HESI Nursing Research Exam

Correct answer: B. Procedure section

Explanation of the correct answer:

B. Procedure section

The procedure section of a qualitative research study typically outlines how the study was conducted, including data collection, participant interactions, and ethical considerations. It is the most appropriate place to find information regarding how the study addressed legal-ethical issues such as informed consent, confidentiality, voluntary participation, and approval by an Institutional Review Board (IRB). This section ensures transparency about how the research protected the rights and well-being of participants.

Why the other options are incorrect:

A. Discussion section

The discussion section interprets the findings of the study and places them in the context of existing literature. While ethical issues might be mentioned here if they influenced results, this is not the primary location for detailed legal-ethical procedures.

C. Design section

The design section explains the type and structure of the study (e.g., phenomenological, grounded theory), but it focuses more on methodological approach than on ethical safeguards.

D. Sample section

The sample section describes the participants, selection criteria, and demographics. While it may include inclusion/exclusion criteria, it does not usually discuss legal-ethical considerations in detail.

Summary:

The procedure section is the most appropriate place to locate legal-ethical issues in a qualitative research study. This section details how ethical standards were maintained, including informed consent and IRB approval, ensuring the protection of human subjects.

Correct answer: C. Ask, gather, assess and appraise, act, and evaluate

Explanation of the correct answer:

C. Ask, gather, assess and appraise, act, and evaluate

The correct sequence for implementing evidence-based practice (EBP) in nursing involves several key steps:

Ask: The first step in EBP is to identify a clinical question or problem that needs to be addressed. Nurses should ask a clear and focused clinical question, often using the PICO(T) format (Patient/Problem, Intervention, Comparison, Outcome, and Time).

Gather: After the question is defined, the next step is to gather the best available evidence. This can involve reviewing clinical research studies, guidelines, and other sources of evidence that are relevant to the question posed.

Assess and appraise: Once evidence is gathered, it must be critically appraised for quality, relevance, and applicability to the specific clinical situation. This involves evaluating the strength of the evidence and determining whether it is robust enough to be applied in practice.

Act: In this step, nurses implement the evidence into practice, incorporating it into their clinical decision-making and patient care. The action taken should be based on the best evidence available.

Evaluate: After implementing the evidence-based intervention, the nurse evaluates the outcome to determine if the desired change or improvement in patient care has occurred. This helps to assess the effectiveness of the intervention and informs future practice.

This sequence ensures a structured, systematic approach to evidence-based practice that is focused on improving patient care and outcomes.

Why the other options are incorrect:

A. Evaluate, act, appraise and assess, gather, and ask

This option places "evaluate" and "act" at the beginning, which are later steps in the EBP process. Evaluation should occur after the intervention has been implemented to assess its effectiveness.

B. Appraise and assess, act, ask, gather, and evaluate

In this option, the sequence starts with "appraise and assess" and "act" before the evidence is even gathered. This does not follow the logical order of EBP steps. The assessment and appraisal of evidence should come after gathering it.

D. Gather, ask, evaluate, act, appraise and assess

This option incorrectly places "ask" after "gather," and it also improperly orders the steps of "appraise and assess" and "evaluate." The asking of a clinical question is the initial step in the EBP process, not something that comes after gathering evidence.

Summary:

The proper sequence for evidence-based practice involves asking a clear clinical question, gathering relevant evidence, assessing and appraising that evidence, implementing the evidence-based interventions, and then evaluating the outcomes. This systematic approach ensures that patient care is grounded in the best available evidence, ultimately leading to better outcomes.

Correct answers: B, C

Explanation of the correct answers:

B. Nonexperimental designs are used to test relationships among variables.

Nonexperimental designs are often used to examine relationships between variables, but they do not involve manipulation of the independent variable. Instead, researchers observe and measure variables as they naturally occur. This allows researchers to test whether and how variables are related, without attempting to influence or control them.

C. Nonexperimental designs can be used to construct a picture of a phenomenon at one point in time.

Nonexperimental designs, such as cross-sectional studies, are commonly used to gather data at one specific point in time. These studies provide a snapshot of a phenomenon or population at a particular moment, without manipulation or control over the variables.

Why the other options are incorrect:

A. In nonexperimental studies, the independent variable is manipulated.

This statement is false. In nonexperimental studies, the independent variable is not manipulated. Instead, researchers observe existing variables and their relationships without intervention. Manipulation of variables is characteristic of experimental designs, not nonexperimental ones.

