The nurse should include the following statement in patient teaching: 2) 'This test allows the radiologist to examine the function of your heart valves.'
A cardiac ultrasound, also known as an echocardiogram, uses sound waves to create images of the heart.

By visualizing the heart valves, the doctor can determine if they are functioning properly or if there is any abnormality in their structure or function.
