I.V. Drug Calculations Flashcards

A comprehensive vocabulary and formula set for intravenous drug dosage calculations and unit conversions.

D

Desired dose

H

Amount on hand

V

Volume

Basic dosage calculation formula

$$\frac{D}{H} \times V = \text{Dose}$$

I.V. drips in mcg/minute calculation factors

$$\frac{\text{mg}}{\text{mL}} \times \frac{1,000\,\text{meg}}{1\,\text{hour}} \times \frac{1\,\text{mL}}{60\,\text{minute}} = \text{mcg/minute}$$

Weight-based I.V. drip conversion

Divide by kg to get $\text{mcg/kg/minute}$

I.V. drips in unit per hour formula

$$\frac{D}{H} \times V = \text{units/hour}$$

Alternative unit per hour dose calculation

$$\#\,\text{mL} \times \text{units/mL} = \text{dose}$$
