Question 1
Type: MCSA
The nurse researcher is planning a quantitative study. What does the nurse identify as an advantage of using this research approach?
1. The process is objective.
2. The number of phases is variable.
3. Mathematic calculations are minimal.
4. Use of the findings in nursing practice can be omitted.
Correct Answer: 1
Rationale 1: In quantitative research, the process is objective. (See page 77)
Rationale 2: There are five complete phases within quantitative research. Some phases may overlap but they form a generalized pattern. (See page 77)
Rationale 3: The purpose of quantitative research is to collect and convert data into numerical form. Mathematic calculations will be used throughout the phases. (See page 77)
Rationale 4: The purpose of research in nursing is to be able to apply the findings to nursing practice. This part of the research cannot be omitted. (See page 77)

Question 2
Type: MCSA
While conceptualizing the problem of a quantitative study, the nurse researcher learns that the problem scope may not be thoroughly studied in the identified time frame. This finding will impact which aspect of the conceptualization process?
1. Review the literature.
2. Formulate the problem.
3. Develop a framework.
4. Formulate the variables.
Correct Answer: 2
Rationale 1: The literature review is a search of information that is relevant to the identified problem area. Consideration of resources, including problem scope, is included when formulating the problem. (See page 80)
Rationale 2: One aspect when formulating the problem is considering the resources needed for the study. When considering time, the researcher must address if the scope of the chosen problem is narrow enough to be studied in the time allotted. (See page 80)
Rationale 3: When developing a framework, the theory, theories, or conceptual framework for the study are identified. Consideration of resources, including problem scope, is included when formulating the problem. (See page 80)
Rationale 4: When formulating the variables, the attributes or concepts that will change when conducting the study or as findings from the study are identified. Consideration of resources, including problem scope, is included when formulating the problem. (See page 80)

Question 3
Type: MCSA
The nurse is reviewing a quantitative research study and is having difficulty identifying the theoretic framework. What does this finding indicate to the nurse?
1. The study is founded on research problems.
2. The study refutes any theoretic explanations.
3. The research results will be difficult to integrate into practice.
4. The links between concepts have yet to be meaningfully tested.
Correct Answer: 3
Rationale 1: A quantitative study that is founded on research problems would have a clearly identified theoretic framework. (See page 82)
Rationale 2: A quantitative study would need to have a clearly identified theoretic framework in order for the study to refute theoretic explanations. (See page 82)
Rationale 3: The lack of a clear framework within a quantitative research study makes it harder to integrate research results back into the current body of knowledge. (See page 82)
Rationale 4: A conceptual framework is a less formally organized structure. In this structure, concepts have yet to be meaningfully tested. (See page 82)

Question 4
Type: MCSA
The nurse reads the following statement in a quantitative study: “The impact of active-range-of-motion exercises on the recovery of lower extremity function in patients diagnosed with Guillain-Barré syndrome.” What is the dependent variable?
1. Active
2. Range of motion
3. Guillain-Barré syndrome
4. Lower extremity function
Correct Answer: 4
Rationale 1: Active is used to describe the type of range of motion exercises. (See page 83)
Rationale 2: Range of motion is the variable that is used to explain or predict the change. This phrase is the independent variable. (See page 83)
Rationale 3: Guillain-Barré syndrome is identifying the population of study. (See page 83)
Rationale 4: Lower extremity function is the outcome variable or the dependent variable. (See page 83)

Question 5
Type: MCSA
The following sentence appears at the beginning of a quantitative research study: “Male patients with osteoarthritis will demonstrate an improvement in pain level and function after participating in structured muscle-strengthening exercise sessions for 30 minutes three times a week.” What does the nurse identify this sentence as being in the research study?
1. Hypothesis
2. Research questions
3. Conceptual definition
4. Operational definition
Correct Answer: 1
Rationale 1: The hypothesis makes a prediction about the expected outcomes of the study. It is an educated guess about the relationship or differences among variables. (See page 84)
Rationale 2: Research questions identify the variables under study and ask how those variables may be described or what relationship exists between them. This statement is not a research question. (See page 84)
Rationale 3: A conceptual definition is derived from a review of the literature and is used to place the meaning of the variable in the context of the research study. This statement is not a conceptual definition. (See page 84)
Rationale 4: An operational definition spells out how the variable will be measured or manipulated in a research study. This statement is not an operational definition. (See page 84)

