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. Practising 150+ Australian-aligned O&G MCQs is the fastest path to fluency. Sign up free to unlock the full bank with explanations.

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 reviewCorrect
  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 managementCorrect
  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 syndromeCorrect
  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 metCorrect
  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.
