NEET PG Clinical Scenario Questions 2026: Important Case-Based MCQs with Answers

Clinical Scenario Questions for NEET PG 2026

A plain concept-based question checks whether you remember something. A scenario-based question checks if you can use it. NEET PG increasingly includes the second type of questions, since it reflects real clinical decision-making far better than a one-line recall question ever could.

Practising this format also builds speed. The first time you see a scenario, you are figuring out both the medicine and the format. By the twentieth time, the format is second nature, and all your effort goes into the actual clinical reasoning.

NEET PG 2026 Clinical Scenario Questions with Answers

Medicine and Endocrine Emergencies

Q1. A 60-year-old man develops crushing chest pain and sweating. ECG shows ST elevation in leads V1 to V4. Which artery is most likely blocked?

A) Right coronary artery

B) Left anterior descending artery

C) Left circumflex artery

D) Left main coronary artery

Answer: B) Left anterior descending artery. Changes in leads V1 to V4 point to the anterior wall of the heart, which is supplied by the LAD.

Q2. A patient on long-term steroids stops them suddenly and develops low blood pressure, vomiting, and confusion. What is the most likely diagnosis?

A) Addisonian crisis

B) Thyroid storm

C) Diabetic ketoacidosis

D) Cushing syndrome

Answer: A) Addisonian crisis. Sudden steroid withdrawal can trigger acute adrenal insufficiency, since the adrenal glands haven't had time to resume normal cortisol production.

Q3. A patient with known hyperthyroidism develops high fever, a fast heart rate, and confusion after surgery. What is the most likely diagnosis?

A) Thyroid storm

B) Myxedema coma

C) Addisonian crisis

D) Malignant hyperthermia

Answer: A) Thyroid storm. Surgery or infection can trigger this life-threatening spike in thyroid hormone activity in a patient with pre-existing hyperthyroidism.

Q4. An elderly diabetic presents confused, with very high blood glucose, but no significant ketones and a normal blood pH. What is the most likely diagnosis?

A) Diabetic ketoacidosis

B) Hyperosmolar hyperglycaemic state

C) Hypoglycaemic coma

D) Lactic acidosis

Answer: B) Hyperosmolar hyperglycaemic state. This condition is more common in older type 2 diabetics and features very high glucose with little to no ketosis, unlike DKA.

Surgical Emergencies

Q5. A patient with acute pancreatitis develops bluish discolouration around the belly button. What does this finding suggest?

A) Cullen's sign, indicating bleeding around the pancreas

B) Normal finding in pancreatitis

C) Liver failure

D) Bowel perforation

Answer: A) Cullen's sign. This bluish discolouration around the umbilicus suggests bleeding tracking from the pancreas into the tissue beneath the skin.

Q6. A patient with sudden, severe abdominal pain has a rigid, board-like abdomen. X-ray shows free air under the diaphragm. What is the most likely cause?

A) Acute appendicitis

B) Perforated hollow viscus

C) Acute pancreatitis

D) Bowel obstruction

Answer: B) Perforated hollow viscus. Free air under the diaphragm on an erect X-ray is a classic sign that a hollow organ, often the stomach or duodenum, has perforated.

Obstetrics, Gynaecology, and Paediatrics

Q7. A pregnant woman at 34 weeks develops sudden severe abdominal pain, vaginal bleeding, and a tender, hard uterus. What is the most likely diagnosis?

A) Placenta praevia

B) Placental abruption

C) Normal labour

D) Uterine rupture

Answer: B) Placental abruption. A painful, tender, hard uterus with bleeding points to the placenta separating early from the uterine wall, unlike placenta praevia, which usually causes painless bleeding.

Q8. Ultrasound in a pregnant woman shows the placenta growing abnormally into the uterine muscle wall. What is this condition called?

A) Placenta praevia

B) Placenta accreta

C) Vasa praevia

D) Placental abruption

Answer: B) Placenta accreta. In this condition, the placenta attaches too deeply into the uterine wall, raising the risk of severe bleeding at delivery.

Q9. A 2-year-old develops a seizure during a high fever, with no other neurological problem found. What is the most likely diagnosis?

A) Epilepsy

B) Febrile seizure

C) Meningitis

D) Breath-holding spell

Answer: B) Febrile seizure. These seizures happen in young children during a rapid rise in body temperature and usually don't indicate an underlying seizure disorder.

Q10. A 6-month-old has episodes of severe abdominal pain, drawing the knees to the chest, with red, jelly-like stools. What is the most likely diagnosis?

A) Intussusception

B) Pyloric stenosis

C) Volvulus

D) Meckel's diverticulum

Answer: A) Intussusception. One part of the bowel telescopes into another, and red, jelly-like stool is a classic finding in this condition.

