5366 Principles of Research in Nursing |
Actual Q&A with Rationale (NURS5366
Module 4 Exam) | The University of Texas
at Arlington
1. Which characteristic is essential for a research design to be classified as a true
experimental design?
A. Randomization of subjects to groups
B. Manipulation of the dependent variable
C. Selection of a convenience sample
D. Use of a qualitative interview guide
Answer: A
Rationale: The Randomization of subjects to groups is a core requirement of a true
experimental design, along with control and manipulation. This process helps ensure that
any differences found between groups are due to the intervention rather than pre-existing
differences. Without random assignment, the study is classified as quasi-experimental or
non-experimental.
2. A nurse researcher is studying the lived experience of patients undergoing chemotherapy.
Which qualitative research tradition is most appropriate?
A. Phenomenology
,B. Ethnography
C. Grounded Theory
D. Historical Research
Answer: A
Rationale: Phenomenology is the research tradition specifically designed to explore the
essence of a lived experience. It seeks to understand how individuals perceive and describe
a specific phenomenon they have encountered. In this context, the researcher wants to
capture the personal and subjective reality of patients in chemotherapy.
3. Which threat to internal validity occurs when an external event happens during the study
that influences the dependent variable?
A. Maturation
B. Selection Bias
C. Testing Effects
D. History
Answer: D
Rationale: History refers to events that occur outside of the researcher’s control during
the course of a study that might affect the participants’ responses. For instance, a public
health campaign launching at the same time as a private smoking cessation study could
, skew the results. Researchers must monitor for these external influences to maintain the
integrity of their findings.
4. What is the primary purpose of using a quasi-experimental design in nursing research?
A. To examine causal relationships when randomization is not possible
B. To prove absolute causality in a laboratory setting
C. To describe the frequency of a certain disease in a population
D. To explore the cultural beliefs of a specific community
Answer: A
Rationale: To examine causal relationships when randomization is not possible is the
primary utility of quasi-experimental research. While it lacks the randomization of a true
experiment, it still involves the manipulation of an independent variable. This is often more
feasible in clinical nursing settings where random assignment may be unethical or
impractical.
5. In a study comparing the effectiveness of two different wound dressings, the wound
healing rate is which type of variable?
A. Independent Variable
B. Dependent Variable
C. Extraneous Variable
D. Conforming Variable
