Since this patient can ambulate using a walker, she should be encourage to urinate in the toilet. If the patient is having pain upon walking and doesn't think they can get to the bathroom safely even with the nurses help. The patient can have a bedpan placed underneath them to urinate in.

The "eight glasses a day" rule presumes 8-oz glasses:
8 x 8 = 64 oz = 2 quarts
1 quart = 946 ml x 2 = 1892 ml
So you should drink 3.784 of those 500ml bottles of water.
Looked at another way, each of those 8oz glasses of water holds 236.5 ml, so if you drink all four 500ml bottles of water, you're drinking a little more than 8 1/2 glasses of water.
Looked at a third way, if you measure an extra half-ounce of water into each of your eight glasses, you're up to four 500ml bottles.
