OI1. Evidence-based practice is a problem- sj sj sj sj
solving approach to making decisions about patient care that is grounded in:
sj sj sj sj sj sj sj sj sj sj sj
a. the latest information found in textbooks.
sj sj sj sj sj
b. systematically conducted research studies. sj sj sj
c. tradition in clinical practice. sj sj sj
d. quality improvement and risk-management data. sj sj sj sj
ANS: B s j
The best evidence comes from well-
sj sj sj sj sj
designed, systematically conducted research studies described in scientific journals. Portions of a
sj sj sj sj sj sj sj sj sj sj sj
textbook often become outdated by the time it is published. Many health care settings do not hav

e a process to help staff adopt new evidence in practice, and nurses in practice settings lack easy a
sj sj sj sj sj sj sj sj sj sj sj sj sj sj sj sj sj sj
ccess to risk- sj sj
management data, relying instead on tradition or convenience. Some sources of evidence do not
sj sj sj sj sj sj sj sj sj sj sj sj sj sj
originate from research. These include quality improvement and risk-
sj sj sj sj sj sj sj sj
management data; infection control data; retrospective or concurrent chart reviews; and clinician
sj sj sj sj sj sj sj sj sj sj sj
s‘ expertise. Although
sj sj
non–research-
based evidence is often very valuable, it is important that you learn to rely more on research-
sj sj sj sj sj sj sj sj sj sj sj sj sj sj sj sj
based evidence. sj

sj sj sj sj sj sj sj sj
a. standardized for all. sj sj
b. unhampered by patient culture. sj sj sj
c. variable according to the situation. sj sj sj sj
d. safe from the hazards of critical thinking. sj sj sj sj sj sj

4. A well-developed PICOT question helps the nurse:
sj sj sj sj sj sj
a. search for evidence. sj sj
b. include all five elements of the sequence. sj sj sj sj sj sj
c. find as many articles as possible in a literature search.
sj sj sj sj sj sj sj sj sj
d. accept standard clinical routines. sj sj sj
ANS: A s j
The more focused a question that you ask is, the easier it is to search for evidence in the scienti

fic literature. A well-
sj sj sj
designed PICOT question does not have to include all five elements, nor does it have to follow
sj sj sj sj sj sj sj sj sj sj sj sj sj sj sj sj
the PICOT sequence. Do not be satisfied with clinical routines. Always question and use critic

al thinking to consider better ways to provide patient care.
