Dosage (Med Admin)

Can someone just check this for accuracy? I may be reading into it too much, but I believe it is accurate.

A patient whose daily fluid intake is restricted to 1,100 ml per day is prescribed six oral meds, two times daily. The nurse restricts the water needed for swallowing the medication so the patient can have fluids with his meals. The patient is allowed 1/2 ounce of water with each pill BID.

How many mL can the patient have with his meals?

14.78675 mL (0.5 oz) per pill x 12 pills per day = 177.44 mL per day with meds. 1100 mL/day – 177.4 ml =922.6/3 = 307.5 mL per meal

Thats what I got. And thank you for working the problemishes, and not just posting the question and waiting for an answer.

Thanks chare! Of course, if I posted expecting an answer, I would not learn anything. Math and Meds, very important. Want to learn. Thanks again for the comment.

My only suggestion would be to use the 1oz = 30cc conversion, and then you can do it in your head on the fly. I&Os are rarely calculated down to the fraction of a cc unless you're working with really small people (who wouldn't be taking pills anyway).

And you get a kudos (yeah, it's a singular noun that ends in s) for presenting your work without being asked or pitching a fit when asked to. Come around any time!

Yes, in practice practice most people do.

Regarding the use of cc, many of us who have been around a while still do this so this is something that you are going to see and heat in the clinical setting.

I agree with AliNajaCat..

12 x.5 = 6oz; 6oz x 30mL/1oz=180mL; 1100mL- 180mL= 920mL/3= 306.7mL per meal

I literally never knew that 1 oz wasn't just plain old 30ml. Mind. Blown.

Even my 3 kg babies don't get their intake measured out to the 5th decimal point. I might chart that their medication was 1.2ml, but by the end of the day I am giving you their total I/Os without fractions.
