Answer to Question 1

A
Feedback:
A major source of IgA is human breast milk. IgG, found in serum and interstitial fluid, crosses the placenta beginning at approximately 20 to 22 weeks' gestation. IgM is found in blood and lymph fluid and levels are generally low at birth unless there is a congenital intrauterine infection. IgE is not found in breast milk and does not play a major role in defense in the newborn.

Answer to Question 2

A
Feedback:
The fluid status of a pregnant patient with sickle-cell anemia is important because dehydration can precipitate a crisis. The patient should drink at least eight glasses of fluid each day to prevent dehydration. Patients with sickle-cell anemia should not take an iron supplement because the sickled cells cannot incorporate iron in the same way as nonsickled cells. Standing for long periods of time can cause red cell destruction in the patient with sickle-cell anemia. The patient should sit with the legs elevated to encourage venous return of blood from the lower extremities.
