A pregnant woman is scheduled to undergo chorionic villus sampling (CVS) based on genetic family history. Which medication does the nurse anticipate will be administered?
- A. Magnesium sulfate
- B. Prostaglandin suppository
- C. RhoGAM if the patient is Rh-negative
- D. Betamethasone
Correct Answer: C
Rationale: The correct answer is C: RhoGAM if the patient is Rh-negative. During CVS, there is a risk of maternal-fetal blood mixing, especially if the patient is Rh-negative. RhoGAM is given to prevent sensitization to the Rh factor, which could lead to hemolytic disease in the newborn. Magnesium sulfate (A) is not indicated for CVS. Prostaglandin suppository (B) is used for cervical ripening or induction of labor, not for CVS. Betamethasone (D) is a corticosteroid given to pregnant women at risk of preterm delivery to promote fetal lung maturation, not indicated for CVS.
