ANSWERS

Which statement best describes evidence-based practice (EBP)?
|\ |\ |\ |\ |\ |\




a. A combination of best research evidence, clinical expertise,
|\ |\ |\ |\ |\ |\ |\ |\ |\


and the needs and values of patients
|\ |\ |\ |\ |\ |\




b. A determination of the factors necessary to control patient
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


responses to care and delivery of care |\ |\ |\ |\ |\ |\




c. The development of population care guidelines applicable to all
|\ |\ |\ |\ |\ |\ |\ |\ |\


patients
|\ |\




d. The utilization of quantitative and qualitative studies to
|\ |\ |\ |\ |\ |\ |\ |\ |\


enhance patient outcomes - CORRECT ANSWERS ✔✔Answer: A
|\ |\ |\ |\ |\ |\ |\ |\


combination of best research evidence, clinical expertise, and the
|\ |\ |\ |\ |\ |\ |\ |\


needs and values of patients
|\ |\ |\ |\ |\




Rationale: Evidence-based practice evolves from the integration
|\ |\ |\ |\ |\ |\ |\


of the best research evidence with clinical expertise and patient
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


needs and values. Studies that attempt to find determinants of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


patient outcomes are generally experimental or quasi-
|\ |\ |\ |\ |\ |\


experimental. They may be used to guide EBP but do not |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


completely define it. EBP is a combination of guidelines and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


specific patient needs and values. Quantitative and qualitative
|\ |\ |\ |\ |\ |\ |\ |\

,studies applied to the evaluation of patient outcomes are part of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


EBP but do not completely define EBP.

The nurse is collecting data about the sleep patterns of breastfed
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


babies as part of a larger research study. Which research method
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


will the nurse use when collecting data for this study?
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\




a. Control
|\




b. Description
|\




c. Explanation
|\ |\




d. Prediction - CORRECT ANSWERS ✔✔Answer: Description
|\ |\ |\ |\ |\ |\




Rationale: Description involves identifying and understanding the
|\ |\ |\ |\ |\ |\


nature of nursing phenomena and the relationships among these
|\ |\ |\ |\ |\ |\ |\ |\ |\


phenomena. Control can be described as the ability to write a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


prescription to produce the desired results. Explanation clarifies
|\ |\ |\ |\ |\ |\ |\ |\


the relationships among phenomena and identifies why certain
|\ |\ |\ |\ |\ |\ |\ |\


events occur. Through prediction, the probability of a specific
|\ |\ |\ |\ |\ |\ |\ |\ |\


outcome can be estimated in a given situation.
|\ |\ |\ |\ |\ |\ |\




The nurse is participating in a study and is collecting data
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


identifying the number of obese adults whose parents were also
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


obese or overweight. Which research method is being used in
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


this study?|\




a. Control
|\

,b. Description
|\




c. Explanation
|\




d. Prediction - CORRECT ANSWERS ✔✔Answer: Prediction
|\ |\ |\ |\ |\ |\




Rationale: Through prediction, the probability of a specific
|\ |\ |\ |\ |\ |\ |\ |\


outcome can be estimated in a given situation. By knowing the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


percentage of parents of obese adults who were obese, the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


probability of predicting this may be calculated. Control indicates
|\ |\ |\ |\ |\ |\ |\ |\ |\


the ability to use a
|\ |\ |\ |\




prescribed intervention to produce the desired results.
|\ |\ |\ |\ |\ |\ |\


Description involves identifying and understanding the nature of
|\ |\ |\ |\ |\ |\ |\ |\


nursing phenomena and the relationships among these
|\ |\ |\ |\ |\ |\ |\


phenomena. Explanation clarifies the relationships among |\ |\ |\ |\ |\ |\


phenomena and identifies why certain events occur. |\ |\ |\ |\ |\ |\




The nurse reviews a study in which adherence to an asthma
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


action plan is compared among groups of young adults who
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


received different asthma education. Which research method
|\ |\ |\ |\ |\ |\ |\


does this represent?
|\ |\




a. Control
|\




b. Description
|\




c. Explanation
|\




d. Prediction - CORRECT ANSWERS ✔✔Answer: Explanation
|\ |\ |\ |\ |\ |\

, Rationale: Explanation clarifies the relationships among
|\ |\ |\ |\ |\ |\


phenomena and identifies why certain events occur. Control |\ |\ |\ |\ |\ |\ |\ |\


indicates the ability to use a prescribed intervention to produce
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


the desired results. Description involves identifying and
|\ |\ |\ |\ |\ |\ |\


understanding the nature of nursing phenomena and the |\ |\ |\ |\ |\ |\ |\ |\


relationships among these phenomena. Through prediction, the |\ |\ |\ |\ |\ |\ |\


probability of a specific outcome can be estimated in a given
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


situation.


A nurse manager is interested in learning which attitudes among
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


staff nurses may indicate relative risk of needle-stick injuries. To
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\

|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


study?


a. Control|\




b. Description
|\




c. Explanation
|\
