NORCET Mains Medical-Surgical Nursing PYQs with Clinical Rationale

What is the NORCET Mains Medical-Surgical Nursing Questions Test?

A Prelims-level question asks what a term means. A Mains-level question gives a nurse a real situation and asks for the next action, the first action, or the most likely cause. This shift is deliberate. AIIMS uses Mains to separate candidates who know the syllabus from candidates who can apply it under pressure, which is exactly what the 10 common mistakes candidates make in NORCET Mains covers in more depth: many aspirants prepare at Prelims depth and meet a very different kind of question on exam day.

NORCET Mains Airway and Emergency PYQs with Clinical Rationale

Q1. A nurse performing bag-valve-mask ventilation notices inadequate chest rise. What is the FIRST action?

A. Increase oxygen flow B. Reposition the head and mask seal C. Change the mask size D. Begin chest compressions

Answer: B. Reposition the head and mask seal
Inadequate chest rise during BVM ventilation almost always means a poor seal or an obstructed airway, not a flow problem. Fixing the seal and head position is the fastest, lowest-risk correction, and it comes before assuming equipment failure or escalating to compressions.

Q2. A trauma patient with suspected spinal injury requires airway opening. Which manoeuvre is used?

A. Head tilt-chin lift B. Jaw thrust C. Chin lift only D. Triple airway manoeuvre

Answer: B. Jaw thrust
Head tilt-chin lift moves the cervical spine, which is unsafe when spinal injury is suspected. Jaw thrust opens the airway by displacing the mandible forward alone, keeping the neck neutral throughout.

Q3. A chest tube drainage system shows continuous bubbling in the water seal chamber. What does this mean?

A. Normal finding B. Air leak C. Blockage D. High suction

Answer: B. Air leak
Intermittent bubbling that matches respiration is normal. Continuous bubbling means air is entering the system somewhere it shouldn't, either from the patient's pleural space or a loose connection, and needs to be traced and fixed.

Q4. In tension pneumothorax, what is the immediate management?

A. Chest tube B. Needle thoracostomy C. BiPAP D. CPAP

Answer: B. Needle thoracostomy
A chest tube is the definitive treatment, but tension pneumothorax is a rapidly fatal emergency. Needle decompression buys time immediately, before a chest tube can be set up and inserted.

Q5. Sudden tracheal deviation to the left indicates:

A. Left pleural effusion B. Right tension pneumothorax C. Gastric distension D. Cardiac tamponade

Answer: B. Right tension pneumothorax
Trapped air under pressure on one side pushes the mediastinum, and the trachea with it, toward the opposite side. Deviation to the left points to a problem building pressure on the right.

NORCET Mains Cardiac PYQs with Clinical Rationale

Q6. Which electrolyte imbalance increases the risk of digoxin toxicity?

A. Hyperkalemia B. Hypokalemia C. Hypercalcemia D. Hyponatremia

Answer: B. Hypokalemia
Digoxin and potassium compete for the same binding site on the Na-K-ATPase pump. When potassium drops, digoxin binds more readily, raising toxicity risk even without any change in dose. This exact question appeared in more than one previous year paper we reviewed, in slightly different subjects, which tells you how consistently it's tested.

Q7. Peak T waves on an ECG indicate:

A. Hypokalemia B. Hyperkalemia C. Hypercalcemia D. Hypomagnesemia

Answer: B. Hyperkalemia
Elevated potassium changes cardiac cell membrane excitability, and tall, peaked T waves are usually the earliest ECG sign. As potassium climbs further, the PR interval widens and the QRS complex broadens, eventually toward a dangerous sine-wave pattern.

Q8. A patient underwent CABG. Two days later, drainage output suddenly drops from 80 mL/hr to 10 mL/hr, with new hypotension, dizziness, and raised JVP. What is the most probable cause?

A. Cardiac tamponade with a blocked drain B. Internal bleeding C. Pulmonary edema D. Hypovolemic shock

Answer: A. Cardiac tamponade with a blocked drain
This exact clinical picture, sudden drainage drop plus hypotension plus raised JVP, appeared in two separate NORCET Mains papers we checked. A blocked chest drain lets blood accumulate around the heart instead of exiting the tube, and the combination of low output with rising JVP is the giveaway, since internal bleeding would typically increase drainage, not stop it.

Q9. Normal central venous pressure (CVP) range is:

A. 0–2 mmHg B. 2–6 mmHg C. 10–15 mmHg D. 20–25 mmHg

Answer: B. 2–6 mmHg
CVP reflects right atrial pressure and, indirectly, fluid status. This normal range is a fixed number worth memorising outright, since questions often ask you to judge whether a given reading points to volume overload or depletion.

