TESTS OF CARDIAC FUNCTION

A newborn with suspected congenital heart disease is admitted to the NICU. The physician orders a test that uses sound waves to visualize blood flow, pressure, and structure of the heart. Which test is this?

b) Echocardiography (2D Echo)

A nurse reviews an echocardiography report. Which finding indicates abnormal blood flow?

c) Turbulence and altered direction of flow

A child undergoes a procedure to evaluate the route of blood flow in the heart and major vessels. Which diagnostic test was performed?

b) Angiography

A pediatric patient presents with respiratory distress. The physician orders a chest X-ray. What is the PRIMARY purpose of this test in cardiac evaluation?

b) Evaluate cardiomegaly and pulmonary vascular markings

A nurse explains to parents that a test will help rule out lung disease and assess heart enlargement. Which test is being described?

b) Chest X-ray

A child has an abnormal heart rhythm detected during screening. Which test is most appropriate to identify electrical abnormalities?

b) ECG

A nurse reminds a student that ECG is not diagnostic for CHD but is still important because it:

c) Identifies abnormal electrical activity requiring further evaluation

A child with suspected metabolic acidosis and possible cardiac condition is evaluated. Which test helps differentiate cardiac from pulmonary causes?

c) ABG

A critically ill child is being monitored for complications like shock and acidosis. Which diagnostic test is MOST useful?

b) ABG

A physician orders the most invasive diagnostic test to evaluate heart valves, function, and structural abnormalities. Which test is this?

c) Cardiac catheterization

During cardiac catheterization, which additional therapeutic procedure may be performed?

b) Angioplasty

A nurse monitors a child after cardiac catheterization. Which complication should be prioritized?

b) Infective endocarditis

After catheterization, the nurse observes swelling and discoloration of the limb used for insertion. What complication is suspected?

b) Circulation changes in catheterized limb

A child is scheduled for cardiac catheterization. Which pre-operative intervention is MOST important?

b) Maintain NPO status

Which diagnostic tests are part of the pre-procedure preparation for cardiac catheterization?

b) ECG, 2D Echo, CBC

A nurse is providing pre-procedure teaching to parents of a child undergoing cardiac catheterization. What is the priority?

a) Explain the procedure and expectations

After cardiac catheterization, which nursing action is MOST important to prevent complications?

b) Keep the affected leg immobilized

The nurse is monitoring vital signs after cardiac catheterization. Why is this important?

a) Detect early complications

Which post-procedure assessment is necessary to evaluate circulation?

b) Assess extremity distal to catheter site

A nurse is checking the insertion site after cardiac catheterization. What is the priority assessment?

b) Bleeding at insertion site
