50 Hard-Level Community Health Nursing MCQs for NORCET
(Based on Park's Textbook of Preventive and Social Medicine + NORCET exam pattern)
EPIDEMIOLOGY & BIOSTATISTICS (Q 1-10)
Q1. The numerator of "Infant Mortality Rate" includes deaths of infants up to:
- A) 28 days of age
- B) 1 year of age
- C) 5 years of age
- D) 6 months of age
Answer: B - IMR = (Deaths under 1 year / Live births in the same year) × 1000. It is the most sensitive indicator of community health and socioeconomic development.
Q2. A community health nurse is interpreting disease data. "Perinatal mortality rate" includes deaths from:
- A) 22 weeks of gestation to 7 days of life
- B) 28 weeks of gestation to 28 days of life
- C) 28 weeks of gestation to 7 days of life
- D) Birth to 28 days of life
Answer: C - Perinatal mortality rate = (Stillbirths after 28 weeks + Deaths in first 7 days of life) / (Total births including stillbirths) × 1000.
Q3. Which of the following correctly differentiates "Incidence" from "Prevalence"?
- A) Incidence measures existing cases; prevalence measures new cases
- B) Incidence is used only for chronic diseases; prevalence for acute
- C) Prevalence = Incidence × Mean duration of disease
- D) Prevalence is always higher than incidence in acute diseases
Answer: C - The relationship is: Prevalence ≈ Incidence × Mean duration (holds true when disease is in a steady state). For acute diseases, prevalence may be lower than incidence due to short duration.
Q4. In a case-control study on lung cancer, the Odds Ratio (OR) is calculated as 7.5. This means:
- A) Cases are 7.5 times more likely to have the disease than controls
- B) The exposure is 7.5 times more common among cases than controls
- C) 7.5% of cases had the exposure
- D) The relative risk is 7.5
Answer: B - OR in a case-control study compares the odds of exposure in cases vs. controls. It approximates Relative Risk only when disease prevalence is low (rare disease assumption).
Q5. The "Herd Immunity" threshold required to eradicate measles (R₀ = 12-18) is approximately:
- A) 50-60%
- B) 70-75%
- C) 83-94%
- D) 95-99%
Answer: C - Herd immunity threshold = 1 − (1/R₀). For measles with R₀ of 12-18: threshold = 1 − (1/12) to 1 − (1/18) = 83-94%.
Q6. Which study design has the HIGHEST risk of recall bias?
- A) Cohort study
- B) RCT
- C) Case-control study
- D) Cross-sectional study
Answer: C - Case-control studies rely on participants recalling past exposures; cases (who have disease) are more likely to remember past exposures than controls, producing recall (reporting) bias.
Q7. In a screening test, sensitivity is 90% and specificity is 80%. If disease prevalence is 1%, the Positive Predictive Value (PPV) is approximately:
- A) 90%
- B) 4.3%
- C) 80%
- D) 50%
Answer: B - PPV = (Sensitivity × Prevalence) / [(Sensitivity × Prevalence) + ((1-Specificity) × (1-Prevalence))]. With low prevalence (1%), PPV drops dramatically to ~4.3%. This illustrates why mass screening in low-prevalence populations generates many false positives.
Q8. The "Attributable Risk Percent" (AR%) in exposed individuals represents:
- A) Proportion of disease in the general population due to exposure
- B) Proportion of disease among exposed people that is due to the specific exposure
- C) Excess risk in the total population due to exposure
- D) Ratio of incidence in exposed to unexposed
Answer: B - AR% (Etiologic fraction) = [(RR - 1) / RR] × 100. It tells what proportion of disease in the exposed group would be eliminated if exposure were removed.
Q9. The "Berkson's bias" is specifically a type of bias seen in:
- A) Prospective cohort studies
- B) Community-based case-control studies
- C) Hospital-based case-control studies
- D) Randomized controlled trials
Answer: C - Berkson's bias occurs in hospital-based studies because hospitalized controls have different exposure patterns than the general population, making them unrepresentative.
