Fitting RxNorm to medication reconciliation at admission, the HI530 Unit 4 analysis names which RxNorm concept level each workflow step needs and why package codes fall short. Searches like "hi 530 unit 4 assignment example", "hi530 unit 4 sample" and "hi530 unit 4 example" land here.
What a finished HI530 Unit 4 use case analysis looks like
Five pages built on a swimlane diagram of the reconciliation workflow, with lanes for the patient interview, the pharmacy fill feed, the admitting clinician and the pharmacist. Four steps are identified: collect, normalize, compare and decide. A step table follows, listing for each the data that arrives, its current code if any, and the question the step must answer. The fill feed arrives with NDCs, which identify a specific package from a specific labeler. The home list arrives as free text, such as a brand name and a strength the patient remembers. Comparison needs both reduced to the clinical drug, ingredient plus strength plus dose form, which RxNorm represents at its semantic clinical drug level. A composite example follows two entries for one drug under different brands, matching at that level and differing at the package level.
How a HI530 Unit 4 example is structured
The analysis is ordered by the workflow rather than by the vocabulary, so the case for RxNorm grows out of what each step demands. Steps are described first without naming any code system, stating only the question each must answer: is this the same drug, at the same strength, in the same form? Candidate vocabularies are introduced after that, NDC, RxNorm, and free text with local codes, and tested against each step in a fit table. RxNorm wins the comparison step because its clinical drug level matches the question exactly, while NDC fails by being too specific and free text by being inconsistent. The paper then asks what level suits the decision step, where an allergy or duplicate-therapy check may need ingredient or drug class instead. Limitations close the body: supplements the patient reports may lack an RxNorm concept, and the paper says how those are handled.
Four steps before any vocabulary
Collect, normalize, compare and decide are each defined by the question they answer, so the vocabulary choice follows from requirements rather than reputation.
Package codes on the fill feed
NDCs identify a labeler's package, so two fills of the same drug from different manufacturers look unrelated until they are normalized.
The clinical drug level
Ingredient, strength and dose form together answer the comparison question, and RxNorm's semantic clinical drug concept represents exactly that combination.
Different levels for different checks
Allergy and duplicate-therapy checks may work at ingredient or class level, so the analysis names which level each downstream check reads.
What the vocabulary misses
Some patient-reported supplements lack a concept, and the analysis records them as free text flagged for pharmacist review rather than dropping them.
Where marks go in HI530 Unit 4
Use case papers are usually graded on fit, and recommending a vocabulary for its adoption or reputation, without tying it to a step in the workflow, earns little under that criterion. Workflows described too vaguely to test against, a single box labeled reconcile, give the fit argument nothing to stand on. Treating NDC and RxNorm as interchangeable is the most common factual error, since one identifies packages and the other normalizes clinical meaning. Recommending one concept level for every step misses that comparison and allergy checking ask different questions. Papers that ignore free-text home lists assume the hard part away. Limitations omitted, especially items outside the vocabulary's coverage, weaken the realism graders look for. Real product names paired with dosing that could read as clinical advice also draw comments, which is why the example stays composite.

HI530 Unit 4 questions, answered
What is the difference between an NDC and an RxNorm code?
An NDC identifies a specific product package from a specific labeler, so the same drug from two manufacturers carries different NDCs. RxNorm normalizes drugs to their clinical meaning, ingredient, strength and dose form, and links many NDCs to one concept. Reconciliation compares clinical meaning, which is why the analysis translates package codes into RxNorm before comparing anything.
Could SNOMED CT be used for medications instead?
SNOMED CT includes medicinal product concepts, and some organizations use them, but RxNorm is the vocabulary named for medications in most U.S. interoperability requirements and is linked to pharmacy NDCs. The analysis mentions SNOMED CT as an alternative and explains why RxNorm fits the U.S. reconciliation workflow better. A different setting in your prompt could change the fit.
Does the paper need a workflow diagram?
Most use case prompts reward a diagram, since it lays out the steps the vocabulary has to serve. A swimlane format is common since it separates who does what, but a simple flowchart can work if the steps are labeled. The sample includes a diagram described in text and laid out so it can be redrawn in whatever tool your section uses.
