Answer to Question 1

ANS: C, D
Coumadin is monitored using the PT and INR. Electrolytes and hematocrit are important laboratory values but are not specific for this drug. The PTT is used to monitor heparin therapy.

Answer to Question 2

ANS: B, C, D
Guidelines for who needs prophylaxis prior to invasive procedures were updated in 2007. They include children post-cardiac transplantation who do not have residual valve problems for 6 months post-transplant, any child with a residual defect after a surgical repair for the remainder of his or her life, and children who have already had one (or more) episode of BE. Prophylaxis after complete repairs is for 6 months. Prophylaxis after valve replacement is lifelong.
