2 Nursing theories are crucial in shaping and guiding nursing practice, education, and research. Grand nursing theories provide an inclusive conceptual structure, while middle-range nursing theories offer more specific guidance within distinct circumstances. This study will explore applying a grand nursing theory and a middle-range nursing theory in research articles. The analysis will scrutinize the theories employed in these studies and deliberate on the possible consequences of their applications in impelling the nursing field forward and enlightening advanced nursing practice. Background Information: Grand, Middle, and Practice Theories Grand nursing theories serve as expansive and abstract frameworks crucial in comprehending fundamental principles and relationships within nursing. These theories have far- reaching implications, directing research endeavors on a global level and informing a wide- ranging outlook on the overarching facets of nursing. In contrast, middle-range nursing theories exhibit a more directed and specific nature, acting as a connective link between grand theories and the practical application of nursing in real-world scenarios. These theories delve more complexly into particular facets of nursing, offering a more understated comprehension. While grand and middle-range theories provide a comprehensive view of nursing, operational theories hold equal importance, although not expressly emphasized in the provided articles. Practice theories are intricately interlaced into specific situations and hold significance in guiding nursing interventions. These theories provide nurses with valid perceptions and operational instructions, guaranteeing that theoretical understanding is proficiently utilized amidst the ever-changing and multifaceted patient care settings. The combination of broad, intermediate, and practical theories collectively contributes to the comprehensive growth and implementation of nursing knowledge, promoting a comprehensive perspective of the profession
