Pharmacy Technician Certification Board Practice Exam Practice Question
A patient presents the following prescription: Humulin 70/30 U-100 Sig: 45 units subcutaneous q.a.m, and 55 units subcutaneous q.p.m. Disp: 30 days supply The number of 10 mL vials to be entered into the patient profile for the quantity ordered is:
Correct Answer: C
Rationale: To determine the number of 10 mL vials needed, first calculate the total daily dosage of Humulin 70/30. The patient requires 45 units in the morning and 55 units in the evening, totaling 100 units daily. Over 30 days, this amounts to 3,000 units (100 units x 30 days).
Each 10 mL vial contains 1,000 units (100 units/mL), so 3,000 units would require 3 vials (3,000 units ÷ 1,000 units per vial).
Option A (1 vial) is insufficient, as it only covers 1,000 units. Option B (2 vials) provides only 2,000 units, still inadequate. Option D (4 vials) exceeds the requirement, providing 4,000 units, which is unnecessary. Thus, 3 vials accurately fulfill the prescription.
