Question 1 of 5
While conducting a literature review for an evidence-based project, the nurse recognizes that which type of study represents the lowest level of evidence?
Correct Answer: A
Rationale: The correct answer is A: Case reports. Case reports represent the lowest level of evidence because they are anecdotal, describing observations of individual cases without control groups or systematic data collection. They lack generalizability and are subject to bias. Cohort studies (
B), randomized control trials (
C), and cross-sectional studies (
D) are higher levels of evidence with more rigorous study designs and stronger ability to establish causation and relationships between variables. Cohort studies follow a group over time, RCTs involve random allocation of participants into groups, and cross-sectional studies provide a snapshot of a population at a specific point in time.
Question 2 of 5
A nurse has developed the following PICOT question: In adult men, is zinc supplementation as effective as vitamin C supplementation in reducing the length of respiratory viral infections over six months? The nurse identifies "zinc supplementation†as which part of the PICOT question?
Correct Answer: B
Rationale: The correct answer is B: Intervention. In a PICOT question, the 'Intervention' refers to the treatment or exposure being considered. In this case, the nurse is comparing zinc supplementation to vitamin C supplementation, making zinc supplementation the intervention being studied. The 'Population' would be adult men, 'Comparison' would be vitamin C supplementation, and 'Outcome' would be the reduction in the length of respiratory viral infections. The other choices are incorrect because they do not accurately represent the specific focus of the intervention being studied in the question.
Question 3 of 5
A public health nurse has developed a research question and searched the literature for supporting
Correct Answer: C
Rationale: The correct answer is C: Synthesizing the literature. In evidence-based decision-making, synthesizing the literature involves compiling research findings and identifying specific trends in the data. This step allows the nurse to analyze and interpret the information gathered from various sources to draw meaningful conclusions and make informed decisions. Defining the problem (choice
B) is the initial step of evidence-based decision-making. Appraising the literature (choice
D) comes after synthesizing, where the nurse evaluates the quality and relevance of the gathered evidence.
Choices E, F, and G are not applicable in this context.
Question 4 of 5
Which database would the public health nurse use when conducting research to locate regularly updated systematic reviews?
Correct Answer: A
Rationale: The correct answer is A: Cochrane Library. The Cochrane Library is renowned for regularly updated systematic reviews, providing high-quality evidence for healthcare decision-making. It follows strict methodology to ensure reliability. AHRQ (
B) focuses on healthcare quality improvement, not systematically updated reviews. While Medline (
C) and CINAHL (
D) are databases for primary research articles, they do not specifically focus on systematic reviews.
Therefore, Cochrane Library is the most appropriate database for the public health nurse's research needs.
Question 5 of 5
Which action will the public health nurse perform when conducting an ethical community study?
Correct Answer: D
Rationale: The correct answer is D because obtaining informed consent from each participant in the study is a fundamental ethical principle in research involving human subjects. This process ensures that participants are fully informed about the study, its risks, benefits, and their rights before agreeing to participate. This protects their autonomy and respects their right to make an informed decision about taking part in the study. Requiring each participant to provide informed consent also promotes transparency and trust between researchers and participants.
Choices A, B, and C are incorrect because they do not uphold the principle of obtaining informed consent from each participant, which is essential for ethical research conduct.
