Introduction to TFN

The lecturer introduces TFN (Theoretical Foundations in Nursing), NCM 100, a 3-unit course. Students are advised to prepare for a long quiz next week. The course objectives include understanding major nursing theories (like Nightingale, Orem, Peplau), analyzing theoretical concepts, applying theories in clinical scenarios, and critically evaluating their relevance in current nursing practice.

Nursing theory provides a framework for practice, acting as a professional compass for assessment, planning, implementation, and evaluation of care. It enhances patient care by promoting holistic, individualized approaches and supports evidence-based practice by forming the basis for research questions. Additionally, it guides nursing research and education by shaping curricula and providing a language for scientific investigation.

The course will utilize various instructional methods such as lectures, presentations, group discussions, and audiovisual materials. It will be delivered in a blended format, including both online and face-to-face sessions. Assigned readings, written outputs, and case studies will be used to help students actively engage with the material and apply theoretical concepts in practical contexts.

Students are expected to commit to their own learning and support their peers, fostering a respectful and inclusive environment. Active participation, preparation, and thoughtful engagement in discussions are crucial. Proper online etiquette is emphasized, including careful reading of classmates' posts, clear and respectful communication, avoiding derogatory remarks, and offering constructive disagreement. Students should be patient when awaiting replies from instructors and check course materials for answers before asking questions.

The grading policy is 60% for class participation (attendance, quizzes, activities, recitation) and 40% for periodical exams (prelim, midterm, final). A detailed example illustrates how the final grade is computed by averaging the midterm and tentative final grades. The payment schedule involves four installments, each due before major examinations (prelim, midterm, final). Grades will not be encoded if payments are not updated or are submitted late, resulting in an 'incomplete A'. An 'incomplete B' is given for unfulfilled academic requirements. Valid excuses for missed academic work require a medical certificate or a death certificate of an immediate family member.

The lecture shifts to the first main topic: the introduction, definitions, and history of nursing theories. Nursing theories provide the 'why' behind nursing actions, guiding decisions and providing a framework for patient care. They are the foundation of nursing knowledge, offering a structured framework for clinical practice, education, and research. Without theory, actions would lack consistency and purpose, making it difficult to differentiate nursing from other health professions. Concepts are the building blocks of theories, such as 'health,' 'pain,' or 'caring'.

Key terms are defined: a 'theory' is a set of concepts, definitions, relationships, and assumptions explaining a phenomenon. A 'nursing theory' is a specific framework developed to explain, define, and guide nursing practice, created by nurses for nurses. 'Concepts' are abstract ideas like 'health' or 'caring'. A 'paradigm' is a broad pattern of beliefs influencing what questions are asked and how answers are sought in nursing. The 'metaparadigm of nursing' is the highest level of abstraction, encompassing four central concepts: person, health, environment, and nursing.

Nursing theories serve several purposes: they define the nursing profession, clarifying its unique identity focused on caring and wellness; they provide a basis for clinical decision-making, offering structured guidance for actions; they guide nursing education and research by shaping curricula and providing frameworks for investigation; and most importantly, they aim to improve patient care outcomes by encouraging thoughtful, person-centered, and evidence-based practice.

The historical evolution of nursing theory is explored. Pre-1950s, nursing was based on practice and tradition. The 1950s-1970s saw the emergence of formal theories from pioneers like Florence Nightingale (environmental theory), Virginia Henderson (needs theory), Dorothea Orem, and Hildegard Peplau. The 1980s-1990s witnessed an 'explosion' of theoretical development, categorizing theories into grand, middle-range, and practice-level. From 2000 to the present, nursing theory emphasizes evidence-based practice, global perspectives, cultural diversity, health equity, and social determinants of health.

Five influential figures in nursing theory are highlighted: Florence Nightingale (Environmental Theory), Virginia Henderson (Need Theory with 14 basic human needs), Abdellah (21 Nursing Problems Theory focusing on patient-centered care), Hildegard Peplau (Interpersonal Relations Theory, emphasizing nurse-patient communication), and Dorothea Orem (Self-Care Deficit Theory, addressing when nursing is needed to bridge self-care gaps). Each contributed unique perspectives that define and shape nursing practice.

In conclusion, nursing theories are vital for the profession's growth, defining its identity, and elevating its role in healthcare. They transform nursing from a task-oriented job into an analytical, evidence-based, compassionate discipline. Theories guide actions in practice, shape education, and provide frameworks for research to advance patient care. Understanding their history and definitions helps appreciate nursing's past and future, encouraging nurses to live out these theories through knowledge, skills, and a professional attitude.
