Question

PLEASE READ THE FOLLOWING STEPS BEFORE ANSWERING THE QUESTIONS BELOW

1. • Rules for rounding
   • If you are calculating in tablets, always round to the nearest 1/2 tablet.
   • When you are calculating IV' rates, round to the nearest whole number.
   • Perform rounding only the end of the calculation
2. CONVERSTIONS TO USE
   1 grain =60 mg
   15 grain=1 gram
   1 pint= 2 cups=480mL
   1 quart= 2 pt= 4 cups=960mL
   1 oz= 30 mL
   1 cup = 8 oz = 240 mL
   1 quart = 2 pt = 4cups= 960 mL
   1cc= 1mL
   1tsp= 5mL
   1 Tbs= 15 mL
   1 gallon= 4 qt = 8 pt
3. Note:Some drug conversions will use cc(cubic centimeters) This is the same as a mL. 1cc=1mL
4. Note: (*There are actually 29.57 mL in 1 fl oz, but 30 mL is usually used by nurses in medical facilities. We will stay with this standard for all liquid measurements. 1 oz=30mL, 1 c=240mL, 1 pt=480mL, 1 quart=960mL.)

QUESTIONS:

1. A client receiving a prescription for LR 1,000 mL in 12hr. Using a micro drip system that delivers 60 micro drops/mL, the nurse will regulate the infusion for how many drops per minute.

_____gtts/min. (Round to the nearest whole number-remember no trailing zeros if a whole number)

2. You have an order to administer 1L of 5% Dextrose with 40 meq of potassium over 16 hours. How many mL per hour will you set on the IV pump?___________mL/hr.

(Remember to Round to the nearest whole number)

3. The provider has ordered 1,000 mL of 0.9% sodium chloride (normal saline) to infuse over 8 hr. You have tubing with a drop factor of 15 gtt/mL. You must calculate how many gtt/min to use to set the IV flow rate._______gtts/min (round to the nearest whole number)

4.Critical considerations for prevention of medication errors include all except

a. Follow the 4 rights of safe drug administration

b. None of these are true

c.All of these are correct.

d. Always check drug calculations with a coworker

e. Watch for look alike sound alike

f. Be knowledgeable about the purpose, action side effects, abnormal reactions, delivery methods and follow up

Answer 1

Ans: O volume = 10ooml Time = 12 hrs (1hr = 60 min) Drop actor - 60 12hr = x min. x=60x12= 720 min IV rate = volume x Drop factor Time = 1000 x 60 720 IV rate = 83.33 = 83 ml/min Ans. 15 cans (2) volume - 11 - 1000m Time - 16hr Irrate = ? IV rate = volume in ml Time in hr 1000 16 Rate = 62.5 ² 63 ml/hr.

Iman cans - volume = 1000 ml Time = 8 hr (160= 60 min (ishr=8x60 = 480 min) Drop factor= 15 gtt/min. IV flow rate= volume x Drop factor. Time = 1000 X15 480 Rate = 31.25 gt 1 min ³ 31 gtts /min Ans-4 None of these are true. (b) All the options (a. Ca d , e , f) are correct to prevent medication error.
