procedures require advanced training and expertise due to their complexity and the potential risks involved. Thus, only the Holter monitor application aligns with the skills and responsibilities expected of a Medical Assistant in clinical settings.
