Why Obstetrics & Gynaecology matters in AMC MCQ

Obstetrics & Gynaecology contributes 10–12 questions to AMC MCQ, covering antenatal care milestones, ectopic pregnancy, postpartum haemorrhage, pre-eclampsia, gestational diabetes, contraception choice, abnormal uterine bleeding, menopause, and gynaecological cancer screening under the National Cervical Screening Program (NCSP).

Mostly Medicine’s O&G bank is mapped to the RANZCOG clinical guidelines, RACGP’s antenatal handbook, the Australian Pregnancy Care Guidelines, and Therapeutic Guidelines: Obstetrics & Gynaecology. You’ll see items on first-trimester screening pathways (combined first-trimester screening vs NIPT), gestational diabetes diagnosis (75 g OGTT thresholds at 24–28 weeks), magnesium sulphate for severe pre-eclampsia, anti-D prophylaxis, the LARC-first contraception philosophy, and the 5-yearly HPV-based NCSP.

AMC O&G vignettes commonly bundle a positive β-hCG with vital signs, ultrasound findings and Rh status, then ask for the most appropriate next investigation or management.

5 free Obstetrics & Gynaecology sample MCQs

Below are five sample questions taken straight from the Mostly Medicine obstetrics & gynaecology bank. The correct answer is highlighted, with the worked explanation tucked inside a collapsed panel so you can self-test first.

Question 1Ectopic Pregnancy · easy

A 28-year-old woman presents with 6 weeks amenorrhoea, lower abdominal pain and light vaginal bleeding. BP 90/60, HR 120, urine hCG positive. What is the MOST appropriate immediate step?

  1. A.Transvaginal ultrasound and discharge if scan normal
  2. B.IV access, fluids, urgent gynaecology review✓ Correct
  3. C.IM methotrexate
  4. D.Serum quantitative hCG and review in 48 hours
  5. E.Oral analgesia and pelvic rest
+Show explanation

Haemodynamically unstable with positive hCG = ruptured ectopic until proven otherwise. This is a surgical emergency. Immediate IV access, fluids, and urgent gynaecology referral/theatre. Methotrexate is for stable, unruptured ectopic.

Question 2Cervical Cancer Screening · easy

According to RACGP Red Book, when should cervical screening commence and at what interval for an average-risk Australian woman?

  1. A.Age 18, annually
  2. B.Age 21, every 2 years (Pap smear)
  3. C.Age 25, every 5 years (HPV test)✓ Correct
  4. D.Age 25, every 2 years (HPV test)
  5. E.Age 18, every 5 years (HPV test)
+Show explanation

Australia updated to HPV-based cervical screening in 2017. Cervical Screening Test starts at age 25 and is done every 5 years until age 74. No co-test needed. Replaced the 2-yearly Pap smear program.

Question 3Ectopic Pregnancy · easy

A 28-year-old woman presents with 6 weeks amenorrhoea, LIF pain, and PV spotting. BP 90/60, HR 118. Urine hCG positive. USS shows no intrauterine pregnancy, 4 cm adnexal mass, and free fluid in POD. What is the diagnosis and management?

  1. A.Threatened miscarriage — bed rest and serial hCG
  2. B.Ruptured ectopic pregnancy — immediate surgical management✓ Correct
  3. C.Ovarian cyst rupture — laparoscopy electively
  4. D.Methotrexate for medical management
  5. E.IV fluids and observation for 24 hours
+Show explanation

Ruptured ectopic pregnancy: haemodynamic instability + positive hCG + empty uterus + adnexal mass + haemoperitoneum. Life-threatening emergency. Immediate resuscitation + emergency surgery (laparoscopy or laparotomy depending on stability). Methotrexate only for unruptured, haemodynamically stable, small ectopic (<3.5 cm), no fetal heartbeat, hCG <5000 IU/L. Anti-D if Rh negative.

Question 4Pre-eclampsia · hard

A 32-year-old primigravida at 34 weeks presents with BP 158/105, headache, epigastric pain, and 3+ proteinuria on dipstick. Platelet count 88 × 10⁹/L, ALT 210 U/L, creatinine 110 µmol/L. What is the diagnosis?

  1. A.Gestational hypertension
  2. B.Pre-eclampsia with severe features
  3. C.HELLP syndrome✓ Correct
  4. D.Acute fatty liver of pregnancy
  5. E.Chronic hypertension with superimposed pre-eclampsia
+Show explanation

HELLP syndrome: Haemolysis (↑LDH, ↓Hb), Elevated Liver enzymes (↑ALT), Low Platelets (<100 × 10⁹/L). Severe form of pre-eclampsia. Features: epigastric/RUQ pain, nausea, hypertension. Fetal and maternal emergency. Management: stabilise, corticosteroids for fetal lung maturity if <34 weeks, definitive treatment = delivery. MgSO4 for seizure prophylaxis.

Question 5Gestational Diabetes · hard

A 34-year-old woman at 26 weeks gestation has an OGTT result: fasting glucose 5.3 mmol/L, 1-hour 11.5 mmol/L, 2-hour 9.2 mmol/L. What is the diagnosis (ADIPS 2014 criteria) and initial management?

  1. A.Normal OGTT — no action
  2. B.GDM — dietary modification + monitoring, insulin if targets not met✓ Correct
  3. C.Type 2 DM in pregnancy — immediate insulin
  4. D.GDM — metformin first-line
  5. E.Impaired fasting glucose only — retest at 36 weeks
+Show explanation

GDM (ADIPS 2014): fasting ≥5.1, 1h ≥10.0, 2h ≥8.5 (any ONE met = GDM). This patient meets 1h criterion (11.5≥10). Initial management: medical nutrition therapy (MNT) + blood glucose monitoring (BGL targets: fasting <5.0, 1h post-meal <7.4, 2h <6.7). Insulin if targets not met within 1–2 weeks. Metformin can be used but placental transfer — insulin preferred.

Obstetrics & Gynaecology FAQ

How is ectopic pregnancy tested?

Expect vignettes mixing positive β-hCG with PV bleeding and pelvic pain, then asking when to choose methotrexate versus laparoscopic salpingectomy/salpingostomy. Know that haemodynamic instability mandates surgery, not medical management.

What antenatal screening should I know?

Routine bloods at booking (FBE, blood group + antibody screen, rubella, syphilis, HIV, hepatitis B, hepatitis C), 11–13+6 week combined first-trimester screening or NIPT, 18–20 week morphology scan, and 24–28 week 75 g OGTT and FBE.

How is pre-eclampsia managed?

BP ≥140/90 with proteinuria or end-organ involvement after 20 weeks. Severe disease (BP ≥160/110, neurological symptoms) requires magnesium sulphate, antihypertensive (labetalol, hydralazine, nifedipine), and timely delivery.

What is the current cervical screening program?

The National Cervical Screening Program offers a 5-yearly HPV-based test from age 25 to 74, replacing the 2-yearly Pap smear since 2017. Self-collection has been universally available since 2022.
