3) A solution containing 500,000 units of polymyxin B sulfate in 20 mL of sterile water Injection is added to 500 mL of 5% dextrose iniection. The infusion is to be administered over 2.5 hours. If the administration set calibrates 10 drops/mL. At what rate, in drops per minar should the flow be adjusted to administer the infusion over the designated time interval? (Do not ignore volume contribution due to admixture).

Describe how to create the following dilutions using serum and saline as the diluent: 1/20 and 2/10.

Solve the following problems: 1. A medication is infusing at 50 cc/hr. How many cc's will infuse over the entire day? 2. A patient is to receive 1680 ml of a tube feeding formula over the entire day. What should be the infusion rate (in ml per hour) of this formula? 3. A patient is getting an IV fluid infusion. He is to receive a total volume of 1000 cc of this fluid. The infusion rate is 50 cc/hr. How many hours will it take to complete the infusion? 4. A patient is receiving a continuous infusion of a medication. The total amount to be infused is 1440 cc per day. What is the rate of this infusion per minute? 5. A medication is infusing at the rate of 1.2 ml per minute. How much of the medication will be infused after 8 hours? Good luck and have fun!

Margaret, an 80 year old, has come in with dehydration. An IV fluid bolus has been ordered of 500 mL of D5 ½ NS over 4 hours. Using the infusion set label below, calculate the gravity flow rate in drops per minute. 10 gtts/mL CLEARLINK SYSTEM Continu-Flo Solution Set 110' (2.8 m) 3 Luer Lock Adapter

A patient has been prescribed 1L of a saline solution. The rate is set at 150 ml/hr. How long will the infusion take?

If one liter of IV fluid is to infuse between 6:45 a.m. and 3:15 p.m. Calculate the IV drip rate per minute (to the nearest drop) using macro-drip tubing that has a drop factor of 15 drops per milliliter. O 17 gtt/min 29 gtt/min 62 gtt/min 44 gtt/min

A nurse is preparing to administer oxytocin 2 milliunits /min by continously IV infusion to a client. Available is oxytocin 10illiunits/mL. The nurse should set the IV pump to deliver how many mL/hr?

Explain why it is necessary to wash and save erythrocytes in a 290 mUsm /L saline solution rather than in pure water.
