Question 1 of 5

Which of the following best describes epidemiology?

Correct Answer: B

Rationale: The correct answer is B because epidemiology not only focuses on studying the distribution and determinants of health-related states or events but also emphasizes applying this knowledge to control health problems. Choice A is incorrect because it lacks the application aspect. Choice C is incorrect as it specifically mentions social factors, which is a narrower focus than epidemiology. Choice D is incorrect as it focuses solely on health systems and services, neglecting the broader scope of epidemiology. In summary, choice B aligns with the comprehensive nature of epidemiology by encompassing both study and application aspects.

Question 2 of 5

Which of the following is an example of a non-communicable disease?

Correct Answer: C

Rationale: The correct answer is C: Cancer. Non-communicable diseases are not transmitted from person to person and are often chronic in nature. Cancer is a non-communicable disease characterized by abnormal cell growth. Tuberculosis (A) and Malaria (B) are infectious diseases caused by bacteria and parasites, respectively, and can be transmitted between individuals. Heart disease (D) can have both genetic and lifestyle factors, but it is not communicable. In summary, cancer fits the criteria of being non-communicable, while the other choices involve transmission between individuals.

Rapid fluid and electrolyte replacement is vital to maintain hydration. 4. Oxygen therapy can help support respiratory function in severe cases. 5. Therefore, aspirin for high fever is incorrect due to the bleeding risk.

Question 4 of 5

Directly Observed Treatment Short Course (D.O.T.S.) can do all of the following except:

Correct Answer: C

Rationale: The correct answer is C: Require hospitalization. D.O.T.S. is an outpatient treatment strategy for tuberculosis. Hospitalization is not a requirement for D.O.T.S. as patients receive medication under direct observation in a community setting. This approach helps to ensure medication adherence, stops resistance to anti-TB drugs, cures TB patients, and prevents new infections among children and adults. In summary, D.O.T.S. does not involve hospitalization and is an effective outpatient strategy for TB treatment.

Question 5 of 5

Which of the following statements about TB treatment is INCORRECT?

A: Correct - Combination therapy is essential to prevent drug resistance. C: Correct - Proper treatment leads to cure and non-infectiousness. D: Correct - TB is curable with proper treatment. B: Incorrect - Single drug therapy can lead to drug resistance and treatment failure.
