   • 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
3. 1 grain =60 mg
4. 15 grain=1 gram
5. 1 pint= 2 cups=480mL
6. 1 quart= 2 pt= 4 cups=960mL
7. 1 oz= 30 mL
8. 1 cup = 8 oz = 240 mL
9. 1 quart = 2 pt = 4cups= 960 mL
10. 1cc= 1mL
11. 1tsp= 5mL
12. 1 Tbs= 15 mL
13. 1 gallon= 4 qt = 8 pt
14. Note:Some drug conversions will use cc(cubic centimeters) This is the same as a mL. 1cc=1mL

(*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.)

3. The nurse receives orders to start metronidazole (Flagyl) 50 mg/kg/24 hours divided into three equal doses for a child that weighs 33 lbs. The medication is provided in 250-mg tablets. How many tablets will the nurse provide with each dose?_____tablets

Answer 1

Solution 1: The weight of patient = solb ; 3omg / kg I day Weight of patient in kg = 50.5 = 22.67 kg 22.67 30 = 080-27 70S Solution 2 height of patient = 55lb; 25ml/kg/ho Weight of patient in kg 5 Sos = 24.94 kg 24.94x 25mL = 623.58 ml/hr = 623-6 ml/hr. Solution 3 - liven - Somg/kg Weight ob patien't = 33 lbs, Weight of patient an kg 2205 = 14.96 mg. asong tablets, So, 14.96 will be present in - 14.96 = 0.059 tablet 250 "
