Which diagnostic procedure involves a catheter passed into a vein or artery and guided into the heart?

• A. Emesis
• B. Dyspepsia
• C. Cardiac catheterization
• D. Cardiomyopathy

Answer: (C)

This question tests understanding of a procedure in which a thin catheter is inserted into a vein or artery and guided into the heart to assess its function and anatomy. That description matches cardiac catheterization. Through this approach, clinicians can measure intracardiac pressures, sample blood, and use contrast dye to image the coronary arteries via angiography, helping diagnose conditions like coronary artery disease, valve problems, or congenital heart defects. The other options are not procedures: vomiting and indigestion are symptoms, and a cardiomyopathy is a heart muscle disease, not a diagnostic technique.
