Prenatal Care — Flashcards

Flashcard 41: What are the components of the antenatal combined test (first-trimester screening)?_____

Answer: PAPPA + hCG + nuchal translucency

Flashcard 42: A BPP score of _____ is normal

Answer: 8 to 10

Flashcard 43: In a woman with a history of a **previous child with a neural tube defect (NTD)**, _____ mcg of folic acid periconceptionally is given to prevent recurrence in the next child.

Answer: 4000 (4 mg)

Flashcard 44: If a woman receives two doses of Td vaccine in her first pregnancy and a booster in her second pregnancy within 3 years, is another dose required if a third pregnancy occurs within that same 3-year window?

Answer: No (not required)

Extra: This question refers to an older immunization protocol. According to those guidelines, if a woman receives 2 doses of Td (or TT) in her 1st pregnancy and a booster in her 2nd pregnancy within 3 years, a further dose is not strictly required for a 3rd pregnancy occurring within that same 3-year window from the initial doses. **Modern Practice (ACOG/CDC):** A dose of Tdap is recommended in **every** pregnancy (ideally between 27-36 weeks), regardless of the woman's prior immunization history, to maximize transplacental transfer of maternal antibodies to the neonate. **National Immunization Schedule (India):** - Td1: Early in pregnancy. - Td2: 4 weeks after Td1. - Td-Booster: If pregnant within 3 years of receiving 2 doses in a previous pregnancy.

Flashcard 45: A _____reactive NST is said to be a positive result

Answer: non-

Flashcard 46: A reactive Non-Stress Test (NST) is considered a ______ (positive or negative) result.

Answer: Negative (reassuring)

Extra: A reactive NST is a normal finding, indicating fetal well-being (adequate oxygenation). A non-reactive NST is non-reassuring and warrants further evaluation (e.g., Biophysical Profile or Contraction Stress Test).

Flashcard 47: Protein intake should be increased by _____g/day in 3rd trimester

Answer: 30 mins

Flashcard 50: A non-reactive Non-Stress Test (NST) has a low _____

Answer: Positive Predictive Value (PPV)

Extra: The NST is characterized by a high negative predictive value (NPV >99%) but a high false-positive rate (often due to fetal sleep), leading to a low PPV (~10-40%).
