50) Prevention: The importance of checking a medication label at least three times to verify supply dosage cannot be
overemphasized. It is also important NEVER to assume that the supply dosage is the same as a supply dosage used to
calculate previously. Always read the label carefully. Writing the calculation down will also help improve accuracy.

Do not exceed 50 mg/1 min. The .
Administer at 1 mL/1 min or 0.25 mL/15 seconds.
Either syringe could measure the amount, but the
1 mL syringe will provide greater control for pushing
medication at the rate recommended.

Measure the 18.8 mL precisely to add to the IV PB
bag. But for the drip-rate calculation, such a precise
measurement is not necessary. You may round the
18.8 mL to 19 mL for the computation of the drip
rate only.