D. In nonexperimental studies, subjects are randomly selected.

While random selection can occur in nonexperimental studies, it is not a defining characteristic. Nonexperimental studies often use convenience sampling or other nonrandom selection methods. Random selection is more closely associated with experimental or quasi-experimental designs to ensure generalizability.

Summary:

Nonexperimental designs are useful for testing relationships among variables (B) and for constructing a picture of a phenomenon at one point in time (C). However, they do not involve manipulation of the independent variable (A) or necessarily random selection of subjects (D).

Correct answer: A. Cohort, B. Descriptive, D. Prospective

Explanation of the correct answer:

A. Cohort

A cohort design follows a group of people over a period of time to observe how certain variables or factors impact outcomes. In this case, following new mothers from childbirth to 1 month postpartum to identify predictors of parenting self-efficacy aligns with a cohort design, as it tracks participants at different time points.

B. Descriptive

A descriptive design aims to describe and understand characteristics or phenomena. The nurse researcher seeks to identify factors related to parenting self-efficacy, so a descriptive design is appropriate to capture and analyze these variables.

D. Prospective

A prospective design tracks participants forward in time. Since the researcher is interested in predicting parenting self-efficacy at specific time points (12 to 48 hours after childbirth and at 1 month postpartum), a prospective design is fitting as it involves measuring outcomes at future time points.

Why the other option is incorrect:

C. Longitudinal with retrospective

A longitudinal with retrospective design would involve collecting data from past records or events and following participants over time. Since the study is focused on collecting data at specific future time points after childbirth, this design does not apply here.

Summary: A cohort, descriptive, and prospective design are appropriate for studying predictive factors of parenting self-efficacy at multiple time points after childbirth.

Correct answer: A. Right to fair treatment and protection

Explanation of the correct answer:

A. Right to fair treatment and protection

The 1994 Ivory Coast, Africa research study violated the right to fair treatment and protection because the research conducted involved unethical practices. In this case, it was reported that researchers tested a new treatment for HIV on pregnant women without proper consent and without considering the potential risks and the vulnerable status of the participants. The ethical principle of fair treatment and protection demands that all participants in research be treated with fairness and that their rights are respected, particularly in terms of ensuring their safety and well-being. The violation in this study included not protecting the participants from harm and not ensuring they were treated fairly.

Why the other options are incorrect:

B. Right to institutional approval of program before implementation

While institutional approval is an important ethical consideration in research, particularly regarding the review of protocols to ensure ethical standards, the specific violation in the Ivory Coast study was more about the lack of fair treatment and protection of participants, not about the absence of institutional approval. The ethical breach was more concerned with the treatment of individuals during the study, not the approval process.

C. Right to freedom from coercion or constraint

This principle is concerned with ensuring that participants are not coerced or forced into participation. While the Ivory Coast study likely involved some elements of coercion, the primary violation was more about the lack of fair treatment and protection, such as failing to ensure that participants were properly informed or safeguarded. Coercion is part of this violation, but it wasn't the central ethical issue.

D. Right to be informed about the purpose of the research

While informed consent and understanding the purpose of research are critical, the core issue in the Ivory Coast study involved the overall lack of protection for participants, which included improper consent procedures and exposing them to risk without adequate safeguards. The issue went beyond just informing the participants and extended to their treatment and protection throughout the study.

Summary:

The 1994 Ivory Coast study violated the right to fair treatment and protection, as participants were exposed to potential harm, lacked proper informed consent, and were not protected in line with ethical research standards. This highlights the importance of safeguarding participants' well-being and ensuring that they are treated fairly in all research studies.

Correct answer: C. Extraneous

Explanation of the correct answer:

C. Extraneous

In a research study, extraneous variables are variables that are not the focus of the study but can affect the outcome if not controlled. The nurse researcher should strive for subjects to demonstrate homogeneity with respect to extraneous variables to reduce their potential influence on the dependent variable. This means that any external or unrelated factors that could affect the outcome should be minimized by ensuring subjects are similar in those aspects.

Why the other options are incorrect:

A. Independent

The independent variable is manipulated or categorized by the researcher to observe its effect on the dependent variable. Homogeneity with respect to independent variables is generally not the goal, as variations in the independent variable are required to explore its effect.

B. Dependent

The dependent variable is what is measured in the study, and it is expected to change in response to the independent variable. Homogeneity with respect to dependent variables is not typically desired, as researchers are interested in variations in the dependent variable as a result of the intervention or treatment.

D. Outcome

The term "outcome" refers to the result or effect that is measured in the study, which is often linked to the dependent variable. Researchers aim to measure changes in the outcome based on the independent variable, but homogeneity in outcomes is not generally the goal, as differences in outcomes are what are being studied.

