Community Health HESI Practice Exam

Correct Answer: B

Rationale: Epidemiology is the study of the distribution and determinants of health-related states in populations. Choice A is incorrect because epidemiology focuses on more than just causes but also on distribution and determinants. Choice C is incorrect as it specifically relates to public health and not just treatment and prevention. Choice D is incorrect as epidemiology is broader than just focusing on the healthcare system and its effectiveness.

Correct Answer: D

Rationale: The correct answer is 'Parasitism as a health threat.' This choice accurately describes the ongoing issue of parasitic infections in the community, highlighting the seriousness and urgency of the problem. Choice A ('Parasitism as a foreseeable crisis') is incorrect as it does not emphasize the immediate danger posed by parasitic infections. Choice B ('Malnutrition as a health deficit') is not the most relevant diagnosis considering the context provided. Choice C ('Parasitism as a health deficit') is also incorrect as it fails to capture the level of risk and urgency associated with parasitic infections in this scenario.

Correct Answer: C

Rationale: In this scenario, requesting mayors to create a task force is the most effective strategy to improve environmental health conditions in the community. Engaging with local government officials ensures the allocation of resources, coordination of efforts, and the implementation of sustainable solutions. While meeting with youth officials, parents' group leaders, religious and educational leaders are important, involving mayors in creating a task force will lead to broader community involvement and support. Informing local announcers about the project, although helpful for awareness, is not as impactful as engaging with local authorities for tangible change.

Correct Answer: C

Rationale: The correct answer is C, Semi-Fowler's. This position helps to reduce intracranial pressure by promoting venous drainage from the head while maintaining adequate oxygenation. Option A, Trendelenburg position, is incorrect as it involves placing the patient with the head lower than the body, which can increase intracranial pressure. Option B, Prone position, is also incorrect as it involves lying on the stomach, which can further elevate intracranial pressure. Option D, Side-lying with head flat, does not provide the same benefits as the Semi-Fowler's position in terms of promoting venous drainage and maintaining oxygenation in a client with increased intracranial pressure.

Correct Answer: B

Rationale: The correct answer is B, Incidence. Incidence refers to the number of new cases of a disease in a specific population during a certain time period. Prevalence (choice A) refers to the total number of cases of a disease in a population at a specific point in time. Mortality rate (choice C) is the measure of the number of deaths in a particular population due to a specific cause. Morbidity rate (choice D) is a broader term that encompasses the incidence and prevalence of a disease in a population.
