Community Health Nursing 2 Exam Questions and Answers Questions
Question 1 of 5
Which of the following terms means telling the truth?
Correct Answer: D
Rationale: The correct answer is D: Veracity. Veracity refers to telling the truth, which is an essential ethical principle in healthcare. Nonmaleficence means to do no harm, Principlism is a moral framework based on principles, and Utilitarianism focuses on maximizing overall utility. Veracity is the only term directly related to truth-telling in this context.
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
Which model best explains the reasons why homeless individuals are at increased risk of disease as a result of multiple agent, host, and environmental factors?
Correct Answer: A
Rationale: The correct answer is A: The web of causality. This model best explains the complex interactions among agent, host, and environmental factors contributing to the increased disease risk in homeless individuals. It emphasizes the interconnectedness and multifactorial nature of health outcomes. Rationale: 1. The web of causality considers the interplay of various factors, such as social determinants of health, living conditions, access to healthcare, and individual behaviors, which collectively influence health outcomes in homeless populations. 2. This model recognizes the dynamic and non-linear relationships between different factors, illustrating how a combination of biological, social, and environmental elements can contribute to disease vulnerability. 3. In contrast, the epidemiological triangle primarily focuses on the relationship between the agent, host, and environment in causing specific diseases, overlooking the broader systemic factors affecting homeless individuals' health. 4. The levels of prevention framework and the Health Promotion Model are more focused on intervention strategies and individual behavior change, rather than capturing the complexity and interconnected
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 objective is most appropriate for developing a community health nursing process?
Correct Answer: C
Rationale: Rationale for Choice C: The most appropriate objective for community health nursing is to ensure a high immunization rate among children to prevent the spread of diseases. Immunization is a crucial public health intervention that protects individuals and the community. Achieving a high immunization rate, such as 95%, by age 1 is a specific, measurable, achievable, relevant, and time-bound (SMART) goal that aligns with the core purpose of community health nursing. Rationale for why other choices are incorrect: A: This objective is not appropriate for community health nursing as it focuses on a specific medical intervention rather than a population-level public health goal. B: While nutrition counseling is important, this objective is not as critical for community health nursing as ensuring high immunization rates among children. D: This objective is vague and does not directly address a specific health issue or population group, making it less relevant for community health nursing.
