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.

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.
