A practice exam that behaves like the real one: you choose the problem types and the length, answers are typed rather than picked from a list, the clock runs if you want it to, and everything is marked at the end against your program's pass mark. Each attempt draws new questions, so you can retake it as often as you need.
Last updated · How pages are checked
Pick the problem types your exam covers, set the length and the pass mark your program uses, and work every question on paper before you type the answer. When you finish, read the working for each miss and name the step that broke: a unit conversion, the setup, or the rounding. Then practice that type before your next attempt.
Earlier versions of this quiz used multiple choice. It was easier than a real dosage exam, because four options let you work backwards from the answers and rule out the silly ones. Most school med-math tests give you a blank line and a calculator, so this one does too. It will feel harder. That is the point.
Answers are checked the way an instructor would check them. The right number with the wrong rounding is marked wrong, with a note saying so. A miss caused by a classic slip, like using pounds as kilograms or forgetting to divide a daily dose, is named in the review.
| Category | Typical question | Practice it |
|---|---|---|
| Tablets | Order 0.15 mg, tablets 75 mcg: how many? | Tablet practice |
| Liquids and injections | Order 650 mg, solution 160 mg/5 mL: how many mL? | Liquid practice |
| Weight-based | 30 mg/kg/day divided q8h for a 33 lb child | Weight-based practice |
| Pediatric safe dose, BSA | Is 250 mg q8h within 25–50 mg/kg/day for 20 kg? | Pediatric practice |
| IV flow rate, infusion time | 100 mL over 30 min: pump rate? | IV flow practice |
| IV drip rate | 1,000 mL over 8 hr, 15 gtt/mL: gtt/min? | Drip rate practice |
| Reconstitution | Order 500 mg; after mixing 250 mg/mL: mL? | Reconstitution practice |
| Heparin and insulin | 1,200 units/hr from 25,000 units/500 mL: mL/hr? | Heparin & insulin practice |
| Critical care drips | Dopamine 5 mcg/kg/min, 80 kg, 1,600 mcg/mL: mL/hr? | Critical care practice |
If the setup is what trips you up, the three calculation methods are compared side by side with the same problems solved each way. If it is conversions, the drug unit converter has the full tables.
Most nursing programs set the bar for medication calculation exams at 90% or higher, and a fair number require 100%. That sounds harsh until you consider what the exam stands in for: in practice there is no partial credit on a dose. If you are scoring in the 70s here, that is not a near miss. It is a signal to keep going until the method is automatic.
The good news is that med math is mostly pattern recognition. There are about ten problem shapes, and once each one is familiar the arithmetic stops being the hard part. Use the results screen: it groups your misses by type and links straight to the practice for each one.
The default timer gives 90 seconds per question, so a 20-question exam has 30 minutes. Some school tests are more generous (one community college's practice math exam allows 60 minutes for 20 questions), so practicing at 90 seconds leaves you a margin on the day. Switch it off while you are still learning, then turn it on in the week before your exam.
Answers are marked with the rounding rules you have saved on the practice hub: pump rates to the tenth or whole number, half tablets allowed or not, heparin units and converted weights rounded your program's way. Set them to match your program before you start.
Open "build your own exam", choose the problem types, length, timer and pass mark, and press "Create a class link". Everyone who opens that link gets the same questions in the same order, marked by the rounding rules you had saved when you made it. It works well as homework, as a warm-up before a competency test, or as a retake that matches the original.
There are no accounts and no gradebook. Each student's answers are marked in their own browser, and the results screen gives them a single result line, with the exam code, score, percentage and time, to copy into an email or your learning platform. The same questions can be printed from the worksheet generator, with an answer key, for students who work better on paper.
This page is a free practice exam with new randomized questions every attempt, a worked solution for every question at the end, and no sign-up. For untimed practice with instant feedback, start on the practice hub.
Oral tablet and liquid doses, injectable volumes, weight-based mg/kg dosing, IV flow rates in mL/hr, drip rates in gtt/min, conversions, and safe-dose checks. Most can be solved with desired over have, ratio and proportion, or dimensional analysis.
Many programs require 90% or higher on medication calculation exams, and some require 100%, because dosing errors carry direct patient risk. Set the pass mark to match your program, and treat anything below it as a signal to keep practising.
Yes. Each attempt draws new randomized questions from the types you select. The exam code on the results screen lets you retake exactly the same set if you want to compare scores.
Yes. Build a custom exam and press "Create a class link". Everyone who opens the link gets the same questions with the same rounding rules. Scores are not collected by the site: each student copies a result line from the results screen and sends it to you.
