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, 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 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 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 3 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.
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. The nurse needs to know the probability that a positive mammogram result truly indicates the presence of cancer in this specific woman. Understanding the positive predictive value will help the nurse provide accurate information and emotional support to the woman. Choice A (negative predictive value) is not relevant as the woman has a positive result. Choice C (reliability) and D (validity) are important but do not address the specific concern of the woman about the likelihood of having cancer based on a positive result.

Correct Answer: D
Rationale: The correct answer is D: Encourage the parents to enroll their sons in Cub Scouts. The nurse should recommend this because Cub Scouts can provide a positive and enriching experience for the boys in terms of social skills, character development, and physical activities. It is relevant to the children's overall well-being and can contribute to their growth and development. Option A is incorrect as it does not address the benefits of joining Cub Scouts. Option B is incorrect as it discourages enrollment without considering the potential positive impact. Option C is incorrect as it dismisses the relevance of Cub Scouts without considering its potential benefits for the children.
