Answer to Question 1

B
In the normal neonate, fetal shunts functionally close in response to pressure changes in the systemic and pulmonary circulations and to increased oxygen content. This process may take several days to complete. With the neonate's first breath, gas exchange is transferred from the placenta to the lungs. The separation of the fetus from the umbilical cord does not contribute to the establishment of neonatal circulation.

Answer to Question 2

B
The standard prophylactic agent is amoxicillin given orally 1 hour before the procedure. Antibiotic prophylaxis is indicated for the first 6 months after surgical repair. Antibiotic prophylaxis is not given for this period of time. The treatment for infective endocarditis involves parenteral antibiotics for 4 to 8 weeks.
