Q

Qualitative Method

A

◦Discovery of meaning rather than cause and effect.
◦Desire to understand a human or social problem.
◦Conducted in a natural setting, sampling is often purposive
◦Reality is defined by the subject / informant. ◦Researcher interacts with those being studied, the distance between researcher and subject is minimized
◦Result of research may raise more questions than answers.
◦Emphasis is on achieving an understanding

Q

Quantitative method

A

Aim is to answer by either either proving or disproving a hypothesis using numeric measurement and observation

◦Directed at the discovery of relationships and cause and effect.
◦Formal, rigorous, systematic, objective process to obtain information and control for error
◦Focus is on testing theory
◦Variables are well defined and measured with numbers
◦Variables are more likely to be “dependent” or “independent”
◦Researchers attempt to control for error and bias, they select a systematic sample, and attempt to objectively assess a situation.
◦Theories and hypotheses are tested in cause-effect order.

Q

Conceptual model

A

◦Made up of concepts and propositions

◦They represent ways of thinking about a problem or ways of representing how complex things work the way that they do.

◦Models may draw on a number of theories to help understand a particular problem in a certain setting or context.

◦Models are not always as specific as a theory.

72
Q

What is nursing science?

A

Is an applied science that looks at system of relationships of human responses that traverse biological, behavioral, social, cultural, and spiritual domains. Draws from synthesized from pure, natural, and human sciences, including physiology, human health, and biology.

73
Q

Epistemology

A

studies way of knowing or acquiring knowledge. Draws on traditional ideas that can be verified through observation and proved by hypothesis testing.

74
Q

Methodology

A

-means of acquiring knowledge

75
Q

Empirics

A

the science of nursing. Engages in seeking and generating explanations that are systematic and controlled by factual evidence.

76
Q

Esthetics

A

the art of nursing. Relies on perception. Incorporates empathy and understanding. Creates values and meaning to account for variables that cannot be quantitatively formulated.

77
Q

Ethics

A

moral knowledge in nursing. Based on obligation to service and respect for human life. Rational and deliberate examination and evaluation of what is good, valuable, and desirable as goals, motives, or characteristics.

Q

Differentiate a career/occupation from a profession

A

An occupation is a job or career whereas a profession is a learned vocation or occupation that has status of superiority and precedence within a division of work. Occupations require widely varying levels of training or education, varying levels of skill, and widely variable defined knowledge bases. Professions are occupations, but not all occupations are professions.

80
Q

What is the basis/classification of nursing science?

A

The substantive, discipline specific knowledge that focuses on the human universe health process articulated in the nursing frameworks and theories. Nursing science recognizes the relationships of human responses in health and illness and address biologic, behavioral, social, and cultural domains. The goal of nursing science is to represent the nature of nursing to understand it, to explain it, and to use it for the benefit of humankind. Gives direction to the future generation of substantive nursing knowledge and it is nursing science that provides the knowledge for all aspects of nursing.

81
Q

Why is nursing considered a human science?

A

Because the discipline has examined issues related to behavior and culture, as well biology and physiology, and sought to recognize associations among factors that suggest explanatory variables for human health and illness. Human science created knew knowledge to provide understanding and interpretation of phenomena.

82
Q

What are the stages of development of nursing theory and philosophy?

A 
Silent knowledge
Received knowledge
Subjective knowledge
Procedural knowledge
Constructed knowledge
Integrated knowledge
83
Q

How can concepts be measured

A

Concepts can be concrete or abstract, variable (concrete) or non variable (discrete), and operationally or theoretically.
Concrete have simple, directly observable empirical referents that can be seen, felt, or heard (chair, the color red, jazz music). Abstract concepts are not clearly observable directly or indirectly (art, social support, personality, role).

84
Q

Variable

A

describe some dimensions of the phenomena. Permit classification of dimension or graduation of phenomena on a continuum, (BP, pain, quality of life, health promoting behaviors, and cultural identity)

85
Q

Non variable are discrete concept

A

identifies categories or classes of characteristics (gender, ethnic background, religion). Can be answered yes or no.

86
Q

theoretical definition

A

gives meaning to a term in context of a theory and permits any reader to assess the validity of the definition.

87
Q

Operational definition

A

tells how the concept is linked to concrete situations and describes a set of procedures that will be performed to assessing a value for the concept. It permits the concept to be measured and allow hypotheses to be tested. Form the bridge between the theory and the empirical world.

88
Q

Describe the relationship[s] among theory, research, and practice

A

In applied nursing practice it is based on the theories that are validated through research. Research validated and modifies theory. Theory guides practice. Research is key to the development of a discipline
