Public Health
Epidemiological triad: agent, host, environment; disease causation models include germ theory, epidemiological triad and web of causation.
Incidence = new cases / population at risk per unit time; prevalence = all cases / total population at a point or period; Prevalence ≈ Incidence × Duration.
Attack rate = new cases during outbreak / population exposed × 100; case fatality rate = deaths from disease / diagnosed cases × 100.
Sensitivity = TP/(TP+FN); Specificity = TN/(TN+FP); Positive predictive value = TP/(TP+FP); PPV rises as prevalence rises.
Levels of prevention: primordial (risk-factor control), primary (immunisation, health promotion), secondary (early detection/screening), tertiary (rehabilitation), quaternary (avoid over-medicalisation).
Herd immunity threshold = 1 − 1/R₀; for measles R₀ ≈ 12–18, requiring ~92–95% two-dose coverage.
Notifiable diseases in India include cholera, plague, dengue, malaria, polio, rabies, measles; Integrated Disease Surveillance Programme (IDSP) reports weekly S/P/L forms.
Screening tests must be acceptable, safe, cheap and have high sensitivity; confirmatory tests require high specificity.
Community Health and Nursing Science
Primary Health Centre norm: one PHC per 30,000 rural population (20,000 in hilly/tribal areas); one Community Health Centre per 1,20,000 (80,000 in difficult areas) with 30 beds.
Sub-centre norm: one per 5,000 population (3,000 in hilly/tribal); staffed by one ANM and one Male Health Worker; ASHA one per 1,000 population (village-based).
Nursing process: Assessment → Diagnosis → Planning → Implementation → Evaluation (ADPIE); documentation uses SOAP notes (Subjective, Objective, Assessment, Plan).
Vital signs adult ranges: pulse 60–100/min, respiratory rate 12–20/min, BP 120/80 mmHg (normal), oral temperature 36.5–37.5°C, SpO₂ ≥ 95%.
Universal precautions: hand hygiene (WHO 5 moments), gloves for body-fluid contact, sharps disposal in puncture-proof container, spill management with 1% sodium hypochlorite.
Cold chain: OPV at −20°C, measles and BCG at −20°C to −8°C, DPT/TT/Hep B at 2–8°C; VVM (vaccine vial monitor) changes from inner square to outer square when exposed to heat.
Home visit bag technique keeps equipment clean; bag should be kept on a clean surface, not on the patient's bed; wash hands before and after each procedure.
Growth monitoring: weight-for-age (underweight), height-for-age (stunting), weight-for-height (wasting); MUAC <11.5 cm indicates severe acute malnutrition in children 6–59 months.

General Science
SI units: force – newton (N), pressure – pascal (Pa), work/energy – joule (J), power – watt (W), frequency – hertz (Hz), electric charge – coulomb (C).
Newton's laws: F = ma; action–reaction equal and opposite; inertia keeps a body at rest or uniform motion unless acted on by a net force.
Ohm's law: V = IR; power P = VI = I²R = V²/R; resistors in series add (R = R₁+R₂), in parallel 1/R = 1/R₁ + 1/R₂.
Acids turn blue litmus red, bases turn red litmus blue; pH scale 0–14; neutral pH = 7; strong acid HCl, strong base NaOH.
Photosynthesis: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ in the presence of chlorophyll and sunlight; occurs in chloroplasts.
Human digestive enzymes: salivary amylase (starch), pepsin (protein in stomach, acidic pH), trypsin (protein in small intestine), lipase (fat).
Cell organelles: mitochondria (ATP production), ribosomes (protein synthesis), nucleus (genetic material), lysosome (digestion), chloroplast (photosynthesis in plants).
Common scientific instruments: barometer (pressure), hygrometer (humidity), anemometer (wind speed), seismograph (earthquakes), sphygmomanometer (BP).
Mathematics and Reasoning
Percentage: x% of N = (x/100)×N; percentage increase = (new − old)/old × 100; successive change a% then b% gives net = a + b + ab/100.
Simple interest SI = P×R×T/100; compound interest A = P(1 + R/100)^T; CI = A − P.
Speed = distance/time; average speed for equal distances = 2xy/(x+y); train crossing pole takes length/speed time.
Ratio and proportion: if a:b = c:d then ad = bc; partnership profit shares are proportional to capital × time.
Permutation nPr = n!/(n−r)!; combination nCr = n!/(r!(n−r)!); probability of event = favourable/total outcomes.
Number series and coding-decoding: identify pattern (difference, ratio, square/cube, alternate series); letter positions A=1…Z=26; reverse position = 27 − forward position.
Blood relations and direction sense: draw a family tree or compass diagram; left/right turns change the facing direction by 90°.
Syllogism: use Venn diagrams; 'All A are B' does not imply 'All B are A'; 'Some A are B' implies 'Some B are A'.

उपसर्ग और प्रत्यय: उपसर्ग शब्द के आरम्भ में जुड़ता है (प्र + हार = प्रहार); प्रत्यय अंत में (लड़क + पन = लड़कपन)।
वाक्य के अंग: उद्देश्य और विधेय; वाक्य भेद – सरल, संयुक्त, मिश्र; रचना के आधार पर वर्गीकरण।
अलंकार: अनुप्रास (वर्ण की आवृत्ति), उपमा (समानता), रूपक (अभेद), उत्प्रेक्षा (संभावना), यमक (शब्द की आवृत्ति भिन्न अर्थ)।
रस के नौ भेद: शृंगार, हास्य, करुण, रौद्र, वीर, भयानक, बीभत्स, अद्भुत, शांत; शृंगार को रसराज कहते हैं।
मुहावरे और लोकोक्तियाँ: 'नौ दो ग्यारह होना' = भाग जाना; 'अंधे की लाठी' = एकमात्र सहारा।
वर्तनी और शब्द-शुद्धि: 'क्ष' संयुक्त व्यंजन है; 'ज्ञ' = ज् + ञ; अनुस्वार (ं) और अनुनासिक (ँ) का प्रयोग।
English
Tenses: present perfect (has/have + V3) for past action with present relevance; past perfect (had + V3) for the earlier of two past actions.
Active to passive: object becomes subject, verb becomes be + V3, agent introduced by 'by'; only transitive verbs can be passivised.
Articles: 'a/an' for indefinite countable singulars (an before vowel sound), 'the' for definite/specific nouns and unique entities (the sun).
Prepositions: in (enclosed space/large area), on (surface), at (point); since + point of time, for + duration.
Direct to indirect speech: change tense one step back, pronouns according to reporting verb, time/place words (now → then, here → there).
Common idioms: 'once in a blue moon' (very rarely), 'a blessing in disguise' (apparent misfortune that turns good), 'to bite the bullet' (face a difficult situation).
Subject–verb agreement: singular subject takes singular verb; 'each/every/either/neither' take singular verbs; collective nouns usually singular.
