10 points. math problem. this will be a challenge. im smart and i cant figure this out all. help?? (description)?

a doctor ordered 1000 cc D5W and let it out at a rate of 600 cc every 8 hours, to maintain hydration levels. He checked his calculations twice and listed it on the infusion chart at 200 mL/hr. the NURSE started the infusion with a 1000 cc D5W bag and administered it to the patient. once that bag was done she hung another for infusion. the patient started to show some unusual symptoms during the time the 3rd 1000 cc D5W bag was being dispensed. they noticed the patient was experiencing water intoxication bc of the high infusions. his sodium level was 107 mEq/L whereas the normal level is 136-145 mEq/L. the patient died.

Assuming all 3 bags were completely administered, how much D5W did the patient actually get compared to the amount orderd?

Assuming the doctors orders were correct, what should the rate have beenin cc per hour?

How long should the IV should have administered the the 1000 cc ordered by the doctor?

By what percent was the patient's sodium level beneath normal range?

Where did the patients treatment go wrong?

What can the hospital do to keep from these events reoccurring?
