Which of the following federal agencies should a community health nurse seek guidance from regarding a public building that has asbestos leaking from rips in the heating duct insulation?
National Institutes of Health
Environmental Protection Agency
Centers for Disease Control and Prevention
Department of Health and Human Services
The Correct Answer is B
Choice A reason: This statement is not the best answer, as the National Institutes of Health (NIH) is not the primary agency responsible for regulating or enforcing environmental standards. The NIH is a research agency that supports biomedical and public health research.
Choice B reason: This statement is the best answer, as the Environmental Protection Agency (EPA) is the federal agency that protects human health and the environment by setting and enforcing standards for air, water, and land quality. The EPA regulates the use, disposal, and cleanup of asbestos, a known carcinogen and health hazard.
Choice C reason: This statement is not the best answer, as the Centers for Disease Control and Prevention (CDC) is not the primary agency responsible for regulating or enforcing environmental standards. The CDC is a public health agency that monitors and responds to disease outbreaks, conducts research, and provides health information.
Choice D reason: This statement is not the best answer, as the Department of Health and Human Services (HHS) is not the primary agency responsible for regulating or enforcing environmental standards. The HHS is a cabinet-level department that oversees various health and human services programs and agencies, such as the NIH, the CDC, and the Food and Drug Administration.

Correct Answer is C
Explanation
A. Echinacea has anti-inflammatory properties that can help reduce pain and swelling associated with arthritis. Studies have shown that echinacea can be effective in managing inflammatory conditions like arthritis, making this a likely indicator of its effectiveness.
B. While echinacea may have some calming effects, it is not primarily used to treat sleep disorders. Therefore, improved sleep is not a direct indicator of echinacea's effectiveness.
C. Echinacea is known for its immune-boosting properties, which can aid in wound healing. However, this is not its primary use, and other factors could contribute to wound healing.
D. Echinacea does not have a significant impact on blood pressure. Therefore, a change in blood pressure is not an indicator of its effectiveness.
Correct Answer is A
Explanation
Choice A reason: This statement is true and relevant. The prevalence proportion is the number of existing cases of a disease divided by the total population at risk. In this case, the existing cases of diabetes mellitus are 11 (6 new cases plus 5 old cases), and the total population at risk is 15,000. Therefore, the prevalence proportion is 11/15,000, which can be simplified to 0.00073 or 0.073%.
Choice B reason: This statement is false and misleading. The prevalence proportion is not calculated by using only the new cases of a disease, but by using the total number of existing cases. Using only the new cases would result in an underestimation of the prevalence proportion.
Choice C reason: This statement is false and misleading. The prevalence proportion is not calculated by using the difference between the total population and the existing cases of a disease, but by using the total population at risk. Using the difference would result in an overestimation of the prevalence proportion.
Choice D reason: This statement is false and misleading. The prevalence proportion is not calculated by using both the difference between the total population and the existing cases of a disease and the new cases of a disease, but by using the total number of existing cases and the total population at risk. Using both the difference and the new cases would result in an incorrect calculation of the prevalence proportion.
