NU 311 FINAL EXAM QUESTIONS & CORRECT
ANSWERS
What is evidence-based practice? And why is it important for nursing? -
ANSWER-Includes the integration of the best research evidence with clinical
expertise and considers patient needs and values
What does p < .05 mean? - ANSWER-A p-value less then 0.05 signifies statistical
significance. 95% chance of happening. Goes against null.
Experimental - cross-over, RCT, quasi - ANSWER-A randomized controlled trial
(RCT) is a study design that randomly assigns participants to groups to compare
different treatments or interventions:
Cross over: a research method where each participant receives multiple treatments
in different sequences over time, essentially acting as their own control by
experiencing all treatments, allowing for a direct comparison between them while
minimizing variability between individuals
Quasi: a research method where researchers study the impact of an intervention or
variable without randomly assigning participants to different groups, meaning they
cannot fully control who receives the treatment, making it distinct from a true
experiment;
Are correlation and qualitative experimental or Non-experimental? - ANSWER-
non-experimental
, What is phenomenology, grounded theory, and ethnography?( All qualitative
Research) - ANSWER-phenomenological- Based in psychology. The study of
lived experiences. Developed by Husserl and Heidegger. What is the essence of the
phenomena of caring?
grounded theory- Based in sociology. Seeks to understand and describe the key
psychological and structural processes that occur in a social setting
ethnographical- Based in anthropology. Researchers usually travel and do
"fieldwork" where they immerse themselves in another culture. By doing this they
"learn from" rather than study the culture under investigation
historical research-A narrative description of or analysis of events that occurred in
the remote or recent past. Past mistakes are examined to facilitate an understanding
of and an effective response to present situations
What is the Hawthorne effect? - ANSWER-when subjects of an experimental study
change or improve their behavior because it is being evaluated or studied.
What was the purpose of the Tuskegee Syphilis study? - ANSWER-a medical
experiment during which the U.S. Public Health Service (USPHS) studied the
natural history of syphilis in Black men without their knowledge or consent.
participants were told they were being treated because they had bad blood
What is internal validity? Face validity - ANSWER-the degree to which a research
study can confidently establish a causal relationship between variables, Whether
the instrument looks as though it is measuring the appropriate construct
What is external validity? - ANSWER-the extent to which the findings of a
research study can be generalized or applied to situations, people, and settings
