Question

a pharmacy technician receives a prescription for a 10-ml vial of insulin that contains 100 units/ml. the patient should take 20 units subcutaneously in the morning and 20 units in the evening. which of the following is the days’ supply the patient will receive?

60 days

50 days

25 days

30 days

Explanation:

Step1: Calculate total units in vial

The vial is 10 mL and has 100 units/mL. So total units = volume × units per mL = \(10 \, \text{mL} \times 100 \, \text{units/mL} = 1000 \, \text{units}\).

Step2: Calculate daily units

Patient takes 20 units in morning and 20 units in evening. Daily units = \(20 + 20 = 40 \, \text{units/day}\).

Step3: Calculate days' supply

Days' supply = total units / daily units = \(\frac{1000}{40} = 25\) days.

Answer:

25 days (corresponding to the option "25 days")
