MULTIPLE CHOICE
1. A nursing educator is explaining how the best clinical practices are determined. Which
statement best explains the purpose of evidence-based practice?
A. It ensures that all patients receive holistic care.
B. It provides a definite reason for providing care in a specific manner.
C. It prevents errors when care is being delivered.
D. It guarantees that care delivered is based on research.
ANS: B
Evidence-based practice is the use of the current best evidence in making patient care
decisions. It applies to all types of health care professionals. Currently there is no method
that can ensure that all patients receive holistic care, that all errors can be prevented, or
that a guarantee exists that care given is based on research.

2. Which question is a problem-focused trigger?
A. What is known about reduction of urinary tract infections in the older adult with
diabetes?
B. How can chronic pain best be described when the patient is nonverbal?
, C. How long can an intravenous catheter remain in place in an obese patient?
D. What measures can the nurse take to reduce the rising incidence of urinary tract
infections on the elder-care unit?
ANS: D
A problem-focused trigger is a question faced when caring for a patient or a trend seen in a
practice setting. In this example there is a problem (urinary tract infections) and a trend (on
the elder-care unit). The other questions are general information questions, not based on
what is happening in a specific area or to a group of specific patients in an area or relating to
an observed trend.

3. What does the “I” indicate in a “PICO” question?
A. Intervention of interest
B. Incorporation of concepts
C. Implementation by nursing
D. Interest of personnel
ANS: A
The “I” stands for intervention of interest, meaning what the nurse hopes to use in practice
and believes is worthwhile or valuable. This could be a treatment for a specific type of
wound or an approach on how to teach food preparation for a patient with impaired sight.

4. The nurse is conducting clinical research and needs to obtain relevant databases. Whom
should the nurse contact?
, A. The physician whose patients may be involved in the study
B. The medical librarian
C. The nurse manager of the unit where the study will be conducted
D. The director of nursing of the facility
ANS: B
The medical librarian is most knowledgeable regarding databases relevant to a study. The
other individuals will know about the study but do not have the knowledge regarding
relevant databases.

5. Which database contains clinical guidelines systematically developed for a specific set of
circumstances involving a specific patient population?
A. MEDLINE
B. CINAHL
C. Cochrane Data of Systematic Reviews
D. The National Guideline Clearinghouse
ANS: D
The National Guideline Clearinghouse is a database supported by the Agency for Healthcare
Research and Quality. It contains clinical guidelines systematically developed about a plan
of care for a specific set of clinical circumstances involving a specific patient population. The
others are not as specific and have broader application and references.

, 6. The nurse researcher is trying to determine the clearest type of research. Which type of
research would the nurse choose as the gold standard?
A. Randomized controlled trials
B. A qualitative study
C. A descriptive study
D. A case-controlled study
ANS: A
Individual randomized controlled trials are the gold standard for research. This type of
study establishes cause and effect and the best way for testing a therapy or an intervention.
The other types of studies are useful but do not give the same type of information as a
randomized controlled trial provides.

7. What is the nurse attempting to determine when critiquing the evidence?
A. If the potential study is ethical to conduct
B. If there is enough evidence to ask a PICO question and change practice
C. If there are any experts in the clinical area to be researched
D. If the study is cost-effective if a change in practice occurs
ANS: B
Once a literature search is complete and data gathered about the question, it is time to
critique the evidence. The critique tells the nurse if there is enough evidence to answer the
PICO question and change practice. The other questions are important to consider when
doing the study but are not applicable to critiquing the evidence.
