HESI LPN
Community Health HESI Practice Exam
1. The term 'epidemiology' is best defined as the study of:
- A. The causes of disease
- B. The distribution and determinants of health-related states in populations
- C. The treatment and prevention of disease
- D. The healthcare system and its effectiveness
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.
2. Which of the following is a voluntary organization?
- A. NIH
- B. FDA
- C. CDC
- D. ADA
Correct answer: D
Rationale: The American Diabetes Association (ADA) is a voluntary organization that relies on voluntary contributions and membership fees. NIH (National Institutes of Health), FDA (Food and Drug Administration), and CDC (Centers for Disease Control and Prevention) are governmental agencies and not voluntary organizations. Therefore, the correct answer is D.
3. In the implementation of the national family planning program, the government assumes the role of a:
- A. decision-maker in the practice of family planning methods
- B. regulator
- C. facilitator
- D. dictator
Correct answer: C
Rationale: The correct answer is C: 'facilitator.' In the implementation of a national family planning program, the government plays a role as a facilitator, meaning it helps to support and enable the access to family planning services and information. The government's role is to ensure that services are available, accessible, and of good quality, rather than making decisions for individuals or regulating them. Choices A, B, and D are incorrect because the government's role is not to make decisions on behalf of individuals (decision-maker), strictly regulate family planning practices (regulator), or impose decisions without considering individual choices (dictator).
4. A health program that aims to reduce the incidence of chronic diseases through lifestyle modifications is an example of:
- A. Primary prevention
- B. Secondary prevention
- C. Tertiary prevention
- D. Quaternary prevention
Correct answer: A
Rationale: The correct answer is A: Primary prevention. Primary prevention focuses on preventing the development of diseases or injuries before they occur by promoting healthy behaviors and lifestyles. In this scenario, the health program targeting lifestyle modifications to reduce chronic diseases aligns with primary prevention efforts. Choice B, secondary prevention, involves early detection and treatment to prevent the progression of disease. Choice C, tertiary prevention, focuses on managing and treating existing diseases to prevent complications. Choice D, quaternary prevention, relates to actions taken to mitigate or avoid the consequences of unnecessary or excessive interventions in healthcare.
5. The healthcare provider is evaluating the health status of a 16-year-old client with a history of Type 1 diabetes. Which laboratory test would provide the most accurate information about long-term blood glucose control?
- A. Blood glucose level
- B. Glycosylated hemoglobin
- C. Urine ketones
- D. Serum insulin level
Correct answer: B
Rationale: The correct answer is B: Glycosylated hemoglobin (HbA1c). Glycosylated hemoglobin provides valuable information about blood glucose control over the past 2-3 months. This test measures the average blood sugar levels during this period, offering a more comprehensive view of long-term glycemic control. Choice A, blood glucose level, reflects the blood sugar concentration at the time of testing and may fluctuate throughout the day. Choice C, urine ketones, indicates the presence of ketones and is more relevant for assessing acute complications like diabetic ketoacidosis. Choice D, serum insulin level, evaluates insulin production and is not a direct indicator of long-term blood glucose control in diabetes management.
