Which action will the public health team take during the Exposure Assessment stage of the EPA's four- step risk assessment following a train derailment resulting in a toxic chemical spill?
- A. Identifying potential negative outcomes due to exposure to the toxic chemicals
- B. Identifying how the amount of exposure relates to the severity of negative health outcomes
- C. Quantifying the extent, frequency, and length of contact of the community with the toxic chemicals
- D. Determining how the toxic chemicals are absorbed, metabolized, and eliminated from the body
Correct Answer: C
Rationale: During the Exposure Assessment stage, the public health team will quantify the extent, frequency, and length of contact of the community with the toxic chemicals. This is crucial for determining the level of risk posed by the exposure. Identifying potential negative outcomes (Choice A) is important but falls under the Hazard Identification stage. Understanding the relationship between exposure amount and health outcomes (Choice B) is part of the Dose-Response Assessment stage. Determining how chemicals interact with the body (Choice D) is covered in the Toxicokinetics stage. Therefore, choice C is correct as it directly addresses the primary focus of the Exposure Assessment stage.

A nurse successfully persuades an obese client to perform a weekly weigh-in at homeusing a digital scale and record the weight in a log. This strategy is an example of:
- A. Telehealth
- B. Health information technology
- C. Personal responsibility for health
- D. Evidenc
Correct Answer: C
Rationale: The correct answer is C, "Personal responsibility for health." This is because by persuading the client to monitor and record their weight at home, the nurse is empowering the client to take ownership of their health and actively participate in managing their weight. This strategy encourages the client to be accountable for their health outcomes and promotes self-care. Option A, "Telehealth," is incorrect because it refers to the delivery of healthcare services through technology, not necessarily personal responsibility. Option B, "Health information technology," is also incorrect as it pertains to the use of technology to manage health information, not about individual responsibility. Option D is cut off, but if it were "Evidence-based practice," it would be incorrect as it does not directly relate to the client's responsibility for their health.
Which environmental health activity would the nurse perform while engaged in the core public health function of assurance?
- A. Educating the community about the need to boil contaminated drinking water
- B. Collecting data about health issues related to contaminated drinking water
- C. Developing polices to regulate the discharge of pollutants into the waterways
- D. Assessing measures to reduce exposure to contaminated water
Correct Answer: D
Rationale: The correct answer is D: Assessing measures to reduce exposure to contaminated water. This activity falls under the assurance function as it involves ensuring that appropriate measures are in place to protect the community from health risks associated with contaminated water. By assessing these measures, the nurse is actively working to reduce the community's exposure to harmful contaminants, thereby fulfilling the role of assuring the public's health.
A: Educating the community about the need to boil contaminated drinking water falls under the core function of education rather than assurance.
B: Collecting data about health issues related to contaminated drinking water is a part of the assessment function, not assurance.
C: Developing policies to regulate the discharge of pollutants into the waterways is more aligned with the policy development function rather than assurance.
In summary, the correct answer focuses on actively evaluating and implementing measures to reduce exposure to contaminated water, which directly contributes to the assurance function of environmental health.
A nurse is caring for a client following application of a cast. Which of the following actions should the nurse take first?
- A. Palpate the distal pulse to the cast
- B. Engage employers to have wellness centers at each industrial site
- C. Ensure timely and effective medical intervention and treatment for community members
- D. Giving some of their own surplus clothes to those who can use them
Correct Answer: A
Rationale: The correct answer is A: Palpate the distal pulse to the cast. This is the first action the nurse should take as it assesses the circulation to the extremity. Checking the distal pulse ensures that there is no compromise to blood flow post-casting, which is crucial in preventing complications like compartment syndrome. Engaging employers (B), ensuring community medical interventions (C), and donating clothes (D) are unrelated and not urgent in this scenario. It is important to prioritize patient safety and monitor for any potential complications following cast application.
Which information is the nurse assessing when appraising the applicability of a research article?
- A. The intended audience of the article
- B. The degree to which the results relate to a specific population
- C. The accuracy or credibility of the research
- D. The purpose of the research
Correct Answer: B
Rationale: The correct answer is B: The degree to which the results relate to a specific population. This is crucial in determining the relevance and applicability of the research findings to the target population. Assessing the generalizability of the results is essential for making informed decisions in practice.
Incorrect Choices:
A: The intended audience of the article - While important, it does not directly impact the applicability of the research findings to a specific population.
C: The accuracy or credibility of the research - While important for validity, it does not address the specific relevance to a population.
D: The purpose of the research - While understanding the purpose is important, it doesn't directly assess the applicability to a specific population.
A nurse is planning a community health program about Parkinson's disease. Which of the following interventions should the nurse include as a tertiary prevention strategy?
- A. Provide daily exercise classes to improve ambulation for clients who have Parkinson's disease.
- B. Provide screenings for community members to identify early manifestations of Parkinson's disease.
- C. Educate clients about common techniques used to diagnose Parkinson's disease.
- D. Educate clients who are at risk for Parkinson's disease about maintaining a low-cholesterol diet.
Correct Answer: A
Rationale: The correct answer is A: Provide daily exercise classes to improve ambulation for clients who have Parkinson's disease. Tertiary prevention aims to prevent complications and further deterioration in individuals already diagnosed with a disease. In Parkinson's disease, exercise is crucial to maintain mobility and function. Regular exercise helps improve balance, strength, and coordination, which can slow down the progression of the disease and enhance quality of life. Providing daily exercise classes specifically tailored to individuals with Parkinson's disease aligns with tertiary prevention goals by promoting physical activity and independence.
Choice B is incorrect as it focuses on early identification rather than intervention for those already diagnosed. Choice C is incorrect as educating about diagnostic techniques is more aligned with secondary prevention. Choice D is incorrect as maintaining a low-cholesterol diet is not a specific tertiary prevention strategy for Parkinson's disease.
