NU504's Unit 3 record holds a PICO question on overnight earplugs and masks against ICU delirium, four sources searched with strings and counts, and a design profile of the survivors. Searches like "nu 504 unit 3 assignment example", "nu504 unit 3 sample" and "nu504 unit 3 example" land here.
What a finished NU504 Unit 3 question and search record looks like
Three pages plus an appendix. On page one the question appears in PICO form, naming CAM-ICU as the outcome measure while accepting the Intensive Care Delirium Screening Checklist, since trials use both. Page two is a compact search table covering PubMed, CINAHL, Cochrane CENTRAL for trials and ClinicalTrials.gov for registered studies, each with its final string, date and count in brackets. Screening appears as a four-box flow, from [486] records to [11] included. Page three is the part that sets this record apart: a profile table listing each included study with its design, its sample size, its delirium measure, and a yes or no on whether an effect estimate is reported with a confidence interval. The appendix gives full strings, and a note records [two] registered trials that finished without publishing results.
How a NU504 Unit 3 example is structured
The record is built to feed appraisal, so its order runs from question to evidence profile rather than stopping at a count. The question fixes the outcome measure first, because a search that mixes delirium screening tools produces studies whose results cannot later be compared directly, and the record says which tools it accepted. Searching a trials register is justified in a sentence: registered trials that never report results are a warning sign for publication bias, and the [two] found here are named so a later synthesis can mention them. Screening decisions are counted at each box. The profile table then turns [11] titles into something analytic: [five] randomized trials, [three] before-and-after studies, [two] cohorts and one systematic review, with only [six] reporting intervals. That tally predicts which studies will carry weight in the appraisal units that typically follow.
A question with its measure named
Each PICO element is stated, and the outcome line names the delirium tool, because results measured differently are hard to set side by side later.
Four sources, one table
PubMed, CINAHL, CENTRAL and a trials register each take one row with the final string, the search date and a count, bracketed, taken from the searcher's own run.
Why a registry was searched
Registered trials that finished without reporting results are listed by registration number, flagged as possible publication bias for the synthesis to weigh.
Screening in four boxes
Records identified, screened, assessed in full and included, each with a count and reasons for exclusion totaled beside the box.
The design profile
Every included study is tagged with design, sample size, delirium measure and whether its effect estimate comes with a confidence interval.
Where marks go in NU504 Unit 3
The commonest shortfall is a record that ends at the final count, as though finding studies were the goal, when NU504 prompts generally ask what the retained set can support. A question without a named outcome measure lets incomparable studies through and stores up trouble for the evidence table. Search strings reported only in part, or limits applied without saying so, make the counts impossible to judge. Omitting a trials register is a smaller loss but a telling one in a course about analysis, since unpublished trials skew what the literature seems to show. Design labels copied from abstracts are sometimes wrong, and a pretest-posttest study called a trial draws comment. Profiles that list designs but never note which studies report intervals miss the link to the statistics work that often follows.

NU504 Unit 3 questions, answered
Why search a trial registry as well as databases?
Because published literature leans toward positive findings. Trials registered on ClinicalTrials.gov or the WHO registry platform that finished years ago but never reported results may have found nothing, and their absence makes an intervention look better than it is. Listing them does not require appraising them; it lets the synthesis acknowledge that the visible evidence may be incomplete.
Does the profile table replace an evidence table?
No. It is a sorting step, done before any study is read closely, that shows what kinds of evidence the search produced and which studies report enough statistical detail to interpret. The full evidence table, usually a later assignment, adds findings, limitations and appraisal for each row. Keeping the profile short prevents the search record from turning into an early critique.
Can I use the sample's search strings for my own question?
The structure transfers; the terms rarely do. Each concept block has to be rebuilt from your own population and outcome, using the subject headings that the databases actually assign, and run on your library's platform. The sample shows how a finished record is laid out and what the profile table checks, and the counts you submit must come from your own search.
