NurseCalc: 40+ Clinical Calculators for Nurses and Allied Health

Clinical calculations are a constant part of nursing practice: drip rates, weight-based dosing, clinical scoring tools. Doing these on paper or hunting through reference books wastes time. NurseCalc is a free Android app that puts all of them in one place, with step-by-step formulas so you understand every result.

What NurseCalc Covers

IV and Infusion Calculators

• IV drip rate — volume, time, and drop factor; calculates drops per minute or mL/hr
• mcg/kg/min infusions — for vasoactive and critical care drugs where dose changes require immediate recalculation
• Titration calculator — adjust dose and see the new rate without starting from scratch
• TPN calculator — total parenteral nutrition macronutrient and fluid targets
• Maintenance fluids — Holliday-Segar method for paediatric and adult maintenance rates

Clinical Scoring Tools

Each scoring tool shows the individual items and their weights, so you score correctly rather than guessing:

• GCS (Glasgow Coma Scale) — Eye, Verbal, Motor responses with interpretation of the total score
• Braden Scale — six subscales for pressure injury risk assessment
• NEWS (National Early Warning Score) — physiological parameters with colour-coded risk banding
• APGAR Score — neonatal assessment at 1, 5, and 10 minutes
• CURB-65 — community-acquired pneumonia severity and admission decision guide
• Wells Score — DVT and PE pre-test probability

Unit Converters

Temperature, weight (kg/lb/oz/stone), volume (mL/L/oz/tsp/tbsp), and length (cm/in/ft) — all in one screen. No switching between apps.

Step-by-Step Formulas

Every calculator shows the formula and the calculation steps, not just the answer. This serves two purposes: you can verify the result makes clinical sense, and students see the working so they learn the formula, not just get an answer.

Works Offline

All calculations run locally — no internet required. Patient data never leaves your device. NurseCalc has no server component and no analytics.

For educational reference only. Always verify results against your institution's clinical protocols and consult current drug references for dosing.
