Final answer:
The correct day supply for the prescription Vigamox 5ml 2Gtts OU BID is 2 days.
Step-by-step explanation:
The prescription Vigamox 5ml 2Gtts OU BID indicates that the patient should take Vigamox, which is an antibiotic eye drop, twice daily in both eyes. The abbreviation 'OU' stands for 'oculus uterque,' which means 'both eyes' in Latin. The abbreviation 'BID' stands for 'bis in die,' which means 'twice a day' in Latin.
To determine the correct day supply for this prescription, we need to know the total volume of the medication and the frequency of use. In this case, the prescription is for a 5ml bottle of Vigamox and the medication is to be taken twice daily. To calculate the day supply, we divide the total volume (5ml) by the amount used per day (4gtts), which gives us a day supply of 1.25 days. However, most pharmacies would round this up to the nearest whole number, so the correct day supply would be 2 days.
