ATI Pediatrics Exam 4 | Nurselytic

Correct Answer: B

Rationale: The correct answer is B: Cardiac Catheterization. Cardiac catheterization provides the most accurate diagnostic picture of a cardiac issue because it involves inserting a catheter into the heart to measure pressures, collect blood samples, and perform imaging tests. This procedure allows direct visualization of the coronary arteries and chambers of the heart, providing detailed information on blockages, valve function, and overall heart function. Echocardiogram (
A) provides valuable information but may not offer the same level of detail as cardiac catheterization. Chest X-Ray (CXR) (
C) provides a basic overview of heart size and lung congestion but lacks the specificity of cardiac catheterization. Electrocardiogram (ECG) (
D) records the heart's electrical activity, giving insight into rhythm disturbances but does not provide the detailed anatomical information that cardiac catheterization does.
