**Types of Intravenous Fluids**• D5W = D5%W • D5S = D5 %0.9NS • D51/2NS = D5 %0.45NS • NS = 0.9%NS • ½NS = 0.45% NS**Intravenous Drip Factors**• Microdrip = 60 gtt/mL • Macrodrip need to check package • 10 gtt/mL • 15 gtt/mL • 20 gtt/ml • To calculate IV drip rates, must know this information**Electric Infusion Pumps**• Volume for infusion • Rate for infusion • Turn pump on**Intravenous Piggybacks on Electronic Infusion Pumps**• Secondary volume • Secondary rate • Turn pump on**Calculating Basic IV Drip Rates**• Number of milliliters to infuse x tubing factor = drops per minute or gtt/min number of minutes to infuse • When the order reads “hour,” convert to minutes by multiplying by 60 (60 minutes = 1 hour)**Calculating IV Drips for Infusion Pump**• Total number of milliliters ordered = mL/hour Number of hours to run**Question**Order: 1000 mL D5W at 120 mL/hour Available macrodrip 15 gtt/mL What is the drip factor in drops per minute? A. 30 B. 31 C. 32 D. 33**Answer**A. 30 • 120 mL × 15 gtt/mL = 30 gtt/min 60 minutes**Determining Hours an IV Will Run**• Number of milliliters ordered = Number of hours to run Number of milliliters per hour**Question**How many hours will 500 mL of D5½NS run at 125 mL/hour? A. 3 B. 4 C. 5 D. 6**Answer**B. 4 • Number of milliliters ordered = Number of hours to run Number of milliliters per hour • 500 mL = 4 hours 75 mL/hour**Choosing the Infusion Set**• Microdrip • IV administered over a long period • Small amount of fluid to be infused • Macrodrops per minute too few • Macrodrip • Order specifies a large amount of fluid over a short time • Microdrips per minute are too many, and counting the drip rate becomes too difficult**Adding Medications to IVs**• Check diluent and volume • Check dose and expiration date of reconstituted solution • Note whether IVPB should be refrigerated before use and remain at room temperature • Calculate the drip rate and record this information on IVPB label**Enteral Nutrition**• Used when patient cannot eat or cannot eat enough • Administered with a pump • Intermittent • Cyclic • Continuous
