A nurse is preparing to administer regular insulin to a client. Which of the following actions should the nurse plan to take?

A. Administer the injection IM: Insulin should be administered subcutaneously, not intramuscularly, because IM injections can lead to faster absorption and increase the risk of hypoglycemia. B. Roll the vial to mix the particulate matter within the suspension: Regular insulin is a clear solution and does not contain particulate matter, so rolling the vial is unnecessary. Only cloudy or suspension insulins, like NPH, require gentle mixing. C. Draw up the insulin with a U-500 syringe: U-500 syringes are reserved for clients requiring very high insulin doses. Most standard doses of regular insulin are drawn using U-100 syringes, and using a U-500 syringe unnecessarily increases the risk of dosing errors. D. Verify the dosage with another nurse: Verification by another nurse is a critical safety step, particularly for high-alert medications like insulin. It helps prevent dosing errors and ensures safe administration to the client.
