150 dosage calculation practice problems for nursing students, each with a step-by-step solution: formula, substitution, result with units. A how-to page, two worked examples (ratio and formula methods), ruled working space under every problem, and full answers. A4 and US Letter versions are identical; dosage-problems.json holds the same set for flashcard apps.

Sections: basic conversions (20), oral tablets (30), oral liquids (40), pediatric mg/kg doses (25), IV rates (20), infusion time (15). Each solution prints its rounding rule, and a problem counts as correct only when number and units match.

Fundamentals courses commonly require a 90 percent score, so treat 135 of 150 as your passing line. Practice material only: verify against institutional protocols and a licensed professional.
