Question

1. the study that uses ultrasound to determine the velocity of the flow of blood within a vessel is:

○ cardiac scan
○ cardiac catheterization
○ treadmill stress test
○ doppler flow studies

1. the medical term cardiology means:

○ physician who studies and treats disease of the heart
○ the science and study of the heart
○ pertaining to the heart
○ physician who studies and treats diseases of the blood

Explanation:

Question 35

• Cardiac Scan: Generally used to visualize the heart's structure, not specifically for blood flow velocity via ultrasound.
• Cardiac Catheterization: Involves inserting a catheter into the heart, not using ultrasound for blood flow velocity.
• Treadmill Stress Test: Assesses heart function during exercise, not for blood flow velocity with ultrasound.
• Doppler Flow Studies: Uses Doppler ultrasound to measure blood flow velocity in vessels.

• "physician who studies and treats disease of the heart" describes a cardiologist, not cardiology.
• "the science and study of the heart" is the definition of cardiology (from the root "cardio-" meaning heart and "-ology" meaning study of).
• "pertaining to the heart" is the meaning of "cardiac", not cardiology.
• "physician who studies and treats diseases of the blood" describes a hematologist, not related to cardiology.

Answer:

D. Doppler Flow Studies