Q10. During outbreak investigation, the FIRST step after confirmation of an outbreak is:
- A) Identify the source of infection
- B) Establish a case definition
- C) Draw an epidemic curve
- D) Implement control measures
Answer: B - The sequence in outbreak investigation: confirm outbreak → establish case definition → find cases (case count) → describe by time, place, person → draw epidemic curve → identify source → implement control.
IMMUNIZATION & NATIONAL IMMUNIZATION PROGRAMME (Q 11-20)
Q11. As per Universal Immunization Programme (UIP), the Oral Polio Vaccine (OPV) given at birth is called:
- A) Primary dose
- B) Zero dose
- C) Booster dose
- D) Supplementary dose
Answer: B - OPV given at birth (along with Hepatitis B birth dose) is termed the "Zero dose" because it is given before the primary series begins at 6 weeks.
Q12. The Vaccine Vial Monitor (VVM) changes color from light to dark when:
- A) Vaccine has been frozen
- B) Vaccine has been exposed to excessive heat
- C) Vaccine has expired
- D) Vaccine vial has been opened for >4 hours
Answer: B - VVM is a heat-sensitive label that changes color irreversibly when cumulative heat exposure is excessive. It does NOT detect freezing damage.
Q13. Which vaccine is MOST sensitive to freezing damage?
- A) OPV
- B) BCG
- C) Hepatitis B vaccine
- D) Measles vaccine
Answer: C - Freeze-sensitive vaccines include: DPT, TT, Hepatitis B, DT, and liquid formulations of Hib. OPV, BCG, and measles are NOT damaged by freezing. Hepatitis B is particularly sensitive to freezing ("shake test" is used to detect freeze damage).
Q14. Under the Universal Immunization Programme, at what age is the 2nd dose of Measles-Rubella (MR) vaccine given?
- A) 6 months
- B) 9 months
- C) 15 months
- D) 16-24 months
Answer: D - MR vaccine: 1st dose at 9-12 months; 2nd dose at 16-24 months. This replaced the earlier practice of giving measles vaccine only once.
Q15. The "Ice-Lined Refrigerator" (ILR) used in the cold chain can maintain cold temperature (2-8°C) without electricity for a minimum of:
- A) 2 hours
- B) 4 hours
- C) 8 hours
- D) 12 hours
Answer: C - ILR can keep vaccines safe with a minimum of 8 hours continuous electricity supply in a 24-hour period. Its top-opening design holds cold air better than front-opening refrigerators.
Q16. Which vaccine is stored at -15°C to -25°C at the state and district levels but at 2-8°C at the peripheral level?
- A) BCG
- B) Hepatitis B
- C) OPV
- D) Rotavirus vaccine
Answer: C - OPV requires -15°C to -25°C at regional/state/district cold chain points. At the PHC/subcentre level it is stored at 2-8°C and must be used within the specified time.
Q17. AEFI stands for:
- A) Adverse Events Following Immunization
- B) Acute Episodes of Febrile Illness
- C) Adverse Effects of Foreign Immunogens
- D) Acute Encephalitis Following Injection
Answer: A - AEFI = Adverse Events Following Immunization. These are categorized as: vaccine product-related, vaccine quality defect-related, immunization error-related, immunization anxiety-related, or coincidental events.
Q18. The "Open Vial Policy" for reusing opened vaccine vials applies to all of the following EXCEPT:
- A) OPV
- B) BCG
- C) Measles vaccine (reconstituted)
- D) DPT
Answer: C - Reconstituted vaccines (BCG, measles, MR, JE) must be discarded after 4 hours or at end of session. Multi-dose vials of OPV, DPT, DT, TT, and Hepatitis B can be reused for up to 4 weeks under open vial policy if VVM is intact, stored correctly, and not contaminated.
Q19. The "Pulse Polio Immunization" strategy specifically aims to achieve:
- A) Routine immunization coverage
- B) High simultaneous coverage to interrupt wild poliovirus transmission
- C) Immunization of hospitalized children only
- D) Immunization of children above 5 years
Answer: B - Pulse Polio Immunization (National Immunization Days - NIDs) gives OPV to all children 0-5 years on specific days nationwide to achieve high simultaneous coverage and rapidly interrupt wild poliovirus circulation by boosting community (herd) immunity.
