Question 1 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 is D because controlling the environment in the community is more challenging compared to an acute care setting. In the community, nurses face various environmental factors such as social determinants of health, limited resources, and diverse cultural backgrounds, making it harder to maintain a controlled and predictable environment for patient care. This can impact the delivery of care and outcomes. A: Limited access to information is not specific to community nursing and can also be a challenge in acute care settings. B: More paperwork and forms may be burdensome but do not inherently make community nursing more challenging than acute care. C: This choice is incomplete and does not provide a clear rationale for community nursing being more challenging.
Question 2 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 calculated by dividing the number of people who developed symptoms by the total number of people at risk. In this case, 63 out of 70 people developed symptoms, giving an attack rate of 90% (63/70 x 100%). This choice best describes the proportion of individuals who were affected. Explanation for incorrect choices: A: 63% is the proportion of people who developed symptoms out of the total number of people who ate the potato salad, not the total at-risk population. B: 70% is the proportion of people who ate the potato salad out of the total at-risk population, not the attack rate. D: 100% would imply that every single person who ate the potato salad developed symptoms, which is not the case based on the information provided.
Question 3 of 5
Which of the following actions would a nurse take to reduce the high incidence of coronary
Correct Answer: B
Rationale: The correct answer is B because it addresses prevention strategies at different levels: starting early with education in schools, reaching the general community with diet and exercise presentations, and targeting high-risk groups with specialized sessions. This comprehensive approach tackles the issue from multiple angles, promoting long-term behavior change and awareness. Choice A lacks specificity and does not provide a comprehensive plan to target different segments of the population. Choice C focuses mainly on online activities and screenings but lacks the community-wide educational aspect. Choice D includes some good elements like handouts and screenings but lacks the early intervention in schools and comprehensive community education approach present in choice B.
Question 4 of 5
A woman is sitting in a corner of the clinical waiting room, crying audibly. The nurse asks, “What’s wrong? Can I help?†The woman responds, “They just told me I have a positive mammogram and I need to see my doctor for follow-up tests. I know I’m going to die of cancer. How can I tell my family?†Which of the following information does the nurse need to know in order to help the woman cope with this finding?
Correct Answer: B
Rationale: The correct answer is B: The positive predictive value of mammography. In this scenario, the woman is distressed over a positive mammogram result, indicating a potential cancer diagnosis. Understanding the positive predictive value of mammography is crucial for the nurse to provide accurate information about the likelihood of the positive result truly indicating cancer. This information helps the nurse guide the woman on next steps and coping strategies. Choice A (The negative predictive value of mammography) is incorrect because the woman's concern is focused on a positive result indicating cancer, not on ruling out cancer. Choice C (The reliability of mammography) is incorrect as it pertains to the consistency of test results, which is not the immediate concern in this case. Choice D (The validity of mammography) is also incorrect as it refers to how accurately a test measures what it is intended to measure, but it does not directly address the woman's emotional distress and need for guidance on dealing with a positive result.
Question 5 of 5
A nurse reports that in comparison to all the children in a particular school, the children who
Correct Answer: D
Rationale: The correct answer is D: Encourage the parents to enroll their sons in Cub Scouts. The rationale for this is that the nurse should be promoting activities that have a positive impact on the children's development, such as Cub Scouts. Cub Scouts provide opportunities for social interaction, skill-building, leadership development, and community involvement. By encouraging the parents to enroll their sons in Cub Scouts, the nurse is supporting their holistic growth and well-being. Choice A is incorrect because it is unrelated to the nurse's role and does not address the children's well-being. Choice B is incorrect as it discourages a potentially beneficial activity without valid reasoning. Choice C is incorrect as it dismisses the potential benefits of Cub Scouts and does not consider the children's overall development.
