About critical thinking.

Although a universally accepted definition of critical thinking has yet to be determined, there is much discussion in the literature about its meaning and, in particular, how it can be expressed in professional nursing practice. The simultaneous use of related terms such as reflective thinking, problem solving and clinical decision-making contributes to the lack of clarity around exactly what critical thinking is and, subsequently, how it can be taught and evaluated in the clinical setting. The purpose of this article is to provide an overview of the various components of critical thinking and to discuss barriers, facilitators and strategies that can enhance nurses' attainment of this core competency. Few would argue that registered nurses today must be able to think critically in order to effectively communicate a nursing perspective that reflects a meaningful clinical grasp and preparedness to act.
