This formative assessment focuses on your understanding and application of evidence-based practice (EBP) in nursing. It builds towards the summative assessment by requiring you to apply EBP principles in a real-world scenario. This case study will prepare you by honing your skills in critical thinking, research application, and patient-centered care. Understanding and implementing EBP is crucial for providing high-quality, up-to-date care that improves patient outcomes and advances the nursing profession.

Instructions:  

You are a registered nurse working in a medical-surgical unit. You’ve noticed that many patients are experiencing postoperative nausea and vomiting (PONV) despite receiving standard antiemetic medication. Your supervisor has asked you to research and propose an evidence-based intervention to address this issue.

• Your task is to: 
  • Conduct a brief literature search and identify at least two relevant, recent (within the last 5 years) research articles that address the clinical situation from the case study.
  • Critically appraise the evidence found in these articles, considering factors such as study design, sample size, and relevance to your patient population.
  • Based on the evidence and considering your clinical expertise, propose an intervention to reduce PONV in your unit.
• In your response, be sure to:
  • Clearly define EBP and its core principles
  • Demonstrate how each step of your process aligns with these principles
  • Reflect on any challenges you encountered in applying EBP and how you overcame them
  • Your case study response should be approximately 400-600 words.
• Use the following structure your response: 
  • Literature Search Summary
  • Evidence Appraisal
  • Proposed Intervention
  • Remember to cite your sources using APA format and include a reference list at the end of your document.
• write answer in word document.

Step-by-Step Student Guide for Completing Your Case Study

Step 1: Understand the Core of the Assignment
You’re being asked to solve a real clinical problem—postoperative nausea and vomiting (PONV)—through evidence-based practice (EBP). EBP combines:

• The best available research evidence

• Clinical expertise

• Patient preferences and values

Step 2: Begin with a Literature Search Summary

• Use databases like CINAHL, PubMed, or Google Scholar.

• Use keywords: postoperative nausea and vomiting, PONV prevention, antiemetic alternatives, nursing interventions PONV.

• Filter for articles published within the last 5 years.

• Choose two high-quality, peer-reviewed research articles.

• Summarize why these studies are relevant to your patient population and practice setting.

Step 3: Critically Appraise the Evidence
For each article, evaluate the following:

• Study Design: Is it a randomized control trial (RCT), cohort study, or qualitative study?

• Sample Size: Larger samples typically offer stronger evidence.

• Population Similarity: Are the patients similar to yours (e.g., adult surgical patients)?

• Findings: What intervention was tested, and what were the outcomes related to PONV?

• Strengths and Limitations: Any biases or issues with the study?

Step 4: Propose an Evidence-Based Intervention

• Use your clinical expertise alongside the evidence to choose the most effective and practical intervention.

• Example: Suggest adding acupressure or ginger supplements alongside pharmacological treatment if supported by evidence.

• Justify your intervention with data from the studies.

Step 5: Reflect on the EBP Process

• Mention any barriers (e.g., difficulty accessing articles, conflicting results).

• Share how you dealt with them (e.g., consulting a librarian, choosing the strongest study).

• Emphasize how the process improved your decision-making and will benefit your unit’s patient care.

Step 6: Format Your Paper Properly

• Use clear headings:

  • Literature Search Summary

  • Evidence Appraisal

  • Proposed Intervention

• Keep the word count between 400–600 words.

• Use APA 7th edition for in-text citations and your reference list.

Step 7: Final Touches

• Review for clarity, grammar, and logical flow.

• Check APA formatting one last time.

• Save your document in Word format (.docx) as required.
