What is the purpose of a population pyramid?

Correct Answer: B

Rationale: The correct answer is B: To illustrate the age and sex composition of a population. Population pyramids graphically represent the age and gender structure of a population, showing the distribution of different age groups and genders within a population at a specific point in time. This information is crucial for policymakers and demographers to understand population dynamics, such as birth rates, life expectancy, and potential workforce size. Choice A (To show the distribution of income levels) is incorrect because income levels are not typically depicted in a population pyramid. Choice C (To compare the incidence of diseases) is incorrect because population pyramids do not provide information on disease prevalence. Choice D (To display the literacy rates) is incorrect as literacy rates are also not typically included in population pyramids.

Correct Answer: C

Rationale: The correct answer is C: Infant mortality rate. This indicator reflects the number of infants who die before reaching one year of age per 1,000 live births. It is a crucial measure of the overall health of a population as it reflects the quality of healthcare, nutrition, and living conditions. High infant mortality rates indicate poor health outcomes and inadequate healthcare services. A: Literacy rate is not directly related to measuring the health status of a population. B: GDP measures the economic performance of a country and does not directly reflect the health status of its population. D: Employment rate is an indicator of the labor market situation, not specifically related to health status measurement.

Correct Answer: B

Rationale: The correct answer is B: Previous allergic reaction to the vaccine. This is a contraindication for live vaccines because individuals with a history of allergic reactions to a specific vaccine are at a higher risk of developing severe allergic reactions upon re-administration. It is crucial to avoid administering live vaccines to these individuals to prevent potential life-threatening complications. Incorrect Choices: A: Mild upper respiratory infection - This is not a contraindication for live vaccines as it is a mild and temporary condition that does not affect vaccine administration. C: Current antibiotic therapy - This is not a contraindication for live vaccines as antibiotics do not interfere with live vaccine effectiveness. D: Family history of allergies - While a family history of allergies may increase the risk of developing allergies, it is not a direct contraindication for live vaccines as long as the individual themselves does not have a history of allergic reactions to the specific vaccine.

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.

Correct Answer: A

Rationale: The correct answer is A: Frequent handwashing. Handwashing is essential for preventing the spread of healthcare-associated infections as it helps remove and kill harmful bacteria and viruses. By washing hands regularly, healthcare workers can reduce the risk of transmitting infections between patients. Sharing medical equipment (B) can actually increase the spread of infections. Reducing patient turnover (C) can help minimize exposure, but without proper hand hygiene, infections can still spread. Increasing hospital bed capacity (D) is unrelated to preventing infections. Therefore, A is the most effective practice for infection control.

Correct Answer: B

Rationale: The correct answer is B: To illustrate the age and sex composition of a population. Population pyramids graphically represent the age and gender structure of a population, showing the distribution of different age groups and genders within a population at a specific point in time. This information is crucial for policymakers and demographers to understand population dynamics, such as birth rates, life expectancy, and potential workforce size. Choice A (To show the distribution of income levels) is incorrect because income levels are not typically depicted in a population pyramid. Choice C (To compare the incidence of diseases) is incorrect because population pyramids do not provide information on disease prevalence. Choice D (To display the literacy rates) is incorrect as literacy rates are also not typically included in population pyramids.

Correct Answer: B

Rationale: The correct answer is B: Community participation. This is a key principle of Primary Health Care (PHC) as it emphasizes involving communities in decision-making, planning, and implementation of healthcare services. Community participation ensures that healthcare services are culturally appropriate, accessible, and meet the specific needs of the population. It also promotes empowerment and ownership of health initiatives within the community. Centralized health planning (A) goes against the decentralized and community-focused approach of PHC. Focus on specialized care (C) contradicts the comprehensive and holistic nature of PHC. High technology healthcare (D) may not always be feasible or accessible in resource-limited settings, which is a key consideration in PHC implementation.

Correct Answer: C

Rationale: The primary goal of the Integrated Management of Childhood Illness (IMCI) strategy is to reduce child mortality and morbidity. This strategy focuses on providing holistic care to children, including early detection and treatment of common childhood illnesses. By improving healthcare access and quality, IMCI aims to decrease the number of children dying from preventable diseases. Explanation: A: Reducing the incidence of childhood diseases is important but not the primary goal of IMCI. The strategy is more focused on reducing mortality and morbidity. B: Improving nutritional status is essential for child health but is not the primary goal of IMCI. D: Promoting exclusive breastfeeding is a key component of child health but is not the primary goal of IMCI.

Correct Answer: C

Rationale: The correct answer is C: 12 months. The first dose of the MMR vaccine is typically administered at 12 months of age because this is when a child's immune system is more developed to respond effectively to the vaccine. Administering it earlier may not provide adequate protection. Choice A (At birth) is incorrect because newborns have maternal antibodies that can interfere with the vaccine's efficacy. Choice B (6 months) is too early as infants need time to develop their immune system. Choice D (18 months) is also incorrect as delaying the vaccine may leave the child vulnerable to diseases like measles, mumps, and rubella.
