ANS: D r
Evidence-based practice (EBP) questions tend to arise from two sources: recurrent r r r r r r r r r r
r problemsor new knowledge. In the correct option, the increase in urinary tract
r r r r r r r r r r r
r infections indicates a trend or recurring problem in a specific group of patients. The
r r r r r r r r r r r r r
r other questions are general information questions, not based on what is happening in
r r r r r r r r r r r r
r a specific area or to a group of specific patients in an area or relating to an observed
r r r r r r r r r r r r r r r r r
r trend.
