Which of the following information should be included in the chain of custody following a blood alcohol testing procedure?
The timeline of the individual prior to specimen collection
The identity of each person who handles the specimen
The physical and mental status of the individual before and after
The condition of the specimen every hour
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice A reason:
Capturing the initial stream of urine, also known as the "first catch," is not recommended for a urine culture. This part of the urine stream can contain contaminants from the urethral opening and is not ideal for culture testing, which requires a clean sample.
Choice B reason:
Cleaning the genital area prior to collection is crucial for obtaining a clean-catch urine specimen. This reduces the risk of contamination from bacteria that are normally present on the skin around the urinary opening. Patients should be instructed to use antiseptic wipes to clean the area before collecting the urine sample.
Choice C reason:
Filling the container to capacity is not necessary and is not a specific instruction for urine culture collection. The focus should be on obtaining a midstream sample after the genital area has been cleaned, which provides a more accurate representation of the urine for culture purposes.
Choice D reason:
Labeling the lid prior to collection is an important step in the process to ensure proper identification of the specimen. However, it is not the primary instruction related to the actual collection of the urine sample. The label should include the patient's name, date, and time of collection and should be done after the sample is collected to avoid confusion or contamination.
Correct Answer is A
Explanation
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.
