Question

4. Order: 1000 mL of 5% D/0.2% NaCl with 10 mEq of KCl for 10 hours. Available: Macrodrip IV set with a drop factor of 20 gtt/mL and microdrip set KCI 20 mEq/20 mL vial. a. How many mililiters (mL) of KCI should be injected into the IV bag? b. How is KCI mixed in the IV solution?wth a l0mL S c. How many drops per minute (gtt/min) should the patient receive with both the macrodrip set and the microdrip set? VALD Micn: 100

Answer 1

1. ANSWER : 5ml

Each ml of Potassium Chloride injection contains 2mEq of potassium and chloride equivalent. So, a vial of potassium chloride contains 10ml which is equal to 20mEq of potassium and chloride. In the question, 10 mEq of injection is needed to add with the 1 litre of solution; that is 5ml (equal to 10mEq)

2. The injection should not be directly pushed into the patient body and should be administered as a dilute solution by using a 10ml syringe.

3. To calculate flow rate of microdrip and macrodrip tubing, convert the rate of administration from ml per hour to ml per minute. 1 HOUR= 60 MINUTES, so take it as 10 x 60 ml per hour.

1000 divided by 10 x 60 = 1.66 ml per minute.

SELECT THE TUBINGS : MACRODRIP TUBING is available as 10gtt/ml or 15gtt/ml and MICRODRIP TUBING is available as 60gtt/ml.

CALCULATE DROPS/MINUTE BASED ON THE TUBINGS:

gtt/minute = (ml/minute) x (gtt/ml)

FOR MACRODRIP : (1.66 ml/minute) x (10gtt/minute) = 17gtt/minute or (1.66ml/minute) x ( 15 gtt/minute) = 30 gtt/minute.

FOR MICRODRIP : (1.66ml/minute) x ( 60gtt/minute) = 100 gtt/minute.
