A newborn frequently experiences cyanosis, typically during crying or after feeding. Which cardiac diagnosis is supported by this history?
Ventricular septal defect (VSD)
Atrioventricular canal (AVC) defect
Tetralogy of Fallot
Atrial septal defect (ASD) .
The Correct Answer is C
Choice A rationale
A Ventricular septal defect (VSD) is a hole in the wall separating the two lower chambers of the heart. While it can cause cyanosis, it would not typically cause cyanosis only during crying or after feeding.
Choice B rationale
An Atrioventricular canal (AVC) defect is a combination of heart problems resulting in a defect in the center of the heart. While it can cause cyanosis, it would not typically cause cyanosis only during crying or after feeding.
Choice C rationale
Tetralogy of Fallot is a rare condition caused by a combination of four heart defects that are present at birth. These defects, which affect the structure of the heart, cause oxygen-poor blood to flow out of the heart and into the rest of the body. Infants and children with Tetralogy of Fallot usually have blue-tinged skin because their blood doesn’t carry enough oxygen. This is often more noticeable during episodes of crying or feeding.
Choice D rationale
An Atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria). The condition is present at birth (congenital). Small defects might be found by chance and never cause a problem. Some small atrial septal defects close during infancy or early childhood. While it can cause cyanosis, it would not typically cause cyanosis only during crying or after feeding.

Correct Answer is C
Explanation
Choice A rationale
A Ventricular Septal Defect (VSD) is a hole in the wall separating the two lower chambers of the heart. While it can cause cyanosis, it’s typically not associated with cyanosis during crying or feeding.
Choice B rationale
An Atrioventricular Canal (AVC) defect is a combination of heart problems resulting in a defect in the center of the heart. While it can cause cyanosis, it’s typically not associated with cyanosis during crying or feeding.
Choice C rationale
Tetralogy of Fallot is a congenital heart condition characterized by four anatomical abnormalities of the heart. It is the most common cyanotic heart defect and the most common cause of blue baby syndrome. Cyanosis, which is caused by a lack of oxygen in the blood, is often seen during periods of activity, such as feeding or crying.
Choice D rationale
An Atrial Septal Defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria). While it can cause cyanosis, it’s typically not associated with cyanosis during crying or feeding.
Correct Answer is D
Explanation
Choice A rationale
Sinus tachycardia at a rate of 110 beats/min is a normal response to exercise. During a stress test, the heart rate will naturally increase as the body’s demand for oxygen increases. A heart rate of 110 beats/min is within the expected range during moderate exercise.
Choice B rationale
An increase in blood pressure from 134/68 to 150/80 mm Hg is a normal response to exercise. During a stress test, blood pressure will naturally rise as the heart works harder to pump blood to the muscles. This increase is within the expected range during moderate exercise.
Choice C rationale
Feeling tired during a stress test on a treadmill is a normal response to exercise. Fatigue can occur as the body’s energy stores are used up during physical activity. However, if the patient reports extreme fatigue or other symptoms such as chest pain or shortness of breath, it may indicate a problem.
Choice D rationale
Inversion of T waves on the electrocardiogram during a stress test is a sign of myocardial ischemia, a condition in which the heart muscle is not getting enough oxygen. This could indicate the presence of significant coronary artery disease and is a finding that would necessitate immediate action.
