It involves reasoning and purposeful, systematic, reflective, rational, outcome-directed thinkingbased on a body of knowledge, as well as examination and analysis of all available information and ideas. Critical thinking leads tothe formulation of conclusions and the most appropriate, oftencreative, decisions, options, or alternatives (Ignatavicius, 2001;Prideaux, 2000).
Critical thinking includes metacognition, the examination of one’s own reasoning or thought processes while thinking, to help strengthen and refine thinking skills (Wilkinson, 2001). Independent judgments and decisions evolve from a sound knowledgebase and the ability to synthesize information within the contextin which it is presented. Nursing practice in today’s society mandates the use of high-level critical thinking skills within the nursing process.
