Final answer:
After converting the patient's weight to kilograms, we find the patient weighs about 87.54 kg. The total daily dose of ranitidine thus equates to 700.32mg (87.54 kg x 8 mg/kg). Dividing this total daily dose by the number of doses prescribed per day (3), the amount to dispense per dose is roughly 233.44 mg.
Explanation:
To determine the amount of medication per dose, we first convert the patient's weight to kilograms since the medication dosage was prescribed in mg/kg. One pound is approximately 0.453592 kilograms. Therefore, a patient who weighs 193 lb weighs about 87.54 kgs (193 lb x 0.453592 kg/lb). Then, multiplying the patient's weight by the stated dosage (8 mg/kg per day) gives us a total daily dose of 700.32 mg (87.54 kgs x 8 mg/kg).
This total daily dose is then divided by the number of doses per day (every 8 hours implies 3 doses per day) to determine the amount to be dispensed per dose. Hence, the amount of medication the pharmacy technician should dispense each dose is about 233.44 mg/dose (700.32 mg per day / 3 doses per day).
This calculation embodies the careful consideration necessary for drug levels and side effects. Particularly, body mass should be considered when determining dosage, given its noticeable variability among adults.
