Based on the high-yield topics in your prediction table (Endometriosis, Fibroids, Hysteroscopy, Müllerian anomalies, Malpresentation, Anticoagulation in pregnancy, PPH, Pre-eclampsia/HELLP, AFE, and Ectopic pregnancy), here are 10 NEET PG-level questions built as close differential traps, each with two deliberately confusing options.
Q1. Endometriosis vs Adenomyosis
A 34-year-old multipara presents with worsening secondary dysmenorrhea and menorrhagia. Uterus is bulky, globular, and diffusely tender on bimanual exam. MRI shows junctional zone thickening >12 mm with T2-hyperintense foci within the myometrium; no discrete mass distorts the uterine contour.
A. Endometriosis with chocolate cyst
B. Adenomyosis
C. Intramural leiomyoma
D. Endometrial carcinoma
Answer: B – Adenomyosis. The diffuse junctional zone widening with myometrial T2-hyperintense foci (not a discrete encapsulated mass) is the classic MRI signature. A is confusing because it also causes dysmenorrhea and can coexist, but it doesn't produce a diffusely bulky uterus with junctional zone change. C is confusing because fibroids also cause bulky uterus, but they present as well-defined masses that distort the contour, not diffuse infiltration.
Q2. Fibroid complication in pregnancy
A pregnant woman at 28 weeks with a known large anterior wall fibroid develops acute, severe, localized abdominal pain with low-grade fever and tenderness directly over the fibroid. No bleeding, no fetal distress. USG shows internal heterogeneous degeneration within the fibroid.
A. Emergency myomectomy
B. Conservative management with analgesics, hydration, and rest
C. Immediate hysterectomy
D. Emergency lower segment cesarean section
Answer: B. This is classic red (carneous) degeneration of a fibroid in pregnancy, self-limiting and managed conservatively. A and C are the confusing traps because surgery on a gravid uterus (myomectomy or hysterectomy) risks catastrophic hemorrhage and pregnancy loss and is avoided unless there is torsion of a pedunculated fibroid or failure of conservative treatment.
Q3. Hysteroscopy complication
During hysteroscopic myomectomy using 1.5% glycine as distension medium, the fluid deficit reaches 2800 mL. The patient becomes confused and then has a seizure; labs show serum sodium of 118 mEq/L.
A. Uterine perforation with intraperitoneal fluid collection
B. Dilutional hyponatremia / fluid overload syndrome (TURP-like syndrome)
C. Anaphylactic reaction to glycine
D. Venous air embolism
Answer: B. Hypotonic, electrolyte-free media like glycine absorbed systemically beyond the safe deficit threshold (~1000-1500 mL) causes dilutional hyponatremia and cerebral edema, identical to TURP syndrome. Immediate step is stopping the procedure, fluid restriction, and hypertonic saline if severe. A is confusing because perforation also causes excess fluid absorption and must be excluded, but it doesn't independently explain the hyponatremia pattern. C is confusing because glycine reactions exist, but there's no rash/bronchospasm here.
Q4. Müllerian anomaly
A woman with recurrent first-trimester miscarriages undergoes 3D USG showing two separate endometrial cavities with a fundal indentation depth of 0.8 cm, but the external fundal contour is smooth and convex.
A. Bicornuate uterus — abdominal metroplasty (Strassman procedure)
B. Septate uterus — hysteroscopic septal resection
C. Arcuate uterus — no treatment required
D. Uterine didelphys — two cervices present
Answer: B. A normal (convex/flat) external fundal contour with internal cavity division points to a septate uterus, best treated by hysteroscopic metroplasty. A is the key confusing distractor because bicornuate uterus also has two cavities and recurrent loss, but it shows an indented/notched external fundal contour requiring abdominal surgery, not hysteroscopy. C is confusing because arcuate is a mild variant, but the depth and clinical impact described here exceed arcuate criteria - Berek & Novak's Gynecology, Congenital Anomalies of the Uterus.
Q5. Persistent Occipito-Posterior position
Primigravida in second stage of labour, fully dilated, vertex at +2 station, occiput persistently posterior, adequate pelvis, epidural in situ, no fetal distress.
A. Attempt manual rotation to occipito-anterior, then proceed to vaginal delivery
B. Rotational (Kielland) forceps directly in the OP position
C. Proceed immediately to cesarean section
D. Direct vacuum (ventouse) application without rotation
Answer: A. Manual rotation is the first-line, least invasive step with adequate pelvis and no distress. B is confusing because rotational forceps is a valid escalation if manual rotation fails, but it carries higher maternal/fetal trauma risk and is not the first step. C is confusing because cesarean is reserved for failed rotation/instrumental attempts, not the initial approach in a favorable scenario like this.