NORCET Mains Endocrine and Renal PYQs with Clinical Rationale

Q10. What is the most common cause of Cushing syndrome?

A. Exogenous steroid use B. Adrenal tumour C. Pituitary tumour D. Ectopic ACTH

Answer: A. Exogenous steroid use
This question, or a close variant of it, appeared in two different NORCET Mains cycles we reviewed. Long-term corticosteroid therapy for other conditions, not a tumour, is the leading cause of Cushing syndrome overall. A pituitary tumour causing excess ACTH is technically Cushing disease, a more specific term the exam likes to test separately.

Q11. After a thyroidectomy, a patient reports tingling around the mouth and fingers, and tapping the face causes it to twitch to one side. What is the likely cause?

A. Hematoma compressing the trachea B. Thyroid storm C. Hypocalcemia from accidental parathyroid removal D. Airway obstruction

Answer: C. Hypocalcemia from accidental parathyroid removal
The parathyroid glands sit close to the thyroid and regulate calcium. Accidental damage during thyroid surgery drops calcium, and a positive Chvostek's sign, facial twitching on tapping, is a classic bedside test for this exact complication.

Q12. Which electrolyte imbalance is most common in renal failure?

A. Hyperkalemia B. Hypocalcemia C. Hypernatremia D. Hypokalemia

Answer: A. Hyperkalemia
Failing kidneys lose the ability to excrete potassium, and it accumulates in the blood. This matters clinically because even a mild rise can produce ECG changes, and levels above roughly 7 mEq/L risk fatal arrhythmias, which is why cardiac monitoring is routine in renal failure patients.

NORCET Mains Neurological and Critical Care PYQs with Clinical Rationale

Q13. A patient has a Glasgow Coma Scale score of 4. What intervention is most critical for airway management?

A. High Fowler's position B. Oxygen via nasal cannula C. Prepare for endotracheal intubation D. Deep breathing exercises

Answer: C. Prepare for endotracheal intubation
A GCS this low means the patient cannot reliably protect their own airway from aspiration. Supplemental oxygen or positioning does not fix that underlying risk, which is why definitive airway control takes priority.

Q14. Which sign indicates worsening shock?

A. Warm skin B. Increasing pulse pressure C. Decreasing urine output D. Bounding pulse

Answer: C. Decreasing urine output
Falling urine output reflects reduced kidney perfusion, one of the clearest signs that the body is compensating less well as shock progresses. Warm skin and a bounding pulse point away from shock, not toward it.

Q15. What is considered the gold standard diagnostic test for myocardial infarction?

A. Echocardiography B. Serum troponin levels C. CK-MB D. Chest X-ray

Answer: B. Serum troponin levels
Troponin is highly specific to cardiac muscle injury and stays elevated for days, unlike CK-MB, which rises and falls faster and can also increase with skeletal muscle damage. ECG changes are an essential first clue, but troponin is what confirms the diagnosis.

NORCET Mains Orthopaedic and Miscellaneous PYQs with Clinical Rationale

Q16. According to Wolff's law, a patient presents after a fracture. Which stage involves the bone adapting and strengthening under stress?

A. Ossification B. Callus formation stage C. Remodelling phase D. Hematoma formation

Answer: C. Remodelling phase
Fracture healing moves through hematoma formation, callus formation, and then remodelling, where bone reshapes itself according to the mechanical stress it bears. Wolff's law specifically describes this final adaptive stage, not the earlier steps.

Q17. What is the daily calorie intake requirement for a pregnant female with a moderately active, normal BMI in the second trimester, per NIN 2020 guidelines?

A. 2180 kcal B. 2280 kcal C. 2780 kcal D. 2480 kcal

Answer: D. 2480 kcal
This is a fixed reference figure from national nutrition guidelines, tested as a direct recall fact rather than a reasoning question. It's a low-effort, high-certainty mark once memorised, unlike most of the scenario-based questions above.

How to Use These PYQs in Your Mains Preparation

Notice that almost none of these questions test an individual concept.. The NORCET 11 Mains subject-wise preparation strategy argues for studying disease, drug, and nursing action together rather than as separate topics, and the pattern above is exactly why: a single question can ask about pathology, pharmacology, and priority nursing action all at once. If your exam is close, the NORCET 11 Mains last 7 days strategy and the 30-day Stage 1 study plan both build on this same weightage-first approach.
