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 correct answer is C: Measles, Mumps, Rubella (MMR) vaccine. Live attenuated vaccines contain weakened forms of the virus. MMR vaccine is made from weakened live viruses of measles, mumps, and rubella. When administered, the body develops an immune response without causing the disease. Choice A, Hepatitis B vaccine, is a subunit vaccine. Choice B, Inactivated polio vaccine, is a killed virus vaccine. Choice D, Diphtheria, Tetanus, Pertussis (DPT) vaccine, is a toxoid vaccine. Live attenuated vaccines provide stronger and longer-lasting immunity as they mimic natural infection without causing illness.

Which of the following is an example of a waterborne disease?
- A. Hepatitis A
- B. Influenza
- C. Measles
- D. Tuberculosis
Correct Answer: A
Rationale: The correct answer is A: Hepatitis A. Waterborne diseases are caused by pathogens that are transmitted through contaminated water. Hepatitis A is a viral infection that spreads through the consumption of contaminated water or food. It affects the liver and is commonly associated with poor sanitation and hygiene. Influenza, Measles, and Tuberculosis are not waterborne diseases. Influenza and Measles are viral infections spread through respiratory droplets, while Tuberculosis is a bacterial infection primarily transmitted through the air. Hepatitis A is the only choice that aligns with the definition of a waterborne disease.
What is the main focus of the World Health Organization's (WHO) Health For All strategy?
- A. Providing free healthcare to all individuals
- B. Achieving a level of health that enables all people to lead economically productive lives
- C. Building more hospitals and clinics
- D. Increasing the number of healthcare workers
Correct Answer: B
Rationale: The correct answer is B: Achieving a level of health that enables all people to lead economically productive lives. This is the main focus of WHO's Health For All strategy as it aims to ensure that individuals have good health to actively participate in society and the economy. Choice A is incorrect as the strategy doesn't necessarily focus on providing free healthcare to all individuals, but rather on improving overall health outcomes. Choice C is incorrect as simply building more hospitals and clinics does not address the holistic approach of the Health For All strategy. Choice D is incorrect as increasing the number of healthcare workers is important, but the main focus is on achieving better health outcomes for economic productivity.
Which of the following is NOT a component of Primary Health Care (PHC)?
- A. Community participation
- B. Use of appropriate technology
- C. Equitable distribution of resources
- D. Exclusive focus on curative care
Correct Answer: D
Rationale: The correct answer is D: Exclusive focus on curative care. Primary Health Care (PHC) emphasizes preventive, promotive, and rehabilitative services rather than solely focusing on curative care. Curative care is just one aspect of healthcare but not the sole focus of PHC. Community participation (A), use of appropriate technology (B), and equitable distribution of resources (C) are all essential components of PHC as they contribute to comprehensive and accessible healthcare for all.
What is the primary purpose of conducting a health survey in a community?
- A. To provide medical treatment to individuals
- B. To gather data on health status and needs
- C. To distribute health education materials
- D. To perform laboratory tests
Correct Answer: B
Rationale: The correct answer is B: To gather data on health status and needs. The primary purpose of conducting a health survey in a community is to systematically collect information on the health of the population, identify health issues, assess needs, and guide healthcare planning. This data helps in developing effective public health interventions and policies.
Choice A (To provide medical treatment to individuals) is incorrect because health surveys focus on population-level data collection, not individual treatment. Choice C (To distribute health education materials) is incorrect as the primary purpose of a health survey is data collection, not distribution of materials. Choice D (To perform laboratory tests) is incorrect because health surveys typically involve collecting information through questionnaires and interviews, rather than conducting laboratory tests.
What is the primary purpose of administering Vitamin K to newborns?
- A. To prevent infection
- B. To promote growth
- C. To prevent bleeding disorders
- D. To enhance immune function
Correct Answer: C
Rationale: The primary purpose of administering Vitamin K to newborns is to prevent bleeding disorders. Vitamin K is essential for the production of blood clotting factors, which helps prevent excessive bleeding. Newborns are born with low levels of Vitamin K, putting them at risk for bleeding disorders like vitamin K deficiency bleeding. Administering Vitamin K at birth helps ensure proper blood clotting function. The other choices are incorrect because Vitamin K does not directly prevent infection, promote growth, or enhance immune function in newborns.
