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 B
Explanation
Choice A Reason:
Positioning the needle at a 45° angle to the skin is not the recommended approach for venipuncture using a butterfly needle on dorsal hand veins. The correct angle for insertion is usually less than 45°, often around 15-30°, to ensure a shallow entry and reduce the risk of going through the vein.
Choice B Reason:
Holding the needle by the wings of the butterfly is the correct technique. This allows for better control and stability during insertion. The wings are designed to be held between the thumb and forefinger, providing an easy grip for the phlebotomist to maneuver the needle with precision.
Choice C Reason:
Instructing the patient to hold the collection tubes is not standard practice and could lead to pre-analytical errors. The phlebotomist should maintain control of the tubes to ensure proper blood flow and fill volume, as well as to prevent contamination or accidents.
Choice D Reason:
Applying the tourniquet at the antecubital area is not specific to the use of a butterfly needle for venipuncture on dorsal hand veins. While a tourniquet is used to engorge the veins and make them more prominent, its placement may vary depending on the selected puncture site and is not the action in question here.
Correct Answer is C
Explanation
Choice A reason:
Having the bevel down at a 30° angle is not the correct needle position for venipuncture. The bevel of the needle should be facing up to allow for a smoother insertion and to minimize the risk of damaging the vein or causing discomfort to the patient.
Choice B reason:
Positioning the bevel up at a 45° angle is not recommended for venipuncture as this angle is too steep and could lead to the needle penetrating through the vein, potentially causing a hematoma or other complications.
Choice C reason:
The bevel up at a 30° angle is the correct position for venipuncture. This position allows the phlebotomist to insert the needle with the bevel facing upwards, which is the sharpest part of the needle, ensuring a clean entry into the vein. The 30° angle is shallow enough to enter the vein without going through it and causing injury.
Choice D reason:
A bevel down at a 45° angle is incorrect for the same reasons as choice B. Additionally, with the bevel down, the non-beveled side, which is duller, would make the initial contact with the skin, potentially causing more pain and making it more difficult to penetrate the vein.
