⚠️ Educational tool — not medical advice
This generator produces randomized practice problems for nursing students and NCLEX review. It is not a substitute for professional medical guidance, and dosing errors can be harmful or fatal. Never use it to determine a real medication dose — always follow prescriber instructions, facility policy, and confirm with a pharmacist or physician.
NCLEX Dosage Calculation Practice
Generate randomized med-math problems — oral doses, liquid doses, IV pump rates, drip rates, weight-based dosing, and unit conversions — with step-by-step dimensional analysis solutions and a printable worksheet.

Core formulas (dimensional analysis)
| Type | Formula | Example |
|---|---|---|
| Tablet / oral | D ÷ H × Q | 500 mg ÷ (250 mg/tab) × 1 = 2 tablets |
| Oral liquid | D ÷ H × Q (mL) | 500 mg ÷ (250 mg/5 mL) × 5 = 10 mL |
| IV pump rate | Volume ÷ Hours | 1,000 mL ÷ 8 hr = 125 mL/hr |
| IV drip rate | (mL × gtt/mL) ÷ min | (500 × 15) ÷ 240 = 31 gtt/min |
| Weight-based | kg × mg/kg | 70 kg × 2 mg/kg = 140 mg |
| lb → kg | lb ÷ 2.2 | 154 lb ÷ 2.2 = 70 kg |
These are standard formulas taught in US nursing programs and NCLEX prep. Always round per facility policy and verify with a second check.
Frequently Asked Questions
How do I use dimensional analysis for dosage calculations?
Set up the problem so units cancel, leaving only the unit you need. Example: 500 mg ÷ (250 mg/tablet) × 1 tablet = 2 tablets. Every practice problem shows its dimensional-analysis steps so you can see exactly how the units cancel.
What formulas does the NCLEX test for med math?
The core ones: Desired ÷ Have × Quantity (D/H×Q) for tablets and oral liquids; total volume ÷ hours for IV pump rate (mL/hr); (volume × drop factor) ÷ minutes for drip rate (gtt/min); weight × mg/kg for weight-based dosing; and metric conversions (mg↔mcg, lb↔kg).
Can I print a practice worksheet?
Yes — the "Print worksheet" button generates a clean PDF-ready worksheet with a name/date line, work space, and an optional answer key. Perfect for study groups and NCLEX review.
Is this a substitute for clinical training?
No. This generator is an educational study aid. Medication administration always requires clinical judgment, verification with a second nurse where policy requires, and confirmation with a pharmacist. Never use it to set a real dose.
