Answer to Question 1

C
Hemophilia is X-linked, so only one parent (the mother) is the carrier. Sickle cell anemia, cystic fibrosis, and Tay-Sachs disease require both parents to be equally contributive, because it is autosomal recessive.

Answer to Question 2

C
One of the adverse responses to methylergonovine is hypertension, so the mother's blood pressure needs to be assessed before and after methylergonovine administration. Assessment of temperature, pulse, and perineum are not assessments specific to the administration of methylergonovine.
