A nurse is reviewing a research article that compared Hemoglobin A1c (HbA1C) findings of randomly selected 20 to 30-year-old clients with diabetes who participated in a specified 3- month strenuous exercise program with 20 to 30-year-old clients who did not participate in the exercise program. Which research design describes this study?
Correlational.
Exploratory.
Experimental.
Developmental.
The Correct Answer is C
A. Correlational studies examine the relationship between variables but do not involve manipulation of variables, which is a key characteristic of experimental studies.
B. Exploratory studies aim to explore a new area or phenomenon, often using qualitative methods or preliminary investigations, which may not involve comparing groups with different interventions.
C. Experimental studies involve the manipulation of an independent variable (in this case, participation in the exercise program) to observe its effects on a dependent variable (HbA1C findings). This design allows for causal inferences about the relationship between the intervention and outcome.
D. Developmental studies focus on changes over time or across different life stages, which may involve longitudinal or cross-sectional designs but do not necessarily involve experimental manipulation of variables.

Correct Answer is C
Explanation
A. While halving the first dose of a narcotic may be a clinical decision, it does not necessarily reflect the adoption of evidence-based practice unless supported by research or clinical guidelines.
B. Adjusting bathing frequency for dependent clients may be a clinical decision, but it does not necessarily reflect the adoption of evidence-based practice unless supported by research or clinical guidelines.
C. Discarding certain antimicrobials after being linked to increased nosocomial infection rates demonstrates the adoption of evidence-based practice as it involves making clinical decisions based on evidence from research that identified a link between certain antimicrobials and increased infection rates.
D. Recording vital signs every shift on stable clients per hospital-wide policy may be a standard practice, but it does not necessarily reflect the adoption of evidence-based practice unless supported by evidence from research or clinical guidelines.
Correct Answer is C
Explanation
A. While replicating the study using adolescents from across the United States could provide broader generalizability, it may not be necessary if the goal is to investigate the effectiveness of other smoking cessation programs.
B. Surveying the adolescents' families to determine how many family members smoke may provide useful information but does not directly address the effectiveness of other smoking cessation programs.
C. Investigating the effectiveness of other smoking cessation programs is warranted based on the findings that Program A was more effective than Program B. This action allows for comparison with alternative interventions to determine the most effective approach for smoking cessation among adolescents.
D. Providing all smoking adolescents in the three high schools with Program A assumes that Program A is universally effective, which may not be the case. It is important to explore other options and consider individual preferences and needs when selecting a smoking cessation program.
