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?

50 days
30 days
60 days
25 days

Explanation:

Calculate total insulin units in the vial

Using the Insulin Unit Calculations knowledge point

$$ \text{Total Units} = 10\text{ mL} \times 100\text{ units/mL} = 1000\text{ units} $$

Calculate total daily dose

Using the Insulin Unit Calculations knowledge point

$$ \text{Daily Dose} = 20\text{ units (morning)} + 20\text{ units (evening)} = 40\text{ units/day} $$

Calculate days' supply

Using the Days Supply Calculation knowledge point

$$ \text{Days' Supply} = \frac{1000\text{ units}}{40\text{ units/day}} = 25\text{ days} $$

Answer:

• 50 days
• 30 days
• 60 days
• 25 days (Correct answer)
