Which of the following is a common sign of dehydration in infants?
- A. Frequent urination
- B. Sunken fontanelle
- C. Excessive drooling
- D. Increased appetite
Correct Answer: B
Rationale: The correct answer is B: Sunken fontanelle. Dehydration in infants can cause the fontanelle, the soft spot on the baby's head, to appear sunken. This is due to decreased fluid levels in the body. Sunken fontanelle is a common and easily identifiable sign of dehydration in infants. The other choices are incorrect because frequent urination is not typically associated with dehydration in infants, excessive drooling can be a normal part of teething, and increased appetite is not a specific sign of dehydration in infants.

What is the best type of milk for infants below 6 months of age?
- A. Cow's milk
- B. Goat's milk
- C. Breast milk
- D. Soy milk
Correct Answer: C
Rationale: The correct answer is C: Breast milk. Breast milk is the best type of milk for infants below 6 months of age because it provides the ideal nutrition and antibodies necessary for their growth and development. It contains the perfect balance of nutrients, is easily digestible, and helps protect infants from infections and diseases.
Choice A: Cow's milk is not recommended for infants below 6 months as it is difficult for them to digest and lacks essential nutrients like iron and vitamin E.
Choice B: Goat's milk is also not recommended for infants below 6 months as it lacks certain nutrients and may cause allergic reactions.
Choice D: Soy milk is not suitable as a primary source of nutrition for infants below 6 months as it may not provide all the necessary nutrients and can lead to digestive issues.
In summary, breast milk is the best choice for infants below 6 months due to its unique composition and numerous benefits compared to other types of milk.
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 B: Airborne. Tuberculosis is primarily transmitted through the air via droplets released when an infected person coughs or sneezes. These droplets contain the bacteria that cause TB, which can then be inhaled by others and infect their lungs. This mode of transmission is supported by scientific evidence and is the most common way TB spreads.
Choice A: Vector-borne is incorrect because tuberculosis is not transmitted by insects or animals.
Choice C: Waterborne is incorrect as TB is not typically spread through contaminated water.
Choice D: Fecal-oral is incorrect since TB bacteria are not typically found in feces and transmitted through oral ingestion.
Which of the following practices is essential for preventing the spread of healthcare-associated infections?
- A. Frequent handwashing
- B. Sharing medical equipment
- C. Reducing patient turnover
- D. Increasing hospital bed capacity
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.
Which of the following is a key component of the IMCI strategy?
- A. Promoting hospital-based care
- B. Providing routine immunizations
- C. Enhancing maternal nutrition
- D. Integrated case management of childhood illnesses
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.
Which of the following is a key strategy in the prevention of mother-to-child transmission of HIV?
- A. Exclusive breastfeeding
- B. Routine immunization
- C. Antiretroviral therapy
- D. Nutritional supplementation
Correct Answer: C
Rationale: The correct answer is C: Antiretroviral therapy. This is a key strategy because it involves giving HIV medications to the mother during pregnancy, labor, and delivery, as well as to the newborn, significantly reducing the risk of transmission. Antiretroviral therapy helps lower the viral load in the mother's body, making it less likely for the virus to be passed on to the child. Exclusive breastfeeding (choice A) can increase the risk of transmission, routine immunization (choice B) does not directly prevent mother-to-child transmission of HIV, and nutritional supplementation (choice D) is not a primary strategy for preventing transmission.
