NURS 641 EXAM 2. COMPREHENSIVE EXAM
WITH ACTUAL QUESTIONS WITH CORRECT
VERIFIED ANSWERS. ALREADY GRADED A+
In a study of the effectiveness of two pain management
methods, what is the meaning of the conclusion that one
method produced a clinically significant lower pain level
than the other method?
A. The study was well-conducted.
B. The difference in outcome achieved by the more effective
method is large enough to make an important difference in
patient comfort.
C. Pain management is an important intervention.
D. The difference in outcomes achieved by the two groups
proves the underlying physiology being tested.
B. The difference in outcome achieved by the more effective
method is large enough to make an important difference in
patient comfort.
Which of the following results from a sample size that is too
small?
A. Lack of control over extraneous variables
B. A weak intervention
C. Limits to random sampling
,D. Low power to detect a difference in the outcomes of two
groups
D. Low power to detect a difference in the outcomes of two
groups
What is the relationship between clinical significance and
statistical significance?
A. Statistical significance determines clinical significance
B. Both can be significant, both can be nonsignificant, or
one can be significant and the other nonsignificant
C. If one is significant, the other is significant
D. Clinical significance determines the reliability of
statistical significance
B. Both can be significant, both can be nonsignificant, or
one can be significant and the other nonsignificant
Inconsistent delivery of either or both of the treatments has
what effect on the results of the study?
A. It could result in erroneous study conclusions
B. None, if the researcher corrects the inconsistency before
the end of the study
C. It could affect the inter-rater reliability of the outcome
D. It could cause the study participants to be dissatisfied
with their involvement in the study
, A. It could result in erroneous study conclusions
Why is a study categorized as quasi-experimental (as
opposed to being called experimental study)?
A. Because the researcher does not have a PhD
B. Because the intervention and/or setting was not tightly
controlled
C. Becuase the intervention was only partially tested
D. Because it was not possible to recruit participants from
the population of interest
B. Because the intervention and/or setting was not tightly
controlled
What type of quantitative research design looks for cause
and effect between an intervention and an outcome
variable?
A. Case-control design
B. Correlational design
C. Experimental design
D. Retrospective design
C. Experimental design
