We also all know that one of the major challenges in diabetes control actually lies in the lack of patient education. When patients are discharged from the hospital, how to ensure that the results of their own blood glucose monitoring at home are true and accurate? We should perhaps especially instruct the following details: 1. When instructing a newly purchased blood glucose meter, don’t forget to read the manual carefully. Warn the patient to understand the performance requirements, the expiration date of the test strips, and how long it takes to calibrate the blood glucose meter. The test strips opened in the package should be used as soon as possible and single package test strips should be used as much as possible. 2. It is recommended to wash the fingers carefully with warm water and soap before measurement, and then shake them dry. In this way, it is not necessary to wipe with alcohol every time, which is convenient and reduces the pain caused by alcohol inadvertently stimulating the needle hole. 3, it is recommended that the blood be collected on the side of the finger belly, the pain is less, and the blood volume is sufficient. 4. Don’t forget to instruct the patient to go to the hospital or designated place regularly to correct the accuracy of the blood glucose meter.
