0.5g means 500mg.

So two tablets must be administered.

10. Mr. J is admitted for dehydration and has 0.75 L of Lactated Ringers still to infuse prior to his discharge home. How many mL are there in 0.75L?

one litre = 1000 ml

0.75 L = ?

= 0.75*1000 = 750 ML

11. Calculate Mr. L’s fluid intake in mL for the past 24 hours. Breakfast: 8 fluid ounces of milk, 6 fluid ounces of orange juice, and 4 fluid ounces of water with his medication. Lunch: 8 fluid ounces of iced tea. Dinner: 8 fluid ounces of water, 6 fluid ounces of beef broth, and 6 fluid ounces of tomato juice.

Lunch:

8 fluid ounces of iced tea.

Total = 8 = 8 fluid ounces

Dinner:

8 fluid ounces of water,

6 fluid ounces of beef broth,

6 fluid ounces of tomato juice.

Total = 8+6+6 = 20 fluid ounces

Snack:

5 fluid ounces of pudding,

12 fluid ounces of diet soda,

4 fluid ounces of water with his medication.

Total = 5+12+4 = 21 fluid ounces

Overall = 18+8+20+21 = 67 fluid ounces

1 us fl oz = 29.57ml

67 floz = 1981.43 ml
