Knowledge Check #2 Test
Question 1 4 pts
A nursing student is critiquing a study for her nursing research class. She feels like the study findings
are generalizable to other settings and populations because:
the sampling criteria for subjects was very narrow and restrictive, to provide a homogenous
sample.
the review of literature was extensive and included a conceptual framework.
there is consistency of the current study's finding with that found in previous research studies.
it has a small sample size which was obtained by convenience.
Question 2 4 pts
In the Iowa Model of Evidence Based Practice, if a nurse brings forward a new research article with
ideas that she/he would like to consider implementing on the unit, this would be considered to be:
an opportunity to monitor and analyze structure, processes, and outcome data.
a problem-focused trigger.
an opportunity for comparative evaluation between two units.
a knowledge-focused trigger.
Question 3 4 pts
What statistical test would you use to determine a relationship between hours worked by nurses in a
week and medication errors?
X - chi squared
2
r- Pearson product moment
frequency distribution
standard deviation
Question 4 4 pts
A power analysis is conducted to:
test for internal validity.
set the level of significance.
determine a reliability coefficient.
estimate a sample size.
, Question 5 4 pts
According to Makic et al (2014) what is the best way to confirm placement of a feeding tube when
radiography is not available in a pediatric population?
detecting carbon dioxide using colometry or capnography
testing aspirate for pH and color

70% 80% 60% 90%
Question 7 4 pts
According to Peterson et al (2014), in AACN's 2012 rating scale level system, grouping together A, B,
and C levels of evidence would result in
experimental levels of evidence for practice.
non-experimental levels of evidence for practice.
evidence-based recommendations for practice.
expert opinion or manufacturer's recommendations for practice.
Question 8 4 pts
Content validity is defined as:
maintaining research controls as indicated in the study design and hypotheses.
measuring stability, equivalence, and homogeneity of a questionnaire.
including all of the major elements relevant to the construct being measured.
reviewing the inferential and demographics data of the sample.
Question 9 4 pts
In this example of a PICO question: “In elderly hospitalized patients, what is the effect of hourly
nursing rounds on reducing falls compared with the standard practice of bedside call lights and low
bed positioning?” Hourly nursing rounds represent what element of the PICO format?
I – intervention P- population C – comparison O - outcome
