A diabetic patient is prescribed 6 units of insulin subcutaneously. The insulin vial reads U-100 (100 units/mL). How many mL should the nurse administer?

Calculation: U-100 insulin means 100 units per 1 mL. Ordered dose: 6 units mL to administer = Ordered dose ÷ Concentration mL = 6 units ÷ 100 units/mL = 0.06 mL
