5366 Principles of Research in Nursing |
Actual Q&A with Rationale (NURS5366
Module 2 Exam) | The University of Texas
at Arlington
1. When identifying a potential research problem, which factor most significantly determines
the feasibility of a study?
A. The researcher’s personal interest in the topic
B. Availability of subjects and resources
C. The complexity of the statistical software required
D. The length of the final research report
Answer: B
Rationale: The correct answer is Availability of subjects and resources because feasibility
involves practical considerations such as time, money, and access to participants. A
research problem may be significant but impossible to study if there is no access to the
target population. Without sufficient resources and subjects, the study cannot move
forward to the data collection phase.
2. A nurse researcher is examining the effect of a new wound care protocol on healing time.
In this study, what is the independent variable?
A. The wound care protocol
,B. The rate of healing
C. The age of the patients
D. The size of the wound
Answer: A
Rationale: The correct answer is The wound care protocol because it is the intervention or
treatment being manipulated. The independent variable is the presumed cause in a cause-
and-effect relationship. Researchers observe how changes in this variable influence the
outcome, which is the dependent variable.
3. Which type of hypothesis states that there is no relationship between the independent and
dependent variables?
A. Directional hypothesis
B. Null hypothesis
C. Research hypothesis
D. Non-directional hypothesis
Answer: B
Rationale: The correct answer is Null hypothesis as it represents a statement of no
difference or no relationship between variables. It is primarily used for statistical testing to
determine the probability that findings occurred by chance. If the researcher finds a
significant relationship, they reject the Null hypothesis in favor of the research hypothesis.
, 4. The nurse researcher reads a report of a study conducted by the original investigator. This
is an example of which type of source?
A. Tertiary source
B. Secondary source
C. Primary source
D. Systematic review
Answer: C
Rationale: The correct answer is Primary source because it is the original research report
written by the person who conducted the study. Primary sources provide the most direct
evidence of the research findings and methodology. In contrast, secondary sources
summarize or interpret the work of others rather than presenting new data.
5. In a research study, how a variable will be measured or manipulated is referred to as the:
A. Operational definition
B. Conceptual definition
C. Theoretical framework
D. Research design
Answer: A
Rationale: The correct answer is Operational definition because it specifies the exact
procedures and instruments used to observe or measure a variable. This allows other
