Standard Text: Select all that apply.

A)Control
B)Time series
C)Manipulation
D)Random assignment
E)Static group comparison

Answer 1

Control

A)Post hoc
B)Predictive
C)Static group comparison
D)Randomized controlled trial

Answer 2

Post hoc

Question 3

B)Success of diet management and exercise on weight reduction and maintenance over 20 years
C)Number of patients who take beta blockers as prescribed after having an acute myocardial infarction
D)Effects of nuclear energy power plant accidents on the number of new cases of breast cancer in a community

Answer 3

Success of diet management and exercise on weight reduction and maintenance over 20 years

Question 4

A non-experimental design is being used for a quantitative study.What will occur during this study?

A)A concept will be manipulated.
B)A concept will not be manipulated.
C)Data will be collected over several years.
D)A large sample size from multiple sites and settings will be used.

Question 5

A quasi-experimental quantitative study is planned,using a non-equivalent control group.What will occur with the groups during this study?
Standard Text: Select all that apply.

A)The control group will receive nothing.
B)The experimental group will receive a treatment.
C)Participants are randomly assigned to the groups.
D)A single group is used for the duration of the study.
E)Both groups will have the dependent variable measured.

Question 6

The nurse researcher is planning to use a randomized control trial for the design of a quantitative study.What will occur when this design is used?

A)Data will be collected as it unfolds.
B)The researcher will serve as an observer.
C)A large sample will be used from multiple sites and settings.
D)Data will be collected on events that occurred before the study.

Question 7

The nurse researcher is planning a quantitative study using a non-experimental design.What is an advantage of using this type of design in a study?

A)A specific treatment or intervention can be used.
B)It determines a relationship between variables that already exists.
C)A treatment can be provided on events that have already occurred.
D)It provides evidence to promote a change in a specific nursing intervention.

Question 8

A quantitative research project is being designed in order to answer a clinical problem.What is the motivation behind this study?

A)Basic
B)Applied
C)Descriptive
D)Explanatory

Question 9

After reading the results of a true experimental design quantitative study,the nurse decides that additional studies are needed before implementing a change to address a clinical problem.What did the nurse determine after reading the results of the study?

A)The results could only be applied to a select group of patients.
B)Interventions were highly tested and would produce a change.
C)The groups that were studied were not randomized.
D)Only the experimental group received a treatment.

Question 10

The nurse is designing a quantitative research study.What is the purpose of this type of study in nursing?

A)Determine how patients feel about prescribed treatments.
B)Answer questions about statistically measurable concepts.
C)Understand the nursing process in relation to the scientific method.
D)Identify interventions that are based upon the best evidence from research.

Question 11

Why would the nurse search for the results of a true experimental design quantitative study for recommendations to change a patient care intervention?

A)Produces the highest quality of evidence for nursing practice
B)Based upon the outcomes from a tightly studied group
C)Limits the number of variables that can be studied
D)Reduces the need to randomize samples

Question 12

An explanatory study is being designed to measure the outcomes when implementing a specific intervention during patient care.What are the characteristics of this type of quantitative study?
Standard Text: Select all that apply.

A)Searches for a specific cause and effect
B)Focuses on the prevalence of concepts
C)Explains why concepts are related
D)Explains how concepts are linked
E)Describes identified concepts

Question 13

The nurse wants to study a set of variables that have already occurred.Which type of research design would support this nurse's needs?

A)Pre-experimental
B)Non-experimental
C)True experimental
D)Quasi-experimental

Question 14

The nurse researcher was planning a quantitative study using a true experimental design.However,it changed to a pre-experimental design.Which characteristic would not be used in the pre-experimental design?

A)Two groups
B)Treatment applied
C)Random group assignments
D)Dependent variable measured

Question 15

The nurse researcher is planning a quantitative study to measure the results on several different variables.Why would a true experimental design approach not be appropriate for this study?

A)The amount of resources needed to conduct this study would be too great.
B)The process limits the number of variables that can be studied at one time.
C)The analysis of the data could not be interpreted for the nursing community.
D)The researcher would not be able to identify an appropriate measurement tool.
