Anatomy, Physiology, Microbiology for NORCET | NPrep

Anatomy, Physiology and Microbiology get few direct NORCET questions: candidates recalled about 1 Anatomy question of 100 in NORCET 10 Prelims, with no separate Physiology or Microbiology count. But they sit behind Medical-Surgical and infection control scenarios. Revise them briefly, alongside the clinical subjects, rather than as a long separate block.

Updated 7 November 2026. The exam pattern is from AIIMS Notice 103/2026. Question counts are NPrep's analysis of the NORCET 10 Prelims paper as recalled by candidates; AIIMS publishes no subject weightage. Science facts follow standard nursing textbooks.

How many Anatomy and Physiology questions come in NORCET?

Very few as direct questions. AIIMS does not publish weightage, and one recalled paper is not a rule, so treat the count as a guide. In NORCET 10 Prelims, candidates recalled about 1 question labelled Anatomy, against about 23 for Medical-Surgical Nursing. The full split is in our NORCET 10 Prelims analysis.

The real value is hidden. A question on potassium in renal failure tests renal physiology. A question on airborne precautions tests microbiology. Stage II has 160 nursing questions focused on case scenarios, so you need the science, applied.

Which Anatomy topics matter most for NORCET?

Learn the anatomy that nurses use at the bedside:

System	Know this
Skeleton	206 bones in an adult, 33 vertebrae, major joints
Nervous	12 pairs of cranial nerves, 31 pairs of spinal nerves, brain lobes and their functions
Heart	Chambers, valves, coronary arteries, conduction from the SA node to the Purkinje fibres
Respiratory	Right lung 3 lobes, left lung 2; the right main bronchus is shorter, wider and more vertical
Renal	Retroperitoneal kidneys, nephron as the functional unit
Injection sites	Deltoid, vastus lateralis, ventrogluteal; dorsogluteal risks the sciatic nerve
Reproductive	Pelvis types and diameters, uterus, fetal skull, which link directly to OBG nursing

Cranial nerve testing is a favourite because it is practical:

Test	Nerve
Smell	I, Olfactory
Pupil reaction and most eye movement	III, Oculomotor
Facial expression	VII, Facial
Gag reflex	IX and X, Glossopharyngeal and Vagus
Shrugging the shoulders	XI, Accessory
Sticking out the tongue	XII, Hypoglossal

Which Physiology values should I memorise?

These normal values come back in almost every clinical subject. Reference ranges vary slightly between textbooks and labs.

Value	Normal adult range
Blood pH	7.35 to 7.45
PaCO2	35 to 45 mmHg
Bicarbonate	22 to 26 mEq/L
Sodium	135 to 145 mEq/L
Potassium	3.5 to 5.0 mEq/L
Calcium	8.5 to 10.5 mg/dL
Platelets	1.5 to 4.5 lakh per microlitre
WBC	4,000 to 11,000 per microlitre
RBC lifespan	About 120 days
GFR	About 125 mL a minute
Minimum urine output	About 0.5 mL/kg an hour
SA node rate	60 to 100 a minute
AV node rate	40 to 60 a minute

Two formulas and four hormones are enough for most questions:

• Cardiac output = heart rate × stroke volume, about 5 litres a minute at rest.
• Mean arterial pressure = (systolic + 2 × diastolic) ÷ 3. For 120/80 mmHg, that is about 93 mmHg.
• ADH holds water. Aldosterone holds sodium and loses potassium.
• Parathyroid hormone raises blood calcium. Calcitonin lowers it.

Which Microbiology topics matter most for NORCET?

Focus on what changes nursing action: how an organism spreads and how you kill it.

Area	Know this
Airborne spread	Tuberculosis, measles, chickenpox
Droplet spread	Influenza, pertussis, diphtheria, mumps
Contact spread	MRSA, Clostridioides difficile
Faecal-oral spread	Cholera, typhoid, hepatitis A and E
Blood-borne spread	HIV, hepatitis B and C
Gram stain	Gram-positive stains purple, Gram-negative stains pink
Acid-fast stain	Ziehl-Neelsen, for Mycobacterium tuberculosis

Sterilisation questions are direct and scoring:

Method	Standard setting or use
Autoclave	121°C, 15 psi, 15 minutes
Hot air oven	160°C for 2 hours
Ethylene oxide	Heat-sensitive equipment
2% glutaraldehyde	High-level disinfection of instruments such as endoscopes

Immunology is the third block:

Antibody	Key fact
IgG	Most abundant; crosses the placenta
IgM	First antibody in a new infection
IgA	In secretions and colostrum
IgE	Allergy and parasites

Hypersensitivity	Example
Type I, immediate	Anaphylaxis
Type II, cytotoxic	Mismatched blood transfusion
Type III, immune complex	Systemic lupus erythematosus
Type IV, delayed	Mantoux test

Hand hygiene, PPE order and biomedical waste are in Fundamentals of Nursing for NORCET. Vectors and vaccines are in Community Health Nursing for NORCET.

What does a NORCET-style question look like?

These are NPrep practice questions in the NORCET style, not questions from a past paper.

A toddler is brought in coughing after inhaling a peanut. In which airway is the object most likely to lodge?

A. Left main bronchus B. Right main bronchus C. Oesophagus D. Left upper lobe bronchus

Answer: B. The right main bronchus is shorter, wider and more vertical, so aspirated objects usually enter it.

A newborn has protective antibodies from the mother at birth. Which antibody crossed the placenta?

A. IgA B. IgE C. IgG D. IgM

Answer: C. IgG is the antibody that crosses the placenta. IgA reaches the baby later, through colostrum.

How should I study these subjects for NORCET?

Do not spend weeks on them. NPrep recommends one quick pass, then linking each system to its clinical subject:

When you study	Revise
Cardiac conditions in Medical-Surgical Nursing	Heart anatomy, conduction, cardiac output
Renal and fluid disorders	Nephron, electrolytes, acid-base
Infection control in Fundamentals	Spread, sterilisation
Labour and delivery in OBG	Pelvis, fetal skull
Drug action in Pharmacology	Receptors and normal values

Do this in the "remaining subjects" phase of the NORCET 12 study plan, from 29 December 2026 to 31 January 2027. Put the normal values on one page and revise it weekly.

FAQs

How many Anatomy questions come in NORCET?

Very few directly. Candidates recalled about 1 question labelled Anatomy of 100 in NORCET 10 Prelims. AIIMS publishes no weightage, and the count changes by paper.

Is Anatomy and Physiology important for NORCET?

Yes, more than its direct count suggests. Normal values, conduction, the nephron and acid-base balance sit behind many Medical-Surgical case scenarios, especially in Stage II.

Is Microbiology asked in NORCET?

Mostly through infection control: how diseases spread, isolation precautions, sterilisation and disinfection. Learn it through nursing action rather than the structure of each organism.

What is the autoclave temperature for sterilisation?

The standard setting is 121°C at 15 psi for 15 minutes.

Which immunoglobulin crosses the placenta?

IgG. It gives the newborn passive immunity from the mother. IgA is passed later through colostrum.

How long should I study Anatomy and Physiology for NORCET?

NPrep recommends about one week in your first pass, then revising each system with its clinical subject. Most of your time should go to Medical-Surgical Nursing and OBG.
