DNP 816- MODULE 1 EXAM UPDATED
QUESTIONS AND CORRECT ANSWERS.
Exploratory questions - ANS to get an idea, explore, do not give definitive answer, "what if"
descriptive questions - ANS characterize, explain, describe, "what is" "how"
relational questions - ANS relationship between variables, "does" "is"
experimental research design - ANS used to determine the causes of behavior that can
explain why it occurs
quasi-experimental design - ANS used to identify the relationship between preexisting
variables
nonexperimental design - ANS used to describe variables and predict the relationship
an experiment includes three key elements that allow cause-and-effect conclusions and control
- ANS randomization, manipulation, comparison/control group
experimental research strength - ANS cause and effect, strong evidence, 3 controls

, experimental research limitation - ANS behavior might not be the same in natural
environment
hard to assure adherence to protocols
lack framework
time and money
hawthorne effect
Randomization - ANS each individual is given an equal, random chance of selection
cofounding variable - ANS unanticipated variable that could be causing a change in measured
variables
independent variable - ANS variable that is manipulated, "presumed cause"
dependent variable - ANS the variable that changes, "presumed effect"
basic random assignment posttest - ANS 1. control group- no deep breathing
2. treatment- deep breathing
3. measure anxiety
basic random pretest-posttest - ANS 1. measure anxiety 3 hr before mri
2. control- no deep breathing
3. treatment- deep breathing
4. measure anxiety 30 min before mri
factorial design - ANS manipulate 2 or more variables
random assignment
treatment groups
looks at effects and interaction
