NRS-465 Topic 1 DQ 1 Study Guide

If you’re staring at the first discussion question in GCU’s NRS-465 capstone, you’re being asked to do something more specific than “talk about EBP.” This guide breaks down exactly what the prompt wants, gives you the real scholarship behind the answer, and shows you how to structure an initial post and peer responses that satisfy the RN-BSN Discussion Question Rubric and the RN-BSN Participation Rubric — so you can write a strong submission in your own words.

How to use this guide: Everything below is here to help you understand and construct your own response. Your instructor can tell when a post isn’t your own voice, and the whole point of NRS-465 is building the EBP judgment you’ll actually use at the bedside. Read this, then write it yourself.

Topic 1 DQ 1

In preparation for your assignment this week, brainstorm two to three clinical practice problems or issues you can develop into a nursing practice change. What indicates these as clinical issues in nursing practice? Support your discussion with two peer-reviewed journal articles.

Initial discussion question posts should be a minimum of 200 words and include at least two references cited using APA format. Responses to peers or faculty should be 100-150 words and include one reference. Refer to “RN-BSN Discussion Question Rubric” and “RN-BSN Participation Rubric,” located in Class Resources, to understand the expectations for initial discussion question posts and participation posts, respectively.

What this DQ is actually asking

Read the prompt closely and you’ll see it has three moving parts. A post that misses any one of them loses rubric points:

1. Context to acknowledge: The National Academy of Medicine (formerly the IOM) set a goal that 90% of clinical decisions be evidence-based by 2020, yet systematic reviews show implementation is still falling short. You don’t need to argue this — you need to show you understand the gap between the goal and reality.
2. The core task — two barriers: Identify exactly two barriers that keep nursing practice from reaching that goal. Not one, not five. Two, each developed with enough depth to show critical thinking.
3. The second half people forget — how to address them: For each barrier, propose a realistic, evidence-supported way to overcome it. Half the question is the solution. A post that lists two barriers and stops will cap out around half marks no matter how well-written it is.

So the skeleton of a high-scoring answer is: acknowledge the gap → Barrier 1 + how to address it → Barrier 2 + how to address it → close. Two references, APA 7, 200 words minimum.

The landscape of EBP barriers (pick two — understand all of them)

The nursing literature on why EBP stalls is remarkably consistent. Below are the most well-documented barriers with the mechanism behind each — because the rubric rewards explaining why something is a barrier, not just naming it. Choose the two you can speak to most convincingly, ideally ones you’ve seen on your own unit.

1. Lack of time and heavy workload. This is the single most-cited barrier across studies. Bedside nurses rarely have protected time to formulate a clinical question, search databases, appraise studies, and translate findings into practice — those tasks compete directly with direct patient care and documentation. When staffing is tight, EBP work is the first thing dropped.

2. Insufficient EBP knowledge and skills. Many nurses were never trained to write a PICOT question, search CINAHL effectively, or critically appraise a study’s design and statistics. A landmark national U.S. study found nurses did not rate themselves as competent in any of the 24 EBP competencies measured, with a mean self-rated score of just 53.5 out of 96 (Melnyk et al., 2018). You can’t implement what you were never taught to do.

3. Weak organizational culture and limited leadership support. EBP thrives in a “spirit of inquiry” culture where asking why do we do it this way? is encouraged and resourced. Where leaders don’t prioritize, model, or fund EBP, individual nurses’ efforts stall. Culture and mentorship have been shown to predict whether EBP actually gets implemented (Melnyk et al., 2021).

4. Lack of EBP mentors and champions. Even motivated nurses need someone to guide them through their first project. Without designated EBP mentors, the knowledge gap above never closes and momentum dies after the first obstacle.

5. Limited access to evidence and limited authority to change practice. Some nurses lack easy access to databases or full-text articles; others have the evidence but no authority within the unit’s governance structure to actually change a protocol. Both turn good intentions into dead ends. These resource and autonomy barriers recur across international reviews (Shayan et al., 2019).

6. Resistance to change. The “we’ve always done it this way” reflex is real. Changing entrenched routines requires demonstrating value, not just citing a study.

Tip: The strongest posts pair barriers that operate at different levels — e.g., one individual barrier (knowledge/skills) and one system barrier (time/workload or culture). That shows you understand EBP failure isn’t just a personal shortcoming.

