Correct Answer is A
Explanation
A. This test will screen for neural tube defects. MSAFP is a screening tool used to detect neural tube defects (such as spina bifida and anencephaly) in the developing fetus. Elevated levels of AFP are associated with such defects.
B. This test will screen for ABO incompatibility. ABO incompatibility is detected through blood tests, not MSAFP. MSAFP screens for structural abnormalities, not blood group incompatibilities.
C. This test will screen for fetal maturity. MSAFP is not a test for fetal lung maturity. Tests for fetal lung maturity, such as the lecithin-sphingomyelin (L/S) ratio, are typically done later in pregnancy.
D. This test will screen for gestational diabetes. MSAFP is unrelated to gestational diabetes, which is diagnosed with a glucose tolerance test, not MSAFP.
Correct Answer is D
Explanation
A. A high-fiber meal: While fiber is beneficial for preventing constipation, which can occur with iron supplementation, fiber may decrease iron absorption.
B. Milk. Calcium in milk interferes with the absorption of iron and should be avoided when taking ferrous sulfate.
C. Scrambled eggs. Eggs contain phosphates and other compounds that may reduce iron absorption.
D. Orange juice. Vitamin C (found in orange juice) enhances the absorption of iron from supplements and is the best option for improving iron absorption.
