A nursing student wants to retrieve information about nurse-authored client education programs that have resulted in a reduction of sexually transmitted infection (STI) rates among American teenagers. Which source is likely to provide the greatest amount of usable material concerning this topic?
Cumulative Index of Nursing and Allied Health Literature (CINAHL) reference.
Google Internet meta-search engine search by subject matter (STIs).
American College of Obstetricians and Gynecologists Website for the public.
US Department of Health and Human Services epidemiology webpage.
The Correct Answer is A
A. CINAHL is a specialized database focusing on nursing and allied health literature, making it the most relevant source for retrieving nurse-authored client education programs on STIs among American teenagers.
B. While a Google search may yield various sources, including relevant information, it may also provide a plethora of unrelated or non-authoritative sources, making it less efficient for this specific research need.
C. The American College of Obstetricians and Gynecologists website may offer valuable information but may not specifically focus on nurse-authored client education programs or may not include extensive research studies.
D. The US Department of Health and Human Services epidemiology webpage may offer data and reports on STIs but may not specifically focus on nurse-authored client education programs or provide detailed studies.

Correct Answer is B
Explanation
A. Longitudinal studies follow the same group of subjects over a long period, which may not be feasible or practical for investigating the immediate effects of teaching.
B. Experimental designs involve the manipulation of an independent variable (teaching about nutrition, wound care, and maintenance of normal blood sugar levels) to observe its effects on a dependent variable (such as knowledge retention or behavior change). This design allows for the comparison of outcomes between a group that receives the intervention and a control group, providing the best indication of the effects of the teaching intervention.
C. Cross-sectional studies examine different groups at a single point in time and may not provide the best indication of the effects of teaching over time.
D. Descriptive studies aim to describe characteristics or behaviors of a population but do not typically involve interventions or manipulation of variables.
Correct Answer is B
Explanation
A. While a literature review may discuss the potential implications of the study findings for future research or practice, its primary purpose is to provide background information and theoretical framework for the research question.
B. Providing a context for the research question involves describing relevant theories, concepts, and findings from previous studies that inform the current study. This helps justify the research question, refine hypotheses or research objectives, and guide methodology and interpretation of results.
C. Ensuring that the study has not already been completed is one aspect of a literature review, but its broader purpose is to review existing literature to build on previous knowledge and identify gaps in the literature that the current study can address.
D. While the literature review may provide insights into different research designs used in previous studies, its primary purpose is not to identify the research design or explain the rationale for choosing the research methodology.
