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?

30 days
60 days
50 days
25 days

Explanation:

Calculate the total units of insulin in the vial

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

Calculate the total daily dose required by the patient

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

Calculate the days' supply

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

Answer:

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