  1. HLTH 1210/LPN-CIV Calculation Practice Problems II Manual IV Flow Rate Formula: volume of infusion (in mL) x drop factor = Flow rate time of infusion (in minutes) (in gtt/min) Electronic IV Flow Rate Formula: total milliliters (mL) = Flow rate total hours (h) (in mL/h)

  2. Practice Problems (cont’d) Ratio/Proportion Formula: Cross-Multiply and Solve for “X” = =

  3. Practice Problems (cont’d) • The physician orders D5W IV at 125 mL/h. The infusion set is calibrated for a drop factor of 10gtt/mL. Calculate the IV flow rate in gtt/min.

  4. Practice Problems (cont’d) 2) Order: Lactated Ringer’s IV at 150mL/h. The drop factor is 15gtt/mL.

  5. Practice Problems (cont’d) 3) Order: Ampicillan 500mg IV in 100mL of NS, infuse over 45 min.

  6. Practice Problems (cont’d) 4) You receive a physician’s order for D5W 250mL IV over the next 2 hours by infusion pump. What is the mL/h?

  7. Practice Problems (cont’d) 5) Order: Ampicillan 500mg IV in 50mL D5 ½ NS in 30 minutes by IV pump. What is the mL/h?

  8. Practice Problems (cont’d) 6) Order: NS 1,800mL IV to infuse in 15 hours by infusion pump. Calculate the flow rate.

  9. Practice Problems (cont’d) 7) Order: Cefazolin 0.5g in 100mL D5W IV Piggyback to run over 30 minutes. Drop factor 20gtt/mL. What is the flow rate in gtt/min?

  10. Practice Problems (cont’d) 8) Order: Ancef 1g in 100mL D5W IV Piggyback to be infused over 45 minutes. Drop factor 60gtt/mL. What is the flow rate in gtt/min?

  11. Practice Problems (cont’d) 9) Order: 50mL IV PB antibiotic solution to infuse in 30 minutes. Drop factor 60gtt/mL. What is the flow rate in gtt/min?

  12. Practice Problems (cont’d) 10) You receive an order for D5W 1,000mL IV to infuse at 60mL/h to begin at 0600. At what time will this IV be complete?

  13. Practice Problems (cont’d) 11) You receive an order for Lactated Ringer’s (LR) solution 1,000mL IV to run at 125mL/h. How long will this IV last?

  14. Practice Problems (cont’d) 12) Order: D5W 1,000mL IV per 24 hours. Drop factor 60gtt/mL. What is the flow rate in gtt/min?

  15. Practice Problems (cont’d) 13) You receive an order for D5W 500mL with heparin 25,000 units IV at 850 units per hour. Calculate the flow rate in mL/h.

  16. Practice Problems (cont’d) 14) Order: Dobutamine 250mg IV in 250mL D5W to infuse at 5mcg/kg/min. Client’s weight is 80kg. Calculate the flow rate per infusion pump.

  17. Practice Problems (cont’d) 15) Order: Lidocaine 2g in 500mL D5W IV to run at 4mg/min. Calculate the flow rate per infusion pump.
