There was a math question on the final exam last semester. I got the wrong answer and none of the teachers were willing to give me the correct answer, or explain to me what I did wrong.
Each semester there is a question like this on the final and I always seem to get stuck on it. It is regarding input and output.
Question : A patient who has a catheter took in 6 oz of Orange Juice and 4 oz of Apple Juice. Irrigation was 2000 ml . At the of the catheter bag reads 2270 ml. What would you record as the patient's input and output?
My answer was 30 input and 270 output. Because 2000 was just irrigation fluid, I subtracted 2270 ml - 2000 ml. Then I subtracted 300 ml from 270 to get input. I don't understand what I did wrong.
Thank you so much!
If there is 30ml/1oz and the patient had 6oz/180cc of orange juice and 4oz/120ml of apple juice they had a total of 300mls PO intake
If you have a foley irrigation that has infused 2,000mls and you measure 2270mls out of the foley bag...2270mls irrigation/urine - 2000mls/irrigation...you have had 270mls urine output
Why would you do anything else with you PO intake and output other than to know whether your patient is running positive or negative.
More in than out you are running a positive fluid balance
More out then in you are running a negative fluid balance
You patient for this shift has had a positive fluid balance of 30mls (more in than out) but the total intake and output for this shift is...... a total of 300mls in and 270mls total out
...which is your I/O for that shift
