Nursing & Med-Math
Nursing med-math — dosage, IV drip and flow rates, weight-based doses, and clinical formulas.
18 tools
Dosage Calculation
How much to give from the dose ordered and the strength on hand.
IV Drip Rate
Drops per minute for a gravity infusion from volume, time, and drop factor.
IV Flow Rate
Millilitres per hour to program into an infusion pump.
Infusion Time
How long a bag will take to run and when it finishes.
Weight-Based Dosage
Daily and per-dose amounts from a mg/kg order and body weight.
Paediatric Safe Dose
Check an ordered dose against the safe mg/kg/day range.
Reconstitution
Concentration after adding diluent, and the volume to draw up.
Heparin Drip Rate
Bolus, units per hour, and pump rate for a weight-based heparin order.
Creatinine Clearance
Estimate CrCl in mL/min for renal dose adjustment.
eGFR Calculator
Estimated GFR and CKD stage from serum creatinine.
Anion Gap
Serum anion gap, with or without potassium, corrected for albumin.
Corrected Sodium
Adjust measured sodium for a raised glucose — Katz and Hillier.
Corrected Calcium
Albumin-corrected serum calcium in mg/dL or mmol/L.
mEq ↔ mmol ↔ mg
Convert electrolyte amounts using molar mass and valence.
Mean Arterial Pressure
MAP from systolic and diastolic, with pulse pressure.
Glasgow Coma Scale
Score eye, verbal and motor response out of 15.
Apgar Score
Score the five newborn signs at 1 and 5 minutes.
Parkland Formula
Burn fluid for the first 24 hours, with a Rule of Nines helper.
About nursing & med-math tools
The med-math nursing and pharmacy students are examined on — desired-over-have dosage, IV drip rates in gtt/min, pump flow rates in mL/hr, infusion times, weight-based and paediatric safe-dose ranges, reconstitution, heparin drips, and clinical formulas such as Cockcroft-Gault creatinine clearance and the anion gap. Every tool shows the dimensional analysis step by step. These are study aids for practising calculations, not medical advice — clinical dosing must be verified by a qualified professional against local protocol.
