B. examination of the liquor for lamellar bodies.
C. an attempt to measure the fetal scalp pH.
D. an ultrasound examination of the fetus to exclude oesophageal atresia.

An elective caesarean section is being performed at 37 weeks of gestation because of a grade III anterior placenta praevia. The presentation of the baby is cephalic with the head high and mobile. The most appropriate way of effecting delivery is by:
A. classical caesarean section.
B. lower uterine segment caesarean section, incising the placenta and using obstetric forceps.
C. lower uterine segment caesarean section, incising the placenta and guiding the fetal head out manually.
D. lower uterine segment caesarean section, entering the amniotic cavity below the placenta and using obstetric forceps.
E. lower uterine segment caesarean section, entering the amniotic cavity above the placenta and performing internal version and breech extraction.

A multigravid patient is known to have a grossly hydrocephalic baby. She has been in spontaneous labour at 38 weeks for six hours, the cervix is 3 cm dilated and there has been no progress during the last three hours. The appropriate management is:
A. Syntocinon infusion with a view to performing ventriculocentesis when the cervix is at or near full dilatation.
B. transabdominal ventriculocentesis.
C. transvaginal ventriculocentesis.
D. lower uterine segment caesarean section.
E. classical caesarean section.
C - transvaginal ventricuocentesis
A 32 year old woman with a history of two previous normal deliveries is in spontaneous labour at term gestation. The cervix is 5 cm dilated. Intermittent auscultation of the fetal heart rate has suggested decelerations during contractions. Electronic fetal heart rate monitoring has been commenced which reveals variable decelerations down to 80 beats per minutes, lasting 20 seconds, and associated with good baseline variability. The most appropriate action is:
A. perform a scalp pH measurement.
B. administer 500 ml saline intravenously.
C. perform a caesarean section.
D. perform Doppler studies of the umbilical circulation.
E. reposition the patient and continue observation
E - reposition the patient and continue observation
You are about to perform a non-elective caesarean section for failure to progress in a healthy 19 year old primigravida at term. There is no fetal distress. Your anaesthetist is unable to intubate the patient. The best course of action is to:

B. continue using a mask anaesthetic, with the patient on her side and head down.
C. perform a tracheostomy.
D. stop and wait for a regional anaesthetic
E. stop and transfer the patient to a major centre.
?D - stop and wait for a regional anaesthetic
A 24 year old Australian woman, gravida 2, para 1, previously delivered an anencephalic infant. She now is at 8 weeks’ gestation and seeks your advice concerning the possibility of having a second affected infant. You should inform her that the risk of a neural tube defect in the next pregnancy is:
A. less than 0.5%.
B. 1 to 2%.
C. 4 to 5%.
D. 8 to 9%.
E. 12 to 13%.
C - 4-5%
A 19-year-old nulliparous patient with last menstrual period 6 weeks ago presents to the emergency department with sudden onset of pelvic pain and genital spotting. Pelvic examination reveals bilateral adnexal tenderness. Pelvic ultrasound reveals no gestational sac in the uterus. The quantitative serum hCG is 6000 IU. The next appropriate step is:
A. laparotomy.
B. laparoscopy.
C. repeat ultrasound in one week.
D. serial hCG determinations.
E. endocervical culture for Chlamydia.
B - laparoscopy
If the parents of a stillborn fetus with major malformations view the fetus after delivery, the likely outcome is:
A. facilitation of the grieving process.
B. an out-pouring of anger.
C. delay and difficulty with grieving.

E. development of difficulties in their relationship with their existing children.
A - facilitation of the grieving process
