Final answer:
To calculate the amount of grams a patient would receive for a 10-day therapy of cephalexin 250mg/5mL PO TID, convert the dose from milligrams (mg) to grams (g). Calculate the total amount of cephalexin consumed per day, then multiply by 10 days.
Step-by-step explanation:
In order to determine how many grams a patient would receive for a 10-day therapy of cephalexin 250mg/5mL PO TID, we need to calculate the total amount of cephalexin consumed per day and then multiply it by 10 days.
First, we need to convert the dose from milligrams (mg) to grams (g). We can do this by dividing the dose by 1000:
Cephalexin dose per 5mL = 250mg/5mL = 50mg/mL = 0.05g/mL
Next, we need to calculate the total amount of cephalexin consumed in a day:
Cephalexin dose per day = 0.05g/mL x 3 times a day = 0.15g/day
Finally, we multiply the cephalexin dose per day by the number of days in the therapy:
Total amount of cephalexin received in a 10-day therapy = 0.15g/day x 10 days = 1.5g
Therefore, a patient would receive 1.5 grams of cephalexin for a 10-day therapy.
