The nurse has an order to administer U-500 Humulin R insulin 10 units. How many units should the nurse draw up when administering this insulin?
50 units of Humulin R insulin in a 100-unit insulin syringe.
10 units of Humulin R insulin in a 500-unit insulin syringe.
10 units of Humulin R insulin in a 30-unit insulin syringe.
50 units of Humulin R insulin in a 50-unit insulin syringe.
The Correct Answer is B
The correct answer is B. 10 units of Humulin R insulin in a 500-unit insulin syringe.
Choice A rationale: This choice is incorrect because a 100-unit syringe would not be able to hold enough U-500 insulin (5 times more concentrated) to deliver the prescribed 10 units. Using a 100-unit syringe could lead to an inaccurate dose.
Choice B rationale: This choice is correct. U-500 Humulin R insulin is a concentrated form containing 5 times more insulin per milliliter compared to U-100 insulin. Therefore, a 500-unit syringe is appropriate to measure the prescribed 10 units accurately.
Choice C rationale: This choice is incorrect. A 30-unit syringe would not have the capacity to hold even the 10 units of U-500 insulin. It would be impossible to draw up the correct dose with this syringe size.
Choice D rationale: This choice is incorrect. Similar to choice A, a 50-unit syringe is not suitable for U-500 insulin due to its limited capacity. It would lead to an inaccurate measurement of the 10-unit dose.
