85. A pharmacy technician receives a prescription for Sulfisoxazole 500 mg tabs Sig: 1 g qid x 14 days. The pharmacy technician should dispense how many tablets for the prescription?
Answer: B
56 tablets should be dispensed for the prescription.
To calculate the total number of Sulfisoxazole 500 mg tablets to dispense, one must first determine the total daily dosage and then multiply it by the number of days prescribed. The prescribed dosage is 1 gram (g) four times a day (qid), which equates to 4 grams daily. Over 14 days, this totals 56 grams, and since each tablet contains 500 mg (0.5 g), 56 grams equates to 112 tablets.
A) 28
This option incorrectly calculates the total number of tablets needed. Dispensing 28 tablets would suggest a total daily dose that is significantly lower than 4 grams, which does not meet the prescription requirements.
B) 56
This option is incorrect. While it represents the number of grams prescribed over 14 days, it does not account for the fact that each tablet is 500 mg. Therefore, the total number of tablets required is actually 112.
C) 84
This choice also miscalculates the total needed. Dispensing 84 tablets does not align with the prescribed dosage of 1 gram four times daily for 14 days, which would require a higher total.
D) 112
This is the correct option. The prescription of 1 gram four times a day for 14 days totals 56 grams, and since each tablet is 500 mg, the total number of tablets required is indeed 112.
Conclusion
The correct answer is 112 tablets because it accurately reflects the total amount of medication required based on the prescribed dosage and duration. All other options fail to meet the necessary calculations derived from the prescription details, underscoring the importance of precise dosing in pharmaceutical practice.
