in killing them.

alert the lab to the possible source of any blood detected in the specimen.

CORRECT. The nurse is likely to give this instruction to the NAP, because the specimen
must be delivered to the lab within 20 minutes of collection. Doing so ensures that the
reliability of the specimen is not compromised.
