A nurse is teaching a patient who is 15 weeks pregnant and is to undergo an amniocentesis.

The nurse should explain that the purpose of this test is to identify which of the following conditions? (Select all that apply.)

Choice A rationale
An irregular fetal heart rate is not a typical finding in a hydatidiform mole. In a complete molar pregnancy, no embryo forms, and thus, there would be no fetal heart rate to measure.
Choice B rationale
While vaginal discharge can occur in a molar pregnancy, it is typically described as brownish or bloody, not clear.
Choice C rationale
Excessive uterine enlargement is a common symptom of a hydatidiform mole. This occurs because the abnormal placental tissue grows rapidly, which can cause the uterus to expand more quickly than it would in a normal pregnancy.
Choice D rationale
In a molar pregnancy, human chorionic gonadotropin (hCG) levels typically rise more rapidly than they would in a normal pregnancy, not decline rapidly.

Choice A rationale
Abstaining from all alcohol consumption is a key recommendation for a healthy pregnancy. Alcohol can cause a range of developmental problems in the fetus, including fetal alcohol syndrome. Therefore, it’s best to avoid alcohol entirely during pregnancy.
Choice B rationale
Maintaining a nutritious diet rich in fruits and vegetables is essential for a healthy pregnancy. A balanced diet ensures that the mother and baby get the necessary nutrients for healthy growth and development.
Choice C rationale
Ceasing smoking immediately is another important recommendation for a healthy pregnancy. Smoking during pregnancy can lead to a variety of health problems for the baby, including premature birth, low birth weight, and sudden infant death syndrome.
Choice D rationale
Incorporating cardiovascular exercises into her workout routine is beneficial during pregnancy. Regular, moderate-intensity exercise can help manage weight gain, improve mood, and reduce pregnancy-related discomforts such as back pain and fatigue.
