1. Which is a characteristic of person-to-person propagated epidemics?

Correct answer: D

Rationale: In person-to-person propagated epidemics, there is typically a gradual build-up of cases before the epidemic becomes easily noticeable. This slow onset allows for the disease to spread from one individual to another, leading to a progressive increase in cases over time.

2. Which of the following is an essential nutrient required for preventing neural tube defects?

Correct answer: D

Rationale: Folic acid is a crucial nutrient required for preventing neural tube defects during pregnancy. It plays a vital role in the development of the neural tube in the fetus, reducing the risk of defects such as spina bifida and anencephaly. It is recommended that women of childbearing age consume adequate amounts of folic acid, either through diet or supplements, to support a healthy pregnancy and prevent these serious birth defects.

5. Sputum examination is the major screening tool for pulmonary tuberculosis. Clients may sometimes receive false negative results in this exam. This means that the test is not perfect in terms of which characteristic of a diagnostic examination?

Correct answer: D

Rationale: Sensitivity is the ability of a diagnostic test to correctly identify individuals with the disease. A test with high sensitivity will rarely give false negative results, as it will detect almost all positive cases. In the context of the given scenario, false negative results indicate that the test is lacking in sensitivity to pick up all cases of pulmonary tuberculosis, leading to some cases being missed.
