Evidence-based practice is the use of the current best evidence in making patient care

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.

TESTBANKWORLD.ORG
, a. Randomized controlled trials
4
b. A qualitative study

same type of information as a randomized controlled trial provides.
