When a concerned citizen asks the community health nurse (CHN) about environmental health, what definition of environmental health does the CHN provide?
- A. Environmental health is the causative factors invading a susceptible host through an environment favourable to producing disease, such as a biological or chemical agent.
- B. Environmental health is the systematic and ongoing observation and collection of data concerning disease occurrence to describe phenomena and detect changes in frequency or distribution.
- C. Environmental health is the study of the effect of physical, chemical, and biological factors in the external environment on human health.
- D. Environmental health is the achievement of health and wellness and the prevention of illness and injury from exposure to physical or psychosocial environmental hazards.
Correct Answer: C
Rationale: The correct answer is C because it directly defines environmental health as the study of the impact of external factors on human health. Physical, chemical, and biological elements in the environment can influence health outcomes. Choice A focuses on disease causation, not the broader scope of environmental health. Choice B discusses disease surveillance, not the study of environmental factors. Choice D emphasizes achieving health goals, not the study of environmental factors. Therefore, choice C is the most accurate definition of environmental health.

A registered nurse (RN), has just been employed as a community health nurse (CHN). Which question would be most relevant to practice as the nurse begins her position?
- A. "Which community groups are at greatest risk for problems?"
- B. "Which patients should I see first as I begin my day?"
- C. "With which physicians will I be collaborating most closely?"
- D. "Who is the nursing assistant to whom I can refer patients?"
Correct Answer: A
Rationale: The correct answer is A: "Which community groups are at greatest risk for problems?" This question is most relevant for a community health nurse (CHN) as it aligns with the primary focus of community health nursing, which is to identify and address health needs within the community. By understanding which community groups are at greatest risk, the nurse can prioritize interventions and allocate resources effectively.
Rationale:
1. A focuses on population health, which is a core component of community health nursing.
2. Identifying high-risk groups allows for targeted interventions and preventive measures.
3. Understanding community needs is essential for developing culturally appropriate and effective health programs.
Summary:
B, C, and D are incorrect because they focus on individual patients, specific collaborations, and referral processes rather than the broader community health perspective that is crucial for a community health nurse.
A community health nurse (CHN) states, "The best way to treat clients from other countries is to care for them the same way we would want to be cared for ourselves. After all, we are all human beings with the same expectations and needs." What response does this statement exemplify?
- A. Cultural awareness
- B. Cultural blindness
- C. Cultural knowledge
- D. Cultural preservation
Correct Answer: B
Rationale: The correct answer is B: Cultural blindness. This statement exemplifies cultural blindness because it ignores the importance of cultural differences and assumes that everyone has the same expectations and needs. Cultural awareness (A) involves recognizing and respecting cultural differences. Cultural knowledge (C) involves understanding different cultures. Cultural preservation (D) involves protecting and maintaining cultural traditions. In this case, the statement demonstrates a lack of awareness and sensitivity to cultural diversity, making it an example of cultural blindness.
What is the biggest challenge for community health nurses (CHNs) who are familiar with evidence-informed practice and want to implement it in their care of clients?
- A. Interpreting vast amounts of evidence and integrating it into practice
- B. Advocating for change and convincing others that it is beneficial
- C. Distinguishing evidence-informed practice from practice based on old standards
- D. Showing clients that evidence-informed practice will improve their health outcomes
Correct Answer: A
Rationale: The correct answer is A because interpreting vast amounts of evidence and integrating it into practice is a significant challenge for community health nurses (CHNs) familiar with evidence-informed practice. CHNs need to sift through numerous research studies, guidelines, and data to make informed decisions about client care. By effectively integrating evidence into practice, CHNs can ensure that their interventions are based on the best available evidence, leading to improved client outcomes.
Choice B is incorrect because advocating for change is not the primary challenge related to implementing evidence-informed practice. Choice C is incorrect because distinguishing evidence-informed practice from outdated standards is important but not the biggest challenge. Choice D is incorrect because showing clients the benefits of evidence-informed practice is essential but not the main challenge faced by CHNs in implementing it.
Which public health service best represents primary prevention?
- A. Administering the influenza vaccine to a group of seniors
- B. Initiating an infant car seat safety screening program for parents in low-income housing
- C. Starting a rehabilitation clinic for middle-aged adults who reside in low-income housing
- D. Setting up a blood pressure screening clinic at the local mall
Correct Answer: B
Rationale: The correct answer is B because initiating an infant car seat safety screening program for parents in low-income housing best represents primary prevention. Primary prevention aims to prevent the occurrence of a disease or injury before it occurs. In this case, educating parents on proper car seat safety practices helps prevent injuries to infants in the first place. Administering the influenza vaccine (A) is an example of secondary prevention as it aims to detect and treat existing conditions. Starting a rehabilitation clinic (C) and setting up a blood pressure screening clinic (D) are also examples of secondary prevention as they focus on managing existing health conditions rather than preventing them.
Which of the following would be considered part of a transformational leadership style?
- A. A group leader uses rewards to engage others.
- B. A group leader uses personal charisma to motivate followers.
- C. A group leader focuses on day-to-day tasks.
- D. Minimal or no direction is provided by the group leader.
Correct Answer: B
Rationale: The correct answer is B because transformational leadership involves inspiring and motivating followers through personal charisma and vision. Charismatic leaders are able to influence and inspire others to achieve common goals. Choice A focuses on transactional leadership, which involves rewards for performance. Choices C and D are characteristics of laissez-faire leadership, where the leader is hands-off or focused solely on tasks, not inspiring transformation.
