When conducting a glucose check, what is the first action to ensure accuracy?

Verifying patient identity is crucial when conducting a glucose check as it ensures that the right individual is receiving care. This step helps prevent errors that could arise from testing the wrong patient's blood, which might lead to misinterpretation of results and inappropriate treatment decisions. Accurate identification is fundamental in clinical practice, as mistakes in administering tests can jeopardize patient safety and treatment efficacy.

Checking the expiration date of the glucometer and the test strips is important, but it comes after confirming whose glucose levels you are measuring. Recording the blood glucose level is part of the process following the actual test and does not relate to ensuring accuracy before performing the test. Lastly, using expired glucometer strips should be avoided entirely, as they can yield inaccurate results and compromise patient safety. Hence, confirming the patient's identity is the most critical first step in this context.
