A nurse is reinforcing education about administering insulin with a client newly diagnosed with type 1 diabetes mellitus. Which of the following statements by the nurse about injection site selection is accurate?

A. "Injections should be administered into the fatty part under your skin.": Subcutaneous tissue, typically in the abdomen, thigh, or upper arm, allows for slower, more consistent absorption of insulin. Injecting into the fatty layer reduces the risk of rapid absorption or injury to underlying muscle or blood vessels. B. "If you run out of insulin syringes, it is ok to use another type of syringe, as long as you are sure you are administering the correct dose.": Using syringes designed for different insulin concentrations or volumes can lead to dosing errors and hypoglycemia or hyperglycemia. Only the correct syringe type for the insulin concentration should be used. C. "Injections will work most quickly when given deeply into the gluteus muscle.": Intramuscular injection accelerates insulin absorption unpredictably and increases the risk of hypoglycemia. Insulin should not be injected into muscle unless specifically prescribed for rapid absorption in exceptional circumstances. D. "If you are eating there is no need to check glucose before administration.": Blood glucose should be checked before insulin administration to prevent hypoglycemia. Skipping glucose monitoring can be dangerous, especially with rapid-acting insulin.
