Nursing theories enhance critical thinking skills in nursing students by providing a structured framework for analyzing patient care situations. By understanding the concepts and relationships outlined in various theories, students learn to assess situations systematically, evaluate evidence, and make informed decisions. For example, a student applying Peplau’s Interpersonal Relations Theory will critically assess the nurse-patient relationship and its impact on care outcomes. This analytical approach encourages students to question assumptions, explore alternative solutions, and justify their choices based on theoretical foundations. Furthermore, engaging with nursing theories fosters reflective practice, prompting students to consider their experiences and the underlying principles that guided their actions, ultimately leading to improved critical thinking and decision-making abilities.
