A phlebotomist is collecting a urine drug screen from a Department of Transportation employee. The phlebotomist should take the specimen temperature at which of the following times following collection?
Before 4 minutes.
At 5 minutes.
At 15 minutes.
After 30 minutes.
The Correct Answer is A
Choice A Reason:
Taking the specimen temperature before 4 minutes is the correct procedure according to the Department of Transportation (DOT) guidelines. The DOT Rule 49 CFR Part 40 Section 40.65 states that the temperature of the specimen must be checked no later than four minutes after the employee has given the specimen. The acceptable temperature range is 32–38 °C/90–100 °F, which helps to verify the validity of the specimen.
Choice B Reason:
Taking the specimen temperature at 5 minutes is not within the DOT guidelines. The temperature must be taken before 4 minutes have passed to ensure the specimen's integrity and to comply with the regulatory requirements.
Choice C Reason:
At 15 minutes, the temperature check would be too late. The DOT guidelines specify that the temperature should be checked no later than four minutes after collection to ensure the specimen has not been tampered with and is within the acceptable temperature range.
Choice D Reason:
After 30 minutes, the temperature of the urine specimen would not reflect the body temperature at the time of collection, which is necessary for the validity of the test. This delay could allow for the temperature to fall outside of the acceptable range, potentially invalidating the specimen.

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.
Correct Answer is B
Explanation
Choice A Reason:
While informing the patient of the procedure is important, it is not the immediate next step after greeting. The technician should first ensure the patient's safety and comfort before proceeding with the details of the blood draw.
Choice B Reason:
Asking if the patient has a latex allergy is crucial as it directly pertains to patient safety. Many medical supplies, including gloves and tourniquets used during phlebotomy, may contain latex, which can cause allergic reactions in sensitive individuals. Identifying an allergy before any contact ensures that the technician can take necessary precautions to prevent an allergic reaction.
Choice C Reason:
Stating the technician's name to the patient helps build rapport but is not as critical as ensuring the patient's safety. It is a part of good communication and patient care practices but should follow after confirming any potential allergies or other immediate health concerns.
Choice D Reason:
Asking the patient which arm they prefer for the blood draw is a part of the procedure that involves patient preference and comfort. However, this should come after ensuring there are no allergies that could lead to complications during the draw.
