This page is dedicated to organizing various examples of standardized exam questions whose answer is transposition of the great vessels. While this may seem a odd practice, it is useful to see multiple examples of how transposition of the great vessels will be characterized on standardized exams (namely the boards and the shelf exams). This page is not meant to be used as a tradition question bank (as all of the answers will be the same), however seeing the classic “test” characterization for a disease is quite valuable.
Question # 1
A 3 hour old boy continues to develop worsening cyanosis over the past few minutes. This child was delivered vaginally at 39 weeks gestation without any complications. The prepartum course was also uncomplicated. The child’s weight was 8.5 lbs, and Apgars were 7 and 8. Supplemental oxygen is administered however it does not receive the cyanosis. Further examination demonstrates tachypnea, subcostal retractions, normal S1, a single loud S2, and no murmur. What could explain this child’s cyanosis?