Q20. Pentavalent vaccine used in UIP protects against:
- A) Diphtheria, Tetanus, Pertussis, Hib, Hepatitis B
- B) Diphtheria, Tetanus, Pertussis, Hib, Polio
- C) Diphtheria, Tetanus, Pertussis, Hepatitis B, Polio
- D) Diphtheria, Tetanus, Measles, Hib, Hepatitis B
Answer: A - Pentavalent vaccine = DPT + Hib (Haemophilus influenzae type b) + Hepatitis B. Given at 6, 10, and 14 weeks. It replaced the separate DPT and Hepatitis B injections.
NATIONAL HEALTH PROGRAMS (Q 21-30)
Q21. Under the Revised National Tuberculosis Control Programme (RNTCP)/National TB Elimination Programme (NTEP), the treatment category for previously treated TB cases (smear-positive relapse, failure, or treatment after default) is:
- A) Category I
- B) Category II
- C) Category III
- D) Category IV
Answer: B - Category II (2HRZES/1HRZE/5HRE) was used for re-treatment cases. Under NTEP, this has been replaced by individualized shorter MDR-TB regimens, but Category II remains a frequently tested NORCET topic.
Q22. The "DOTS" strategy in RNTCP ensures treatment compliance primarily through:
- A) Daily home visits by ASHA workers
- B) Direct observation of each dose swallowing by a treatment supporter
- C) Self-administered outpatient therapy with pill counting

- C) (Blood slides positive for malaria / Total population) × 1000
- D) (Malaria deaths / Total malaria cases) × 100
Answer: C - API = (Total confirmed malaria cases in a year / Mid-year population) × 1000. High-risk areas are defined as API ≥ 2. It is the most important indicator for malaria program monitoring.
MATERNAL AND CHILD HEALTH (Q 31-37)
Q31. As per WHO, "Maternal Mortality Ratio" (MMRatio) is defined as:
- A) Maternal deaths per 1,000 women of reproductive age per year
- B) Maternal deaths per 100,000 live births
- C) Maternal deaths per 1,000 total births
- D) Maternal deaths per 1,000 women aged 15-49 years
Answer: B - MMRatio = (Maternal deaths / Live births) × 100,000. A "maternal death" is death of a woman during pregnancy or within 42 days of termination of pregnancy from any cause related to or aggravated by the pregnancy.
Q32. The "Three Delays Model" in maternal mortality refers to delays in:
- A) Diagnosis, treatment, and discharge
- B) Deciding to seek care, reaching care, and receiving care
- C) Antenatal, intranatal, and postnatal care
- D) Government policy, community awareness, and health facility readiness
Answer: B - Three Delays Model (Thaddeus and Maine, 1994): Delay 1 - deciding to seek care (sociocultural, economic factors); Delay 2 - reaching appropriate care facility (transport, distance); Delay 3 - receiving adequate care (quality of care at facility).

Q40. The "incubation period" for rabies ranges from:
- A) 1-7 days
- B) 10-14 days
- C) 10 days to several years (usually 2-8 weeks)
- D) 3-6 months only
Answer: C - Rabies incubation period is extremely variable: 10 days to 7+ years (usually 2-8 weeks). It depends on the site and severity of bite (head/face bites have shorter incubation), and the viral load.
Q41. Under the National AIDS Control Programme (NACP), "Bridge population" refers to:
- A) HIV-infected blood donors
- B) Healthcare workers with needle-stick injuries
- C) Groups like truck drivers, migrant workers who link high-risk and general populations
- D) Intravenous drug users
Answer: C - Bridge populations are groups that connect high-risk populations (CSWs, MSM, IDUs) to the general population, including truckers, migrant workers, clients of sex workers. They are a key target for HIV prevention interventions.
