Mary is a newly-hired, new graduate nurse. Mary adapts her practice to imitate her co-workers on the unit. She is demonstrating:

A. Evaluate the quality of the research against the standards for that type of research: Assessing research quality based on established standards ensures that the study's design, methodology, and findings are reliable and valid for its particular research type.
B. Select only studies with a sample size of at least 100 people: While sample size is important, it is not the sole determinant of a study's quality. Other factors like study design, methodology, and relevance also play crucial roles.
C. Discard systematic reviews and meta-analyses since they are the weakest form of evidence: Systematic reviews and meta-analyses are actually considered high levels of evidence as they synthesize data from multiple studies, providing comprehensive insights.
D. Accept only studies that use a randomized controlled trial design: While RCTs are a gold standard for certain types of research, other study designs are also valuable and appropriate depending on the research question and context.

A. Surgery to the wrong site was stopped prior to a procedure: This incident was prevented before harm occurred and is not considered a sentinel event since no actual harm was inflicted.
B. Paralysis of a client's lower extremities occurred following epidural anesthesia: This represents a significant adverse outcome that has resulted in severe harm and is considered a sentinel event, which requires thorough investigation and response.
C. A client fall during ambulation did not result in client injury: Although falls are a concern, the lack of injury means this incident may not be classified as a sentinel event.
D. A complaint that a nurse was culturally insensitive was made by a client's family member: While important for addressing care quality and communication, this complaint does not typically constitute a sentinel event as it does not directly involve significant harm or risk.
