A nurse is caring for a client who is postpartum.
Which of the following findings is an indication for the nurse to administer Rho(D) immune globulin?

Choice A rationale:

Has mitral valve insufficiency. This client's medical condition is not an indication for an amniotic fluid alpha-fetoprotein screening. Alpha-fetoprotein screening is typically used to assess the risk of neural tube defects and chromosomal abnormalities in the fetus. Mitral valve insufficiency is unrelated to this screening.

Choice B rationale:

History of preterm labor. A history of preterm labor is not a direct indication for amniotic fluid alpha-fetoprotein screening. This screening is primarily used to detect neural tube defects and chromosomal abnormalities in the fetus. Preterm labor history is not related to these conditions.

Choice C rationale:

History of delivering a child with a neural tube defect. This is the correct choice. A history of delivering a child with a neural tube defect is a strong indication for amniotic fluid alpha-fetoprotein screening. The screening is used to assess the risk of neural tube defects in subsequent pregnancies. It is crucial for early detection and management if the risk is high.

Choice D rationale:

Has been exposed to AIDS. Exposure to AIDS (HIV) is not a direct indication for amniotic fluid alpha-fetoprotein screening. This screening is primarily focused on assessing fetal health and the risk of specific congenital abnormalities. HIV exposure is unrelated to the purpose of this screening.

Choice A rationale:

Abdominal pain with minimal red vaginal bleeding is more suggestive of abruptio placentae rather than placenta previa. Placenta previa is characterized by painless vaginal bleeding, and the absence of pain is a key distinguishing factor in its diagnosis. Therefore, this finding does not align with the typical presentation of placenta previa.

Choice B rationale:

Severe abdominal pain with increasing fundal height is not consistent with the typical presentation of placenta previa. Placenta previa is generally associated with painless vaginal bleeding, and fundal height measurements are not typically used to diagnose placenta previa. This finding suggests a different condition, such as abruptio placentae, which involves painful bleeding with a rising fundal height.

Choice D rationale:

Intermittent abdominal pain following the passage of bloody mucus is more characteristic of preterm labor or other conditions, not placenta previa. Placenta previa is primarily associated with painless, bright red vaginal bleeding without contractions or pain. Therefore, this finding does not align with the typical presentation of placenta previa.
