In health sciences it is unlikely that researchers will be able to establish
absolute causality. Therefore, most nursing research studies must deal with
relative cause and probabilities of a cause leading to an effect. Which of the
following statements about probability is true? - CORRECT ANSWER -
The researcher investigates the likelihood that an effect will occur under
specific circumstances
Manipulation is a term used in research to mean - CORRECT ANSWER -
The ability to determine the various treatments given to groups in quasi-
experimental and experimental studies
Bias is a term used to indicate that data in a study are being distorted or
slanted away from reality by some influencing factor. Which of the
following statements about bias in research s true? - CORRECT ANSWER
-Preconceived ideas about what the findings of a study may be could lead to
bias in interpreting data
Controlling the treatment is one of the elements of a good design. Which of
the following statements about this element is true? - CORRECT ANSWER
-Controlling the treatment is enhanced with a clear description of all steps
of the treatment
,the design for a study to gain more information about characteristics within
a particular field of a study should be - CORRECT ANSWER -Descriptive
Case study designs can involve in-depth study of - CORRECT ANSWER -A
single institution, Small groups of subjects, A family
Which of the following can be achieved using a correlational design? -
CORRECT ANSWER -Testing of relationships proposed in a theoretical
proposition
Which of the following statements about quasi-experimental designs is
true? - CORRECT ANSWER -They are an alternative for establishing
causality when an experimental study might not be ethical or feasible
Which of the following statements about replication studies is true? -
CORRECT ANSWER -Replication studies extent knowledge even if they do
not confirm previous study findings
Which of the following elements are required in an experimental design? -
CORRECT ANSWER -Random assignment of subjects to groups, control
of variance in sampling, and carefully defined variables
A randomized clinical trial is used to study what kind of effect? - CORRECT
ANSWER -Treatment outcome
,The most critical goal of proper research design is - CORRECT ANSWER -
Consistency
Other than data related to the concepts being measured to address the
research objectives, questions, or hypotheses, what data can be controlled
in the data collection process? - CORRECT ANSWER -Demographic data
such as age, gender, and the like, Information related to the diagnosis (For
clinical studies), and Cormorbid conditions or problems in addition to the
admitting diagnosis
Several problems can occur during data collection. Which f the following is
a researcher-related problem? - CORRECT ANSWER -Bias
Comparison groups are a feature of which of the following research
designs? - CORRECT ANSWER -Quas-experimental study
The funding agency that focuses most on outcomes research is - CORRECT
ANSWER -The agency of Healthcare Policy and Research
The sampling method most desired for outcome studies is - CORRECT
ANSWER -Convenience sampling using large heterogeneous samples
The process of describing clinical problems, identifying possible courses
action, assessing the probability of outcomes, and calculating a optimal
course of action is referred to as - CORRECT ANSWER -Clinical decision
analysis
, a unique characteristic of prospective cohort studies is that - CORRECT
ANSWER -Data are collected from subjects who are at risk for, but do not
currently have the problem identified
Which of the following statements about outcome variables is true? -
CORRECT ANSWER -Available measuring instruments must be sensitive
enough to detect changes over time
Outcomes in nursing research are considered time dependent for which of
the following reasons? - CORRECT ANSWER -Some findings may not be
apparent for a long time, The results may be only temporary, and Outcomes
in some instances are immediately seen
According to sampling theory, findings can be generalized to - CORRECT
ANSWER -the target population
the definition of target population is - CORRECT ANSWER -A list of all
members of the population
the definition of a set of sampling criteria is - CORRECT ANSWER -A list
of the characteristics essential to be a member of the target population
The term representativeness means that - CORRECT ANSWER -the
sample must be like the population in as many ways as possible
