A provider is trying to rule out coronary artery disease and wants to examine the patient's blood flow direction and speed. Which of the following cardiology diagnostic procedures should the medical assistant schedule?
A. Transthoracic echocardiogram
B. Transesophageal echocardiogram
C. Doppler ultrasound
D. Cardiac catheterization
Answer (2)
The most appropriate test for examining blood flow direction and speed to rule out coronary artery disease is a Doppler ultrasound, which is non-invasive and specifically designed for measuring blood flow velocity. Other options like echocardiograms focus more on structural views of the heart, while cardiac catheterization is invasive and not primarily for speed measurements. Thus, Doppler ultrasound is the best diagnostic choice in this context.

The best procedure to rule out coronary artery disease while examining blood flow direction and speed is a Doppler ultrasound, which measures blood flow velocity non-invasively. Other options like echocardiograms provide structural information, while cardiac catheterization is more invasive and not primarily focused on blood flow dynamics. Thus, Doppler ultrasound is the preferred diagnostic tool for this purpose. ;
