Final answer:
In mixing insulin, the clear insulin should be drawn first, to avoid contamination and ensure accurate dosing. Insulin injections are used to lower, not increase, blood glucose levels by facilitating glucose uptake into cells.
Step-by-step explanation:
When mixing two types of insulin, such as a short-acting (regular) insulin and an intermediate-acting (NPH) insulin, the clear insulin should be drawn into the syringe first. This is to prevent contamination of the short-acting insulin with the intermediate-acting insulin, which is cloudy. The process is critical for ensuring accurate dosing and the effectiveness of the insulin regimen.
Insulin injections are administered to manage blood glucose levels. Contrary to the provided statement, insulin helps to lower blood glucose levels, not increase them. Insulin enables cells in the body to take in glucose to be used for energy or stored for future use, which is crucial for patients with diabetes who have trouble with natural insulin production or function.
