Community Health Nursing 2 Exam Questions and Answers Questions
Question 1 of 5
Which type of thinking is most reflective of looking at a macroscopic, big-picture population focus?
Correct Answer: C
Rationale: The correct answer is C: Holistic thinking. This type of thinking involves considering the entire system or population as a whole, focusing on interconnections and relationships between different components. It looks at the big-picture perspective rather than individual parts. Collaborative thinking (A) involves working together with others, not necessarily focusing on the population as a whole. Upstream thinking (B) involves addressing root causes of issues before they occur, but it doesn't necessarily focus on the big-picture population perspective. Downstream thinking (D) focuses on addressing consequences or effects after they have occurred, rather than the broader population perspective. Therefore, holistic thinking best aligns with the macroscopic, big-picture population focus.
Question 2 of 5
The incidence of type 2 diabetes among Indigenous peoples (First Nations, Inuit, and Métis) is three to five times higher than in the general population. When teaching a nutrition class to a group of mostly Indigenous students, the community health nurse (CHN) incorporates into the presentation such foods as bannock and other healthy dishes familiar to Indigenous students. What level of prevention does this culturally sensitive action represent?
Correct Answer: A
Rationale: The correct answer is A: Primary prevention. This action falls under primary prevention because it aims to prevent the occurrence of type 2 diabetes in Indigenous peoples by promoting healthy eating habits through culturally sensitive foods. By incorporating familiar and healthy dishes into the nutrition class, the community health nurse is focusing on preventing the development of the disease before it occurs. This approach addresses the underlying risk factors for diabetes, such as poor diet, in a proactive manner. Summary of other choices: B: Secondary prevention involves early detection and treatment of a disease to prevent complications. This action does not focus on early detection but rather on prevention. C: Tertiary prevention focuses on managing complications and improving quality of life for those already diagnosed with a disease. This action is aimed at preventing diabetes rather than managing its complications. D: This action is primarily focused on preventing the occurrence of type 2 diabetes before it develops, making it more aligned with primary prevention than secondary prevention.
Question 3 of 5
Risk management involves the selection and implementation of a strategy to reduce risks. It can take many forms—for example, the "four Rs for reducing environmental pollution,". The four Rs are:
Correct Answer: B
Rationale: The correct answer is B: Reduce, reuse, recycle, recover. 1. Reduce: Minimizing the generation of waste or pollution at the source is the most effective way to manage risks. 2. Reuse: Extending the life of products by using them multiple times reduces the need for new production, further reducing risks. 3. Recycle: Processing waste materials into new products helps reduce the environmental impact of resource extraction and manufacturing. 4. Recover: Extracting useful materials or energy from waste that cannot be reduced, reused, or recycled is a final step in managing risks. Summary: A: Incorrect. "Reproduce" and "redeliver" are not part of the typical risk management strategies related to environmental pollution. C: Incorrect. "Review" is not an action for reducing risks, and the order of actions is different from the standard reduce, reuse, recycle, recover approach. D: Incorrect. "Report" is not a direct action for reducing risks related to
Question 4 of 5
The CHN can enhance the sensitivity and specificity of a test by using its predictive value. Which one of the following best defines positive predictive value?
Correct Answer: D
Rationale: Positive predictive value (PPV) is the proportion of individuals with a positive test result who actually have the disease. This is crucial in determining the likelihood that a positive test accurately identifies a true positive case. By calculating PPV, we can assess the test's ability to predict the presence of the disease. In this context, the CHN (clinical history and physical examination) can help improve the accuracy of test results by enhancing the predictive value. Choice A is incorrect because it describes the negative predictive value, which is the proportion of individuals with a negative test result who are actually disease-free. Choice B is incorrect as it refers to the variability of the trait being measured, not predictive value. Choice C is incorrect as it discusses inconsistencies in the testing instrument, which are unrelated to predictive value.
Question 5 of 5
Which scenario exemplifies the community health nurse's (CHN's) practice of secondary prevention to reduce environmental health risks?
Correct Answer: A
Rationale: The correct answer is A because collecting blood specimens from preschool children to check for lead levels is an example of secondary prevention, which aims to detect and treat health problems early. This action helps identify children at risk for lead exposure and allows for early intervention to prevent further health issues. Choice B is incorrect because meeting with local government officials to request cleanup is more of a primary prevention strategy aimed at preventing exposure to environmental hazards in the first place. Choice C is incorrect as it involves tertiary prevention, focusing on treatment and management of existing health problems. Choice D is incorrect as it pertains to primary prevention by educating parents about lead exposure risks.
