11ecbb05_cc7c_1fcf_b433_15b467dcdc74_MD0009_00 An insulin pump is a small, battery-operated device about the size of a pager. The infusion set holds a syringe (reservoir) filled with rapid-acting insulin (175-315 units) and delivers the drug from the pump to the client through a needle or catheter that is usually secured to the abdomen with an adhesive patch. The pump delivers insulin in 2 ways: As a steady, measured, and continuous dose (basal rate) 24 hours a day As an intermittent dose (bolus) administered manually at mealtime to cover carbohydrate intake and as a supplemental dose to correct pre- or postprandial hyperglycemia. CSII therapy delivers the insulin more accurately than injections, so the client experiences fewer swings in blood glucose levels and hypoglycemic episodes, as compared with the administration of insulin using a needle and syringe, or pen. (Option A) Although the pump can calculate and deliver a more precise dose to regulate blood glucose levels more effectively, a bolus dose must be administered manually at mealtime to cover carbohydrate intake. (Option C) Pumps used most commonly (open-loop) cannot respond to changes in the client's glucose levels. The American Diabetes Association recommends that clients using CSII check their blood glucose levels 4-8 times a day: fasting, pre-meal, 2-hours postprandial, bedtime, at 3:00 AM weekly, when experiencing symptoms of hypoglycemia, after treating low blood sugar, and before exercise. Some insulin pumps (closed-loop system) are equipped with continuous blood glucose monitoring (CBGM) systems, which can detect blood glucose levels without a fingerstick. However, CBGM does not completely eliminate the need to test blood sugar because some machines must be calibrated every day to validate accuracy. (Option D) Use of the insulin pump facilitates tighter glucose control, leading to more normal metabolism. However, if the client continues to take in more calories than needed for a given amount of activity or exercise, glucose that is not used by the cells accumulates as fat and results in weight gain. Educational objective: A client prescribed CSII is taught how to self-manage the insulin pump. Key points include the importance of checking blood glucose levels at least 4 times a day, how to administer a bolus dose at mealtime to cover carbohydrate intake, how to administer a supplemental bolus dose to correct pre- and postprandial hyperglycemia, and the importance of balancing diet and exercise to avoid excess weight gain.
