When an HbA1c test is ordered, the primary action required is to obtain a blood sample from the patient. The HbA1c test measures the average blood glucose levels over the past two to three months, which is crucial for monitoring diabetes management and determining how well the patient's blood sugar is controlled over time. This blood sample will then be analyzed in a laboratory to provide the necessary data for making informed decisions about treatment and care.

The other options, while relevant in the broader context of diabetes management, do not directly pertain to the immediate action following the order for an HbA1c test. Scheduling a follow-up appointment, administering a urine test, or providing dietary advice may be part of a comprehensive management plan, but they are not the correct immediate step following the order of the HbA1c test itself. In this case, prioritizing the collection of the blood sample is essential for obtaining the required diagnostic information.