Q42. In dengue fever, "Warning signs" that indicate progression to severe dengue include all of the following EXCEPT:
- A) Abdominal pain and tenderness
- B) Persistent vomiting
- C) Rapid breathing (tachypnea) without pleural effusion
- D) Clinical fluid accumulation (pleural effusion, ascites)
Answer: C - WHO 2009 dengue warning signs: abdominal pain/tenderness, persistent vomiting, clinical fluid accumulation, mucosal bleeding, lethargy/restlessness, liver enlargement >2cm, rising hematocrit with rapid platelet decline. Rapid breathing alone (without fluid accumulation) is NOT a specific dengue warning sign.

- A) 24-72 hours
- B) 4-12 days
- C) 3-12 weeks (window period)
- D) 6-12 months
Answer: C - The "window period" (time from HIV infection to detectable antibodies) is typically 3-12 weeks with 4th generation tests (antigen/antibody combo). During this period, the person is infectious but tests negative on standard antibody tests.
Q44. The "Sputum Grading" system in tuberculosis: a smear is graded as "3+" when:

- B) 10-99 AFB per 100 fields
- C) 1-10 AFB per field in at least 50 fields
- D) >10 AFB per field in at least 20 fields
Answer: D - AFB smear grading (Ziehl-Neelsen): Scanty = 1-9 bacilli per 100 fields; 1+ = 10-99 per 100 fields; 2+ = 1-10 per field (in ≥50 fields); 3+ = >10 per field (in ≥20 fields).
ENVIRONMENTAL HEALTH & WATER SANITATION (Q 45-50)
Q45. The "Breakpoint chlorination" of water refers to:
- A) The minimum chlorine dose needed to kill bacteria
- B) The point beyond which further chlorine addition produces free residual chlorine
- C) The maximum permissible chlorine level in drinking water
- D) The dose at which chlorine becomes toxic to humans
Answer: B - Breakpoint chlorination: as chlorine is added, it first reacts with organic matter and ammonia (forming chloramines). The "breakpoint" is reached when all chlorine-demanding substances are satisfied; chlorine added beyond this point remains as free residual chlorine (the effective disinfectant).
Q46. The "Millipore filter test" for water quality detects:
- A) Total dissolved solids
- B) Coliform bacteria (E. coli)
- C) Chemical contaminants
- D) Turbidity
Answer: B - The Millipore (membrane) filter test is a standard bacteriological method to detect and count coliform bacteria (indicator of fecal contamination) in water samples. It is more sensitive than the Multiple Tube (MPN) method.
Q47. A village has 500 houses and a total population of 2500. The community health nurse finds 50 houses with Aedes aegypti larvae positive containers. The "House Index" (HI) is:
- A) 5%
- B) 10%
- C) 20%
- D) 2%
Answer: B - House Index = (Number of houses with Aedes larvae / Total houses inspected) × 100 = (50 / 500) × 100 = 10%. HI >1% indicates risk of dengue transmission.
Q48. "Minamata disease" is caused by environmental contamination with:
- A) Lead
- B) Cadmium
- C) Methyl mercury
- D) Arsenic
Answer: C - Minamata disease: neurological syndrome caused by methylmercury poisoning (from industrial effluents into Minamata Bay, Japan, bioaccumulated in fish). Features: sensory disturbances, ataxia, vision/hearing loss, tremors. Itai-Itai disease = cadmium. Fluorosis = fluoride.
Q49. Under National Environmental Health Standards, the permissible limit of FLUORIDE in drinking water in India is:
- A) 0.5 mg/L
- B) 1.0 mg/L
- C) 1.5 mg/L
- D) 2.0 mg/L
Answer: C - The Bureau of Indian Standards (BIS) and WHO set the permissible limit of fluoride in drinking water at 1.5 mg/L. The desirable limit is 1.0 mg/L. >1.5 mg/L causes dental fluorosis; >3 mg/L causes skeletal fluorosis.
Q50. A community health nurse is evaluating the efficiency of a waste management system. "Calorific value" of municipal solid waste is important for determining its suitability for:
- A) Composting
- B) Sanitary landfill
- C) Incineration
- D) Vermicomposting
Answer: C - Calorific value (heat content) of waste is the primary determinant for incineration feasibility. For efficient incineration without auxiliary fuel, the calorific value should be at least 1000 kcal/kg. Incineration is the method of choice for biomedical/hospital waste.
