The client has an order for 30 units of U-500 insulin. The nurse is using a U-100 syringe and will draw up and administer:

1. 5 units
2. 6 units
3. 10 units
4. 30 units

ANSWER

ANS: 2
U-500 insulin is 5 times as strong as U-100 insulin. Therefore the amount of U-500 insulin should be divided by 5. 30 units of U-500 insulin ÷ 5 = 6 units of insulin to draw into a U-100 syringe. Options 1, 3, and 4 are incorrect dosages.
