In today’s health care arena, the nurse is faced with increasingly complex issues and situations resulting from advanced technology, greater acuity of patients in hospital and community settings, an aging population, and complex disease processes, as well as ethical and cultural factors. Traditionally, nurses have used a problem-solving approach in planning and providing nursing care. Today the decision-making part of problem solving has become increasingly complex and requires critical thinking. Definition of Critical thinkingCritical thinking is a multidimensional skill, a cognitive or mental process or set of procedures. It involves reasoning and purposeful, systematic, reflective, rational, outcome-directed thinking based on a body of knowledge, as well as examination and analysis of all available information and ideas. Critical thinking leads to the formulation of conclusions and the most appropriate, often creative, decisions, options, or alternatives. Critical thinking includes metacognition, the examination of one’s own reasoning or thought processes while thinking, to help strengthen and refine thinking skills. Independent judgments and decisions evolve from a soundknowledge base and the ability to synthesize information within the context in which it is presented. Nursing practice in today’s society mandates the use of high-level critical thinking skills within the nursing process. Critical thinking enhances clinical decision making, helping to identify patient needs and to determine the best nursing actions that will assist the patient in meeting those needs. Critical thinking and critical thinkers have distinctive characteristics. As indicated in the above definition, critical thinking is a conscious, outcome-oriented activity; it is purposeful and intentional. The critical thinker is an inquisitive, fair-minded truth seeker with an open-mindedness to the alternative solutions that might surface. Critical thinking Process: Rationality and InsightCritical thinking is systematic and organized. The skills involved in critical thinking are developed over time through effort, practice, and experience. Skills needed in critical thinking include interpretation, analysis, evaluation, inference, explanation, and self-regulation. Critical thinking requires background knowledge and knowledge of key concepts as well as standards of good thinking. The critical thinker uses reality-based deliberation to validate the accuracy of data and the reliability of sources, being mindful of and questioning inconsistencies. Interpretation is used to determine the significance of data that are gathered, and analysis is used to identify patient problems indicated by the data. The nurse uses inference to draw conclusions. Explanation is the justification of actions or interventions used to address patient problems and to help a patient move toward desired outcomes. Evaluation is the process of determining whether outcomes have been or are being met, and self-regulation is the process of examining the care provided and adjusting the interventions as needed. Critical thinking is also reflective, involving metacognition, active evaluation, and refinement of the thinking process. The critical thinker considers the possibility of personal bias when interpreting data and determining appropriate actions. The critical thinker must be insightful and have a sense of fairness and integrity, the courage to question personal ethics, and the perseverance to strive continuously to minimize the effects of egocentricity, ethnocentricity, and other biases on the decision making process. Components of Critical thinkingCertain cognitive or mental activities can be identified as key components of critical thinking. When thinking critically, a person will do the following:
Critical thinking requires going beyond basic problem solving into a realm of inquisitive exploration, looking for all relevant factors that affect the issue, and being an “out-of-the-box” thinker. It includes questioning all findings until a comprehensive picture emerges that explains the phenomenon, possible solutions, and creative methods for proceeding. Critical thinking in nursing practice results in a comprehensive patient plan of care with maximized potential for success. Critical thinking In Nursing PracticeUsing critical thinking to develop a plan of nursing care requires considering the human factors that might influence the plan. The nurse interacts with the patient, family, and other health care providers in the process of providing appropriate, individualized nursing care. The culture, attitude, and thought processes of the nurse, the patient, and others will affect the critical thinking process from the data-gathering stage through the decision-making stage; therefore, aspects of the nurse-patient interaction must be considered. Nurses must use critical thinking skills in all practice settings—acute care, ambulatory care, extended care, and in the home and community. Regardless of the setting, each patient situation is viewed as unique and dynamic. The unique factors that the patient and nurse bring to the health care situation are considered, studied, analyzed, and interpreted. Interpretation of the information presented then allows the nurse to focus on those factors that are most relevant and mostsignificant to the clinical situation. Decisions about what to do and how to do it are then developed into a plan of action. Fonteyn (1998) identified 12 predominant thinking strategies used by nurses, regardless of their area of clinical practice: Recognizing a pattern
Fonteyn further identified other, less prominent thinking strategies the nurse might use:
These thought processes are consistent with the characteristics of critical thinking and cognitive activities discussed earlier. Fonteyn asserted that exploring how these thinking strategies are used in various clinical situations, and practicing using the strategies, might assist the nurse–learner in examining and refining his or her own thinking skills. Throughout the critical thinking process, a continuous flow of questions evolves in the thinker’s mind. Although the questions will vary according to the particular clinical situation, certain general inquiries can serve as a basis for reaching conclusions and determining a course of action. When faced with a patient situation, it is often helpful to seek answers to some or all of the following questions in an attempt to determine those actions that are most appropriate:
