In vitro fertilization-embryo transfer (IVF-ET) is a common approach for women with blocked fallopian tubes or unexplained infertility and for men with very low sperm counts. A husband and wife have arrived for their preprocedural interview. The husband asks the nurse to explain what the procedure entails. The nurse's most appropriate response is:

Choice A reason: Amniocentesis for fetal lung maturity is not an expected diagnostic procedure for a pregnant woman with bright red, painless vaginal bleeding. It is a procedure that involves inserting a needle into the amniotic sac to obtain a sample of amniotic fluid, which can be used to assess the fetal lung development. It is usually done in late pregnancy or preterm labor, not in the second trimester.

Choice B reason: Contraction stress test (CST) is not an expected diagnostic procedure for a pregnant woman with bright red, painless vaginal bleeding. It is a test that involves stimulating uterine contractions, either by nipple stimulation or oxytocin infusion, to evaluate the fetal heart rate response. It is used to assess fetal well-being and placental function, not to diagnose the cause of bleeding.

Choice C reason: Internal fetal monitoring is not an expected diagnostic procedure for a pregnant woman with bright red, painless vaginal bleeding. It is a method of measuring the fetal heart rate and uterine contractions using electrodes or catheters that are inserted through the cervix and attached to the fetal scalp or the amniotic sac. It is usually done during labor, not in the second trimester.

Choice D reason: Ultrasound for placental location is an expected diagnostic procedure for a pregnant woman with bright red, painless vaginal bleeding. It is a test that uses sound waves to create an image of the uterus, the placenta, and the fetus. It can help to determine the position and attachment of the placenta, which can be the cause of bleeding if it is low-lying or covering the cervix (placenta previa).

Choice E reason: None of the above is not a correct answer. There is one expected diagnostic procedure for a pregnant woman with bright red, painless vaginal bleeding, which is ultrasound for placental location.

Choice A reason: Eating three larger meals a day is not recommended for hyperemesis gravidarum, as it may increase the nausea and vomiting. Instead, the nurse should advise the woman to eat small, frequent meals throughout the day.

Choice B reason: Ice cream may stay down better than other foods, as it is cold, bland, and soothing. The nurse should encourage the woman to try foods that are appealing to her and avoid foods that trigger nausea.

Choice C reason: Eating what sounds good to the woman even if her meals are not well-balanced is acceptable for hyperemesis gravidarum, as the priority is to maintain hydration and nutrition. The nurse should reassure the woman that she can resume a balanced diet once her symptoms improve.

Choice D reason: Avoiding ginger tea or sweet drinks is not necessary for hyperemesis gravidarum, as some women may find them helpful in reducing nausea. The nurse should suggest the woman to experiment with different beverages and see what works for her.

Choice E reason: Eating a high-protein snack at bedtime is beneficial for hyperemesis gravidarum, as it can prevent low blood sugar levels and morning sickness. The nurse should recommend the woman to have a protein-rich food, such as cheese, yogurt, nuts, or eggs, before going to bed.
