NSG 660 Unit 3 in full: a source credibility comparison holding four sources against one question, each judged on authorship, funding, currency, citation and review. Searches like "nsg 660 unit 3 assignment example", "nsg660 unit 3 sample" and "nsg 660 unit 3 example" land here.
What a finished NSG 660 Unit 3 source credibility comparison looks like
The finished comparison is a set of parallel readings rather than a ranking exercise. One clinical question sits at the top and does not change. Four sources follow, chosen to be genuinely different in kind: guidance from a professional body, a primary study, a review of several studies, and something a patient or a colleague would plausibly find first, such as a hospital system's public page or a well produced health site. Each is read against the same questions: who wrote it and what they do, who paid for it or hosts it, when it was written and whether that matters for this question, what it cites and whether the citations say what the source claims, and what review it passed. A short reading closes by saying which source would serve which purpose, since none of them is useless.
How a NSG 660 Unit 3 example is structured
The question is fixed at the top so the four are compared on something rather than in general, and currency can be argued instead of assumed, as a question about a stable physiological fact ages differently from one about a treatment. The sources are chosen for contrast rather than for quality, since a comparison among three good studies teaches less than one including the page a patient would actually reach. Identical questions are asked in the same order of each, which makes the document readable across as well as down. Citation checking is given real room, because following a claim back to what it rests on is where most surprises in this unit occur. The closing assigns roles rather than a winner, saying which source answers which part of the question and which should not be leaned on.
One question fixed above the four
Sources are compared against a single clinical question, since credibility is never general and a page can be sound for one purpose and useless for another.
Sources chosen for contrast
The set deliberately includes what a colleague would find first, because a comparison among peer reviewed studies alone leaves the everyday problem untouched.
The same questions in the same order
Authorship, funding, date, citations and review are asked of every source, which is what lets a reader compare rather than read four descriptions.
Citations followed rather than counted
A reference list is checked against the claim it supports, since the gap between what a source cites and what it says is where surprises sit.
Currency argued against the question
How much the date matters is decided by what is being asked, because a stable fact and a changing treatment age at different rates.
Roles assigned instead of a winner
The closing says what each source is good for and where it should not be leaned on, which is more useful than a ranking.
Where marks go in NSG 660 Unit 3
Credibility papers lose points by grading appearance. A source dismissed because the page looked commercial, or accepted because it carried a professional logo, has reported a first impression and left the appraisal criterion empty. The second loss is the hierarchy recited but never applied: a paragraph naming levels of evidence, followed by four judgments that ignore them. Papers checking a publication date without opening the reference list miss sources that are recent and built on nothing. Treating age as a disqualification is the same error reversed, and it removes the older work a field still relies on. Comparisons in which all four sources are of one kind produce no contrast to reason about. An employer's internal guidance cannot be one of the four.

NSG 660 Unit 3 questions, answered
Does a source have to be peer reviewed to be usable?
Not for every purpose, and explaining why is part of the work. Professional guidance, government data and clinical guidelines are not peer reviewed in the journal sense and still carry weight for particular claims. What the comparison should refuse is a source whose authorship, funding or evidence cannot be established at all, and it should say which of the three is missing.
How recent does a source have to be?
It depends on the question rather than on a rule. A five year cut is a habit borrowed from search filters, and applying it to a question about anatomy or about a long settled intervention removes the best available work. Argue currency against what is being asked, and say when a field has moved enough that older evidence has been overtaken.
Can a source I found through a search engine be included?
Yes, and including one is often the point, since that is where a colleague or a patient starts. Read it against the same questions as the others and say what it would take for the page to be trustworthy. What matters is showing the difference in how the sources were built, not that every entry passes.
