A nurse is reinforcing teaching with a client who is pregnant and has a prescription for Rho(D) immune globulin. Which of the following information should the nurse include?

Choice D rationale:

The correct answer is Choice D. The biophysical profile is a prenatal test used to assess fetal well-being in the third trimester of pregnancy. It is not used to determine the estimated date of birth (Choice A), as that is typically calculated based on the first day of the last menstrual period and confirmed or adjusted by early ultrasounds.

The test also does not require the client to be NPO (nothing by mouth) for 8 hours prior to the test (Choice B). This restriction is commonly associated with certain medical procedures, but it is not applicable to the biophysical profile.

Furthermore, there is no need to initiate an IV (intravenous line) before the biophysical profile (Choice C). The test is non-invasive and involves the use of ultrasound and fetal heart rate monitoring. The biophysical profile assesses several fetal parameters, such as fetal movement, fetal tone, fetal breathing movements, amniotic fluid volume, and the fetal heart rate. These parameters help evaluate the well-being and health of the baby. The test is often recommended in cases of high-risk pregnancies, decreased fetal movement, or other conditions that may warrant closer monitoring of the baby's condition. By knowing that the biophysical profile predicts fetal well-being in the third trimester, the nurse can provide accurate information to the client, reassuring them about the health of their baby and explaining the importance of the test in ensuring a safe delivery and healthy outcome.

Choice A rationale:

Excessive uterine enlargement. Rationale: The nurse should monitor the client for excessive uterine enlargement, as a hydatidiform mole is a rare condition in pregnancy where abnormal placental tissue forms instead of a fetus. This abnormal growth can lead to uterine enlargement beyond the expected size for gestational age.

Choice B rationale:

Rapidly dropping human chorionic gonadotropin (hCG) levels. Rationale: The nurse should also monitor the client's hCG levels. In a normal pregnancy, hCG levels typically rise steadily during the early stages. However, in the case of a hydatidiform mole, hCG levels may either plateau or drop rapidly due to the abnormal placental growth.

Choice C rationale:

Fetal heart rate irregularities. Rationale: Although a hydatidiform mole does not involve a viable fetus, the nurse should still assess for fetal heart rate irregularities. In some rare cases, the presence of abnormal placental tissue can cause confusion in the diagnosis, and there may be coexisting fetal development. Fetal heart rate irregularities may indicate potential complications.

Choice D rationale:

Whitish vaginal discharge. Rationale: Whitish vaginal discharge is not typically associated with a hydatidiform mole. Instead, this finding is more commonly seen in other vaginal infections or conditions unrelated to a molar pregnancy. The nurse should be cautious not to misinterpret this symptom as a definitive sign of a hydatidiform mole.
