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: 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.

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: health education. Health education is crucial for individuals dealing with chronic illnesses as it helps them learn how to manage their conditions effectively. Communicable disease control (choice A) focuses on preventing the spread of infectious diseases, which is not directly related to managing chronic conditions. Child survival (choice C) pertains to initiatives aimed at reducing child mortality rates, which is not directly related to addressing chronic illnesses. Environmental education (choice D) involves raising awareness about environmental issues, which is also not directly related to helping individuals live with chronic illnesses.

Correct Answer: D

Rationale: The correct answer is D: 12-24 hours. Withdrawal symptoms typically begin within 12-24 hours after the last drink. This period is when the client is at the highest risk for experiencing withdrawal symptoms. Choices A, B, and C are incorrect because they do not align with the typical timeline for alcohol withdrawal symptoms to manifest. Symptoms usually peak within the first 24 to 48 hours after the last drink, making the 12-24 hour window critical for monitoring and managing any potential withdrawal complications.
