NURS406 EIP Exam 2 Questions With
Correct Answers
What is a systematic review? - answer✔A structured way of finding the best research evidence
from SEVERAL articles in the literature
-finding articles, appraising & synthesizing them (putting them together in a meaningful way) in
a RIGOROUS manner
What is a meta-analysis? - answer✔Pooling the statistics together from many studies, usually
with a forest plot, which we'll discuss
What is a meta-synthesis? - answer✔Systematically reviewing QUALITATIVE reserach findings
Meta-summary: summarizing the findings from qualitative studies
What is an integrative review? - answer✔Includes qualitative & quantitative studies
Why can results from a meta-analyses be difficult to decipher? - answer✔They may include
forest plots
What is a forest plot? - answer✔Simply a picture of results of several studies & always includes
a "summary" diamond that shoes you the results of the studies, all complied together
What does the size of the shape mean in a forest plot? - answer✔Size of each of the diamonds,
or squares or triangles that are used show how much WEIGHT is given to that particular study
What does confidence (CI) mean? - answer✔If you have a 95% CI in the results of a study, it
means that 95% of the time, the population's mea will fall within the range that they give. It will
be written as 95% CI (range = 15=25)
This means that if this study is repeated it is expected that the scores will fall between 15 & 25
What do horizontal lines mean in a forest plot? - answer✔CI: describes the range of the effect
of the intervention that is being studied

Which is better narrow or wider CI? - answer✔Narrower: if there is a lot of variation in the
study responses, then you'll see a wider range
What do squares to the left of the line in a forest plot mean? - answer✔Indicate that the
intervention was better than the Tx that the control group received. (Look at the bottom of the
chart to fully interpret it
-if the outcome is something that we DO NOT want to see (like death, pain or infection) then a
square to the right of the line means that the intervention was WORSE than the control
What are the strongest evidence types? - answer✔Meta-analysis
Integrative reviews
Experimental studies, like RCTs- what's an RCT?
What are the weakest evidence types - answer✔Descriptive surveys
Qualitative studies
Correlational studies
Quasi-experimental studies
When should the prisms model be used? - answer✔For critical appraisal of published
systematic reviews & meta-analysis
What are descriptive statistics? - answer✔Gather, sort, summarize numerical data into one or
two simple numbers that "describe" your sample, or "describe" your findings
-central values
-dispersion from the means
-summary statistics
What is inferential statistics? - answer✔Infer back to the population that you want to make a
difference for
-probability
-confidence Intervals
How confident are we that we are right?
-P values, CI
