Which of the following actions is appropriate when transporting a specimen for ABG analysis?
Collecting the specimen in an SST
Placing the specimen in ice
Collecting the specimen in sodium citrate
Inserting the specimen in a light-resistant package
The Correct Answer is B
Choice A reason:
Collecting the specimen in an SST (serum separator tube) is not suitable for ABG (arterial blood gas) analysis. SST tubes are used for chemistry tests that require serum separation after centrifugation and are not designed for the preservation of blood gases.
Choice B reason:
Placing the specimen in ice is the correct action when transporting a specimen for ABG analysis. Cooling the specimen slows down metabolic processes, which can alter the levels of gases and pH in the blood if not promptly analyzed. This is particularly important if there is a delay expected in the analysis of the ABG specimen.
Choice C reason:
Collecting the specimen in sodium citrate is not appropriate for ABG analysis. Sodium citrate is an anticoagulant used in coagulation studies and would interfere with the measurement of blood gases and pH levels in an ABG analysis.
Choice D reason:
Inserting the specimen in a light-resistant package is not a standard requirement for ABG specimens. While protecting specimens from light is important for certain types of tests, such as those for bilirubin, it is not necessary for ABG analysis.

Correct Answer is A
Explanation
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 C
Explanation
Choice A reason:
While ensuring that employees receive training regarding workplace hazards is important, it is not the general concept behind standard precautions. Training is a part of the broader safety measures but does not encompass the core idea of standard precautions, which is to prevent infection transmission.
Choice B reason:
Providing information about hazardous chemicals within the environment is related to the Right-to-Know standard, which is part of the Hazard Communication Standard. This is not the main concept of standard precautions, which focus on preventing the spread of infections, particularly in healthcare settings.
Choice C reason:
Assuming that all body fluids are potentially infected with bloodborne pathogens is the essence of standard precautions. This approach dictates that healthcare workers should treat all body fluids as if they are infectious and therefore use appropriate protective measures to prevent exposure and transmission of diseases.
Choice D reason:
Maintaining a workplace free of environmental hazards is a broad occupational safety goal but does not specifically describe the general concept behind standard precautions. Standard precautions are more focused on infection control practices rather than the broader scope of all environmental hazards.
