A Perinatal Nurse Is Giving Discharge Instructions to a Woman,status

A perinatal nurse is giving discharge instructions to a woman,status post suction and curettage secondary to a hydatidiform mole.The woman asks why she must take oral contraceptives for the next 12 months.The best response from the nurse is:

A) "If you get pregnant within 1 year,the chance of a successful pregnancy is very small.Therefore,if you desire a future pregnancy,it would be better for you to use the most reliable method of contraception available."
B) "The major risk to you after a molar pregnancy is a type of cancer that can be diagnosed only by measuring the same hormone that your body produces during pregnancy.If you were to get pregnant,it would make the diagnosis of this cancer more difficult."
C) "If you can avoid a pregnancy for the next year,the chance of developing a second molar pregnancy is rare.Therefore,to improve your chance of a successful pregnancy,it is better not to get pregnant at this time."
D) "Oral contraceptives are the only form of birth control that will prevent a recurrence of a molar pregnancy."
