Unit IV Math help!

(1) You must determine how many units per hour the patient is receiving.

7 mL/hour (infusion rate) x 25,000 units/250 mL (dose on hand) = 700 units/hour (current dose of Heparin that the patient is getting)

(2) Calculate the new hourly dose of Heparin (doctors order continuous IV Heparin as units/hour).

700 units + 500 units = 1200 units

(3) Determine the new rate for the IV pump for this new dose of Heparin (1200 units/hour) with an IV concentration of 25,000 units in 250 mL of D5W.

1200 units/hour (dose desired) x 250 mL/25,000 units (dose on hand) = 12 mL/hour (infusion rate)