Summary:

Homogeneity with respect to extraneous variables is important to ensure that these variables do not interfere with the study results, leading to more accurate and valid conclusions.

Correct answer: C. The study was approved by an institutional review board.

Explanation of the correct answer:

C. The study was approved by an institutional review board (IRB)

The institutional review board (IRB) is responsible for ensuring that research involving human participants adheres to ethical standards. This includes ensuring that participants' rights are protected, informed consent is obtained, and risks are minimized. Approval from the IRB is a key indicator that the research has been reviewed and deemed to meet ethical guidelines. The IRB is tasked with overseeing the ethical aspects of a study, and their approval is essential for ensuring that ethical standards are met.

Why the other options are incorrect:

A. The reliability and validity of each measure were discussed

While discussing the reliability and validity of the measures is important for ensuring the quality and accuracy of the research instruments, it does not directly speak to whether the study has met ethical standards. Ethical standards primarily focus on the protection of participants, informed consent, and minimizing harm, rather than the technical quality of the measures.

B. The data analysis procedures are thoroughly discussed

While the data analysis procedures are important for understanding how the data were handled and ensuring the scientific rigor of the study, they do not address whether the research adhered to ethical principles. Ethical considerations involve how participants are treated, which is not directly related to the analysis procedures.

D. The sampling techniques used were discussed

Discussing the sampling techniques is important for the validity and generalizability of the study findings, but it does not directly address ethical standards. Ethical standards focus on how participants are selected, treated, and protected during the study, rather than on the techniques used to sample them.

Summary:

The institutional review board (IRB) approval is the best indicator that a research study has met ethical standards, as the IRB ensures the protection of participants and that the study adheres to ethical guidelines before it begins.

Correct answer: C. Descriptive longitudinal

Explanation of the correct answer:

C. Descriptive longitudinal

This study is best described as a descriptive longitudinal design because it involves observing and measuring the frequency of medical errors made by new nursing graduates over time. Longitudinal studies are conducted over an extended period, collecting data at multiple points to track changes or developments. In this case, the study follows the same cohort of new graduates at 6 months, 9 months, and 1 year postgraduation. The study is descriptive because the primary purpose is to observe and describe the occurrence of medical errors, without manipulating variables or exploring causal relationships.

Why the other options are incorrect:

A. Correlational predictive

A correlational predictive design examines relationships between variables to predict outcomes, but this study does not aim to predict the frequency of medical errors based on other variables. Instead, it is simply observing and measuring errors over time, which makes it a descriptive rather than a predictive study.

B. Retrospective correlational

A retrospective correlational design typically looks at past data to investigate relationships between variables, often using existing records or reports. In this study, the data is being collected in real-time from new graduates, not retrospectively from past records or events. Therefore, this is not a retrospective study.

D. Comparative descriptive

A comparative descriptive design involves comparing different groups or conditions while describing their characteristics. This study does not involve comparing different groups; instead, it follows one group of new graduates over time. Hence, it is not a comparative study.

Summary:

The study tracks the same group of new nursing graduates over time to measure medical errors, which makes it a descriptive longitudinal study.

Correct answer: A. Developmental studies

Explanation of the correct answer:

A. Developmental studies

Developmental studies specifically focus on changes over time and are concerned with the study of how people or phenomena develop, grow, or change across different stages or periods. These studies often involve assessing participants at multiple time points to track progress or changes, such as examining childhood development, aging, or changes in health conditions over time. A major component of developmental studies is a time perspective, as they aim to explore the dynamics of change over a specific period, making time a central factor in the study's design.

Why the other options are incorrect:

B. Cross-sectional studies

Cross-sectional studies do not primarily focus on time perspectives. They are observational studies that collect data from participants at one specific point in time, providing a snapshot of a particular phenomenon. While cross-sectional studies can help identify relationships between variables, they do not track changes over time, which makes them less concerned with a time perspective.

C. Descriptive studies

Descriptive studies aim to describe characteristics of a population or phenomenon but do not specifically focus on changes over time. These studies provide a detailed account of what is happening at a particular point in time without examining trends or patterns of change over time.

D. Causal modeling studies

Causal modeling studies are concerned with understanding the cause-and-effect relationships between variables, but they do not necessarily focus on a time perspective. While some causal models may incorporate time-based data, their primary aim is to identify and model the relationships between variables rather than studying changes over time.

Summary:

Developmental studies are the type of studies that focus specifically on time perspectives, as they are concerned with understanding how something evolves, grows, or changes over time.
