1. The MD has ordered 250 units/1 hr through IV. The pharmacy sends an IV bag labeled Heparin 25,000 units/500 mL of D5W IV solution. Calculate the IV pump setting for mL/hr. Round your answer to the nearest whole number.

1. Order is for 50mg/1 hr. Med sent to the RN is 2g/100 mL Normal Saline. Calculate the mL/hr to set the pump. Round your answer to the nearest whole number.
1. MD order is 500 mL of 0.9% NaCl to infuse in 45 minutes. The drop factor listed on the IV tubing box is 15 gtt/mL. Calculate the number of drops per minute required to infuse the IV bolus. Round to the neatest whole number.
1. A dosage of 350 mg is ordered. The solution strength is 150 mg/2 mL. How many mLs are required for this dose?

1. Order: Ketorolac 100 mg IM every 12 hr PRN for pain

Available: Ketorolac 50 mg/mL. How many mL will you administer? Round to the nearest tenth.

1. MD orders 500 mL of Dextran to be infused over 24 hours. How many mL/hr should the IV pump be programmed for?

1. Mr. C who has peptic ulcer disease, has Pepcid 20 mg in 100 mL D5W ordered every 12 hr. The Pepcid is to be infused over 30 minutes. With a drop factor of 10 gtt/mL, how many drops per minute should be given?

1. Mrs. T has an order for 500 mL of 0.9% NaCl IV over 4 hours for Oliguria. The drop factor is 10 gtt/mL. How many gtt/min should be given?
1. A terminal patient has an order for Dilaudid at 0.5 mg/hr by continuous drip. Given a bag with a concentration of 20 mg Dilaudid in 100 mL of D5W, how many mL/hr should the IV pump be programmed at?

This can be calculated by:

Doctors order – 250 units of heparin/hr

Available - Heparin 25,000 units/500 mL of D5W IV solution.

To find the ml/hr use the equation,

ml/hr = Volume of IV fluid in ml ×   Units in dose

Total number of units in volume time/hr

= 500ml   × 250units

25000 units 1 hr

= 5ml/hr

This can be calculated by:

Order – 50mg/hr

Available dose is 2gm/100ml

Covert gm to mg,

1 gram is 1000 mg , Hence 2gm is 2000mg

ml = Dose ordered

Available dose

= 50mg ÷ 2000 mg × 100 ml

= 2.5 ml/hr

This can be calculated by:

Order - 500 mL of 0.9% NaCl to infuse in 45 minutes.

Drop factor – 15gtt/ml

To find the drops per minute,

Number of drops per minute = Total volume   × Drop factor

Time (in mints)

= 500 ml ÷ 45 mints × 15 gtt/m

= 166.66 = 167 drops/min

This can be calculated by:

Order is 350mg

Available dose is 150mg/2ml

To calculate the ml,

ml = Dose ordered × Quantity in ml

Available dose in mg

= 350 mg × 2ml

150 mg

= 4.66 = 4.7 ml
