Answer to Question 1

C
When patients develop antibodies against factor VIII, activated factor VII is used, because it has the same actions as factor VIII. Patients with severe hemophilia A have a 20 to 30 likelihood of developing antibodies to factor VIII and the risk of inhibitor development is unusually high in African American and Hispanic patients, so this patient has an increased risk. Factor VIIa is not stronger than factor VIII. It is not used for prophylaxis only. Immune tolerance therapy describes the use of repeated administration of factor replacement products to eliminate inhibitor produc-tion.

Answer to Question 2

B
Children who weigh less than 50 kg should use 1 spray in one nostril for a dose of 150 mcg. Each spray delivers 150 mcg, so 1 spray in both nostrils would give a dose of 300 mcg. Using 2 sprays in one nostril would give a dose of 300 mcg; using 2 sprays in both nostrils would give a dose of 600 mcg.
