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 for initiating the evidence-based practice method
in nursing care?
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 IV catheter remain in place in a patient with obesity?
d. What measures can the nurse take to reduce the rising incidence of urinary tract
infections on the older adult care unit?
ANS: D
Evidence-based practice (EBP) questions tend to arise from two sources: recurrent problems
or new knowledge. In the correct option, the increase in urinary tract infections indicates a
trend or recurring problem in a specific group of patients. 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

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.
