Question 2 of 5
Which of the following statements describes how nursing in the community is more challenging than nursing in an acute care setting?
Correct Answer: D
Rationale: The correct answer, D, is more challenging to control the environment in the community, as the community setting is dynamic and unpredictable. Nurses in the community face various environmental factors such as social determinants of health, safety concerns, and limited resources. This makes it difficult to ensure a controlled and safe environment for providing care. A: Limited access to information is not necessarily true, as nurses can utilize various resources and technology for information in the community setting. B: More paperwork is a common challenge in both settings, but it does not specifically make community nursing more challenging. C: This is an incomplete statement and does not provide a clear comparison between community and acute care settings.
Question 3 of 5
The nursing staff has attempted to screen the entire African American population in the community for diabetes. Which of the following would provide immediate verification of the success of the nursing staff’s efforts?
Correct Answer: D
Rationale: The correct answer is D because a decrease in the prevalence of diabetes in the community would indicate that the nursing staff's efforts to screen the African American population for diabetes have been successful. This is because a decrease in prevalence shows that fewer people in the community have diabetes, suggesting that early detection and intervention have led to a lower overall burden of the disease. A, B, and C are incorrect because: A: An epidemic of diabetes would not verify the success of the nursing staff's efforts, as it indicates a widespread outbreak rather than successful screening efforts. B: This option is incomplete and does not provide a logical outcome related to the screening efforts. C: An increase in the incidence of diabetes would suggest a worsening situation, not the success of the screening efforts.
Question 4 of 5
A public health nurse found that out of the 70 people who ate the potato salad at a school picnic, 63 developed symptoms of food poisoning. Which of the following best describes the attack rate?
Correct Answer: C
Rationale: The attack rate is the proportion of people exposed to a specific factor who develop a particular health outcome. In this case, the attack rate is calculated by dividing the number of people who developed symptoms (63) by the total number of people who ate the potato salad (70) and multiplying by 100. This gives us an attack rate of 90% (63/70 x 100 = 90%). This means that 90% of the people who ate the potato salad developed food poisoning symptoms. Summary of incorrect choices: A: 63% - This is the proportion of people who developed symptoms out of the total number of people who ate the potato salad, not the attack rate. B: 70% - This is the total number of people who ate the potato salad, not the attack rate. D: 100% - This would imply that everyone who ate the potato salad developed symptoms, which is not the case based on the given information.
Question 5 of 5
Which of the following actions would a nurse take to reduce the high incidence of coronary
Correct Answer: B
Rationale: Step 1: Introduction of heart-healthy curriculum in first grade instills early awareness and habits. Step 2: Presentations on diet and exercise educate the community on preventive measures. Step 3: Special education sessions for high-risk populations target those most vulnerable. Summary: Choice A lacks specificity and targeted approach. Choice C focuses mainly on online activities, lacking community engagement. Choice D includes some good elements but lacks a comprehensive and early intervention approach like Choice B.