Pairing each barrier with a way to address it

This is where most of the critical-thinking points live. For whichever two barriers you choose, propose a specific, realistic solution — not “more education” in the abstract. Examples of evidence-aligned directions you can develop in your own words:

• For time/workload: protected EBP time built into the schedule, embedding evidence checks into existing workflows (e.g., at shift huddles), or unit-based EBP rounds so the work is shared rather than added on top of a full assignment.
• For knowledge/skills deficits: structured EBP education and continuing-education modules, EBP fellowships, and integrating the EBP competencies into onboarding so new nurses arrive with the skill set (Melnyk et al., 2018).
• For culture/leadership: adopting a formal implementation model such as the ARCC (Advancing Research and Clinical practice through close Collaboration) model, in which EBP mentors and a supportive culture drive uptake (Melnyk et al., 2021); visible leadership sponsorship and recognition for nurses who lead changes.
• For mentorship gaps: creating designated EBP mentor or champion roles on each unit.
• For access/authority: ensuring database and library access, and using shared-governance councils to give bedside nurses real authority to revise protocols.

Choose solutions that logically match the barrier you named — graders notice when the “fix” doesn’t actually address the stated problem.

How to structure a 200-word initial post that hits the rubric

The RN-BSN Discussion Question Rubric generally rewards four things: a clear and complete answer to the question, scholarly support, critical thinking/depth, and correct APA. Here’s an annotated skeleton you can fill in with your own analysis — these are slots and word budgets, not a script:

• Opening (~25–30 words): Briefly acknowledge the NAM 90% goal and the persistent implementation gap. One or two sentences. This frames your answer and shows you read the prompt’s context.
• Barrier 1 + solution (~70 words): Name the barrier, explain why it blocks EBP (the mechanism), then give your specific way to address it. Cite a source here.
• Barrier 2 + solution (~70 words): Same structure, a barrier at a different level. Cite your second source here.
• Close (~20 words): One sentence connecting your solutions back to the patient-care or quality goal the NAM target was about.

That comes to roughly 185–210 words, which clears the 200-word minimum with substance rather than filler. Write each slot in your own voice, then check it against the rubric language before posting.

Writing peer responses that earn full participation points

The Participation Rubric wants 100–150 word responses that add something — not “Great post, I agree!” A response that scores well usually does three things: affirms or engages a specific point your peer made, extends it with a new idea or piece of evidence, and includes one scholarly reference in APA.

A simple framework you can adapt:

1. Engage specifically (1 sentence): Reference the exact barrier or solution your peer raised, so it’s clearly a response to their post.
2. Extend (2–3 sentences): Add a complementary barrier, a counterpoint, a clinical example from your own practice, or supporting evidence they didn’t mention.
3. Support + close (1 sentence + citation): Tie in one reference and end with a forward-looking thought or question.

For example, an opening line might engage like: “Your point about protected time resonates with what I’ve seen on a med-surg floor, where…” — then you’d develop the idea and cite a source. Write the full response yourself; that personal clinical detail is exactly what makes peer responses authentic and high-scoring.

APA 7 and formatting pitfalls that quietly cost points

• Two references means two scholarly references — peer-reviewed nursing journals, ideally within the last 5 years. Your textbook alone usually isn’t enough.
• In-text citation on every borrowed idea, not just at the end of the paragraph. Match each in-text citation to a full reference.
• DOIs as live URLs in the reference list (e.g., https://doi.org/10.1111/wvn.12269), formatted per APA 7.
• Word count counts your prose, not your references — hit 200 words of actual discussion.
• Hanging indents and alphabetical order in the reference list. Small, but rubrics check it.

Common mistakes to avoid

• Listing two barriers but forgetting to address them (missing half the prompt).
• Naming a barrier without explaining the mechanism — depth is where critical-thinking points live.
• Choosing a “solution” that doesn’t actually fix the barrier you named.
• Using only old or non-scholarly sources.
• Going under 200 words, or padding to 200 with restated prompt text.

Frequently asked questions

How many barriers does NRS-465 Topic 1 DQ 1 ask for? Exactly two. Identify two barriers and, for each, suggest a realistic way to address it. The solution half carries as much weight as the barrier half.

How long should the initial post be? A minimum of 200 words, with at least two scholarly references in APA 7 format. Peer/faculty responses should be 100–150 words with one reference.

What are the most common barriers to EBP implementation in nursing? Lack of time and heavy workload, insufficient EBP knowledge and skills, weak organizational culture and leadership support, lack of mentors, limited access to evidence, limited authority to change practice, and resistance to change.

Can I use my textbook as one of the two references? You can cite it, but pair it with at least one current peer-reviewed journal article. Most rubrics expect scholarly, recent (within ~5 years) sources.
