NRP513 Assessment 1 History of Nursing Science and Evidence Based Practice

Scientific Paradigms of Nursing Science

The Positivism Paradigm and the Constructivist Paradigm are the two paradigms that Polit and Beck (2019) discuss in nursing and research. The Positivism Paradigm is the first paradigm. According to Polit and Beck (2019), positivism values objectivity and presupposes order and a single reality.

Quantitative research is used by positivists, which means that data are gathered numerically and analyzed statistically. Positivism and empiricism emphasize objective methods, a fixed and controlled environment free of bias, and little to no contact between the researcher and the subject. 

They want to test whether a hypothesis is true or false. Their data can be quantified and either demonstrates truth or falsity by demonstrating a measurable outcome. NRP 513 Assessment 1 History of Nursing Science and Evidence Based Practice

According to McEwen and Willis (2019), the Constructivist Paradigm, which is also regarded as a perceived view of science, states that, as opposed to artificially invented descriptions, science centers on collectively lived experiences, human interpretation, and learned reality.

Each person’s experience and reality are distinct, so there is no universal truth. According to Polit and Beck (2021), Constructivist research yields rich, top to bottom data, experiences are acquired, new inquiries arise. Constructivism is used in qualitative research, which is based on real-world, first-hand experiences, working with the subjects, and gaining insight.

According to Polit and Beck (2021), despite the differences between the two paradigms, they share a few characteristics: they both aim to answer questions and solve problems, they both gather empirical evidence using their senses, they both require human cooperation, they both work within ethical constraints, and finally, they both have limitations. NRP 513 Assessment 1 History of Nursing Science and Evidence Based Practice

Nursing Theory and Research

Nursing Theory and Research According to McEwen and Beck (2019), nursing theory provides structure, organization, and a methodical approach to data collection in order to describe, explain, and assist in predicting nursing practice. 

According to McEwen and Beck (2019), nursing theory aids in the purposeful and focused practice of nursing, as well as the identification of goals and outcomes, thereby assisting in the direction of nursing care.

Helps to define boundaries and also makes nursing care more coordinated and less dispersed. Nursing hypothesis and nursing research remain closely connected, nursing hypothesis prompts nursing research which helps guide nursing in understanding consideration, nursing schooling, and to prove Base practice. NRP 513 Assessment 1 History of Nursing Science and Evidence Based Practice

 It will lead to guiding nursing toward what is best in the field of nursing depending on the type of research that is being conducted and the research style that is utilized.

Evidence-Based Practice Approach for Advanced Nursing Practice

McEwen and Beck (2019) say that the Evidence-Based Practice Approach for Advanced Nursing Practice is based on the idea that individual clinical expertise with the best clinical evidence from a systematic research should take precedence over tradition and belief. NRP 513 Assessment 1 History of Nursing Science and Evidence Based Practice

According to McEwen and Willis (2019), the EBP approach to advanced nursing practice entails identifying a problem, locating literature-based research, systematically evaluating the literature-based research to evaluate the evidence, and then implementing the appropriate treatment or intervention. Since Florence Nightingale’s time, Evidenced-Based Practice (EBP) has developed and continues to influence nursing practice and perception.
