Answer to Question 1

ANS: A
Protective levels of antibody are maintained for at least 10 years. Children with serious tetanus-prone wounds, including contaminated, crush, puncture, or burn wounds, should receive a tetanus toxoid booster prophylactically as soon as possible. This adolescent has circulating antibodies. The immunoglobulin is not indicated.

Answer to Question 2

ANS: D
The goal is to prevent isoimmunization. If the mother has not been previously exposed to the Rh-negative antigen, Rh immunoglobulin (RhIg) is administered at 26 to 28 weeks of gestation and again within 72 hours of birth. The intramuscular administration of RhIg has virtually eliminated hemolytic disease of the infant secondary to the Rh factor. Unless other problems coexist, the newborn will not require transfusions at birth.
