• Need some help with dosage calculations. Imt aking a 500 question test and these are the only ones i can't answer. Please help. 1.An IV piggyback of 100 mL is to be administered over 40 minutes. The drop factor is 10 gtt/mL. How many drops per minute will be infused? 2. The client is receiving an infusion of 500 mL of D5W at the rate of 25 gtt/min. The drop factor is 12 gtt/mL. How many milliliters per hour is the client receiving? 3. You enter a client s room and note that 600 mL is left in the IV bottle. The client is receiving 25 gtt/min, and the drop factor of your tubing is 15 gtt/mL. How many hours will the IV last? 4. Order: Versed 3 mg IV q2h prn for agitation Available: Versed 5 mg/mL How many milliliters of Versed should be administered? 5. The order calls for the infusion of 500 mL of D5W with aminophylline 1 g. The drop factor is 60 gtt/mL. Calculate the flow rate in drops per minute if the client is to receive 0.6 mg/kg/hr by way of continuous infusion. The client weighs 50 kg. 6. The client is to receive a 1 mg/min infusion of lidocaine hydrochloride. The drop factor is 60 gtt/mL. The order calls for the addition of 750 mg of lidocaine hydrochloride to 500 mL of D5W. Calculate the flow rate (drops per minute).

• Answer:

  1.An IV piggyback of 100 mL is to be administered over 40 minutes. The drop factor is 10 gtt/mL. How many drops per minute will be infused? 100ml(10 gtt/ml)=1000 gtt 1000/40=25 drops/min 2. The client is receiving an infusion of 500 mL of D5W at the rate of 25 gtt/min. The drop factor is 12 gtt/mL. How many milliliters per hour is the client receiving? (25gtt/min)(ml/12gtt)=2.0833ml/min 500ml(min/2.0833 ml)=240min 240min(1hr/60min)=3 hrs 500/3=166.667 ml/hr 3. You enter a client s room and note that 600 mL is left in the IV bottle. The client is receiving 25 gtt/min, and the drop factor of your tubing is 15 gtt/mL. How many hours will the IV last? 6 hours 5. The order calls for the infusion of 500 mL of D5W with aminophylline 1 g. The drop factor is 60 gtt/mL. Calculate the flow rate in drops per minute if the client is to receive 0.6 mg/kg/hr by way of continuous infusion. The client weighs 50 kg. 50kg(0.6 mg/kg/hr)=30mg/hr (500ml/1000mg)(30mg/hr)=15ml/hr=15ml/6… (60 gtt/ml)(15ml/60min)=15gtt/min 6. The client is to receive a 1 mg/min infusion of lidocaine hydrochloride. The drop factor is 60 gtt/mL. The order calls for the addition of 750 mg of lidocaine hydrochloride to 500 mL of D5W. Calculate the flow rate (drops per minute). (1 mg/min)(500ml/750 mg)=.666667ml/min (.666667ml/min)(60 gtt/ml)=40 gtt/min
