Correct Answer: C

Rationale: The correct answer is to wash and rinse the bed linens in hot water to help eliminate dust mites, a common trigger for asthma episodes. Washing in hot water is more effective in killing dust mites compared to warm water. Changing pillow covers every month may help but is not as effective as washing bed linens in hot water. Using air filters in the furnace system may improve air quality but does not directly target dust mites on bed linens.

Correct Answer: D

Rationale: The PPD (purified protein derivative) intradermal test is the standard screening method for detecting tuberculosis infection. It helps identify individuals who have been infected with Mycobacterium tuberculosis. A chest x-ray (Choice A) is used to assess the extent of active disease, not for screening purposes. Blood culture (Choice B) is not typically used for tuberculosis screening. Sputum culture (Choice C) is used to confirm active tuberculosis in symptomatic individuals, not for initial screening purposes.

Correct Answer: D

Rationale: When assessing reimbursement for services from private insurance companies, approval by the network healthcare provider is crucial. This approval ensures that the services provided are within the approved network, allowing for reimbursement. Choices A, B, and C are not directly related to the reimbursement process by private insurance companies. While greater access to any healthcare provider, allowance for early discharge, and concern for the quality of care are important considerations when designing a home health care program, they do not specifically impact the reimbursement process from private insurance companies.

Correct Answer: A

Rationale: The correct answer is A: Flour with iron. The Food Fortification Act of 2000 mandates the fortification of flour with iron to address iron deficiency in the population. Refined sugar is not typically fortified with iron, making choice B incorrect. While cooking oil fortification with vitamin A is common in some regions, it is not specified under the Food Fortification Act of 2000, rendering choice C incorrect. Similarly, rice fortification with vitamin A is not included in the mandatory fortification list according to the act, making choice D incorrect.

Correct Answer: A

Rationale: The primary goal of community health nursing is to promote health and prevent disease. Community health nurses focus on preventive care, health promotion, and education to improve the overall health of the community. Providing care to the sick (Choice B) is part of nursing but not the primary goal of community health nursing. While research (Choice C) and developing health policies (Choice D) may be components of community health nursing, they are not the primary goal, which is centered around promoting health and preventing disease.
