The Question in Searchable Form
The first module compared five studies on how parents measure children's liquid medicines, prompted by a community health center pharmacy manager's proposal to print doses in milliliters only, hand families an oral syringe whenever a liquid is filled, and counsel parents with picture-based instruction sheets. That module relied on sources already known to the team. This module searches systematically for the wider literature.
A searchable question needs defined parts. Written in the PICO format, the question is: among parents and other caregivers of children prescribed liquid medicines (population), do oral syringes, milliliter-only labels or pictogram-based instructions (interventions), compared with dosing cups, teaspoon units or text-only instructions (comparison), reduce dosing errors (outcome)? Each part becomes a group of search terms, and the groups are combined so that a record must mention all of them.
The Search
The search was run in PubMed at the end of September 2026. Terms were limited to titles and abstracts to keep the results focused: ("dosing error" OR "medication error") AND liquid AND (parent OR caregiver) AND (syringe OR cup OR pictogram OR milliliter OR teaspoon). The asterisk retrieves word endings, so parent finds parents and parental. The search returned 29 records, 28 of them published from 2004 onward.
The narrow string was a deliberate choice. A broader search on medication errors in children returns thousands of records, most about hospital prescribing, which does not answer a question about what parents do at home. The cost of narrowing is that relevant studies that use different words, such as dose measurement or administration accuracy, may be missed. For that reason, the bibliographies of the included papers were also combed, which is how one additional trial described later was confirmed as relevant.
Screening
Each title and abstract was held against two tests for inclusion: the study measured how accurately parents or caregivers dosed liquid medicines, and it tested or compared a dosing tool, a unit of measurement or a form of instruction. Ten records were excluded at this stage: two surveys of pharmacists' or prescribers' practices, four workshop reports, commentaries or professional recommendations, one poisoning case report, one evaluation of devices packaged with medicines that did not involve parents, and two comparisons of specific drug formulations. Of the 19 remaining records, eight tested or compared the three proposed changes in U.S. settings or synthesized studies that did. These eight are summarized below, since they speak most directly to a U.S. community clinic. Studies from other countries were set aside for this purpose, not because they were weak but because packaging, labeling rules and dosing tools differ.
Dosing Tools
Four studies addressed tools. Yin et al. (2010) observed 302 parents at a public hospital pediatric clinic measuring a 5-mL dose with six instruments: only 30.5% dosed accurately with a cup that had printed markings, compared with more than 85% with the droppers, dosing spoon and oral syringes, and limited health literacy was independently associated with errors. Yin et al. (2016), randomizing 2,110 parents in three clinics, found cups associated with far higher odds of error than syringes, especially for small doses. Yin et al. (2017), in a randomized experiment with 491 parents, added a refinement: errors were fewest when the syringe was matched to the dose, a 5-mL syringe for a 2-mL dose and a 10-mL syringe for a 7.5-mL dose, so that parents did not have to fill a tool twice or read tiny markings on a large one. The evidence does not say to give every family a syringe; it says to give every family the right syringe.
Units and Pictograms
The same 2017 experiment tested labels and instructions. Labels showing milliliters and teaspoons together were associated with more errors than milliliter-only labels, and parents given text-only instructions made more large errors, more than twice the intended dose, than those given text with pictograms. A systematic review by Chan et al. (2015) found five experimental studies of pictorial aids for liquid medicines with 962 participants, four hospital based and one community based, and concluded that pictograms reduced dosing errors and improved comprehension, recall and adherence, particularly when combined with verbal counseling. The reviewers cautioned that the evidence was limited by the small number of studies and variable quality.
Studies in Everyday Care
Two studies tested combined approaches in routine care, which is closest to the pharmacy manager's situation. Carroll et al. (2024) randomized 198 caregivers of young children being discharged from a children's hospital with a new liquid medicine to either standard counseling or a bundle of a pictogram-based instruction sheet, teach-back and a show-back demonstration with a syringe. Judged from photographs of filled syringes that caregivers sent from home, 30.4% of the intervention group measured an incorrect dose compared with 54.2% of the standard group. Cullen et al. (2022), in a resident-led quality improvement project at an outpatient pediatric clinic, raised the share of caregivers with adequate understanding of liquid acetaminophen at the two-month visit from 39.8% to 74% across 636 caregivers; the most effective steps were English and Spanish pictograms and dose-marked oral syringes, combined with teach-back.
