Which term is a physician who specializes in diseases of the blood?

• A. HEMATOLOGIST
• B. ELECTROCARDIOGRAM
• C. CARDIAC CATHETERIZATION
• D. VENIPUNCTURIST

Answer: (A)

The main idea is recognizing medical specialty terms based on their roots. For diseases of the blood, the physician is a hematologist. The root hemat/o means blood, and the suffix -logist means a specialist or one who studies. So a hematologist is the doctor who focuses on blood disorders like anemia, leukemia, and clotting problems. The other options point to something different: an electrocardiogram is a test of the heart’s electrical activity; cardiac catheterization is a procedure to examine heart vessels and function; venipuncturist refers to someone who draws blood, not a physician who specializes in blood diseases.
