A nurse is caring for a newborn who was recently delivered. Which of the following clinical signs would cause the nurse to suspect tricuspid atresia?
Profound cyanosis
Periorbital edema
Absent femoral pulses
Decreased blood pressure to lower extremities
The Correct Answer is A
A. Profound cyanosis is a key sign of tricuspid atresia, a congenital heart defect where the tricuspid valve is absent, leading to poor oxygenation of the blood.
B. Periorbital edema is not typically associated with tricuspid atresia; it might be seen in other conditions like nephrotic syndrome.
C. Absent femoral pulses suggest coarctation of the aorta rather than tricuspid atresia.
D. Decreased blood pressure in the lower extremities is also more indicative of coarctation of the aorta, not tricuspid atresia.
