Correct Answer is C

Explanation

A. The A1c test measures the average blood glucose levels over the past 2-3 months, not the liver’s ability to absorb hemoglobin.

B. The A1c test does not provide current glucose levels in the blood but reflects long-term glucose control.

C. An A1c of 46% (6.5%) is a generally accepted target for good diabetic control, reflecting long-term blood glucose levels.

D. An A1c test is typically done every 3 months for people with diabetes, not routinely between 24 to 28 weeks in all pregnant women unless they have diabetes.

A. Genetic testing when the babies are delivered will need to be done to determine this. B. They are dizygotic because the ultrasound shows one is bigger than the other. C. The twins are dizygotic because they are not the same sex D. They are monozygotic because they are in different amniotic sacs.

Correct Answer is C

Explanation

A. Genetic testing is not necessary to determine if the twins are identical. Identical twins come from the same egg, while fraternal twins come from separate eggs.

B. The size difference alone does not determine whether twins are identical or fraternal.

C. Dizygotic twins (fraternal twins) are always of different sexes. This is because they are fertilized by two separate sperm and develop from two separate eggs.

D. Monozygotic twins (identical twins) occur when one fertilized egg splits into two embryos. The fact that they are different sexes rules out the possibility of monozygotic twins.
