Question 1

John is looking at the findings and notices that the study cites the incidence and prevalence of infection in an Emergency Department. The nurse demonstrates his knowledge of this terminology when he states to his peer:

Accepted Answer

Incidence refers to the proportion of new cases of a disease or infection in a specific population over a certain period of time. Prevalence refers to the proportion of individuals in a population who have a particular disease or infection at a given point in time. Therefore, option A correctly describes the difference between incidence and prevalence. Option B is incorrect because it switches the definitions of incidence and prevalence. Option C is incorrect because the incidence and prevalence alone do not indicate whether the infection is worsening or not. Option D is incorrect because incidence and prevalence have distinct definitions and are not interchangeable.

Question 2

John, an Emergency Room nurse, is interested in implementing evidence-based practice into his workplace. John knows there is a process that he must follow. The nurse demonstrates his knowledge of the evidence-based practice process when he states to his manager:

Accepted Answer

In order to implement evidence-based practice, John must first define his clinical question and then search the literature for evidence on how to best address that question. By defining his question first, John can avoid wasting time and resources by searching for irrelevant information. Once he has identified relevant literature, John can evaluate and analyze it to determine the best course of action.

Question 3

From the list below, which two terms does the term evidence-based practice encompass?

Accepted Answer

Evidence-based practice encompasses both evidence-based medicine and evidence-based care, meaning that it involves the implementation of research-based evidence into clinical decision making and care delivery. The other options either do not fully capture the breadth of evidence-based practice or are not direct components of it.

Question 4

When researching a focused clinical question, what type of source would provide an appraisal of comprehensive current evidence?

Accepted Answer

A systematic review is the best choice for providing an appraisal of comprehensive current evidence. It is a type of study that uses a rigorous process to identify, evaluate, and synthesize all available evidence on a specific clinical question. It provides a summary of the best available evidence, taking into account the strengths and limitations of individual studies.

Accepted Answer

The answer of Which type of evidence is used by...

Question 10

When searching the literature, John finds that it is important to have an understanding of research terminology. The first study involved six (6) participants who participated in one-on-one interviews. The data collected from the interviews is very important to John because it describes in detail the feelings of the participants, which gives John a better understanding of the issue he is researching. The nurse demonstrates his knowledge of descriptive research and research terminology when he states to his manager:

Accepted Answer

The use of one-on-one interviews and the focus on describing the feelings of participants suggest that this study is qualitative in nature. Therefore, choice A is the best option as it correctly identifies the research paradigm being used. Choices B and C are incorrect as they suggest a quantitative approach and a small control group, respectively, which do not match the description of the study. Choice D is not a specific enough response and does not demonstrate knowledge of research terminology.
