Which of the following is caused by excessive shaking of a tube?

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 chain of custody form is crucial in the context of a toxicology drug screen for legal purposes. It is a document that records the sequence of custody, control, transfer, analysis, and disposition of physical and electronic evidence. It is particularly important in legal cases where the results of the toxicology screen can be used as evidence in court. The chain of custody ensures that the sample has been handled properly and that the integrity of the sample has been maintained throughout the testing process.

Choice B Reason:
A requisition form is used to request a specific test or service. While it is an essential document in the process of ordering a toxicology drug screen, it does not serve the same purpose as the chain of custody in terms of legal proceedings. The requisition form typically includes patient information, the tests ordered, and the reason for the test, but it does not track the handling of the sample.

Choice C Reason:
An encounter form, also known as a superbill, is used in medical billing to capture the services provided during a patient's visit. It includes information about the patient's diagnosis, the procedures performed, and the codes for billing purposes. However, it is not specifically related to the legal aspects of a toxicology drug screen.

Choice D Reason:
The CMS 1500 form is the standard claim form used by healthcare providers to bill Medicare and Medicaid services. It is also used by some private insurers and managed care plans. Like the encounter form, it is related to billing and not to the legal chain of custody required for a toxicology drug screen.
