Final answer:

In a standard venipuncture procedure, the blood culture tube is drawn last after other tubes with different additives. Following the correct order is crucial to ensure accurate results and prevent contamination.


Explanation:

The blood culture tube is drawn last in a standard venipuncture procedure. This tube is used to collect blood samples for culturing and identifying possible infections in the blood.

After other tubes with specific additives (such as the lavender tube for EDTA and the light blue tube for coagulation studies) have been collected, the blood culture tube is drawn to prevent contamination.

It is crucial to follow the correct order in venipuncture procedures to ensure accurate test results and prevent cross-contamination.
