Which vaccine is typically administered to newborns within the first 24 hours of birth?

Correct Answer: A

Rationale: The correct answer is A: Hepatitis B. Newborns are typically administered the Hepatitis B vaccine within the first 24 hours of birth to prevent transmission from infected mothers. This early vaccination helps protect infants from a potentially serious viral infection. The other choices are incorrect because BCG is usually given for tuberculosis, OPV is an oral polio vaccine, and Measles vaccination is typically given at a later age. Administering Hepatitis B vaccine to newborns is a crucial preventive measure against a common viral infection transmitted from mother to child.

Correct Answer: C

Rationale: The correct answer is C: Vaccination. Vaccination is the most effective method for preventing the spread of infectious diseases because it helps build immunity against specific pathogens, reducing the likelihood of infection and transmission. Vaccines train the immune system to recognize and fight off harmful microorganisms. Antibiotic treatment (A) is used to treat bacterial infections, not prevent the spread of diseases. Quarantine (B) is effective in isolating infected individuals but does not prevent the initial spread of diseases. Nutritional supplementation (D) can support overall health but is not a direct method for preventing infectious diseases.

Correct Answer: C

Rationale: The correct answer is C: To prevent bleeding disorders. Newborns have low levels of Vitamin K, which is essential for blood clotting. Administering Vitamin K at birth helps prevent a rare but serious condition called Vitamin K deficiency bleeding. Choice A is incorrect because Vitamin K does not prevent jaundice. Choice B is incorrect as Vitamin K does not boost the immune system. Choice D is incorrect as Vitamin K does not enhance bone development. Administering Vitamin K to newborns is crucial for preventing bleeding issues.

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: C

Rationale: The correct answer is C: Iron. Iron is essential for preventing anemia in pregnant women because it is a key component of hemoglobin, the protein in red blood cells that carries oxygen to tissues and organs. During pregnancy, the demand for iron increases to support the growing fetus and the mother's increased blood volume. Without adequate iron intake, pregnant women are at a higher risk of developing iron-deficiency anemia, which can lead to complications for both the mother and the baby. Other choices are incorrect because: A: Vitamin C is important for iron absorption but does not directly prevent anemia. B: Vitamin D is important for bone health but does not prevent anemia. D: Calcium is important for bone health but does not prevent anemia in pregnant women.

Correct Answer: D

Rationale: The correct answer is D: Focusing solely on curative care. The Maternal and Child Health (MCH) program aims to prevent illness and promote health in pregnant women, mothers, infants, and children. Focusing solely on curative care does not align with the preventive and promotive goals of the MCH program. Reducing infant mortality, improving maternal health, and providing family planning services are integral components of the MCH program that aim to enhance the overall well-being of mothers and children. By emphasizing prevention and health promotion, the MCH program aims to address the root causes of health issues rather than solely focusing on treating illnesses after they occur.

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: D

Rationale: The correct answer is D: Integrated case management of childhood illnesses. This is a key component of the IMCI (Integrated Management of Childhood Illness) strategy, which focuses on a holistic approach to managing common childhood illnesses at the primary healthcare level. IMCI includes assessing and classifying sick children, providing appropriate treatments, counseling caregivers, and ensuring follow-up care. This strategy aims to reduce childhood morbidity and mortality by improving the quality of care provided to children. Choices A, B, and C are incorrect as they do not directly align with the key component of the IMCI strategy. Promoting hospital-based care (A) may not be feasible or sustainable in resource-limited settings where primary healthcare is crucial. Providing routine immunizations (B) is important but is not the primary focus of the IMCI strategy. Enhancing maternal nutrition (C) is essential for maternal and child health but is not a key component of the IMCI strategy, which specifically targets childhood illnesses.

Correct Answer: C

Rationale: Tertiary prevention focuses on managing and improving quality of life for individuals with existing health conditions. Physical rehabilitation programs fall under this category as they help individuals recover and regain functioning after an illness or injury. This intervention aims to prevent further complications and disabilities. Vaccination campaigns (A) and health education seminars (B) are examples of primary and secondary prevention, focusing on preventing diseases before they occur or detecting them early. Early disease screening (D) is also a form of secondary prevention, aiming to detect diseases in their early stages before symptoms appear.
