  2. A 22yo woman presents at 34/52 gestation in her 1st pregnancy. Her pregnancy appears clinically small for dates. Which of the following is correct?
    A. she could have polyhydramnios
    B. she may have twins.
    C. her dates may have been incorrect
    D. a single ultrasound can determine fetal growth
    E. it would be wise to consider early delivery

  3. Intrauterine growth restriction is associated with:
    a. maternal wt loss in pregnancy
    b. fetal talipes equinovarus
    c. maternal preeclampsia
    d. reduced fetal umbilical artery resistance
    e. all of the above
    • fetal Clubfoot, or talipes equinovarus = developmental deformity of foot
    • - one or both feet are excessively plantar flexed, with the forefoot swung medially and the sole facing inward.
    • - common congenital malformation,
    • - typically discovered at the time ofbirth as an isolated anomaly in an otherwise N neonate.
    • reduced fetal umbilical artery resistance (increased)
    • :. - maternal pre-eclampsia
  4. A 35yo woman w DM is at risk of having:
    a. a macrosomic baby
    b. a growth restricted baby
    c. a traumatic delivery assoc w shoulder dystocia
    d. a baby that succumbs to intrauterine asphyxia
    e. all of the above
  5. Which of the following is correct in the assessment of fetal welbeing?
    a. amniotic fluid volume relects the uterine perfusion and the processes of fetal swallowing, fetal cardiac fn and renal fn
    b. isolated abN fetal umbilical artery Doppler resistance reliably predicts a hypoxaemic fetus
    c. a fetus w a N CTG is likely to be acidotic
    d. the use of fetal scalp sampling for acid-base status in labour has been asooc w an inc in C-section rates
    e. all of the above
    • umbilical artery Doppler resistance - unreliable
    • a fetus w a N CTG is not at risk of acidaemia
    • fetal scalp sampling - evaluation of fetal venous pH and base excess - allows conservative mx- reduce rate of c-sections
    • :. a
  6. Which of the following statements about cerebral palsy are correct?
    a. cerebral palsy occurs in < 5 per 1000 births
    b. about 10% of cases of cerebral palsy may be attributed to intrapartum hypoxia
    c. severe metabolic acidosis in labour should be an essential criterion to diagnose an intrapartum event as causal to cerebral palsy
    d. IUGR may imply a cause of cerebral palsy other than acute intrapartum hypoxia
    e. all of the above
