Final answer:
A phlebotomist must confirm that all materials are accounted for and that blood specimens are correctly labeled with the patient's name before leaving the room.
Step-by-step explanation:
Before leaving a patient's room, a phlebotomist must complete several important tasks to ensure both the safety of the patient and the accuracy of the test results. These include confirming that the needle, sponge, and instrument counts are complete, which is essential to make sure no materials have been inadvertently left with the patient. Additionally, the phlebotomist must ensure that any specimens collected, such as blood, are correctly labeled with the patient's name to prevent mix-ups in the lab. Ensuring proper labeling and handling of specimens is critical because it safeguards the integrity of the testing process and ensures that the patient receives the correct diagnosis and treatment based on their specific blood sample.
