A phlebotomist needs to collect a PT (Prothrombin Time) from a patient with a difficult vein. Which of the following is the best tube for the draw?

Choice A Reason:
Stopping the procedure is the first and most critical action a phlebotomist should take if a patient slumps over during blood collection. The patient's safety is the primary concern, and continuing the procedure could cause further harm. The phlebotomist should immediately remove any needles or equipment from the patient to prevent injury.

Choice B Reason:
Alerting the supervisor is an important step, but it should come after ensuring the patient is safe and the procedure has been stopped. The supervisor will need to be informed of the incident to help manage the situation and provide assistance as needed.

Choice C Reason:
Documenting the incident is a necessary step for legal and medical records. However, it is not the first action to take. The patient's immediate well-being takes precedence over documentation, which can be completed after the situation is under control and the patient is stable.

Choice D Reason:
Sliding the patient to the floor may be necessary if the patient is at risk of falling from the chair. However, this should only be done after the procedure has been stopped, and if it is safe to move the patient. If the patient is unconscious, the phlebotomist may need to initiate CPR, which is best performed on a flat surface.

Choice A Reason:
The timeline of the individual prior to specimen collection is important for context but is not typically part of the chain of custody documentation. The chain of custody focuses on the handling of the specimen rather than the activities of the individual before the collection.

Choice B Reason:
The identity of each person who handles the specimen is a critical element of the chain of custody. This information ensures that the specimen can be tracked at every stage from collection to analysis, and any potential tampering can be identified and addressed.

Choice C Reason:
While the physical and mental status of the individual may be noted in medical records or police reports, it is not a standard part of the chain of custody for a blood alcohol test. The chain of custody's purpose is to track the specimen, not the condition of the individual.

Choice D Reason:
The condition of the specimen every hour is not required in the chain of custody documentation. What is necessary is the documentation of any changes in the condition of the specimen that could affect the integrity of the results, such as temperature excursions or signs of tampering.