Question 6
Type: MCMA
The nurse researcher plans to use systematic random sampling for a quantitative study. How will the nurse implement this approach?
Standard Text: Select all that apply.
1. Create a non-alphabetical list.
2. Select every kth participant on a random list.
3. Assign numbers to the sample using a lottery.
4. Subdivide the list and assign numbers using a lottery.
5. Identify populations and identify participants from within the populations.
Correct Answer: 1,2
Rationale 1: When using a systematic random sampling approach, the list of participants cannot be alphabetized. (See page 89)
Rationale 2: When using a systematic random sampling approach, every kth participant is selected. (See page 89)
Rationale 3: Assigning numbers to the sample using a lottery is the approach used for simple random sampling. (See page 89)
Rationale 4: Subdividing the list and assigning numbers using a lottery is the approach used for a stratified random sample. (See page 89)
Rationale 5: Identifying populations and identifying participants from within the populations is the approach used for cluster or multistage sampling. (See page 89)

Question 7
Type: MCSA
The results of a quantitative research study include a statement that the study used a non-probability population sample. How will the nurse interpret this statement?
1. Sample is a mathematical representation of the population.
2. The results of the study can be generalized to the population.
3. The findings cannot be generalized to the population with any confidence.
4. Each element in the population has an independent chance of being in the sample.
Correct Answer: 3
Rationale 1: The sample being a mathematical representation of the population is a characteristic of a probability sample. (See page 89)
Rationale 2: The results of the study being generalized to the population are a characteristic of a probability sample. (See page 89)
Rationale 3: The findings not being generalized to the population with any confidence is a characteristic of non-probability population sampling. (See page 89)
Rationale 4: Each element of the population having an independent chance of being in the sample is a characteristic of a probability sample. (See page 89)

Question 8
Type: MCSA
The nurse is planning a quantitative research study where the participants will be asked to report knowledge and feelings about a clinical intervention. Which type of instrument will the nurse utilize to collect this data?
1. Checklist
2. Rating scale
3. Categorized list
4. Questionnaire
Correct Answer: 4
Rationale 1: A checklist would be used if the researcher is available to note the frequency of a behavior. (See page 92)
Rationale 2: A rating scale would be used to note the intensity of a behavior. (See page 92)
Rationale 3: A categorized list would be used to classify a behavior. (See page 92)
Rationale 4: A questionnaire is used to self-report knowledge, feelings, attitudes, or beliefs and is the most widely used form of data collection in nursing research. (See page 92)

Question 9
Type: MCSA
The content of a quantitative research study identified that the instrument used to collect data was approved by a panel of judges. How will the nurse interpret the validity of the instrument used in the study?
1. It is valid for content.
2. It is valid for criterion.
3. It is valid for construct.
4. It is valid for equivalence.
Correct Answer: 1
Rationale 1: Content validity is assessed by using a logical evaluation of whether the instrument reflects the content for a particular subject. A panel of judges may be asked to evaluate the instrument. This is the weakest form of validity. (See page 93)
Rationale 2: Statistical measures are used to assess criterion validity. Instrument scores are correlated to scores on measures of some external criterion. (See page 93)
Rationale 3: Construct validity is assessed using a combination of logical and statistical measures. This is the strongest form of validity. (See page 93)
Rationale 4: Equivalence is used when determining the reliability of an instrument. (See page 93)

Question 10
Type: MCMA
The nurse researcher has identified eligible participants for a quantitative study. Which actions would the nurse use to ensure an adequate sample size?
Standard Text: Select all that apply.
1. Complete a screening form.
2. Offer an incentive to participating.
3. Provide an informed consent form.
4. Explain the benefits of participation.
5. Identify the convenience of participating.
Correct Answer: 2,4,5
Rationale 1: A screening form is used to find potential participants and would be done during the identification of eligible participants’ process. (See page 96)
Rationale 2: Some researchers have found that the use of incentives is helpful to encourage individuals to participate in a research study. (See page 96)
Rationale 3: The informed consent form is provided after the individuals agree to participate in the study. (See page 96)
Rationale 4: One effective recruitment strategy is delineating the benefits of participating in the study. (See page 96)
Rationale 5: The researcher should strive to make participation easy and convenient. (See page 96)

