Which of the following information should be included with a non-blood specimen that is delivered to the laboratory?
Specimen source
Specimen color
Specimen temperature
Specimen clarity
The Correct Answer is A
Choice A reason:
The specimen source is critical information that must be included with a non-blood specimen delivered to the laboratory. It identifies the origin of the specimen, such as urine, cerebrospinal fluid, or a swab from a specific site. This information is essential for the laboratory to process and analyze the specimen appropriately.
Choice B reason:
While the specimen color may be noted for certain types of specimens, it is not a required piece of information for all non-blood specimens. Color can be an important characteristic for some analyses, but it is not as critical as the specimen source for laboratory processing.
Choice C reason:
Specimen temperature is not typically documented upon delivery to the laboratory unless the specimen requires temperature control during transport, such as certain microbiological cultures. In general, the temperature at the time of collection is not a standard requirement.
Choice D reason:
Specimen clarity might be relevant for specific tests, such as urine analysis, where clarity can indicate the presence of substances like proteins or crystals. However, it is not a universally required piece of information for all non-blood specimens.

Correct Answer is B
Explanation
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:
Anchoring a vein is a technique used to stabilize the vein during venipuncture to prevent it from rolling. The recommended practice is to anchor the vein 1 to 2 inches below the puncture site. This is done by applying gentle traction on the skin downward with the thumb, which helps to stabilize the vein and facilitate the insertion of the needle.
Choice B Reason:
Anchoring 1 to 2 inches above the puncture site is not the standard practice. This position would not provide the necessary tension on the vein to prevent it from rolling and could make the venipuncture more difficult.
Choice C Reason:
Anchoring 2 inches left of the puncture site does not provide the correct angle or tension for stabilizing the vein for a venipuncture and is not a recommended technique.
Choice D Reason:
Anchoring 1 inch right of the puncture site is also not a recommended practice. Similar to anchoring to the left, this does not provide the proper stabilization needed for a successful venipuncture.
