ARDMS (American Registry for Diagnostic Medical Sonography) Practice Test

What is the primary purpose of the echocardiogram?

1. To evaluate blood flow through the arteries

2. To assess the structure and function of the heart

3. To measure blood pressure levels

4. To perform cardiac stress testing

The correct answer is: To assess the structure and function of the heart

The primary purpose of an echocardiogram is to assess the structure and function of the heart. This diagnostic test utilizes ultrasound waves to create images of the heart’s chambers, valves, and surrounding structures, allowing clinicians to observe anatomical abnormalities, measure chamber sizes, and evaluate how well the heart pumps blood. It provides critical information about the heart's health, such as detecting conditions like heart valve disease, cardiomyopathy, and congenital heart defects. While evaluating blood flow through the arteries, measuring blood pressure levels, and conducting cardiac stress testing are important aspects of cardiovascular assessments, they do not represent the main objective of an echocardiogram. These other assessments may utilize different methods and technologies, such as Doppler ultrasound for blood flow evaluation or sphygmomanometers for blood pressure measurement.
