A charge nurse is discussing evidence-based practice (EBP) and the hierarchy of evidence with a newly licensed nurse.
Which of the following examples should the nurse provide when discussing Level I evidence?
Systematic review.
Credible websites.
Expert opinions.
Qualitative studies.
The Correct Answer is A
Choice A rationale:
Systematic reviews are considered Level I evidence in the hierarchy of evidence in evidence-based practice (EBP). Systematic reviews involve the rigorous and comprehensive synthesis of multiple research studies on a specific topic. This approach minimizes bias and provides the highest level of evidence for making clinical decisions. Systematic reviews typically follow a structured methodology and offer a critical analysis of the existing literature, making them a strong foundation for EBP.
Choice B rationale:
Credible websites are not considered Level I evidence. While some websites may contain reliable information, they vary in quality, and the credibility of the source must be carefully assessed. Relying solely on websites is not the most robust approach in EBP, as it lacks the rigorous systematic review and critical appraisal process of Level I evidence.
Choice C rationale:
Expert opinions are not considered Level I evidence. While expert opinions can be valuable, they are often based on individual experiences and interpretations rather than systematic research. Expert opinions are generally considered lower in the hierarchy of evidence compared to systematic reviews and other forms of research evidence.
Choice D rationale:
Qualitative studies are not considered Level I evidence. Qualitative studies provide valuable insights into the experiences, perceptions, and meanings associated with a particular phenomenon. However, they are typically ranked lower in the hierarchy of evidence compared to systematic reviews and quantitative research studies. Qualitative studies are more appropriate for addressing research questions related to subjective experiences and understanding the "why" and "how" of a phenomenon.

Correct Answer is A
Explanation
Correct Answer is ["C","D","E"]
Explanation
The correct answer is to select the following three findings that require immediate follow-up:C. Urticaria,D. Blood pressure at 1630, andE. Report of dysphagia.
Choice A rationale:
“Breath sounds at 1600.” The breath sounds at 1600 were clear and present throughout, which is a normal finding and does not require immediate follow-up.
Choice B rationale:
“Temperature.” The temperature readings at both 1600 and 1630 are slightly elevated but not critically high. This does not require immediate follow-up compared to the other findings.
Choice C rationale:
“Urticaria.” The presence of urticaria (hives) indicates an allergic reaction, which can potentially escalate to a more severe reaction such as anaphylaxis.Immediate follow-up is necessary to prevent further complications.
Choice D rationale:
“Blood pressure at 1630.” The blood pressure at 1630 is significantly lower (78/52 mm Hg) compared to the earlier reading (110/58 mm Hg).This hypotension could indicate a serious reaction to the medication or another underlying issue that requires prompt attention.
Choice E rationale:
“Report of dysphagia.” The client’s report of difficulty swallowing and feeling a lump in their throat is concerning for a potential airway obstruction or severe allergic reaction, such as anaphylaxis.This symptom requires immediate follow-up to ensure the client’s airway remains open and to provide necessary interventions.