Q6. High-risk pregnancy on anticoagulation
A 28-year-old with a mechanical mitral valve on maintenance warfarin confirms pregnancy at 5 weeks.
A. Continue warfarin throughout pregnancy at the same dose
B. Switch to dose-adjusted, monitored therapeutic LMWH during weeks 6-12, resume warfarin in 2nd/3rd trimester, then switch back to LMWH/UFH near term
C. Switch to unfractionated heparin infusion for the entire pregnancy
D. Stop all anticoagulation during the first trimester
Answer: B, per ACC/AHA and ESC guidance. A is confusing because warfarin is effective at preventing valve thrombosis, but it is teratogenic (embryopathy) between weeks 6-12. C is confusing because UFH is a genuine alternative throughout pregnancy, but it carries a higher failure rate for valve thrombosis than adequately monitored LMWH and is reserved for those without access to anti-Xa monitoring.
Q7. Postpartum Hemorrhage - stepwise management
Atonic PPH persists despite oxytocin, methylergometrine, and carboprost, with bimanual compression applied. Patient is hemodynamically stable and desires fertility preservation.
A. Uterine artery embolization (UAE)
B. Intrauterine (Bakri) balloon tamponade
C. B-Lynch compression suture
D. Emergency hysterectomy
Answer: B. In the standard FIGO/RCOG stepwise algorithm, bedside uterine tamponade is the first conservative surgical step before escalating to interventional radiology or laparotomy. A is confusing because UAE is genuinely appropriate in a stable patient with IR access, but it typically follows failed tamponade. C is confusing because B-Lynch is also fertility-sparing and effective, but it requires laparotomy and is generally reserved for cases already in theatre or after balloon failure.
Q8. Severe Pre-eclampsia/HELLP - Magnesium toxicity
A woman on MgSO4 infusion for severe pre-eclampsia now has absent patellar reflexes and a respiratory rate of 10/min; urine output is adequate.
A. Continue infusion; absent reflexes are an expected therapeutic effect
B. Stop the infusion and give IV calcium gluconate (10 mL of 10%)
C. Stop the infusion and give IV calcium chloride instead
D. Continue infusion at half the rate
Answer: B. Loss of deep tendon reflexes plus respiratory depression signals magnesium toxicity requiring immediate cessation and calcium gluconate as the standard antidote. A is a dangerous confusing option since mild hyporeflexia can occur therapeutically, but absent reflexes with respiratory depression is frank toxicity, not an expected finding. C is confusing because calcium chloride also supplies calcium, but calcium gluconate is preferred (lower tissue necrosis risk on extravasation) and is the textbook answer.
Q9. Amniotic Fluid Embolism
During active labour, a woman suddenly collapses with acute hypoxia and hypotension, progresses to cardiac arrest, and is then found to have severe DIC with massive hemorrhage. No preceding calf swelling or chest pain.
A. Pulmonary thromboembolism
B. Amniotic fluid embolism
C. Anaphylactic/drug reaction
D. Septic shock
Answer: B. AFE is a clinical diagnosis of exclusion characterized by this classic biphasic pattern: sudden cardiorespiratory collapse followed by consumptive coagulopathy/hemorrhage; there is no confirmatory lab test. A is confusing since PE is the top differential for sudden peripartum collapse, but it typically has risk factors (immobility, calf swelling) and doesn't inherently trigger DIC as an early feature. C is confusing because the acute collapse mimics anaphylaxis (leading to the term "anaphylactoid syndrome of pregnancy" for AFE), but there's no allergen exposure or urticaria described here.
Q10. Ectopic Pregnancy - Medical vs Surgical management
Transvaginal USG confirms an unruptured tubal ectopic, mass size 3 cm, no fetal cardiac activity. Serum beta-hCG is 4500 mIU/mL. Patient is hemodynamically stable with no contraindications to methotrexate.
A. MTX is not indicated; hCG above 3000 mandates surgery
B. Single-dose IM Methotrexate is appropriate
C. MTX is contraindicated because mass size exceeds 2 cm
D. Immediate salpingectomy is the only correct option
Answer: B. This patient meets standard single-dose MTX eligibility: hCG <5000 mIU/mL, mass <3.5-4 cm, no cardiac activity, hemodynamically stable, no contraindications - Berek & Novak's Gynecology, Medical Treatment of Ectopic Pregnancy. A is confusing because some learners misremember the cutoff as 3000; the actual accepted threshold for good single-dose success is <5000. C is confusing because it misapplies the size cutoff (the real threshold is closer to 3.5-4 cm, not 2 cm).
