This report provides a critical analysis of the factors that enable nurses to learn in a practice setting. It begins by establishing a conceptual frame of nursing knowledge based on Carper's four sources: empirical, ethical, personal, and aesthetic knowledge, along with contextual knowledge encompassing procedural, material, organizational, and social dimensions. The report then examines individual factors such as curiosity, motivation, job satisfaction, age, experience, and education level, highlighting their impact on competence development. Contextual factors, including the intensive care environment and prevailing culture, are discussed, emphasizing the importance of appropriate timing for training and the nurse's relationship with physicians. Organizational factors, such as shared decision-making, positive leadership, and mentoring support, are also explored. The analysis concludes that practical knowledge is acquired through observation and interaction with expert nurses, while perceptual knowledge stems from direct experiences in care situations, ultimately demonstrating how individual, contextual, and organizational factors collectively influence nurses' learning abilities in practice.