Neurology and Psychiatry

Q11. A patient on multiple serotonin-boosting drugs develops fever, tremors, and confusion. What is the most likely diagnosis?

A) Neuroleptic malignant syndrome

B) Serotonin syndrome

C) Malignant hyperthermia

D) Anticholinergic toxicity

Answer: B) Serotonin syndrome. This is caused by too much serotonin activity, often from combining drugs like antidepressants, and needs prompt recognition and treatment.

Q12. A patient develops ascending weakness in both legs a few weeks after a diarrhoeal illness. What is the most likely diagnosis?

A) Guillain-Barre syndrome

B) Myasthenia gravis

C) Multiple sclerosis

D) Stroke

Answer: A) Guillain-Barre syndrome. This condition often follows an infection and causes weakness that spreads upward from the legs, sometimes reaching the breathing muscles.

Q13. A patient starts a new anticonvulsant and develops widespread skin blistering and peeling within two weeks. What is the most likely diagnosis?

A) Stevens-Johnson syndrome

B) Contact dermatitis

C) Erythema multiforme minor

D) Urticaria

Answer: A) Stevens-Johnson syndrome. This is a severe drug reaction affecting the skin and mucous membranes, and it requires stopping the drug immediately and urgent care.

ENT, Ophthalmology, and Emergency Medicine

Q14. A patient with sore throat develops a muffled voice, drooling, and difficulty opening the mouth. What is the most likely diagnosis?

A) Peritonsillar abscess

B) Acute tonsillitis

C) Epiglottitis

D) Pharyngitis

Answer: A) Peritonsillar abscess. Also called quinsy, this collection of pus near the tonsil causes a muffled "hot potato" voice and difficulty opening the mouth fully.

Q15. A patient suddenly loses vision in one eye without pain. Examination shows a pale retina with a bright red spot at the centre. What is the most likely diagnosis?

A) Central retinal artery occlusion

B) Central retinal vein occlusion

C) Retinal detachment

D) Acute angle-closure glaucoma

Answer: A) Central retinal artery occlusion. The blocked artery causes sudden, painless vision loss, and the "cherry red spot" is a classic finding on examination.

Q16. A patient after chest trauma has severe breathlessness, low blood pressure, and no breath sounds on one side, with a shift of the trachea. What is the most likely diagnosis?

A) Simple pneumothorax

B) Tension pneumothorax

C) Haemothorax

D) Flail chest

Answer: B) Tension pneumothorax. Air trapped under pressure in the chest pushes the trachea to the opposite side and needs immediate needle decompression, not investigation first.

Q17. A patient with a long bone fracture develops breathlessness, confusion, and a rash over the chest a day later. What is the most likely diagnosis?

A) Pulmonary embolism

B) Fat embolism syndrome

C) Pneumonia

D) Acute respiratory distress syndrome

Answer: B) Fat embolism syndrome. This classic triad of breathlessness, confusion, and petechial rash typically appears 24 to 72 hours after a long bone fracture.

Infectious Disease and Toxicology

Q18. A patient with dengue fever develops cold extremities, a weak pulse, and a narrowing gap between systolic and diastolic blood pressure. What is the most likely diagnosis?

A) Dengue shock syndrome

B) Simple dengue fever

C) Typhoid fever

D) Septic shock from another cause

Answer: A) Dengue shock syndrome. A narrowing pulse pressure along with cold extremities and a weak pulse signals the shock stage of severe dengue, which needs urgent fluid management.

Q19. A patient who took a large dose of aspirin presents with ringing in the ears, rapid breathing, and confusion. What is the most likely diagnosis?

A) Salicylate poisoning

B) Paracetamol overdose

C) Opioid overdose

D) Benzodiazepine overdose

Answer: A) Salicylate poisoning. Tinnitus (ringing in the ears) combined with rapid breathing is a classic early sign of aspirin toxicity.

Q20. A patient develops severe muscle pain, dark urine, and confirmed muscle breakdown after being trapped under debris for hours. What is the most likely diagnosis?

A) Rhabdomyolysis

B) Acute kidney injury from dehydration

C) Compartment syndrome only

D) Fat embolism syndrome

Answer: A) Rhabdomyolysis. Crushed muscle releases its contents into the bloodstream, and this can seriously damage the kidneys if not treated promptly with fluids.

How to Use These NEET PG Clinical Scenario Questions

Read the whole case first. Don't jump to the options immediately. Try to form your own answer in your head before you even look at the given solutions.

Notice how each scenario gives you two or three clues, not just one. Real exam questions rarely hand you the diagnosis in a single word. They expect you to put small details together like the timing, the trigger, and the exact finding to reach the right answer.

Once you have practised these questions, attempt full previous year papers to see how scenario questions integrate into the rest of a real NEET PG paper. Full-length, timed practice also helps you get used to the current 42-minute, sectioned exam format.
