Which of the following items should a phlebotomist recognize as part of the aseptic technique protocol?
Standard precautions
Safety devices
Quality control logs
Disaster emergency plan
The Correct Answer is A
Choice A Reason:
Standard precautions are a set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin (including rashes), and mucous membranes. These measures are to be applied to all patients, regardless of their diagnosis or presumed infection status. Standard precautions include hand hygiene, use of personal protective equipment (PPE), respiratory hygiene/cough etiquette, safe injection practices, safe handling of potentially contaminated equipment or surfaces in the patient environment, and aseptic technique.
Choice B Reason:
Safety devices, such as needles with engineered sharps injury protections, are designed to prevent needlestick injuries and the transmission of bloodborne pathogens. While they are an important aspect of a phlebotomist's work, they are not specifically part of the aseptic technique protocol. Aseptic technique focuses on preventing contamination of sterile surfaces and materials to prevent infection.
Choice C Reason:
Quality control logs are records that document the performance of equipment and procedures to ensure they meet the required standards. They are essential for maintaining the integrity of laboratory results and ensuring patient safety. However, quality control logs themselves are not a component of the aseptic technique protocol, which is more concerned with the immediate prevention of infection during clinical procedures.
Choice D Reason:
A disaster emergency plan is a comprehensive document outlining the actions to be taken in case of an emergency. This plan is crucial for ensuring safety and continuity of care during unexpected events but is not related to the aseptic technique protocol. Aseptic technique is a method used to prevent infection during medical procedures by maintaining a sterile environment.

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 C
Explanation
Choice A Reason:
Shaking the tubes vigorously can cause hemolysis, which is the rupture of red blood cells, leading to inaccurate test results. It is not recommended as it does not provide gentle mixing and can damage the blood cells.
Choice B Reason:
Moving the tubes in a figure-eight motion is not a standard practice for mixing blood samples. This method may not provide the consistent and gentle inversion needed to mix the anticoagulant with the blood effectively.
Choice C Reason:
Rolling the tubes between the palms of the hands 4 to 8 times after collection is the recommended method. This technique allows for gentle and thorough mixing of the blood with the anticoagulant, preventing clotting without causing hemolysis. The number of inversions ensures that the anticoagulant coats the inner surface of the tube and mixes with the blood, which is essential for accurate laboratory results.
Choice D Reason:
Passing the tubes from hand to hand is not an effective method for mixing blood samples. This action may not provide the necessary inversion and can lead to inadequate mixing, resulting in clotted specimens.
