NURS 3300 FINAL EXAM QUESTIONS AND ANSWERS
What is the definition of theory? - CORRECT ANSWER✅✅A set of interrelated concepts that explains,
describes, or predicts phenomena.
How is nursing theory related to nursing research? - CORRECT ANSWER✅✅Theory guides the
development of research questions and hypotheses; research tests, supports, or refines theory.
How are nursing theory and practice related? - CORRECT ANSWER✅✅Theory informs practice, and
practice generates observations that refine theory.
What is the best way to read research critically? - CORRECT ANSWER✅✅Evaluate the study's purpose,
design, sample, methodology, validity, reliability, results, and limitations.
What is important to remember to be a knowledgeable consumer of nursing research? - CORRECT
ANSWER✅✅Assess the credibility, quality, and applicability of findings.
What library resource is most comprehensive for nursing literature? - CORRECT ANSWER✅✅CINAHL.
How do you identify independent and dependent variables? - CORRECT ANSWER✅✅Independent
variable: manipulated or categorized cause. Dependent variable: measured outcome.
What is a non-directional hypothesis? - CORRECT ANSWER✅✅Predicts a relationship exists but does
not specify direction.
What is a directional hypothesis? - CORRECT ANSWER✅✅Predicts the direction of the relationship
(such as increase or decrease).
What is an operational definition? - CORRECT ANSWER✅✅A specific explanation of how a variable will
be measured or observed.
, What does operationalization mean? - CORRECT ANSWER✅✅Turning abstract concepts into
measurable variables.
How does a theoretical framework differ from a conceptual framework? - CORRECT
ANSWER✅✅Theoretical framework uses a specific established theory; conceptual framework draws
from multiple theories or concepts.
Define control. - CORRECT ANSWER✅✅Keeping study conditions consistent to reduce bias.
Define randomization. - CORRECT ANSWER✅✅Assigning participants randomly to reduce selection
bias.
Define manipulation. - CORRECT ANSWER✅✅Deliberately changing the independent variable.
Why are control, randomization, and manipulation used? - CORRECT ANSWER✅✅They strengthen
internal validity and support causal inference.
What is the purpose of a research design? - CORRECT ANSWER✅✅Provides structure for conducting a
study and guiding procedures.
What benefit do tables and figures provide? - CORRECT ANSWER✅✅They summarize findings clearly
and highlight patterns.
What is reliability? - CORRECT ANSWER✅✅The consistency or stability of a measurement instrument.
What is validity? - CORRECT ANSWER✅✅The accuracy of a measurement instrument.
What is internal validity? - CORRECT ANSWER✅✅Confidence that the independent variable caused the
observed effect.
