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.
