Editorial standards

What we publish

We teach the arithmetic of IV medication math — dimensional analysis, unit conversions, infusion rates, bolus and dilution problems — and the habit of an independent double check. We write for nursing, pharmacy, and medical students, and for clinicians refreshing their skills.

Every worked case is fictional and labelled as fictional. Nothing here is clinical guidance: in real care, your institution’s protocols and pharmacy references govern.

Who writes

Articles are currently written and checked by one author at iAnesthesia LLC, the company that makes Drug Infusion, and are published under the company’s name. Every byline links to an author page that states the author’s relationship to the app.

Articles that work clinical calculations will carry a named author. The author page gives the credential, and any license or role, exactly as the author supplies them, and the author’s relationship to Drug Infusion.

Review

No article on this site has been reviewed by an independent clinical reviewer yet. Until one has, its byline says that it is written and checked by its author and not yet independently reviewed.

When a qualified reviewer, such as a nurse educator or a pharmacist, has checked an article, its byline names them, links to their author page, and gives the review date. We never name a reviewer who did not review the piece. Each article is due for another review 12 months after its last review, or after it was published if it has none.

How numbers are checked

We check the numbers in every worked example like this:

1. The build recomputes it. Worked calculations are written as chains of conversion factors. Before a page can go live, our build recomputes each chain exactly, with fractions rather than rounded decimals, and stops the release if the units do not cancel to the answer’s units or the result does not match the stated answer at its stated precision.
2. The author works it a second way. For example, a rate found by dimensional analysis is checked again with a formula.
3. A second person reworks it, when one is available. They solve the problems without seeing our answers. Until someone independent has, the byline says the article is not yet independently reviewed.

The build check proves that the arithmetic and the units agree. It does not judge whether a case is clinically realistic; that judgment is the author’s, and a reviewer’s when there is one.

Sources

Articles that state facts cite their sources in a references list, with the date each was accessed: medication-safety organizations such as ISMP and ECRI, open nursing textbooks and standard references, and DailyMed for any fact about a specific drug.

We link to these sources and paraphrase them; we do not reproduce their lists, test plans or other material. Citing an organization does not mean it has reviewed or approved our work, and we are not affiliated with any organization we cite.

What we never publish

• Dose ranges, starting or maximum doses, or treatment protocols.
• A calculator that turns a reader’s own numbers into a dose or a rate. Practice problems use fixed, fictional values.
• Real patient information, or a case presented as a real patient.
• Copy that casts the reader as someone treating a patient, such as “your patient” or “at the bedside.”
• Promises about speed or exam results, such as “instantly” or “walk in ready.”
• Testimonials, ratings or “trusted by” claims we cannot document, and no invented, AI-written or anonymous quotes.
• A “free trial.” There is none: the free features have no time limit, and Pro is a one-time purchase.
• Claims that an organization or exam body endorses us, or that our content meets its standards, such as “ISMP-compliant.”
• Articles produced in bulk or written to a word count.

How we use AI

Some articles are drafted or edited with help from AI tools. An article that used them says so in its byline: “AI tools helped draft this article.”

Whatever a tool drafts, a person is responsible for it. The author checks every statement against the cited sources, and every worked calculation goes through the same checks as any other. We do not use AI tools to invent quotes, reviewers, authors, credentials, or case details presented as real.

This site’s other pages, including this one, are also drafted with help from AI tools, and iAnesthesia LLC reads and approves each one before it goes live.

Corrections

Found an error? Email support@ianesthesia.org. We correct confirmed errors of fact, arithmetic, units or references in an article or practice problem. Within 7 days of finding one, we fix the page, show an updated date in its byline, and log the correction here with the date, the page and what changed. Edits to wording or layout that fix no error are not logged.

Conflicts of interest

iAnesthesia LLC makes and sells Drug Infusion, including its optional Pro purchase, and also writes the articles on this site. When an article mentions the app, it is the company pointing to its own product.

• Articles that teach an app feature say whether it is free or needs Pro.
• This site carries no advertising.
• We never offer anything in exchange for App Store ratings or reviews.
