1. What is the primary method of transmission for tuberculosis?

A. Vector-borne
B. Airborne
C. Waterborne
D. Fecal-oral

Correct answer: B

Rationale: The correct answer is 'Airborne.' Tuberculosis is mainly transmitted through the air via respiratory droplets when an infected person coughs or sneezes. This allows the bacteria to be inhaled by others and infect their lungs. It is important to implement infection control measures to prevent the spread of tuberculosis in healthcare settings and the community.

2. Which of the following is a function of epidemiology?

A. Identifying disease conditions based on manifestations presented by a client
B. Determining factors that contributed to the occurrence of pneumonia in a 3-year-old
C. Determining the efficacy of the antibiotic used in the treatment of the 3-year-old client with pneumonia
D. Evaluating the effectiveness of the implementation of the Integrated Management of Childhood Illness

Correct answer: D

Rationale: The function of epidemiology includes evaluating the effectiveness of interventions, programs, or policies implemented to improve public health outcomes. In this context, epidemiology aids in assessing the impact and success of strategies like the Integrated Management of Childhood Illness in community health practice.

3. Which numerator is used in computing the general fertility rate?

A. Estimated midyear population
B. Number of registered live births
C. Number of pregnancies in the year
D. Number of females of reproductive age

Correct answer: B

Rationale: The general fertility rate is calculated by dividing the number of registered live births by the number of females of reproductive age (usually 15-45 years) and then multiplying the result by 1,000. This rate helps in understanding the average number of live births a woman in a specific population is expected to have during her reproductive years.

4. Which of the following is an example of a live attenuated vaccine?

A. Hepatitis B vaccine
B. Inactivated polio vaccine
C. Measles, Mumps, Rubella (MMR) vaccine
D. Diphtheria, Tetanus, Pertussis (DPT) vaccine

Correct answer: C

Rationale: The Measles, Mumps, Rubella (MMR) vaccine is an example of a live attenuated vaccine because it contains weakened versions of the viruses that cause measles, mumps, and rubella. These weakened viruses can replicate in the body to stimulate an immune response without causing the diseases themselves.

5. Which statistic best reflects the nutritional status of a population?

A. 1-4 year old age-specific mortality rate
B. Proportionate mortality rate
C. Infant mortality rate
D. Swaroop’s index

Correct answer: A

Rationale: The most appropriate statistic to reflect the nutritional status of a population is the 1-4 year old age-specific mortality rate. This age group is highly susceptible to the effects of malnutrition, so a population with poor nutritional status is likely to have a high 1-4 year old age-specific mortality rate, also known as child mortality rate.
