The infusion pump should be set at what flow rate to administer the fluids in the specified time period? 200 100 500 250 4 Doctor's orders: Infuse a liter of Lactated Ringer's solution over 10 hours. The label on the administration set indicates "microdrip". Calculate the drip rate for this IV infusion. 25 gtt/min 16.67 gtt/min 33.34 gtt/min 100 gtt/min 5 The physician has ordered the TPN to be infused at 112 ml/hr. Using macrodrip tubing on the infusion pump, at what flow rate will the TPN be delivered? 28 cc/hr 37.33 cc/hr 112 cc/hr 166 cc/hr 6 As the nurse makes initial rounds, it is noted that Mr. Harris' IV pump is set on 60 drops per minute. If the drop factor of the soluset for the infusion pump is 15 gtt/cc, how many ml / hr of IV fluids is Mr. Harris receiving? 150 600 15 60 7 Mr. Harris has 2 units of packed RBCs ordered to be given over 4 hours. The label on the blood administration soluset indicates the drop factor of the tubing is 10 gtt/cc. One unit contains 325 ml of blood and the other contains 315 ml.

The doctor's order is for a diuretic challenge of furosemide 80 mg. The nurse places it in 30 ml in the buretrol with a microdrip soluset. Since the drip rate is 60 gtt/min, how long will it take for the medication to infuse? 60 min 30 min 80 min 15 min 9 Mr. Jones has a thrombus and is on a heparin drip.

How many ml per day is this? 1280 1440 960 2340 12 Mr. James is receiving norepinephrine bitartrate (Levophed) via continuous infusion to control his hypotension. If 2 mg of Levophed is mixed in 500 ml of D5NS, what is the flow rate needed to infuse 4 mcg/min? 15 ml/hr. 30 ml/hr 60 ml/hr 75 ml/hr 13 Old doc Jones orders morphine gr 1/4 IM for a client in traction. The nurse has morphine sulfate pre-filled syringes of 15 mg/ml and 50 mg/ml. Which of these represents the correct dose to administer? 0.5 cc using the 15 mg/ml 0.15 cc using the 50 mg/ml 0.6 cc using the 50 mg/ml 1 cc using the 15 mg/ml 14 Old Doc Jones orders 14 minums of a medication. If the medication label indicates 10 mg/ml, how many milligrams of the medication is being ordered? 12 mg 8.75 mg 14 mg 10 mg 15 A client has an order for Vancomycin 150 mg IV q 8 hr. If the pharmacy indicates the medication should be mixed at at concentration of 2 mg / ml, how many ml will the nurse dilute the medication in? 75 ml 150 ml 37.5 ml 18.75 ml 16 A client's IV is infusing at 80 ml/hr. It is currently 12 noon and there is approximately 300 cc of IV fluids remaining. At what time will the nurse need to hang a new bag? 2:50 pm 3:07 pm 5 pm 3:45 pm 17 A client has orders for 40 units of insulin. There are no insulin syringes available. The nurse's only recourse is to use a tuberculin syringe to draw up the insulin. Using a tuberculin syringe, how many cc will the draw up to deliver 40 units of insulin? 0.15 cc 3 cc 0.4 cc 1 cc 18 A client is receiving Lanoxicaps 100 microgams per day. The client's medication box contains Lanoxicaps 0.05 mg. How many capsule(s) should the client be given? 0.5 1 1.5 2 19 The physician writes an order for a client whose weight is 175 pounds.
