Which action should the nurse avoid prior to administering a subcutaneous insulin dose?

Administering insulin too far in advance of a meal can lead to hypoglycemia, especially if the patient does not consume food after receiving the insulin. The timing of insulin administration is crucial for maintaining blood glucose levels within a target range. Typically, rapid-acting insulin should be given right before a meal or immediately after starting a meal to match the rise in blood glucose levels that occurs after eating.

By administering the insulin one hour prior to a meal, there's a risk that the insulin will lower the blood glucose level before the carbohydrates from the meal are available to counteract that effect. This can lead the patient to experience symptoms of low blood sugar, such as dizziness, shakiness, or even more severe reactions, depending on the individual’s response.

In contrast, confirming the insulin type, checking blood glucose levels, and educating patients on injection techniques are all essential and appropriate steps in the process of safely administering subcutaneous insulin. These actions enhance the safety and effectiveness of insulin therapy.
