Week 3 Quiz Flashcards
In a non-experimental study all of the following questions would be addressed in designing the study except:
What is the nature of the comparisons being made?
Where will the study take place?
How many times will the data be collected?
Over how long a period while the intervention be administered?
D
Which of the following hypotheses are indicative of an experimental research design?
The incidence of urinary tract infections will not differ between patients with or without Foley catheters.
Patients with Foley catheters describe experiences of burning and the need to void
Frequent irrigation of Foley catheters is associated with urinary tract infections
Frequent irrigation of Foley catheters will be positively related to urinary tract infections
A
What is the purpose of a longitudinal study?
To describe the effect of time on a process by simultaneous examination of various subjects in different stages of that process
To examine change in variables of interest over time by re-measuring the variables in the same subjects
To demonstrate that time is the cause of several affects
To describe the effect of time on a variable
B
What feature of a non-equivalent control group design makes it a quasi experimental rather than a pre-experimental?
Lack of randomization
Use of a post test
Use of a pretest
Manipulation of the independent variable
C
What is meant by the term blinding in a randomized controlled trial?
Refers to the uncertainty regarding whether a new treatment is going to be affective for the trial participant
The results of the study totally disagree with previously published studies, necessitating reevaluation of the data
The subjects and or investigators do not know which treatment group the subject is in
Research begins with the no hypothesis, and conclusions are based totally on statistical analysis of the data without any preconceived ideas
C
Which of the following studies represent retrospective research?
A researcher spend a week in the online library, performing a literature review, gathering multiple journal articles
On June 30 each year the nurse manager collects data for the entire fiscal year, comparing sickleave per nurse per month in February with sickleave per nurse per month in May.
And animal research or administer standard multivitamins to one group of rabbits and double doses to other groups of rabbits measuring linear growth
A university professor follows 30 subjects, collecting data each semester for four years, related to grade point average.
B

B
Nurses are conducting a research study investigating the effects of chlorhexidine bathing prior to open heart surgery on post operative infection rates. This type of research is considered:
Translational research
Outcomes research
Survey research
Evaluation research
B
Research studies that do test specific relationship between variables are called
Descriptive studies
Experimental research
CorrelationAl Studies
Quasi experimental research
A
The designs principally used in outcomes research are derived from which of the following disciplines?
Medicine
Statistics and economics
Ethnography
Epidemeology
D
Which statement is true about quasi experimental design?
They may be used to establish correlations between variables when an experimental study is not feasible
They are inferior to experimental designs in most aspects
They are an alternative for establishing causality when an experimental study might not be ethical or feasible
Threats to internal validity cannot be adequately controlled without severely threatening external validity in the studies
C
Which of the following approaches could involve the use of data gathered in previous study to test a new hypothesis
Secondary analysis
Survey research
Needs assessment
Meta-analysis
A
A researcher is investigating the prevalence of breast cancer among women who have never been pregnant. Dad is collected on one day via phone calls to patients with this known history, who are patients of this woman’s health group. This type of research is classified as:
Clinical trial
Cross-sectional
Comparative effectiveness
Delphi study
B
One way to determine if there is a cause-and-effect relationship between two variables is to do
Descriptive Study
Experimental research
Exploratory research
Correlational study
B
True experimental designs have three identifying properties:
Generalizability, selectivity, and randomization
Manipulation, control, and randomization
Attrition, reactivity, and effects of testing
Effects of selection, manipulation, and bias
B
