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 ✅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 ✅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 ✅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.

c. Explanation
d. Prediction ✅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.

d. Prediction ✅Answer: Prediction
Rationale: Through prediction, the probability of a specific outcome can be estimated in a given
situation. 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

are used with randomly assigned patients to measure differences in postoperative recovery time. Which
method of study is this?
a. Control
b. Correlation
c. Description
d. Explanation ✅Answer: Control
, Rationale: Control indicates the ability to use a prescribed intervention to produce the desired results.

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 exploring experiences of nurses' decision-making processes regarding
reporting a medical error. Which research method does this represent?
a. Control
b. Description
c. Explanation
d. Prediction ✅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.
Which study exemplifies qualitative research?
a. A study that evaluates appetite among residents of a long-term care facility and correlates this data
