NRS-445 Assignment Guide
NRS-445 is the course where GCU’s RN-to-BSN program teaches you to use research — to find evidence, judge whether it’s any good, and turn it into a practice recommendation. Almost everything you do in this five-week course is one connected thread: build a PICOT question, find the evidence, appraise it, synthesize it, and propose a change. This guide walks you through that thread, links you to a full breakdown of each assignment, and shows you how NRS-445 sets up your capstone — all in a way that helps you do the work yourself.
How to use this guide: This is a teaching resource. Each section explains how an assignment works and what graders look for, then points you to a deeper walkthrough. The goal is to help you produce your own work with confidence — which is exactly the EBP skill this course is built to give you.

Where NRS-445 sits: the EBP learning spine
NRS-445 doesn’t stand alone — it’s the middle of a three-course progression, and understanding that makes the whole course easier:
- HLT-362V (Applied Statistics) — your prerequisite. The stats you learned there (p-values, confidence intervals, study designs) are exactly what you’ll use to appraise research in this course. If a concept feels shaky, revisit your HLT-362V material.
- NRS-445 (this course) — where you learn the EBP method end to end.
- NRS-465 (capstone) — where you apply that method to a real practice-change project. The PICOT and Literature Evaluation Table you build here reappear in the capstone.
Treat NRS-445 as the dress rehearsal for your capstone. Choosing a clinical problem you genuinely care about now pays off twice.
The NRS-445 assignment roadmap
Here’s every major assignment, what it’s really asking, and a link to its full walkthrough. They’re listed in the order the course builds them.
Weekly discussion questions (Topics 1–5)
The DQs scaffold your project. Early ones get you identifying a clinical problem and a PICOT question; later ones build toward appraisal and synthesis. Each initial post is 200+ words with two scholarly references; peer responses are 100–150 words with one reference. → Full walkthroughs: Topic 1 DQ 1 · Topic 1 DQ 2 and the rest of the DQ set.
The PICOT question
The foundation of everything else. A complete PICOT names the Population, Intervention, Comparison, Outcome, and Time, and frames a problem nurses can actually influence. Get this right and the rest of the course flows from it; get it vague and every later assignment fights you. → Full guide: How to write an NRS-445 PICOT question.
Literature Evaluation Table
You locate four peer-reviewed primary research articles — two quantitative and two qualitative — tied to your PICOT, and summarize each in a structured table (design, sample, results, relevance). This is where many students lose time, because finding primary qualitative and quantitative studies takes search skill. → Full guide: NRS-445 Literature Evaluation Table.
Critical appraisal — quantitative (CASP RCT checklist)
You take one quantitative study and judge its trustworthiness using the CASP Randomized Controlled Trial checklist: Was the design sound? Do the benefits outweigh harms and costs? This is where your HLT-362V statistics pay off. → Full guide: NRS-445 quantitative critical appraisal.
Critical appraisal — qualitative (CASP Qualitative checklist)
The same skill applied to a qualitative study, using the CASP Qualitative checklist — judging rigor, credibility, and how findings were derived. Knowing why the criteria differ from quantitative appraisal is what earns the marks. → Full guide: NRS-445 qualitative critical appraisal.
Literature review (synthesis)
Here you stop summarizing article-by-article and start synthesizing — weaving findings across your studies into themes that answer your PICOT and point toward a practice change. Synthesis vs. summary is the single most common stumbling point. → Full guide: NRS-445 literature review.
Research Critiques and EBP Proposal (final paper)
The culminating assignment pulls the whole thread together: your problem, your appraised evidence, and a proposed evidence-based practice change. It’s the bridge to your capstone. → Full guide: NRS-445 EBP proposal.
How the assignments connect
If you see NRS-445 as seven unrelated tasks, it feels overwhelming. See it as one project in stages and it gets simple:
Problem → PICOT → find evidence → appraise evidence → synthesize → propose a change.
Every assignment is one link in that chain. The clinical problem you pick in your early DQs becomes your PICOT; the PICOT drives your Literature Evaluation Table; those articles get critically appraised; the appraisals feed your literature review; and the review supports your final EBP proposal. Pick a strong, narrow, nurse-influenceable problem at the start and the whole chain holds together.
How NRS-445 sets up your NRS-465 capstone
This is the part savvy students use to their advantage. The capstone (NRS-465) asks for a PICOT, a Literature Evaluation Table, and an evidence-based change project — the same building blocks you create here. If you choose a capstone-worthy clinical problem in NRS-445 and do the work well, you walk into NRS-465 with your foundation already built. → See the NRS-465 capstone guide and the Literature Evaluation Table as it’s used in the capstone.
Study tips and common pitfalls
- Dust off your HLT-362V stats. Critical appraisal is impossible if p-values and study designs are a blur. A quick refresher up front saves hours later.
- Nail “primary” and “peer-reviewed.” The Literature Evaluation Table needs primary research — original studies, not reviews or summaries. Use the GCU Library’s CINAHL and MEDLINE filters.
- Learn the two CASP checklists. Quantitative and qualitative appraisal ask different questions for good reasons; know why.
- Synthesize, don’t summarize. In the literature review, organize by theme, not by article. This is the most common point loss.
- Keep one clinical problem the whole way through. Switching problems mid-course forces you to redo earlier work.
- APA 7 throughout — in-text citations matched to references, DOIs as live links, and recent (within ~5 years) scholarly sources.

Frequently asked questions
What is NRS-445 about? NRS-445, Nursing Research & Evidence-Based Practice, teaches you to evaluate quantitative and qualitative research and translate it into practice through a PICOT-driven, evidence-based recommendation. Its prerequisite is HLT-362V.
What assignments are in NRS-445? Weekly discussion questions, a PICOT question, a Literature Evaluation Table (four primary research articles — two quantitative, two qualitative), quantitative and qualitative critical appraisals using CASP checklists, a literature review, and a final Research Critiques and EBP Proposal.
How hard is NRS-445? The workload is manageable if you keep one clinical problem throughout and refresh your HLT-362V statistics for the appraisal assignments. The biggest challenges are finding primary research and synthesizing rather than summarizing.
How does NRS-445 connect to the capstone? The PICOT, Literature Evaluation Table, and EBP recommendation you build in NRS-445 are the same building blocks used in the NRS-465 capstone, so strong work here gives you a head start.
Do I need statistics for NRS-445? Yes. Critical appraisal of quantitative studies relies on the statistics concepts from the HLT-362V prerequisite.
