Community Health HESI Practice Exam
1. Which bioterrorism agent poses a high risk for use as a potential biological weapon due to its ability to be readily transmitted through several portals of entry?
- A. Anthrax.
- B. Smallpox.
- C. Botulism.
- D. Tularemia.
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.
2. When a nurse teaches a community about the importance of regular health screenings, this activity falls under which level of prevention?
- A. Primary prevention
- B. Secondary prevention
- C. Tertiary prevention
- D. Quaternary prevention
Correct answer: B
Rationale: The correct answer is B: Secondary prevention. Secondary prevention aims to detect and treat disease early to prevent complications. Teaching about the importance of regular health screenings helps in early detection and intervention, which aligns with the goals of secondary prevention. Choice A, Primary prevention, involves actions to prevent the onset of a health condition. Choice C, Tertiary prevention, focuses on managing and treating existing conditions to prevent further complications. Choice D, Quaternary prevention, relates to actions taken to mitigate or avoid unnecessary interventions, over-medicalization, and the consequences of unnecessary treatment.
3. What is the measure of the number of new cases of a disease in a specific population during a certain time period called?
- A. Prevalence
- B. Incidence
- C. Mortality rate
- D. Morbidity rate
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.
4. From January 1 to 15, 1996, there were 8 cases of Tetanus neonatorum in San Lazaro Hospital. There were two deaths. What is the case fatality ratio of this disease?
- A. 20%
- B. 30%
- C. 28%
- D. 25%
Correct answer: D
Rationale: The case fatality ratio is calculated as (deaths/cases) * 100. In this case, there were 2 deaths out of 8 cases. Therefore, the calculation is (2/8) * 100 = 25%. Choices A, B, and C are incorrect as they do not match the correct calculation.
5. Which of the following is a contribution of community health nurses to the community's health?
- A. providing health education to vulnerable populations
- B. coordinating access to integrated care for the population
- C. developing comprehensive health care systems in various settings
- D. all of the above
Correct answer: D
Rationale: Community health nurses play a vital role in promoting community health by providing health education to vulnerable populations (Choice A), coordinating access to integrated care for the population (Choice B), and developing comprehensive health care systems in various settings (Choice C). These contributions work together to enhance the overall health and well-being of the community, making choice D, 'all of the above,' the correct answer. Choices A, B, and C are all essential aspects of the multifaceted approach that community health nurses take to improve the health outcomes of the community.
