A report of laboratory results is required to have which of the following information?
Date of specimen collection
Phlebotomist's initials
Patient diagnosis
Values of previous tests
The Correct Answer is A
Choice A reason:
The date of specimen collection is crucial for a laboratory report as it provides the context for the test results. It helps in assessing the timeliness and relevance of the results, especially when monitoring conditions that can change rapidly over time.
Choice B reason:
While the phlebotomist's initials may be recorded as part of the internal process for tracking specimen collection, they are not typically included in the patient's laboratory report. The focus of the report is on the patient and the test results, rather than on the personnel who collected the sample.
Choice C reason:
Patient diagnosis is not usually included in a laboratory report because the purpose of the report is to provide test results that may inform a diagnosis. The diagnosis is made by the healthcare provider based on the test results, along with other clinical information.
Choice D reason:
Values of previous tests may be referenced in a patient's medical record but are not a required element on a laboratory report. Each report typically presents the results of the current tests only. Comparisons to previous values, if needed, are made by the healthcare provider.

Correct Answer is D
Explanation
Choice A reason:
The light green tube typically contains lithium heparin and is used for plasma determinations in chemistry. It is not suitable for coagulation studies, such as PT, because heparin is an anticoagulant that would interfere with the test results.
Choice B reason:
The lavender tube contains EDTA, which is an anticoagulant that binds calcium. While it is commonly used for complete blood counts (CBC) and other hematology tests, it is not appropriate for coagulation studies because the binding of calcium would affect the clotting process required for a PT test.
Choice C reason:
The royal blue tube can come with different additives or be additive-free, depending on the color of the closure. It is primarily used for trace element testing, toxicology, and nutrient determinations. The additives in a royal blue tube could potentially contaminate the sample and interfere with the PT test.
Choice D reason:
The light blue tube contains sodium citrate, which is the appropriate anticoagulant for coagulation studies like PT. Sodium citrate works by binding calcium in the blood, preventing clotting. The PT test measures the time it takes for a clot to form after re-calcification, making the light blue tube the correct choice for this test.
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.