Limits of This Search
The search has limits that a reader should weigh. It used one database. PubMed indexes most medical and pediatric journals, but CINAHL would add nursing and allied health studies, and pharmacy journals that report dispensing projects may be indexed in neither. Only one person screened the records, so the judgment about what counted as testing a tool or an instruction was never checked by a second reviewer, as it would be in a formal systematic review. Titles and abstracts can also mislead: a study whose abstract mentions dosing accuracy only briefly might contain useful comparisons that screening missed. Finally, the search found published studies only. Health systems that tried syringes or pictograms and saw no change may never have written it up, which would make the literature look more favorable than practice has been. These weaknesses would not flip what the studies found, but taken together they are a reason to measure results locally rather than assume them.
What the Literature Says and What It Lacks
Across designs and settings, the eight studies agree: syringes matched to the dose outperform cups, milliliter-only labels reduce confusion, and pictograms combined with counseling improve accuracy. The strongest real-world evidence comes from a randomized trial at hospital discharge and a quality improvement project in a primary care clinic, and both used the three elements together.
The literature also has clear gaps. Most studies come from one research group in large urban academic settings, which raises questions about how well the findings transfer to a community pharmacy. Few measured outcomes beyond observed dosing, such as return visits or harm. None examined a pharmacy, rather than a clinic or hospital, as the place where the change is made. The next module will appraise one study in depth to judge how much weight its findings can bear.

Reading the RES 4353 Module 2 instructions
In RES 4353 Module 2, you are generally asked to find and summarize research on a health question. Most prompts ask you to state the question clearly, often in PICO form, choose databases, record your search terms and limits, screen the results against inclusion criteria and summarize what the relevant studies found. Some versions require a table of studies with design, sample and findings; others ask for a narrative synthesis or an annotated bibliography. Graders expect the search to be described well enough that someone else could repeat it. You may use PubMed, CINAHL or the ACE library databases. Check Canvas for the number of studies required and whether they must be published within a set number of years.
How the RES 4353 Module 2 example is put together
The example first restates the practical question and converts it into PICO form, showing how each part becomes a group of search terms. The search section gives the database, date and exact string, and explains why the search was kept narrow. Screening is reported with counts and reasons for every exclusion. The included studies are then grouped by topic, tools, then units and pictograms, then studies in everyday care, with designs, samples and key numbers for each. A systematic review's own caution is reported rather than dropped. The final section states what the studies agree on and names three gaps, one research group, urban academic settings and few real-world outcomes, before pointing to the next module.
Reading the RES 4353 Module 2 rubric
Rubrics for this assignment usually weigh the search process, the quality of the summary and the synthesis. The search criterion rewards a clear question, documented terms and databases, and stated inclusion criteria. Graders often deduct points when the reader cannot tell how studies were found or chosen. The summary criterion looks for accurate reporting of each study's design, sample and findings, not just its conclusion. Synthesis earns the highest marks when the paper shows where studies agree, where they differ and what is missing. Currency and relevance of sources matter in most sections. Clear organization and APA 7 citations and references complete the score.
RES 4353 Module 2 help from the desk
Literature papers slip when they list studies one after another, each with a paragraph, and never say what they show together. Another frequent problem is an undocumented search, which leaves the grader unable to judge whether important studies were missed. Students also report conclusions without numbers or designs, which hides how strong the evidence is. Keep your search string exactly as run, and note the date. Say why you excluded what you excluded. Group studies by what they tested rather than by author. Name at least one gap. If your question concerns fall prevention teaching, vaccine reminders or food labels instead, tell us the topic and paste in the assignment wording, and we can build a Module 2 search around it.

RES 4353 Module 2 questions, answered
What does RES4353 Module 2 usually ask for?
The second RES4353 module often asks you to search the research literature on a health question, document how you searched and screened, and summarize what the studies found and where the evidence falls short. Your classroom's instructions decide the question and databases.
What is a PICO question?
A way of structuring a clinical question by population, intervention, comparison and outcome, which also gives you the groups of terms to combine in a database search.
How do you document a literature search?
Report the database, the date, the exact search string, any limits, the number of records found, and how many were excluded at each stage and why.
Where can I find a free RES 4353 Module 2 sample paper?
You can read the full paper on this page: the Module 2 search and summary on syringes, milliliter labels and pictograms for parents' liquid medicine dosing, with the exact PubMed string, screening counts and eight studies summarized.
Should a literature summary mention gaps?
Yes. Identifying what the studies do not cover, such as settings, populations or outcomes, is as important as reporting what they found.
