405 ml.
For a fluid restriction diet, all substances that are liquid at room temperature are restricted. For the 4 items listed in the meal, that would be the orange juice, milk, and popsicle. So let's calculate that. First, let's do the orange juice and milk:
1/3 * 8 oz = 8/3 oz
1/2 pt * 16 oz/pt = 8 oz
8/3 + 8 = 8/3 + 24/3 = 32/3 = 10.66667 oz
Now let's convert the values into ml.
10.66667 oz * 29.5735 ml/oz = 315.4506667 ml
Now the reason for not adding the popsicle earlier is because 1 popsicle is 90 ml. So add that in.
315.4506667 ml + 90 ml = 405.4506667 ml
Rounding to the nearest ml gives you 405 ml.
