Med dosage formula

Desired dose/ On hand X quantity

If the volume is more than 1ml

Round to the nearest tenth place

1.45ml —-to 1.5ml

1.43ml——to 1.4 ml

If the volume is less than 1ml round to the nearest hundredth

0.656 ml is rounded to 0.66 ml

0.644 ml is rounded to 0.64 ml

0.62 ml is rounded to 0.62 ml

Do all your rounding at the

End of the problem

In examsoft only enter the

numerical data not the unit

Ex) 0.5 not 0.5ml
