Question 1

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?

Accepted Answer

This finding will impact the formulation of the problem because the researcher needs to refine and narrow down the scope to fit within the identified time frame.

Question 2

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?

Accepted Answer

The dependent variable is the variable being measured or observed in a study, in this case, the recovery of lower extremity function. Active, range of motion, and Guillain-Barré syndrome are all independent variables that may have an effect on the dependent variable.

Question 3

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?

Accepted Answer

Content validity is the extent to which a measurement tool adequately covers all facets of the concept being measured. If an instrument has been approved by a panel of judges, then it likely has been reviewed for its content validity. Therefore, the nurse can interpret the validity of the instrument used in the study as being valid for content.

Question 4

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?

Accepted Answer

The sentence is a statement of the hypothesis for the study, making a specific prediction about the expected results of the intervention.

Question 5

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?

Accepted Answer

Subjects can only be recruited for data collection after authorization is granted by the institutional review board. Before the IRB grants authorization, the researcher cannot begin any aspects of the study, including recruitment of subjects. Options A and D are incorrect because they do not address the IRB's role in approving the study, and option B is incorrect because recruitment cannot occur before IRB approval.

Question 6

The nurse researcher plans to use systematic random sampling for a quantitative study.How will the nurse implement this approach?
 Select all that apply.

Accepted Answer

The answer of The nurse researcher plans to use systematic...

Question 7

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?

Accepted Answer

The nurse is calculating the mean, which is the sum of all scores divided by the sample size. The mean is a measure of central tendency that represents the average of the data.

Question 8

The nurse researcher is determining the variance of the data collected during a quantitative study.What will this calculation explain?

Accepted Answer

The answer of The nurse researcher is determining the variance...

Question 9

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?

Accepted Answer

The implications section of a research report discusses the practical applications of the study's findings and is where the nurse would find information on how to implement the results into practice. The research question and hypothesis sections describe the study's objectives and proposed relationships, while generalizability pertains to the study's external validity.

Question 10

The nurse researcher is planning a quantitative study.What does the nurse identify as an advantage of using this research approach?

Accepted Answer

One advantage of using a quantitative research approach is that it is objective, meaning that it focuses on measurable data and avoids personal biases or opinions of the researcher.

Question 11

The nurse is reviewing a quantitative research study and is having difficulty identifying the theoretic framework.What does this finding indicate to the nurse?

Accepted Answer

The absence of a clear theoretic framework in a quantitative research study can make it challenging to understand how the research findings fit into existing knowledge or how they can be applied in practice. This is because the theoretic framework helps to guide the research questions, methodology, and interpretation of results, providing a context for understanding the significance of the study's findings. Without this framework, integrating the results into practice may be difficult due to a lack of understanding of how the findings relate to existing theories or concepts.

Question 12

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?

Accepted Answer

A questionnaire is a common instrument used to collect quantitative data by asking participants to respond to a set of standardized questions. It can be used to gather information about knowledge, attitudes, beliefs and behaviors related to a specific research question. In this case, the nurse plans to collect data about knowledge and feelings about a clinical intervention, which makes a questionnaire an appropriate choice. Checklist, categorized list, and rating scale are also types of quantitative instruments, but they may not be the best fit for this particular research question.

Question 13

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?

Accepted Answer

Non-probability sampling is a method in which not every element in the population has an equal chance of being selected for the sample. Therefore, findings from this type of sampling cannot be generalized to the population with any confidence.

Question 14

The nurse researcher has identified eligible participants for a quantitative study.Which actions would the nurse use to ensure an adequate sample size?
 Select all that apply.

Accepted Answer

The answer of The nurse researcher has identified eligible participants...

Question 15

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?

Accepted Answer

Placing data as a frequency distribution allows for the use of central tendency (mean, median, mode) and measures of spread (range, standard deviation), which can provide important information about the distribution of the data. It does not determine significance, fit into a larger picture, or explain unexpected findings.
