CHAPTER 1 INTRODUCTION TO NURSING RESEARCH
AND ITS IMPORTANCE IN BUILDING AN EVIDENCE-
BASED PRACTICE | LATEST 2026 | QUESTIONS AND
VERIFIED ANSWERS | GRADED A+
1. 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: ANS: A
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. DIF:
Cognitive level: Remembering (Knowledge)
2. 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: ANS: B
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. DIF: Cognitive
level: Understanding (Comprehension)
3. 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: ANS: D
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.
DIF: Cognitive level: Applying (Application)
4. 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
- ANSWER: ANS: C
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.
5. A nurse manager is interested in learning which attitudes among staff nurses may
indicate relative risk of needle-stick injuries. To study this, the nurse manager will
employ which method of study?
a. Control
b. Description
c. Explanation
d. Prediction
- ANSWER: ANS: D
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 identifies why certain events occur.
6. Which is the most important result of Florence Nightingale's data collection and
statistical analysis during the Crimean War?
a. Bringing awareness of the rigors of war to the general public in relation to care
practices
b. Developing a process for statistical analysis and nursing documentation
c. Identifying and defining the role of nurses in modern health care
d. Using clinical research to evaluate the need for sanitation, clean drinking water,
- ANSWER: ANS: D
Nightingale's research enabled her to instigate attitudinal, organizational, and social
changes, including the military's approach to the care of the sick and society's sense of
responsibility for testing public water, improving sanitation, and preventing starvation to
decrease morbidity and mortality rates. Bringing awareness of the rigors of war to the
public, developing a process for statistical analysis and nursing documentation, and
identifying and defining the role of nurses in modern health care were not the most
important results.
