hi, meespo, and welcome to allnurses!

the patient has a continuous heparin infusion. the nurse has been given credit for 325 ml at 0700. the order is for ns 500ml with 15,000 units of heparin in it to infuse at 600 unit/hour. the iv has pedi-drip tubing. **calculate the flow rate**.

**dose desired: **600 units/ hour

**dose on hand:** 15,000 units of heparin in 500 ml of normal saline

**drop factor of iv tubing: **60 drops/ml (pediatric tubing

**conversion factor: **60 minutes/1 hour

the information about the nurse being given credit for 325 ml already being given to the patient is not important to determine the information that the problem is asking for. it's a red herring. to calculate the flow rate, you want to determine the number of

**drops/minute**:

**600 units/1 hour** (dose desired) **x 500 ml/15,000 units** (dose on hand) **x 60 gtts/1 ml** (drop factor of pediatric iv tubing) **x 1 hour/60 minutes** (conversion factor) **= **__20 gtts/minute__ flow rate
