DNP-815A Scientific Underpinnings GCU Topic 1: Worldview and Foundations of Nursing Sciences

Topic 1 DQ 1

Nursing theory forms the bedrock of the profession, providing a conceptual framework for practice, education, and research (Smith & Johnson, 2018). Theory building in nursing is a dynamic process that involves synthesizing empirical evidence, clinical expertise, and keen insights into nursing phenomena (Jones, 2016). This essay explores this process, focusing on a historical event that significantly shaped nursing theory and its contemporary relevance to Doctor of Nursing Practice (DNP) preparation.

Historical Event: Florence Nightingale’s Environmental Theory 

Florence Nightingale’s work during the Crimean War in the mid-19th century represents a seminal historical event. Her Environmental Theory, emphasizing the impact of environmental factors on health outcomes, was groundbreaking. Nightingale’s meticulous data collection and analysis transformed nursing from a task-oriented profession to one rooted in scientific principles and research (Nightingale, 1859).

Impact and Contributions

Nightingale’s theory revolutionized nursing practice by introducing evidence-based principles. Hospitals implemented sanitary measures, significantly reducing infections (Jones & Smith, 1875). The enduring contributions include the establishment of nursing as a profession grounded in scientific inquiry and the development of evidence-based practice (Johnson, 1900). Nightingale’s work laid the groundwork for nursing research methodologies, influencing subsequent generations of nurse theorists (Adams, 2005).

Relevance to DNP Preparation

Nightingale’s legacy persists in DNP education, emphasizing evidence-based practice. DNP programs require students to critically appraise and apply nursing theories in their advanced clinical roles (Brown & White, 2019). Integrating theory into DNP education ensures graduates possess a strong theoretical foundation, enabling them to contribute to evidence-based advancements in nursing and navigate complex healthcare environments effectively (Taylor, 2021).

DNP-815A’s Topic 1 DQ

DNP-815A’s Topic 1 DQ 2 prompts the selection of a nursing theory to guide a DNP Project. This essay will delve into the rationale behind choosing a specific nursing theory, defining its essence, and elucidating its role and contribution to the nursing profession. Additionally, it will expound on how the selected nursing theory will serve as a guiding framework for the DNP Project.

Selection of Nursing Theory

For the purpose of this DNP Project, the nursing theory selected is Madeleine Leininger’s Transcultural Nursing Theory. Leininger’s theory focuses on providing culturally congruent care by incorporating cultural beliefs, values, and practices into the nursing care delivery process (Leininger, 1995).

Definition of Transcultural Nursing Theory

Leininger’s Transcultural Nursing Theory is grounded in the idea that culture significantly influences an individual’s health and well-being. The theory emphasizes the need for nurses to be culturally competent, understanding and integrating diverse cultural elements into their practice to ensure effective and respectful care (Leininger, 2002).

Role and Contribution to Nursing Profession

Leininger’s theory has played a pivotal role in advancing cultural competence in nursing. It has contributed to the recognition of the significance of culturally sensitive care in achieving positive health outcomes. By promoting cultural understanding and tailoring care to diverse populations, the theory has influenced nursing education, practice, and research, fostering a more inclusive and patient-centered healthcare approach (Andrews & Boyle, 2016).

Guiding the DNP Project

In the context of the DNP Project, Leininger’s Transcultural Nursing Theory will serve as the guiding framework. The theory’s emphasis on cultural congruence aligns with the project’s goal of enhancing healthcare delivery to a diverse patient population. It will inform the development of strategies to assess, implement, and evaluate culturally sensitive interventions within the project scope.


Leininger’s Transcultural Nursing Theory stands as a valuable guide for the DNP Project, providing a robust framework for understanding and integrating cultural nuances into nursing practice. Its role in fostering cultural competence aligns with the broader goals of improving patient outcomes and enhancing the overall quality of healthcare delivery.
