Databases, subject headings, limits, a screening count from [412] to [14] and a reason for every exclusion: the literature search summary NU298 asks for in Unit 3, on alarm fatigue. Searches like "nu 298 unit 3 assignment example", "nu298 unit 3 sample" and "nu298 unit 3 example" land here.
What a finished NU298 Unit 3 literature search summary looks like
About three pages with a flow diagram. A search table lists each database, the date searched, the terms and the limits. CINAHL Complete used its subject headings for alarms and monitoring combined with keywords such as alarm fatigue, nonactionable and electrode; PubMed used the MeSH heading Clinical Alarms with electrocardiography and monitoring terms, OR joining synonyms and the AND operator linking concepts. The Cochrane Library found no relevant review. Limits were English, adults and 2012 to [2024]. A PRISMA-style diagram follows: [412] records, [96] duplicates, [316] screened by title and abstract, [41] read in full, [14] included. An exclusions table gives the count behind each reason. Gray literature appears separately: The Joint Commission's alert and the AACN practice alert on managing alarms. A closing table sorts the fourteen studies by Johns Hopkins evidence level.
How a NU298 Unit 3 example is structured
Reproducibility is the organizing aim: a reader should be able to rerun the search and reach similar numbers. The table therefore records exact terms, operators and limits rather than describing them, and the date limit is explained as capturing work since alarm safety became a national priority. Each exclusion decision has a stated reason, and the contested ones get a paragraph. Intensive care studies were kept, because false alarms arise the same ways on telemetry units, loose leads and artifact, though at lower volume. Pediatric studies were excluded, since children's normal ranges make default-limit findings hard to transfer. Studies of pulse oximetry alone were cut to match the scope. Levels follow the Johns Hopkins scheme, and the summary admits the pattern: most sources sit at Levels III to V, observational studies and quality improvement projects, with few controlled designs. That imbalance is stated as a limitation of the field.
A table that can be rerun
Database, date searched, exact terms, Boolean operators and limits sit in one row each. Anyone repeating the search from the table should arrive near the same record counts.
Headings and keywords together
Controlled vocabulary catches indexed studies and keywords catch recent ones not yet indexed. The summary shows both for each database and explains why alarm fatigue was searched as a phrase.
Intensive care kept, pediatrics cut
False alarms arise the same way in intensive care and on telemetry units, so those studies stayed. Pediatric work went out because children's normal ranges make default-limit findings hard to carry over.
Gray literature counted separately
The sentinel event alert and the AACN practice alert are not research, but they shape practice. The summary lists them apart from the fourteen studies so the two kinds of evidence never blur.
Levels that lean low
Sorted by Johns Hopkins level, the included studies cluster at III to V. The summary states that pattern as a feature of the field and flags what it will mean for the strength of any recommendation.
Where marks go in NU298 Unit 3
A list of sources with no record of the search that produced them fails the unit's main criterion, and a reference list with no search record behind it usually earns a comment about method. Terms described loosely, searched for alarm fatigue, cannot be reproduced; exact strings and limits can. Exclusions made without reasons invite doubt about every inclusion. Evidence levels assigned without naming the scheme, or levels that do not match the hierarchy cited, cost accuracy points. Treating practice alerts or vendor white papers as research blurs categories graders watch closely. A search confined to one database, or to free full text, suggests convenience over coverage. Missing counts leave the reader unable to judge the search's reach, and a summary that hides the low level of most evidence overstates the project's footing.

NU298 Unit 3 questions, answered
What is the Johns Hopkins evidence hierarchy?
Part of the Johns Hopkins Nursing Evidence-Based Practice model. Research evidence runs from Level I, randomized controlled trials and systematic reviews of them, through Level II, quasi-experimental studies, to Level III, nonexperimental and qualitative work. Non-research evidence sits at Level IV, clinical practice guidelines and consensus panels, and Level V, literature reviews, quality improvement projects and expert opinion. Each source is also graded for quality, A to C.
Which databases should a nursing capstone search use?
CINAHL is the core nursing database, and PubMed, which covers MEDLINE, adds the wider biomedical literature. The Cochrane Library is worth checking for systematic reviews. Many programs expect at least two databases. Record the date of each search, since results change over time. Your library may also offer a librarian consultation, which often improves the search terms considerably.
What is the Melnyk hierarchy, and how does it differ?
Melnyk and Fineout-Overholt describe seven levels, from Level I, systematic reviews and meta-analyses of randomized trials, down to Level VII, the opinion of authorities or expert committees. Randomized trials sit at Level II, controlled trials without randomization at III, cohort and case-control studies at IV, and reviews of descriptive or qualitative studies at V. Use whichever scheme your course names, consistently.
