A phlebotomist is preparing to perform venipuncture for blood collection from a 6-year-old patient. Which of the following needles should the phlebotomist use?
16-gauge
18-gauge
23-gauge
27-gauge
The Correct Answer is C
Choice A reason:
A 16-gauge needle is quite large and is typically used for rapid fluid administration or blood donation in adults. It is not suitable for pediatric patients due to the size of their veins and the potential for causing trauma and discomfort.
Choice B reason:
An 18-gauge needle is also large and commonly used for adult patients in situations where larger volumes of blood are needed quickly. For a 6-year-old patient, this gauge would be too large and could cause significant pain and increase the risk of damaging the vein.
Choice C reason:
A 23-gauge needle is recommended for pediatric patients, including those who are 6 years old. It is small enough to minimize discomfort and the risk of injuring the vein, yet it allows for adequate blood flow for collection³. This size needle is often used with a winged infusion set, which is suitable for the smaller, more fragile veins of pediatric patients.
Choice D reason:
A 27-gauge needle is very small and is typically used for intradermal injections or for very small veins, such as those in neonates. While it would cause minimal discomfort, it may not provide an adequate flow rate for venipuncture in a 6-year-old patient.

Correct Answer is D
Explanation
Choice A Reason:
Disposing of contaminated materials is a part of standard infection control practices. While it is important to dispose of materials that may be contaminated with blood or bodily fluids properly, this action is not specific to the aseptic technique used during venipuncture.
Choice B Reason:
Performing hand hygiene once daily is not sufficient for maintaining aseptic technique. Aseptic technique requires hand hygiene before and after each patient contact, especially before procedures like venipuncture to prevent the transmission of pathogens.
Choice C Reason:
Completing quality control procedures is an essential part of laboratory practice and patient safety but is not directly related to the aseptic technique of venipuncture. Quality control ensures the accuracy and reliability of test results rather than preventing infection.
Choice D Reason:
Cleansing the skin with sodium hypochlorite, or a similar disinfectant, is a critical step in aseptic technique for venipuncture. This action reduces the microbial load on the skin, thereby minimizing the risk of introducing pathogens into the bloodstream during needle insertion.
Correct Answer is A
Explanation
Choice A reason:
Mechanical safety is a critical aspect of laboratory inspections, especially when focusing on equipment maintenance logs. These logs are essential for ensuring that all mechanical equipment is functioning correctly and safely. Regular maintenance and inspection can prevent mechanical failures that could lead to workplace accidents or compromise the integrity of experiments.
Choice B reason:
Chemical safety is undoubtedly important in a laboratory setting; however, it is not the primary focus when the inspection is centered on equipment maintenance logs. Chemical safety would involve the proper storage, handling, and disposal of chemicals, which is a separate concern from the mechanical functioning of equipment.
Choice C reason:
Radiation safety is another vital area in laboratories that work with radioactive materials. However, the maintenance logs for equipment would not typically be the main focus of radiation safety inspections. Instead, radiation safety inspections would concentrate on ensuring proper shielding, monitoring, and training are in place.
Choice D reason:
Electrical safety is also essential, but similar to chemical and radiation safety, it is not the primary focus when inspecting equipment maintenance logs. Electrical safety would involve checking for proper wiring, grounding, and protection against electrical hazards.
