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. The hospital is planning to downsize and eliminate a number of staff positions as a cost-saving measure. To assist staff in this change process, the nurse manager is preparing for the "unfreezing" phase of change. With this approach and phase the nurse manager should
- A. Discuss with the staff how to deal with any defensive behavior
- B. Explain to the unit staff why change is necessary
- C. Assist the staff during the acceptance of the new changes
- D. Clarify what the changes mean to the community and hospital
Correct answer: B
Rationale: The "unfreezing" phase involves preparing staff for change by explaining the necessity and benefits of the change, helping them to understand and accept it.
3. Which of the following activities is an example of tertiary prevention?
- A. Health education
- B. Regular exercise
- C. Screening tests
- D. Physical therapy
Correct answer: D
Rationale: The correct answer is D, physical therapy. Tertiary prevention focuses on rehabilitation and treatment to prevent complications from a disease or injury. Physical therapy falls under this category as it helps individuals recover and improve functionality after an illness or injury. Choices A, B, and C are not examples of tertiary prevention. Health education (choice A) is more aligned with primary prevention by promoting healthy behaviors to prevent disease onset. Regular exercise (choice B) can be categorized under both primary and secondary prevention as it aims to prevent disease development and detect conditions early. Screening tests (choice C) are part of secondary prevention as they aim to detect diseases at an early stage for prompt treatment.
4. Care provided by specialists in health facilities such as medical centers, regional, and provincial hospitals falls under which level of care?
- A. Secondary level care
- B. Primary care
- C. Tertiary care
- D. Intermediate care
Correct answer: C
Rationale: Tertiary care is the correct answer because it involves specialized care provided by medical centers and regional or provincial hospitals. Primary care (Choice B) refers to basic healthcare services usually delivered by general practitioners, nurses, and other healthcare professionals. Secondary care (Choice A) involves specialized services provided by medical specialists and other health professionals who generally do not have first contact with patients. Intermediate care (Choice D) is not a recognized level of care in the typical healthcare system hierarchy; it may cause confusion as it's not a standard term used to describe levels of care.
5. A child and his family were exposed to Mycobacterium tuberculosis about 2 months ago. To confirm the presence or absence of an infection, it is most important for all family members to have a
- A. Chest x-ray
- B. Blood culture
- C. Sputum culture
- D. PPD intradermal test
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.
