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 B
Explanation
Choice A Reason:
Wiping the site with clean gauze after applying antiseptic is not recommended. This action can remove the antiseptic before it has had sufficient time to disinfect the area, potentially reintroducing bacteria to the site and increasing the risk of contamination.
Choice B Reason:
Allowing the site to air dry after applying antiseptic is the appropriate technique. This ensures that the antiseptic has enough contact time to effectively reduce microbial flora on the skin. Air drying also prevents any potential irritation that might be caused by wiping or touching the site before the venipuncture.
Choice C Reason:
Blowing on the site to speed up drying is not an appropriate technique. This can introduce bacteria from the breath to the clean site, which could lead to contamination and increase the risk of infection.
Choice D Reason:
Waving hands over the site is not an appropriate technique either. This action could potentially contaminate the site with bacteria or particles from the skin or the environment. It is also less effective in ensuring that the antiseptic has dried completely.
Correct Answer is C
Explanation
Choice A Reason:
CLIA, or the Clinical Laboratory Improvement Amendments, sets standards for all laboratory testing to ensure the accuracy, reliability, and timeliness of patient test results. While CLIA provides a framework for laboratory operation, it does not offer specific guidelines for chemical spill cleanup.
Choice B Reason:
OSHA, or the Occupational Safety and Health Administration, provides regulations to ensure worker safety, including protocols for handling hazardous materials. However, OSHA itself does not provide the specific cleanup procedures; instead, it requires workplaces to follow certain safety practices.
Choice C Reason:
SDS, or Safety Data Sheets, provide detailed information on chemicals, including their properties, health hazards, protective measures, and safety precautions, including spill response and cleanup procedures. In the event of a chemical spill, the SDS contains the most direct instructions for safe and effective cleanup, making it the primary reference for a phlebotomist in this situation.
Choice D Reason:
The CDC, or Centers for Disease Control and Prevention, focuses on public health and disease prevention. While the CDC provides guidelines for infection control and laboratory safety, it is not the primary resource for chemical spill cleanup procedures.
