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.

Correct Answer is A
Explanation
Choice A rationale
The patient experiencing anaphylaxis is having difficulty breathing due to bronchoconstriction in response to the allergen. Anaphylaxis is a severe allergic reaction that can cause bronchoconstriction, leading to difficulty in breathing. This is a direct response to the allergen, causing the airways to narrow and making it hard for the patient to breathe.
Choice B rationale
While a rapid fall in blood pressure, also known as hypotension, can occur during anaphylaxis, it does not directly cause difficulty in breathing. Hypotension in anaphylaxis is due to the release of histamines which cause vasodilation and increased capillary permeability, leading to fluid leakage from the capillaries into the tissues, reducing the volume of blood returning to the heart.
Choice C rationale
Reflex tachycardia is a compensatory response by the body to a decrease in blood pressure, not a direct cause of difficulty in breathing. It is the body’s attempt to maintain adequate perfusion by increasing the heart rate.
Choice D rationale
Seizures are not a typical symptom of anaphylaxis. While severe anaphylaxis can lead to a loss of consciousness, it does not cause seizures.
