What is NOT a reason to perform a 2 unit air shot with an insulin pen?

Performing a 2 unit air shot with an insulin pen is typically done for specific purposes related to preparing the device for an accurate injection. Priming the pen is essential to ensure an adequate flow of insulin and to eliminate any air that may lead to inaccurate dosing. The action of releasing a small amount of insulin also ensures that the pen is functioning properly and that the dose set is being delivered as intended.

Regarding the specific purpose outlined in the chosen answer, gauging the depth of the injection is not typically associated with performing a 2 unit air shot. The depth of injection is determined through proper technique and the selection of the appropriate needle length and administration site, rather than through the air shot process. Therefore, this choice highlights a misunderstanding of the purpose of an air shot, which is primarily about preparing the pen and confirming dosing capabilities rather than assessing how deeply the injection will be delivered.
