What action should be taken after collecting a urine specimen?

The most appropriate action after collecting a urine specimen is to inject it into a sterile specimen container. This step is crucial for ensuring that the sample remains uncontaminated and suitable for accurate testing. Using a sterile container helps preserve the integrity of the sample, preventing microbial contamination and allowing for reliable laboratory analysis.

This procedure typically involves transferring the urine from the collection device into a designated container that is sterile, ensuring that the results of any tests conducted on the sample are valid. Proper handling and storage of the urine specimen are essential to maintain its viability for diagnostic purposes.

Other options involve actions that either compromise the sample's integrity or are not standard procedures in specimen collection and handling. For instance, reinserting the needle into the injection port is not relevant after urine collection as it's not part of the urine sampling process. Disposing of the sample immediately contradicts the need for analysis, and letting the urine sit without any further action would not be appropriate, as urine specimens often should be processed promptly to avoid changes in composition.
