Questions and CORRECT Answers
EBP (evidence based practice) - CORRECT ANSWER - The 7 steps of _____ (acronym only) are:
Step 0: Cultivate a spirit of inquiry
Step 1: Ask clinical questions in a PICOT format
Step 2: Search for the best evidence
Step 3: Critically appraise the evidence
Step 4: Integrate the evidence with clinical expertise and patient preferences and values
Step 5: Evaluate the outcomes of the practice decisions or changes based on evidence
Step 6: Disseminate EBP results
evidence-based practice - CORRECT ANSWER - The conscientious integration of best research
evidence with clinical expertise, patient values and needs in
the delivery of high-quality, cost effective health care describes _____ (thr-ee words).
variable - CORRECT ANSWER - A factor that can be controlled or changed in an experiment is a
____.
dependent - CORRECT ANSWER - The variable which is hypothesized to rely upon or be caused
by another variable is the [ dependent / independent ] variable.
independent - CORRECT ANSWER - The variable that is believed to be the "cause" or "influence"
is the [ dependent / independent ] variable.
confounding - CORRECT ANSWER - Extraneous variables are also knows and _____ variables.
These variables cloud the relationship between the dependent and independent variables.

measures the phenomena in the first place or reflects the abstract construct being examined is [ reliability
/ validity ].
descriptive - CORRECT ANSWER - Statistics which describe and synthesise data and show
patterns and trends are [ descriptive / inferential ] statistics.
inferential - CORRECT ANSWER - Statistics which permit the investigator to infer whether
relationships noted in a sample might occur in a larger population are [ descriptive / inferential ].
central tendency - CORRECT ANSWER - Mean (average), median (exact middle) and mode
(occurs most frequently) are measures of _____.
P-values (probability level) - CORRECT ANSWER - Statisticians use _____ (two words) to
measure probability, the likelihood of a particular outcome.
standard deviation - CORRECT ANSWER - The spread of data from a mean values is the ____
(two words).
population - CORRECT ANSWER - During the 7 steps of evidence-based practice, the nurse asks
questions in PICOT format, which stands for:
P: _____ of interest
