Answer to Question 1
A
The fourth component of the critical thinking model is attitudes. Paul (1993) identifies 11 atti-tudes that are central features of a critical thinker of which risk taking, creativity, and integrity are examples. Kataoka-Yahiro and Saylor (1994) describe critical thinking competencies as the cognitive processes a nurse uses to make judgments about the clinical care of patients. There are three competencies: general critical thinking (scientific method, problem solving, and decision making), specific critical thinking in clinical situations (clinical inference, diagnostic reasoning, and clinical decision making), and specific critical thinking in nursing (nursing process). The standards for critical thinking include intellectual standards and professional standards. The nursing process is a five-step approach that incorporates diagnostic reasoning and clinical deci-sion making.
