SIMPLIFIED NURSING RESEARCH | OVERALL DISCUSSION (PART 1) | NURSING EXAM REVIEW | INDAY RN

Summary

This video provides an engaging introduction to nursing research, explaining its purpose, significance, and methods. It highlights how nursing research enhances knowledge, promotes health, and demonstrates the value of nursing in society. The video details different methods of acquiring knowledge, the definitions of independent, dependent, and intervening variables, and the structured versus unstructured approaches. It also explains the classifications of research based on approach (quantitative, qualitative, mixed) and purpose (basic or applied), along with experimental and non-experimental designs, including manipulation, randomization, and control. Overall, it offers a clear, simplified overview of essential concepts for aspiring nurses and researchers.

Takeaways

• 😀 Nursing research is a systematic inquiry aimed at developing, refining, and expanding knowledge to improve health care and nursing practice.
• 😀 Research in nursing helps demonstrate the value of nursing in society, supporting both clinical and administrative practices.
• 😀 Methods of acquiring knowledge can be unstructured (tradition, authority, intuition, experience, trial and error) or structured (inductive/deductive reasoning, problem-solving, scientific method).
• 😀 Variables are key in research: independent variables are the cause, dependent variables are the effect, and intervening variables influence the relationship between the two.
• 😀 Research can be classified based on approach (quantitative, qualitative, mixed) or purpose (basic or applied).
• 😀 Quantitative research focuses on numerical data, objectivity, measurement, and statistical analysis.
• 😀 Experimental quantitative research involves manipulation, randomization, and control, with subtypes including true experimental, quasi-experimental, and pre-experimental designs.
• 😀 Non-experimental research observes natural phenomena without manipulation or control, including descriptive, correlational, developmental, and survey designs.
• 😀 Qualitative research explores human experiences and phenomena through designs like phenomenological, grounded theory, ethnographical, historical, case studies, and action research.
• 😀 Understanding research approach, type, and methodology is essential for collecting data accurately and applying findings effectively in nursing practice.

Q & A

What is the main purpose of nursing research?

The main purpose of nursing research is to develop, refine, and expand knowledge about health, promote health across the lifespan, improve care for individuals with problems and disabilities, and demonstrate the value of nursing in society.

What is the difference between structured and unstructured methods of acquiring knowledge in nursing?

Unstructured methods, such as tradition, authority, intuition, experience, and trial and error, lack a systematic path. Structured methods, including inductive and deductive reasoning, assembled information, problem-solving, and the scientific method, follow a systematic, organized approach to acquire knowledge.

What are the three main types of variables in nursing research?

The three main types of variables are: Independent Variable (presumed cause), Dependent Variable (presumed effect or primary interest), and Intervening Variable (mediates or influences the relationship between the independent and dependent variables).

How is quantitative research defined in the context of nursing research?

Quantitative research focuses on discovering facts about social phenomena using numerical investigation and measurement. It emphasizes objectivity, validity, accuracy, and statistical analysis to understand relationships and effects.

What is the difference between experimental and non-experimental quantitative research?

Experimental research involves manipulation of variables, randomization, and control to determine cause-effect relationships. Non-experimental research observes naturally occurring phenomena without manipulation or control.

What are the three types of experimental quantitative research?

The three types are: True Experimental (manipulation, randomization, and control present), Quasi-Experimental (manipulation present with either randomization or control), and Pre-Experimental (only manipulation present, without randomization or control).

Can you provide an example of manipulation in experimental research?

An example of manipulation is administering a painkiller to a patient in pain to observe the effect on pain relief. The painkiller is the independent variable, and the patient's pain level is the dependent variable.

What are the four types of non-experimental quantitative research designs?

The four types are: Descriptive (observe, document, describe), Correlational (examines relationships between variables without intervention), Developmental (focuses on variables at a specific time), and Survey (collects opinions or data numerically).

How is qualitative research different from quantitative research?

Qualitative research focuses on understanding experiences, meanings, or phenomena rather than numerical measurement. It includes approaches such as phenomenological, grounded theory, ethnographic, historical, case studies, and action research.

What is a research approach and why is it important?

A research approach is the overall design including assumptions, inquiry process, type of data collected, and measurement of findings. It is important because it determines how knowledge will be systematically acquired, analyzed, and interpreted in nursing research.

What is mixed-method research in nursing?

Mixed-method research combines both quantitative and qualitative approaches. Types include convergent, explanatory, exploratory, and embedded designs, allowing researchers to gather numerical data and explore experiences or phenomena in depth.

What is the difference between basic and applied research in nursing?

Basic research aims to expand general knowledge without immediate practical application, whereas applied research seeks practical solutions to specific health or nursing-related problems.
