What is the first step a nurse should take when preparing to perform a capillary blood glucose test?

When preparing to perform a capillary blood glucose test, the first step is to check the expiration date on the test strips. This step is crucial because expired test strips can lead to inaccurate results, which may significantly affect patient care. Ensuring that the test strips are within their effective date guarantees that the readings obtained will be trustworthy and reliable.

Checking the expiration date also aligns with best practices for maintaining the integrity of medical supplies and safeguarding patient safety. If the test strips are expired, they should not be used, and new ones should be obtained before proceeding with the test. This foundational step is critical in the process of performing any laboratory test, as accurate results are essential for diagnosing and managing the patient's condition effectively.
