Sample Question 1
Community Medicine & Public Health
Easy • Medical Sciences
Under the Expanded Programme on Immunization (EPI) in Pakistan, which vaccine is administered at birth along with OPV-0 and Hepatitis B?
A
Measles
B
BCG (Bacille Calmette-Guérin)
C
Pentavalent
D
PCV (Pneumococcal)
✓ Correct Answer: B - BCG (Bacille Calmette-Guérin)
📖 Step-by-Step Solution & Conceptual Rationale:
At birth, infants in Pakistan receive BCG (intradermal, against tuberculosis), Oral Polio Vaccine (OPV-0), and the birth dose of Hepatitis B vaccine.
Sample Question 2
Community Medicine & Public Health
Easy • Medical Sciences
The Pentavalent vaccine in Pakistan's EPI schedule provides combined protection against which five infectious diseases?
A
Polio, Measles, Rubella, Mumps, Tuberculosis
B
Diphtheria, Pertussis, Tetanus, Hepatitis B, and Haemophilus influenzae type b (Hib)
C
Diphtheria, Tetanus, Pertussis, Polio, Rotavirus
D
TB, Cholera, Typhoid, Tetanus, Hepatitis A
✓ Correct Answer: B - Diphtheria, Pertussis, Tetanus, Hepatitis B, and Haemophilus influenzae type b (Hib)
📖 Step-by-Step Solution & Conceptual Rationale:
Pentavalent vaccine immunizes against Diphtheria, Pertussis (whooping cough), Tetanus, Hepatitis B, and Haemophilus influenzae type b (Hib), administered at 6, 10, and 14 weeks.
Sample Question 3
Community Medicine & Public Health
Easy • Medical Sciences
Which vector is responsible for the transmission of Dengue virus, Chikungunya, and Zika virus in Pakistan?
A
Anopheles stephensi
B
Aedes aegypti (and Aedes albopictus)
C
Culex quinquefasciatus
D
Phlebotomus sandfly
✓ Correct Answer: B - Aedes aegypti (and Aedes albopictus)
📖 Step-by-Step Solution & Conceptual Rationale:
Aedes mosquitoes (primarily Aedes aegypti) are day-biting vectors that breed in clean, artificial water collections and transmit Dengue, Yellow fever, Chikungunya, and Zika.
Sample Question 4
Community Medicine & Public Health
Medium • Medical Sciences
In epidemiology, the proportion of truly diseased individuals who test positive on a screening test is termed:
A
Specificity
B
Sensitivity
C
Positive predictive value (PPV)
D
Likelihood ratio
✓ Correct Answer: B - Sensitivity
📖 Step-by-Step Solution & Conceptual Rationale:
Sensitivity represents true-positive rate: the ability of a screening test to correctly identify individuals who actually possess the disease [TP / (TP + FN)].
Sample Question 5
Community Medicine & Public Health
Medium • Medical Sciences
Which epidemiological study design is best suited for investigating rare diseases or diseases with long latency periods?
A
Cross-sectional survey
B
Case-control study
C
Prospective cohort study
D
Ecological study
✓ Correct Answer: B - Case-control study
📖 Step-by-Step Solution & Conceptual Rationale:
Case-control studies identify individuals with the disease (cases) and without (controls) and look backwards for exposure; they are economical and ideal for studying rare conditions.
Sample Question 6
Community Medicine & Public Health
Easy • Medical Sciences
Maternal Mortality Ratio (MMR) is standardly defined in public health statistics as maternal deaths per how many live births?
A
1,000 live births
B
10,000 live births
C
100,000 live births
D
1,000,000 live births
✓ Correct Answer: C - 100,000 live births
📖 Step-by-Step Solution & Conceptual Rationale:
The Maternal Mortality Ratio is calculated as the number of resident maternal deaths resulting from the pregnancy process per 100,000 live births during a specified year.
Sample Question 7
Community Medicine & Public Health
Medium • Medical Sciences
In municipal water purification, what is the recommended minimum free residual chlorine level required at the consumer's tap after 30 minutes of contact time?
A
0.1 mg/L
B
0.5 mg/L
C
2.0 mg/L
D
5.0 mg/L
✓ Correct Answer: B - 0.5 mg/L
📖 Step-by-Step Solution & Conceptual Rationale:
WHO and national drinking water standards prescribe a minimum free residual chlorine concentration of 0.5 mg/L (ppm) after at least 30 minutes of contact time at pH < 8.0.
Sample Question 8
Community Medicine & Public Health
Easy • Medical Sciences
Which of the following describes 'Cold Chain' in public health practice?
A
Storage of surgical instruments at low temperatures
B
A system of storing and transporting vaccines within the recommended temperature range (+2°C to +8°C) from manufacturer to point of use
C
Cryotherapy for malignant skin lesions
D
Hypothermic cardiac preservation techniques
✓ Correct Answer: B - A system of storing and transporting vaccines within the recommended temperature range (+2°C to +8°C) from manufacturer to point of use
📖 Step-by-Step Solution & Conceptual Rationale:
The vaccine cold chain is a continuous network of refrigerators, cold boxes, and icepacks ensuring potent vaccines are kept between +2°C and +8°C from factory to administration.
Sample Question 9
Community Medicine & Public Health
Medium • Medical Sciences
The definitive diagnostic test for pulmonary tuberculosis endorsed by the WHO for rapid detection of Mycobacterium tuberculosis and rifampicin resistance is:
A
Erythrocyte sedimentation rate (ESR)
B
GeneXpert MTB/RIF assay (nucleic acid amplification)
C
Chest radiograph alone
D
Tuberculin skin test
✓ Correct Answer: B - GeneXpert MTB/RIF assay (nucleic acid amplification)
📖 Step-by-Step Solution & Conceptual Rationale:
GeneXpert MTB/RIF is an automated real-time PCR assay providing simultaneous detection of Mycobacterium tuberculosis and rifampicin-resistance mutations within two hours.
