Questions and Answers.
A study was done to investigate factors associated with UTI among hospitalized patients. An
investigator identified 100 hospitalized patients with urinary tract infection (UTI) as diagnosed
by urine cultures. She matched this group (on age, gender and diagnosis) with another group of
100 patients in the same hospital that did not have a UTI. It was determined which of these
patients had a Foley catheter during their hospitalization. It was found that 78 of the patients in
the UTI group had Foley catheters compared to 31 of the subjects in the non-UTI group. This
type of study design is called a: - Answer Case-control study
Nurse researchers develop data collection protocols to ensure accurate, valid, and meaningful
data. What is a data collection protocol? - Answer Spells out procedures to be used in data
collection
The independent variable in the research question "What is the effect of noise levels on
postoperative pain or blood pressure fluctuations in ICU patients?" is: - Answer Noise levels
What are the building blocks of theory? - Answer Concepts
What is a hallmark of the scientific method? - Answer Systematic
What is included in the methods section of a study? - Answer Strategies used to address the
problem
What is the independent variable in the hypothesis "In the ICU, Baccalaureate degree prepared
nurses will practice more rehabilitative nursing measures on a patient than will associate degree
prepared nurses"? - Answer Type of educational background of nurses
What is the most effective method of controlling extraneous variables? - Answer
Randomization
When is a study internally valid? - Answer Alternative explanations of the results can be
ruled out
Where are registered nurses most likely to find research results? - Answer Journal articles
To study the effects of a new treatment compared to the current standard of care, the main
advantage of a randomized controlled trial over a cohort study is: - Answer There would be
better prevention of confounding
