Nursing programs test dosage calculation, and on a ward a misplaced decimal point is a medication error.DoseDrill gives nursing students problems to work by dimensional analysis, a daily set for free, with every step of the setup shown.
What you can practise
There are 8 kinds of problem: tablets and oral liquids, IV drip rates in drops per minute, pump rates in mL per hour, infusion times, weight-based doses, reconstitution of powders and weight-based infusions. A separate page covers safe notation: the leading-zero and trailing-zero rules that prevent ten-fold dosing errors.
Where the problems come from
Each problem is generated by this site's own code from a numeric seed, so the same seed always gives the same problem, and the answer and its working come from the site's solver rather than from an answer key. The conversion factors and formulas are the standard ones taught in dosage calculation; no question is taken from a published bank, textbook or exam.
The drug names and strengths in the problems are kept to marketed strengths and plausible adult doses so the numbers look like real orders. They are teaching scaffolding, not a prescribing reference, and the data file says so in as many words.
Who keeps it
One independent developer builds and runs DoseDrill. The same developer runs a handful of other study sites for health students: AnatoMemory, LabVals, PetriKey and ChartCall.
All 8 guides are signed by DoseDrill itself, so there is no individual byline, and the author listed in their structured data is the site's organization. No nursing, pharmacy or medical credential is claimed.
What DoseDrill is not
It is a study tool, not a clinical one. Never use it to calculate or give medication to a real patient. The rounding rules a guide describes are the ones taught for coursework, and your facility's policy, its pharmacy, current drug references and an independent double check are what govern real doses.
