Insulin self-administration teaching

In this pharmacology question, we need to identify the correct instruction for a client newly diagnosed with Type 1 diabetes regarding the self-administration of insulin.

Let's evaluate each option to see which aligns with standard medical practice.

The first option suggests pulling back on the plunger, also known as aspiration, after injecting. This is incorrect. Aspiration is not recommended for subcutaneous insulin injections as it can cause tissue trauma.

The second option suggests massaging the injection site. This is also incorrect because massaging the area after administration can alter the absorption rate of the insulin and potentially lead to hypoglycemia.

The third option recommends storing the current bottle of insulin at room temperature. This is actually a correct piece of advice. While unopened insulin should be refrigerated, the vial currently in use can stay at room temperature for up to twenty-eight to thirty days to minimize local irritation at the injection site.
