Question 1 of 5
Estimate the number of infants in the barangay.
Correct Answer: C
Rationale: The correct answer is C (55). To estimate the number of infants in the barangay, we need to consider a reasonable average number of infants per household. Assuming an average household size of 4, with about 2 adults and 2 children, we can estimate that roughly 25% of households may have infants. With a total of 220 households in the barangay, 25% of 220 is 55, making C the most reasonable estimate. Summary of other choices: A: 45 - This is on the lower side and underestimates the number of infants. B: 50 - Similar to A, it underestimates the number of infants. D: 60 - This is on the higher side and overestimates the number of infants.
Question 2 of 5
The pathognomonic sign of measles is Koplik's spot. You may see Koplik's spot by inspecting the:
Correct Answer: B
Rationale: The correct answer is B: Buccal mucosa. Koplik's spots are small white spots surrounded by a red halo that appear on the buccal mucosa opposite the molars. This is a pathognomonic sign of measles due to the presence of the measles virus in the mucous membranes. Inspecting the nasal mucosa (Choice A) would not reveal Koplik's spots. Similarly, examining the skin on the abdomen (Choice C) or the skin on the antecubital surface (Choice D) would not show Koplik's spots as they are specific to the buccal mucosa.
Question 3 of 5
Among children aged 2 months to 3 years, the most prevalent form of meningitis is caused by which microorganism?
Correct Answer: A
Rationale: The correct answer is A: Hemophilus Influenzae. In children aged 2 months to 3 years, Hemophilus Influenzae type B (Hib) is the most prevalent cause of meningitis due to their immature immune systems. Hib vaccination has significantly reduced the incidence of Hib meningitis. Morbillivirus (B) causes measles, not meningitis. Streptococcus Pneumoniae (C) and Neisseria meningitidis (D) can also cause meningitis but are less common in this age group compared to Hib.
Question 4 of 5
Mosquito-borne diseases are prevented mostly with the use of mosquito control measures. Which of the following is NOT appropriate for malaria control?
Correct Answer: D
Rationale: The correct answer is D because using mosquito-repelling soaps is not an effective method for malaria control. Malaria is primarily spread through the bites of infected mosquitoes, so focusing on preventing mosquito breeding and bites is key. Let's break it down: A - Chemically treated nets prevent mosquito bites, reducing malaria transmission. B - Introducing larva-eating fish can reduce mosquito populations by eating mosquito larvae. C - Destroying breeding sites eliminates mosquito breeding grounds, reducing the mosquito population and the risk of malaria transmission. D - Mosquito-repelling soaps may help to repel mosquitoes temporarily but do not address the root cause of malaria transmission.
Question 5 of 5
In the Philippines, which specie of schistosoma is endemic in certain regions?
Correct Answer: B
Rationale: Step-by-step rationale: 1. S. japonicum is endemic in the Philippines based on historical data and prevalence studies. 2. S. mansoni is not endemic in the Philippines; it is commonly found in Africa and South America. 3. S. malayensis is a fictional species and does not exist in reality. 4. S. haematobium is primarily found in Africa and the Middle East, not in the Philippines. Summary: The correct answer is B (S. japonicum) because it is the species known to be endemic in certain regions of the Philippines. Choices A, C, and D are incorrect because S. mansoni is not endemic, S. malayensis is fictional, and S. haematobium is not found in the Philippines.
