Official GMC references, the anatomy of 2026-format clinical vignettes, and interactive sample questions demonstrating the shift from factual recall to applied clinical reasoning.

Anatomy of a 2026 PLAB MLA Clinical Vignette

The cornerstone of the new examination format — understanding how each component is structured and what it tests

1

👤 Patient Demographics

Sets the baseline risk profile — age, gender, ethnicity, occupation. Primes differential diagnosis from the outset.

2

🚨 Presenting Complaint

The clinical 'hook' — chief symptom, onset, duration, severity. Directs initial clinical reasoning.

3

📋 Clinical History

PMH, drug history, social history, family history. Layered complexity requiring synthesis of multiple data points.

4

🌡️ Physical Findings

Vital signs (ABCDE approach), targeted examination results. Tests pattern recognition and red flag identification.

5

🧪 Investigations

Bedside tests (ECG, urinalysis), bloods, imaging. Interpretation in clinical context, not isolation.

6

The Lead-in Question

The clinical task — next investigation, next management step, most likely complication. Tests prioritisation and patient safety.

Note for candidates: From September 2026, PLAB AKT questions follow the longer clinical vignette format. If your study materials were published before 2024, they likely lack updated conditions and question style. Always cross-reference with the official GMC Content Map.

Traditional Format — Orientation Examples

Five questions derived from the official GMC example set — stems paraphrased for clarity

Q1: Chronic diarrhoea + weight loss + intensely itchy rash — small bowel biopsy finding?

A middle-aged man has long-standing diarrhoea and weight loss, plus an intensely pruritic erythematous rash on buttocks/thighs. Blood tests show anaemia with anisocytosis. What is the most likely histological feature on small bowel biopsy?

A Hyperplasia of Brunner's glands
B Increased intraepithelial macrophages
C Increased lymphocytes in submucosa
D Ulceration
E Villous atrophy
Reveal Answer
E Villous atrophy ✓ CORRECT
GI / Malabsorption Applied Histology

Q2: ED request for strong analgesia + malnourished/restless — key substance?

A young adult presents with abdominal pain requesting strong analgesia. She appears malnourished and restless/irritable. Which non-prescribed substance is most important to enquire about?

A Alcohol
B Amphetamines
C Cannabis
D Cocaine
E Heroin
Reveal Answer
E Heroin ✓ CORRECT
Substance Misuse ED Presentations

Q3: Painless jaundice + pale stools + weight loss — investigation?

An older patient has painless jaundice, pale stools and weight loss. Examination unremarkable. Which investigation is most appropriate?

A CT scan of abdomen
B ERCP
C MR cholangio-pancreatography
D PET scan
E Ultrasound of abdomen
Reveal Answer
A CT scan of abdomen ✓ CORRECT
Hepatobiliary Investigation Choice

Q4: Paracetamol overdose, level below NAC line — action?

A patient presents after an impulsive paracetamol overdose and now expresses regret. Level below treatment line. What is the most appropriate course of action?

A Admit to psychiatric ward
B Assessment by liaison psychiatry in ED
C Discharge home with GP follow-up
D Prescribe antidepressant
E Refer for CBT
Reveal Answer
B Assessment by liaison psychiatry in ED ✓ CORRECT
Self-harm / Overdose Safety / Governance

Q5: Post-op hip fracture + pleuritic pain + haemoptysis — test?

Elderly inpatient post-hip surgery develops acute chest pain, breathlessness, haemoptysis. Mild hypoxia. Which diagnostic investigation is most appropriate?

A Arterial blood gases
B Chest X-ray
C CT pulmonary angiogram
D D-dimer
E ECG
Reveal Answer
C CT pulmonary angiogram ✓ CORRECT
Respiratory / PE Acute Care

2026 Clinical Vignette Format — Sample Questions

Obstetrics & Gynaecology · Primary Care 2026 Format

Women's Health: HRT & Breakthrough Bleeding

Clinical Vignette

A 54-year-old woman presents to her GP with a 3-week history of unscheduled breakthrough vaginal bleeding. She has been on continuous combined HRT for six months. She admits non-compliance with the progestogen component for two months (unopposed oestrogen only). BMI 41, well-controlled hypertension, never had a smear test. No cervical or vaginal pathology. Pelvic ultrasound: endometrial thickness 9mm.

What is the most appropriate next investigation?

A Repeat pelvic ultrasound in 3 months
B High-vaginal and endocervical swabs
C Pipelle endometrial biopsy
D Reassurance and adjustment of HRT dose
E Hysterectomy referral
Reveal Answer & Clinical Reasoning
C Pipelle endometrial biopsy ✓ CORRECT
Clinical Reasoning: Unopposed oestrogen exposure + elevated BMI (independent risk factor for endometrial hyperplasia/carcinoma) + thickened endometrium (9mm) + unscheduled bleeding mandates tissue diagnosis. Reassurance alone would be clinically unsafe. This vignette tests the candidate's ability to synthesise multiple risk factors and prioritise the safety-critical next step.

Respiratory · General Practice 2026 Format

Primary Care: COPD Step-Up Management

Clinical Vignette

72-year-old man, 10-year COPD history. Worsening breathlessness, mMRC 3, one recent exacerbation. On LAMA monotherapy. Eosinophils 350 cells/µL. CXR normal, BMI 24. Using salbutamol four times daily. Inhaler technique excellent.

What is the most appropriate next pharmacological step?

A Add extra SABA only
B Start Prednisolone and Amoxicillin
C Switch to triple therapy (ICS/LABA/LAMA)
D Refer for LTOT assessment
E Add Roflumilast
Reveal Answer & Clinical Reasoning
C Triple therapy (ICS/LABA/LAMA) ✓ CORRECT
Clinical Reasoning: GOLD 2026: persistent symptoms + exacerbations + eosinophils ≥300 → triple therapy gives greatest mortality and symptom benefit. Raised eosinophils = treatable trait indicating ICS responsiveness.
