responsible for research consent. If patients who have agreed to participate exhibit ambivalence or

Ans: C pzp z




Feedback: Patient preferences should be integrated into EBP and considered alongside research
p zp z pzpz p zp z pzp z pzpz p zp z pzpz p zp z p zp z p zp z pzp z




evidence and the nurses clinical expertise; evidence does not trump the patients preferences. The
pzp z pzpz pzpz pzpz pzpz pzpz pzpz pzpz pzp z pzpz pzpz pzpz pzp z pzpz




family should be involved, but thisisnot an explicit dimension ofEBP. Similarly, explaining the
pzp z pzpz pzpz pzpz pzp z pzpz pz z
p pzp z pzpz pzpz pzpz z
