The administration of insulin can vary with respect to the condition of the patient. However, in general, the nurse should administer just a unit of insulin to correct a high blood pressure sugar, so as to drop the blood glucose level by 50 mg/dl.
The drop in blood sugar when insulin is administered this way can be up to 30 to 100 mg/dl or even more, depending on some activities like the sensitivity of an individual to insulin. For some patients, 50 units or less of insulin that is being held in a low dose U-100 syringe is administered to them.
Areas through which you can administer insulin to the patient are the abdomen, thighs, arms, or buttocks. As a matter of fact, insulin is rapidly absorbed when administered through the abdomen, and the absorption can be slow through the buttock. Note that a unit of insulin acting rapidly will dispose of 12 to 15 grams of carbohydrates.
