Answer to Question 1

B
Hypoxia can induce arterial vasoconstriction leading to transient pulmonary hypertension. This can lead to blood shunting through an open ductus arteriosus. Because the neonate has been born, the ductus venosus will remain closed. Hypoxia will not cause airway mucosal edema.

Answer to Question 2

C
Approximately 45 of the patient's BSA was burned: head and neck (9), both arms (9  2 = 18), and anterior trunk (18).
