Final answer:
To provide a 6-day supply of Sumycin suspension for doses of 250 mg every 6 hours, the pharmacy technician must dispense a total of 240 milliliters of the medication.
Step-by-step explanation:
A pharmacy technician needs to calculate how many milliliters of Sumycin suspension to dispense for a 6-day supply, given a dosage of 250 milligrams (mg) every 6 hours and an available concentration of 125 mg per 5 mL.
Step-by-Step Calculation:
Determine the number of doses in 6 days:
Since the medication is to be taken every 6 hours, there are 4 doses in a 24-hour period. Therefore, for a 6-day supply: 6 days × 4 doses/day = 24 doses.
Calculate the volume of each dose:
The prescription requires 250 mg per dose, and the available Sumycin suspension concentration is 125 mg/5 mL. This means each dose will require: (250 mg) / (125 mg/5 mL) = 10 mL.
Calculate the total volume to dispense:
To find the total volume for a 6-day supply: 24 doses × 10 mL/dose = 240 mL.
The pharmacy technician should dispense 240 milliliters of Sumycin suspension for a 6-day supply.
