For children, heparin sodium is administered by intermittent IV infusion in a range of 65 to 80 units/kg of body weight every 4 hrs. For a $70-\mathrm{lb}$ child, calculate the range, in $\mathrm{mL}$, of a heparin sodium injection containing 5000 units/ $\mathrm{mL}$ to be administered daily.

Key Concepts

Repeated Dosage Calculation

When a medication is administered at regular intervals throughout the day, it is important to calculate the total daily dose by multiplying the dose per interval by the number of intervals. This concept helps in managing the cumulative dosage over a specific period.

Concentration and Volume Conversion

This concept involves using the drug concentration, expressed as units per milliliter, to convert the calculated dose in units to the corresponding volume in milliliters. It connects the dosing calculations with the practical preparation and administration of the medication.

Weight-Based Dosing

Weight-based dosing calculates the drug amount required based on the child's weight. This approach ensures the administered dose is appropriate for the individual's body mass, enhancing both the effectiveness and safety of the therapy.

Unit Conversion

This concept involves converting measurements from one unit to another to ensure that all quantities used in calculations are consistent. In medical dosing, converting weight from pounds to kilograms is essential because dosages are frequently prescribed on a per kilogram basis.