Question 11
Type: MCSA
The nurse researcher is designing the implementation phase of a quantitative study. At which point will the nurse be able to recruit subjects for data collection?
1. Upon submission of the research study to the institutional review board
2. Before the institutional review board reviews the research proposal
3. When authorization is granted by the institutional review board
4. After the data collection tool is tested for reliability and validity
Correct Answer: 3
Rationale 1: The nurse will not be able to recruit subjects for data collection until authorization for the study has been granted by the institutional review board and not when the proposal is submitted to them for approval. (See page 95)
Rationale 2: The nurse will not be able to recruit subjects for data collection before the institutional review board reviews the research proposal. Authorization from the board must occur first. (See page 95)
Rationale 3: When authorization is granted by the institutional review board the nurse will be able to recruit subjects for data collection. (See page 95)
Rationale 4: The nurse cannot recruit subjects for data collection until the institutional review board approves the study. The data collection tool does not influence when this process will occur. (See page 95)

Question 12
Type: MCSA
During the analysis of data collected during a quantitative study, the nurse places some data as a frequency distribution. What purpose will this type of data display serve?
1. Identifies if the findings were significant or not
2. Determines if the statistics fit into the larger picture
3. Helps to explain why the findings were unexpected
4. Allow the use of central tendency and measures of spread
Correct Answer: 4
Rationale 1: The identification of the findings as being significant or not occurs when the findings are presented. (See page 99)
Rationale 2: Determining if the statistics fit into the larger picture occurs when the findings are presented. (See page 99)
Rationale 3: Helping to explain unexpected findings occurs when the findings are presented. (See page 99)

1. The characteristic clusters of data in a distribution
2. The spread of the data on the frequency distribution
3. The average distance of spread in a frequency distribution
4. The average area of spread under the frequency distribution curve
Correct Answer: 4
Rationale 1: The characteristic clusters of data in a distribution describe the measure of central tendency. (See page 100)
Rationale 2: The spread of the data on the frequency distribution is the range. (See page 100)
Rationale 3: The average distance of spread in a frequency distribution is the standard deviation. (See page 100)
Rationale 4: The variance is the average area of spread under the frequency distribution curve. (See page 100)

Question 14
Type: MCSA
When analyzing the data collected during a quantitative research study, the nurse adds up all of the scores obtained from the sample and divides it by the number of scores added together. What measure of central tendency is the nurse calculating?
1. Mean
2. Mode
3. Range
4. Median
Correct Answer: 1
Rationale 1: The mean is the average of all the values for a particular characteristic and is calculated by adding up all the scores and dividing by the number of scores added together. (See page 100)
Rationale 2: The mode is the numerical value that occurs most often for a particular characteristic. (See page 100)
Rationale 3: The range is calculated by subtracting the lowest value from the highest value. (See page 100)
Rationale 4: The median is the middle value in a frequency distribution. (See page 100)

Question 15
Type: MCSA
The nurse is reading the results of a quantitative study for ways to implement the findings into practice. Which area of the report would the nurse find this information?
1. Research question
2. Generalizability
3. Implications
4. Hypothesis
Correct Answer: 3
Rationale 1: The research question identifies the variables under study and does not provide ways to implement the findings into practice. (See page 103)
Rationale 2: Generalizability refers to the ability to apply study results from the sample to the population. It does not provide ways to implement the findings into practice. (See page 103)
Rationale 3: An implication is an inference drawn about the study results that determines what the study means in terms of practice and research. This is where information about implementing the findings into practice would appear. (See page 103)
Rationale 4: The hypothesis makes a prediction about the expected outcomes of the study. It does not include ways to implement the findings into practice. (See page 103)
