Which of the following refers to the process of cleaning up a blood specimen spill on a counter?
Neutralization
Disinfection
Containment
Sterilization
The Correct Answer is B
Choice A Reason:
Neutralization typically involves a chemical reaction to render a substance harmless or inert. In the context of a blood spill, neutralization would not be the primary concern, as the goal is to eliminate any potential infectious agents, not just to neutralize them.
Choice B Reason:
Disinfection is the process of cleaning an area or surface to destroy or prevent the growth of disease-causing microorganisms. When dealing with a blood spill, disinfection is crucial to ensure that any bloodborne pathogens present are effectively killed, reducing the risk of infection transmission.
Choice C Reason:
Containment refers to the measures taken to control or limit something, in this case, a spill. While containment is an important initial step in managing a spill to prevent it from spreading, it is not the process that refers to the actual cleaning and elimination of pathogens.
Choice D Reason:
Sterilization is a process that destroys all forms of microbial life, including spores, usually through the application of heat, chemicals, or irradiation. While sterilization is a more extreme level of decontamination than disinfection, it is not typically used for routine cleaning of blood spills on counters.

Correct Answer is A
Explanation
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 C
Explanation
Choice A Reason:
Hemophilia is a genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding. This condition is not caused by shaking a blood collection tube; it is an inherited disorder typically caused by a mutation in one of the clotting factor genes.
Choice B Reason:
Hemoconcentration refers to an increase in the concentration of cells and solids in the blood, usually resulting from a loss of plasma. While this can occur due to various reasons, such as dehydration, it is not caused by shaking a blood collection tube. Shaking a tube does not change the ratio of cells to plasma in the blood.
Choice C Reason:
Hemolysis is the rupture of red blood cells, which can occur when a blood sample is handled roughly, such as by excessive shaking. This can cause the cells to break open and release their contents into the plasma, which can interfere with laboratory tests and lead to inaccurate results.
Choice D Reason:
Hemostasis is the process by which the body stops bleeding, which involves the clotting of blood. This process is not caused by shaking a blood collection tube. Hemostasis is a complex process that involves blood vessels, platelets, and clotting factors.
