Questions and Answers

What is the primary reason for performing a vaginal exam as an intervention for late decelerations?

  • To assess cervical dilation (correct)
  • To diagnose a potential placental abruption
  • To reposition the mother on her side
  • To apply oxygen to the fetus

    • What is the significance of the GTPAL notation '4-0-1-2-2' in the context of a twin pregnancy?

  • It indicates four previous pregnancies, zero abortions, one previous cesarean section, and two living children
  • It indicates four previous pregnancies, zero abortions, one set of twins, and two previous cesarean sections
  • It indicates four previous pregnancies, zero abortions, one living child, and two previous cesarean sections (correct)
  • It indicates four previous pregnancies, zero abortions, one previous cesarean section, and two sets of twins

    • What is the primary advantage of CVS over amniocentesis?

  • CVS carries a lower risk of miscarriage
  • CVS can be performed later in pregnancy
  • CVS can be performed earlier in pregnancy (correct)
  • CVS provides more accurate results

    Study Notes

    NST Findings and Interventions

    • Reactive NST indicates a healthy fetal response with appropriate heart rate accelerations.
    • Late decelerations require interventions such as vaginal examination, administering oxygen, and positioning the mother on her side, with calling the healthcare provider as a last resort.

    Prenatal Labs and Procedures

    • Initial prenatal visit should include a full blood count (CBC), rubella immunity check, and RPR/VDLR screening for syphilis.
    • Amniocentesis is performed to collect amniotic fluid, which is essential for detecting genetic abnormalities.

    Fetal Heart Rate Decelerations

    • Fetal heart rate decelerations are classified into three types: late, early, and variable.
    • Each type may indicate different underlying fetal conditions or issues during labor.

    GTPAL System

    • GTPAL stands for Gravida (total pregnancies), Term (term deliveries), Preterm (preterm deliveries), Abortions (spontaneous or elective), and Living children.
    • For one patient with twins, GTPAL is recorded as 4-0-1-2-2.

    Testing Timeline and Profiles

    • Chorionic Villus Sampling (CVS) can be performed earlier in pregnancy compared to amniocentesis, specifically at 16 weeks gestation.
    • A Biophysical Profile evaluates fetal health through measurements of fetal breathing, movement, and amniotic fluid volume, but does not determine the gender of the fetus or neck traversability.

    CST Results

    • A negative contraction stress test (CST) indicates no evidence of uteroplacental insufficiency, suggesting adequate oxygen supply to the fetus.
