Community Health HESI Practice Exam

Correct Answer: A

Rationale: The most appropriate advice for an adolescent with acne is to eat a balanced diet for their age. A balanced diet that includes a variety of nutrients is essential for overall health, including skin health. While protein and Vitamin A are important for skin health, focusing solely on increasing these nutrients may not address the overall dietary needs. Similarly, solely decreasing fatty foods or avoiding caffeine may not be the most effective advice for managing acne. Therefore, the best advice is to promote a balanced diet tailored to the adolescent's age.

Correct Answer: B

Rationale: The correct answer is B. During the age of 2 to 3 years old, children tend to eat very small, nutritious meals throughout the day rather than having three large meals. This behavior is typical for this age group as their appetites fluctuate. Choices A, C, and D are incorrect because while children of this age may start to prefer feeding themselves and begin using a toothbrush with assistance, they typically do not speak in longer sentences at this stage.

Correct Answer: A

Rationale: The correct answer is A: Individual, interpersonal, organizational, community, and policy. The social ecological model examines how individual, interpersonal, organizational, community, and policy factors interact to influence health and well-being. Choice B is incorrect because it includes genetic and biological factors that are not part of the social ecological model. Choice C is incorrect as it does not include organizational and policy levels of influence. Choice D is incorrect as it includes wealth and politics, which are not typically considered in the social ecological model.

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: A

Rationale: The correct answer is Anthrax. Anthrax is a high-risk bioterrorism agent because it can be readily transmitted through multiple portals of entry such as inhalation, ingestion, or skin contact. This makes it a significant concern for use as a biological weapon. Smallpox, though highly contagious, is not known for multiple portals of entry like Anthrax. Botulism is a potent toxin but is not as easily transmissible through various routes as Anthrax. Tularemia, while a serious bacterial infection, does not have the same ease of transmission through multiple portals of entry as Anthrax.
