Question 1

"The purpose of this study was to determine the extent to which sex, age, height, and weight predict selected physiologic outcomes: namely, forced expiratory volume (FEV) in 1 second, hemoglobin concentration, food intake, serum glucose concentration, total serum cholesterol concentration, and cancer-related weight change (Brown et al., 1997)." In this study, the dependent variable is the physiologic outcomes.

Accepted Answer

The dependent variable is what the study aims to predict or measure, which in this case are the physiologic outcomes like FEV, hemoglobin concentration, etc.

Question 2

The best way to facilitate an effective search using an index is to know which key terms to use.

Accepted Answer

Knowing the right key terms helps in efficiently navigating and retrieving relevant information from an index.

Question 3

When credit is given for a new idea generated by challenging an old idea, it ethically builds nursing knowledge and helps others understand the evolution of that knowledge by honoring the prior research work.

Accepted Answer

Challenging old ideas with new ones while giving credit to previous research respects the contributions of past work and promotes the ethical advancement of nursing knowledge.

Question 4

Because internal and external validity were originally developed to evaluate cause-and-effect relationships, this makes them most relevant for experimental designs. However, validity should still be considered with all quantitative designs.

Accepted Answer

Internal and external validity are crucial for assessing cause-and-effect in experimental designs, but all quantitative research should consider validity to ensure accurate and generalizable results.

Question 5

Also known as prospective designs, cohort designs differ from longitudinal designs because cohort designs gather data about subjects at more than one point in time. They can be a panel design, crossover design, trend study, or follow-up study.

Accepted Answer

Cohort designs are a type of longitudinal design, as both involve gathering data over multiple points in time. The statement incorrectly suggests that cohort designs differ from longitudinal designs in this aspect.

Question 6

In epidemiology, the difference between sensitivity and specificity is that sensitivity is able to identify people with a disease by negative test results, and specificity determines by positive test results.

Accepted Answer

Sensitivity measures the ability to correctly identify those with the disease (true positive rate), while specificity measures the ability to correctly identify those without the disease (true negative rate).

Question 7

Examples of sources of data in qualitative research might include artifacts such as documents, photographs, and physical object, as well as in-depth interviews and direct observations.

Accepted Answer

Qualitative research often uses diverse data sources like documents, photographs, physical objects, interviews, and observations to gain a comprehensive understanding of the subject.

Question 8

One difference in the method of ethnographic qualitative research from the other types is that it uses the method of strategic sampling of a group of people who witnessed or participated in the phenomenon being studied.

Accepted Answer

Ethnographic research typically uses purposive or snowball sampling rather than strategic sampling, focusing on cultural immersion and observation of a group in their natural environment.

Question 9

One example of an ethical consideration of qualitative research that is generally not found in quantitative research is that that a participant may share personal information after developing a friendship-type relationship with the researcher, and the participant may not expect that information to be used as study data.

Accepted Answer

In qualitative research, the close interaction between researcher and participant can lead to personal disclosures that the participant may not intend to be part of the study, unlike in quantitative research where interactions are more structured and limited.

Question 10

In what way can evidence from disciplines other that of nursing compare to nursing evidence and be helpful to a nurse?

Accepted Answer

Theory-based non-nursing evidence can fill gaps in nursing knowledge and provide a foundation for developing new evidence, enhancing nursing practice.

Question 11

Which of the following is an example of an international code for ethical conduct by physicians conducting biomedical research which provides more specific guidelines than the Nuremburg Code?

Accepted Answer

The Declaration of Helsinki is an international code that provides ethical guidelines for physicians conducting biomedical research, offering more specific guidance than the Nuremberg Code.

Question 12

The statement, "There will be no difference in practice of nurses after completion of an EBP mentorship program as compared to before the mentorship program," is an example of which of the following?

Accepted Answer

The statement is a null hypothesis because it predicts that there will be no difference or effect as a result of the intervention (EBP mentorship program).

Question 13

When formulating hypotheses, how do conceptual definitions differ from operational definitions?

Accepted Answer

Conceptual definitions provide a theoretical meaning of a concept, similar to a dictionary definition, while operational definitions specify how the concept will be measured or observed empirically.

Question 14

A researcher hypothesizes that a new computer-based educational intervention program with a public health clinic will result in fewer unwanted pregnancies in low-income communities. Which of the subjects will be receiving the standard of care with a typical clinic-based education but not the intervention of the new computer-based education?

Accepted Answer

The control group receives the standard of care or typical treatment, which in this case is the clinic-based education, without the new computer-based intervention.

Question 15

Which of the following is an advantage of using a quasi-experimental design in nursing over an experimental design?

Accepted Answer

A quasi-experimental design provides beginning evidence of causality because it allows for the examination of relationships between variables when random assignment is not feasible, making it useful in real-world settings like nursing.

Question 16

Which of the following is an example of incidence in epidemiology?

Accepted Answer

Incidence refers to the number of new cases of a disease that occur in a specific population during a defined time period.

Question 17

Which of the following is a way phenomenology differs from the other four major types of qualitative research with regards to method?

Accepted Answer

Phenomenology uses purposive sampling, which involves selecting participants who have specific characteristics or experiences that are relevant to the research question.

Question 18

Why is it just as important that a nurse researcher have a good plan for collecting and managing data during a research study as it is essential to use a theoretical or conceptual model to ask the most important research questions?

Accepted Answer

Good data planning ensures that data is collected accurately and ethically, maintaining the integrity of the research study.

Question 19

A nurse researcher is creating a data collection plan for a study on tobacco usage among preteen girls. What are some things the researcher would do when creating a data collection plan?

Accepted Answer

The answer of A nurse researcher is creating a data...

Question 20

A nursing researcher has a well-designed study planned, but the study requires the use of a new data collection survey instrument to prevent possible error in measurement. Prior to starting the planned study, what additional type of study will the researcher need to perform to ensure the new instrument is tested?

Accepted Answer

The answer of A nursing researcher has a well-designed study...
