Final answer:
The indicated EHR functionality is lab sample tracking, which allows healthcare providers to track and manage lab specimens from collection to analysis.
Step-by-step explanation:
In this scenario, the EHR functionality indicated would be lab sample tracking.
Lab sample tracking is a feature in electronic health records (EHRs) that allows healthcare providers to track and manage the collection, transportation, and analysis of lab specimens.
In this case, the technician collects a blood sample from the patient for analysis, and the EHR system would track the process from the initial collection to the test results.
In preparation for a scheduled surgery, a patient visits the hospital lab for a blood draw. The technician collects a blood sample and performs a test to determine its type. She places a sample of the patient's blood in two wells. To the first well she adds anti-A antibody. To the second she adds anti-B antibody.
If both samples visibly agglutinate, this indicates that the patient's blood contains both A and B antigens. Therefore, the technician has not made an error; this is a normal response for someone with blood type AB, which is compatible with both anti-A antibodies and anti-B antibodies.
Therefore, the correct answar is a. Lab sample tracking
