Arab Board Ob/Gyn Final Written common mistakes

Arab Board Ob/Gyn Final Written · Understand the traps and how to avoid them.

Mistake 1

When the stem asks for the next step in management of a postpartum haemorrhage that has not responded to oxytocin and ergometrine, the candidate selects hysterectomy or uterine artery embolisation rather than the immediate next bedside action (bimanual compression, tranexamic acid, balloon tamponade, and escalation to theatre).

The candidate pattern-matches the word 'haemorrhage' to the definitive rescue option and answers 'what eventually fixes this' rather than 'what do I do now'; the algorithm is memorised as a list, not as an ordered sequence.

What to do instead

Before answering any 'next step' item, write the four or five steps of the local protocol in order in the margin and select the earliest step not yet done in the stem. Train on stems that deliberately include a late option first so the sequencing habit becomes automatic.

Mistake 2

The candidate recommends delivery for every woman with preeclampsia, including a 33-week gestation with new hypertension but normal platelets, normal liver enzymes, no symptoms, and no fetal compromise, where expectant management with close surveillance is indicated.

Preeclampsia is filed in memory as a single 'deliver the baby' diagnosis; the candidate skips the two-step reasoning (severe features present or absent, then gestational age) that the question is actually testing.

What to do instead

Adopt a fixed two-axis approach for every hypertensive stem: first classify severity using the strict feature list (BP thresholds, platelets, transaminases, creatinine, pulmonary oedema, symptoms, fetal growth), then apply the gestational-age rule at 37 weeks. Practise by classifying ten short vignettes before looking at the options.

Mistake 3

For a woman with locally advanced cervical cancer (for example stage IIB with parametrial extension, or a bulky IB3 tumour), the candidate selects radical hysterectomy with pelvic lymphadenectomy instead of primary concurrent chemoradiation.

A general 'cancer equals surgery' heuristic overrides the FIGO stage-to-modality map, and the candidate has not rehearsed which stages cross the surgical/radiotherapy boundary or what the 2018 staging revisions changed.

What to do instead

Build and memorise a one-page FIGO stage-to-primary-treatment table for cervix, endometrium, ovary, and vulva, including the stage cut-offs where surgery stops and chemoradiation begins, and redraw it from memory weekly until it is reproduced without error.

Mistake 4

In an anovulatory woman with polycystic ovary syndrome and no other infertility factors, the candidate chooses clomiphene citrate as first-line ovulation induction and reserves letrozole for clomiphene failure.

Older training material and habit fix clomiphene as the default, and the candidate has not updated to current evidence and guideline recommendations that place letrozole first for PCOS.

What to do instead

Maintain a short, dated 'first-line therapy' list per diagnosis (PCOS ovulation induction, unexplained infertility, male factor, tubal disease) with the supporting trial or guideline beside each entry, and review it whenever a guideline revision is published.

Mistake 5

For a woman with urodynamically confirmed pure stress urinary incontinence and no previous treatment, the candidate recommends a midurethral sling as the first intervention rather than supervised pelvic floor muscle training.

The candidate jumps to the operation because the diagnosis is clear and surgery feels definitive, forgetting that the question tests the treatment hierarchy and the counselling that must precede surgery.

What to do instead

For every urogynecology stem, state the diagnosis, then recite conservative measures before any surgical option, and check whether the stem mentions failed conservative therapy. If it does not, the surgical options are distractors.

Mistake 6

A 58-year-old woman presents with a single episode of postmenopausal bleeding and a normal-looking transvaginal ultrasound; the candidate selects hysteroscopy with polypectomy, hormonal therapy, or repeat scanning as the first step rather than endometrial sampling.

The reassuring scan anchors the candidate away from cancer, and the rule that postmenopausal bleeding mandates tissue diagnosis regardless of endometrial thickness is not held with sufficient confidence.

What to do instead

Anchor the rule 'postmenopausal bleeding equals tissue' and treat imaging as a triage tool, not an exclusion test. Rehearse stems in which the ultrasound is normal, because that is exactly where the rule is tested.

Mistake 7

The candidate prescribes a combined oestrogen-progestogen contraceptive to a woman with migraine with aura, or within 21 days postpartum with additional risk factors, treating only age and smoking status as contraindications.

Contraindication screening is recalled as a short informal list rather than as structured UKMEC categories, so conditions designated category 3 or 4 are missed when they appear in the past medical history rather than in the main complaint.

What to do instead

Memorise the UKMEC category 3 and 4 conditions for combined hormonal contraception as a fixed set and apply a four-question screen to every contraception stem: migraine type, blood pressure and vascular risk, postpartum interval and breastfeeding, and smoking plus age.

Mistake 8

The candidate describes cell-free DNA screening as diagnostic and counsels a patient that a low-risk result excludes aneuploidy, or conversely offers termination on the basis of a high-risk combined first-trimester result without confirmatory invasive testing.

Screening and diagnostic tests are stored as a single concept, and the performance characteristics (detection rate, positive predictive value, placental origin of cell-free DNA, confined placental mosaicism) are not linked to the counselling implications.

What to do instead

For each prenatal test, write three lines: what it detects, its detection and false-positive profile, and what confirmation is required. Drill the sentence 'screening changes probability, diagnosis changes management' until the counselling step follows automatically.

Mistake 9

In a case of maternal sepsis with hypotension and tachycardia, the candidate orders blood cultures, lactate, and imaging, then awaits results before giving broad-spectrum antibiotics, or gives several litres of crystalloid without vasopressor escalation.

The candidate applies a ward round sequence (investigate, then treat) to a resuscitation scenario, and the time-critical targets for antibiotics and mean arterial pressure have not been rehearsed as absolute rules.

What to do instead

Rehearse obstetric sepsis as a timed bundle: cultures drawn but never delaying antibiotics within one hour, source control, fluids with early vasopressors for refractory hypotension, and escalation to senior and critical care. Answer bundle stems by time stamp, not by sequence of tests.

Mistake 10

Faced with a competent pregnant woman who refuses a recommended intervention, the candidate selects 'proceed in the fetus's best interests' or 'obtain consent from the husband or family', rather than respecting the refusal after documenting capacity and counselling.

The candidate conflates fetal beneficence with decision-making authority and has not learned a structured capacity assessment, so the ethical principle being tested is replaced by an emotional response to the scenario.

What to do instead

Apply a fixed four-step framework to every ethics stem: assess capacity, disclose risks and alternatives, confirm the decision is voluntary and informed, then respect it and document. Treat third-party consent options and fetal-best-interest override options as wrong whenever the woman has capacity.
