The physician writes an order for 0.1 g of a drug per dose. You have available 100 mg tablets. How many tablets should be given to your patient? 17. Your patient needs 400 mg of an drug oral suspension. The label tells you that the drug is available as 200 mg/5 ml. How many milliliters should you give?

Answer 1

1. 88 millimeter = 8.8  centimeters (1cm = 10mm)

2. 9876 milliliters = 9.876 liters ( 1L = 1000mL)

3. 3.5 liters = 3500 milliliters

4. 2200 milligrams = 2.2  grams (1g = 1000mg)

5. 650 grams = 0.65 kilograms (1 kg = 1000g)

6. 7.6 kilogram = 7600 grams

7. 0.125 grams = 125 milligrams

8. 365 meters = 0.365 kilometers (1km = 1000m)

9. 2500 micrograms = 2.5 milligram (1mg = 1000 microgram)

10. 89700 milliliters = 89.7 liters

11. 94.3 kg = 94300000 mg (1kg = 1000g= 1000000mg)

12. 98g = 0.098  kg

13. 9m = 9000 mm

14. 7656ml = 7.656 L

15. 6600 mm = 6.6 m

16. 0.1 g = 100mg, hence 1 Tablet of 100mg per dose given

17. Volume (mL) = dose (mg) / concentration (mg/mL) = 400 / (200/5) = 10 mL

Hence 10mL corresponds to 400 mg and 10 milliliters is to be given
