Which of the following types of study should the nurse researcher choose if the goal is to identify the
- A. Cross-sectional study
- B. Ecologic study
- C. Clinical trial
- D. Retrospective analysis
Correct Answer: A
Rationale: The correct answer is A: Cross-sectional study. This type of study is best suited for identifying the current prevalence of a condition or characteristic within a population at a specific point in time. It provides a snapshot of the population, allowing for quick and efficient data collection. Cross-sectional studies are ideal for determining associations between variables but cannot establish causality. The other choices are incorrect because: B: Ecologic study examines population-level data rather than individual-level data, making it less suitable for identifying specific characteristics within a population. C: Clinical trial focuses on testing interventions and treatments rather than identifying characteristics. D: Retrospective analysis looks back at past data and may not provide a current snapshot of the population.

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?
- A. The negative predictive value of mammography
- B. The positive predictive value of mammography
- C. The reliability of mammography
- D. The validity of mammography
Correct Answer: A
Rationale: The correct answer is A: The negative predictive value of mammography. The nurse needs this information to help the woman cope because it indicates the probability that a negative mammogram truly indicates the absence of breast cancer. Knowing this value can provide reassurance to the woman that a positive mammogram doesn't definitively mean she has cancer. The other choices are incorrect because: B (Positive predictive value) focuses on the likelihood of cancer if the test is positive, which may increase the woman's anxiety. C (Reliability) refers to the consistency of results, but it doesn't directly address the woman's concerns about her health. D (Validity) assesses how well a test measures what it is supposed to measure, but it doesn't offer immediate reassurance to the woman in this emotional moment.
The Refugee Act of 1980 had what effect on refugees who were immigrating into the United States?
- A. Allowed specific provisions for refugees from Southern and Eastern Europ
- C. C M U S N T O
- D. Provided a uniform procedure for refugees to be admitted into the United States.
Correct Answer: D
Rationale: The Refugee Act of 1980 established a uniform procedure for admitting refugees into the US. This means that it created a standardized process for evaluating refugee applications and determining eligibility, ensuring fairness and consistency. This is crucial in managing the influx of refugees and providing them with necessary support. The other choices are incorrect because A is not accurate as the Act applied to refugees from all regions, not just Southern and Eastern Europe. Choices B, C, E, F, and G are not valid options and do not relate to the impact of the Refugee Act of 1980 on refugees immigrating to the US.
Persons in an auditorium may have been exposed to a disease. If they are infected, it is crucial that they receive immediate treatment and not take the disease home to their families. Which of the following characteristics would be most important to consider when selecting the screening test to be used?
- A. The negative predictive value
- B. The positive predictive value
- C. The sensitivity of the test
- D. The specificity of the test
Correct Answer: C
Rationale: The correct answer is C: The sensitivity of the test. Sensitivity measures the ability of a test to correctly identify individuals who have the disease (true positives). In this scenario, selecting a screening test with high sensitivity is crucial to ensure that infected individuals are accurately identified and receive immediate treatment to prevent spreading the disease to their families.
A: The negative predictive value - This measures the probability that individuals with a negative test result truly do not have the disease and is not as important in this case where immediate treatment is vital.
B: The positive predictive value - This measures the probability that individuals with a positive test result truly have the disease and is not as critical as sensitivity in this context.
D: The specificity of the test - This measures the ability of a test to correctly identify individuals who do not have the disease (true negatives) and is not the most important consideration when the goal is to identify infected individuals for immediate treatment.
A nurse is a member of an interdisciplinary committee whose goal is to develop a culturally and linguistically competent organization. Which action by the committee would help to meet this goal?
- A. Develop an organizational mission statement for cultural competence
- B. Encourage each department to develop a cultural competency plan
- C. Encourage employees to find ways to develop their cultural competence
- D. Hire individuals with the most work experience
Correct Answer: A
Rationale: The correct answer is A, developing an organizational mission statement for cultural competence. This is crucial as it sets the tone and direction for the entire organization's commitment to cultural and linguistic competence. It provides a clear framework and guiding principles for all activities and decisions related to this goal. Choices B and C are not sufficient on their own as they lack a cohesive and overarching strategy. Choice D is irrelevant to the goal of cultural competence. It is important to have a clear, shared vision through the mission statement to ensure alignment and accountability across all departments and individuals.
Two nurses plan to walk under a huge downtown bridge where various homeless persons live. Why
- A. Introduction of a heart-healthy curriculum beginning in the first grade, presentations on diet and
- B. Provision of online activities related to prevention of cardiac disease, smoking reduction programs,
- C. Distribution of handouts, including age-appropriate games, self-assessments, and education on heart-
- D. Enrollment of clients with CAD into cardiac rehabilitation programs, routine evaluation of
Correct Answer: A
Rationale: The correct answer is A because introducing a heart-healthy curriculum in first grade lays a strong foundation for promoting heart health early on. By educating children about diet and exercise at a young age, it instills healthy habits that can prevent cardiac disease in the future. Choice B focuses on online activities and smoking reduction programs, which may not have as significant an impact as starting heart-healthy education at a young age. Choice C mentions handouts and games, which may not be as effective as a structured curriculum. Choice D focuses on enrolling clients with CAD into rehabilitation programs, which is more reactive than proactive in preventing cardiac diseases.
