There has been a chemical spill in the laboratory. To which of the following should a phlebotomist refer for directions to clean up the spill?
CLIA
OSHA
SDS
CDC
The Correct Answer is C
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.

Correct Answer is B
Explanation
Choice A Reason:
Wrapping the site with a heel warmer for 30 minutes is a preparatory step before the heel stick procedure. It is used to increase blood flow to the area to make the collection easier. However, it is not the action to take after the blood has been collected. The heel warmer should be removed before performing the heel stick.
Choice B Reason:
Wiping away the first drop of blood is the correct procedure. The initial drop may be contaminated with tissue fluids or alcohol if the site was cleaned prior to the stick, which can affect the accuracy of the test results. Therefore, the first drop should be wiped away, and subsequent blood should be used for the PKU test.
Choice C Reason:
Keeping a pressure dressing on the site for the entire day is not necessary and is not part of the standard heel stick procedure. After the blood is collected, a small bandage is typically applied to stop any bleeding. The site should be monitored for a short time for any signs of continued bleeding or bruising, but a pressure dressing for the day is excessive.
Choice D Reason:
Targeting the central arch area of the foot for the heel stick is incorrect and can be harmful. The recommended area for a heel stick is the lateral portions of the heel to minimize discomfort and avoid injury to the bone or nerves. The central arch area should be avoided to prevent potential harm.
Correct Answer is A
Explanation
Choice A reason:
Inverting the tube 5 to 8 times ensures that the clot activator mixes thoroughly with the blood, promoting proper clotting. Setting the tube aside for 30 minutes allows sufficient time for the blood to clot before centrifugation. This is the recommended procedure to ensure that the serum is properly separated from the clot, resulting in a quality specimen suitable for testing.
Choice B reason:
Inverting the tube only 1 to 3 times may not be enough to mix the clot activator with the blood adequately, which could lead to incomplete clotting and potentially compromised test results. Additionally, setting the tube for 1 hour before centrifugation is longer than necessary and does not offer any advantage over the recommended 30 minutes.
Choice C reason:
Inverting the tube 2 to 4 times might not fully mix the clot activator with the blood, and setting it for only 15 minutes does not provide enough time for proper clot formation. This could result in a suboptimal separation of serum and clot, affecting the integrity of the test results.
Choice D reason:
Inverting the tube 8 to 10 times could potentially cause hemolysis or disruption of the blood cells due to excessive agitation. Setting the tube for 2 hours prior to centrifugation is not recommended as it could lead to serum degradation or other changes that may affect the test results.
