ADVANCED NURSING RESEARCH (NUR
631) FINAL EXAM QUESTIONS AND
ANSWERS 100% VERIFIED BY
EXPERTS. 2026/2027
1. A researcher is designing a study to examine the effect of a new position protocol on the
incidence of pressure ulcers. In the PICOT format, what does the ‘T’ represent?
A. Timeframe
B. Theoretical framework
C. Treatment
D. Target population
Answer: A
Conceptual Explanation: In the PICOT acronym, T stands for Time, which refers to the
time it takes for the intervention to achieve an outcome or the duration of the study.
2. Which ethical principle from the Belmont Report is violated if a researcher excludes a
specific ethnic group from a study without clinical justification?
A. Beneficence
B. Respect for Persons
C. Justice
,D. Non-maleficence
Answer: C
Conceptual Explanation: Justice refers to the fair distribution of the burdens and benefits
of research. Excluding groups without justification violates this principle.
3. A study reports a p-value of 0.02. If the alpha level was set at 0.05, what is the correct
statistical conclusion?
A. Reject the null hypothesis
B. Fail to reject the null hypothesis
C. Accept the null hypothesis
D. The results are not statistically significant
Answer: A
Conceptual Explanation: Since the p-value (0.02) is less than the alpha level (0.05), the
researcher rejects the null hypothesis, indicating statistical significance.
4. In a study measuring the effect of a nurse-led education program on blood glucose levels,
what is the dependent variable?
A. Nurse-led education program
B. Blood glucose levels
C. Patient age
D. Type of insulin used
, Answer: B
Conceptual Explanation: The dependent variable is the outcome or effect being measured,
which in this case is the blood glucose levels.
5. What is the primary difference between a quasi-experimental design and a true
experimental design?
A. Random assignment of participants
B. Manipulation of the independent variable
C. Use of a control group
D. Collection of pre-test and post-test data
Answer: A
Conceptual Explanation: Quasi-experimental designs lack the random assignment of
participants to groups, which is a requirement for true experimental designs.
6. A researcher uses a process called ‘bracketing’ in a qualitative study. Which methodology is
most likely being used?
A. Grounded Theory
B. Ethnography
C. Historical Research
D. Phenomenology
Answer: D
