A nurse is designing a study to evaluate the effectiveness of preoperative teaching to clients undergoing total knee replacement surgery.
To best identify previous research studies that investigated client teaching effectiveness, what should the nurse do first?
Interview clients to determine if they remembered concepts taught preoperatively.
Read full-text articles in nursing journals about designing client teaching sessions.
Ask orthopedic surgeons what topics should be covered preoperatively with clients.
Review research abstracts on preoperative teaching with a similar client population.
The Correct Answer is D
Choice A rationale:
Interviewing clients to determine if they remembered concepts taught preoperatively does not represent the first step in identifying previous research studies. It focuses on assessing the retention of teaching rather than reviewing existing literature.
Choice B rationale:
Reading full-text articles in nursing journals about designing client teaching sessions is valuable but not the first step in identifying previous research studies. It focuses on teaching session design rather than the literature review process.
Choice C rationale:
Asking orthopedic surgeons about topics to cover preoperatively with clients is a form of expert consultation but does not represent the first step in identifying previous research studies. It involves seeking expert input rather than reviewing existing literature.
Choice D rationale:
This is the correct answer. Reviewing research abstracts on preoperative teaching with a similar client population is typically the first step in conducting a literature review. It allows the nurse to identify relevant research studies that have investigated the effectiveness of preoperative teaching in a similar context.

Correct Answer is D
Explanation
Choice D rationale:
A randomized controlled trial that concluded individual and group education achieve similar results. Rationale: Randomized controlled trials (RCTs) are considered the gold standard for assessing the effectiveness of interventions. In this case, an RCT concluded that individual and group education achieve similar results, providing strong evidence for decision-making in the diabetes management clinic.
Choice A rationale:
A descriptive study that found a positive link between individual teaching and blood glucose levels. Rationale: Descriptive studies provide valuable information but do not establish causal relationships. A positive link between individual teaching and blood glucose levels may suggest an association but does not necessarily demonstrate effectiveness.
Choice B rationale:
A qualitative study that interviewed subjects and found that they preferred individual education. Rationale: Qualitative studies explore preferences and experiences but do not typically provide evidence of effectiveness in terms of health outcomes or clinical practice.
Choice C rationale:
A cost analysis study that determined group education was less costly than individual education. Rationale: Cost analysis studies focus on economic aspects and cost-effectiveness but may not address clinical effectiveness or outcomes. The best evidence for clinical decision-making typically comes from RCTs.
Correct Answer is A
Explanation
Choice A rationale:
True random sampling. True random sampling ensures that each client discharged from the postoperative orthopedic unit after joint replacement surgery has an equal and independent chance of being selected for the study. This approach minimizes bias and enhances the generalizability of the study findings to the entire population of interest.
Choice B rationale:
Stratified random sampling involves dividing the population into subgroups (strata) and then randomly selecting samples from each stratum. While this approach can be useful for ensuring representation of specific subgroups, it may not be necessary if the goal is to have an equal chance of participation for all clients.
Choice C rationale:
Convenience sampling involves selecting participants based on their availability and accessibility. It is not suitable for this study, as it may introduce bias and not ensure equal chances of participation for all clients.
Choice D rationale:
Quota sampling involves selecting participants based on predefined quotas for specific characteristics. It is not the most suitable method for ensuring equal chances of participation for all clients in this study.
