Answer to Question 1
Ans: A
Critical thinking is defined as a systematic way to form and shape one's thinking. It functions purposefully and exactingly. It is thought that is disciplined, comprehensive, based on intellectual standards, and, as a result, well-reasoned (Paul, 1993, p. 20).
Answer to Question 2
Ans: B
Scientific problem solving is a systematic, seven-step, problem-solving process that involves (1) problem identification, (2) data collection, (3) hypothesis formulation, (4) plan of action, (5) hypothesis testing, (6) interpretation of results, and (7) evaluation, resulting in conclusion or revision of the study. This method is used most correctly in a controlled laboratory setting but is closely related to the more general problem-solving processes commonly used by health care professionals as they work with clients, such as the nursing process.
