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 B
Explanation
Choice A Reason:
Shoe covers are used to protect the shoes and prevent the spread of contaminants from one area to another. They are not specifically required for droplet precautions during blood glucose monitoring. Droplet precautions typically focus on protecting mucous membranes of the eyes, nose, and mouth from droplet spatter.
Choice B Reason:
Masks are essential when dealing with patients under droplet precautions. Droplets can transmit infections when a person coughs, sneezes, or talks, and a mask provides a barrier that prevents the inhalation of these potentially infectious droplets. For procedures like blood glucose monitoring, where close contact with the patient is necessary, wearing a mask is crucial to protect both the healthcare worker and the patient.
Choice C Reason:
A gown is used to protect the healthcare worker's skin and clothing from contamination with potentially infectious material. While it is an important piece of personal protective equipment, it is not the primary requirement for droplet precautions in the context of blood glucose monitoring, unless there is a risk of substantial splashing or spraying of bodily fluids.
Choice D Reason:
Goggles are used to protect the eyes from splashes of blood or other body fluids. They are important in procedures where there is a risk of splashing, but for blood glucose monitoring, the risk is minimal. Therefore, goggles are not the primary piece of equipment required for droplet precautions in this scenario.
Correct Answer is D
Explanation
Choice A Reason:
A red-top tube is used for serum determinations in chemistry and should be allowed to clot completely, typically for 30 minutes, before centrifugation. Shipping after only 15 minutes may result in incomplete clotting and potentially inaccurate test results.
Choice B Reason:
Serum should not be separated from a lavender-top tube, as this type of tube contains EDTA and is used for whole blood tests, not serum. This indicates a misunderstanding of the tube's purpose and could lead to compromised test results.
Choice C Reason:
A tiger-top tube, also known as a serum separator tube, is used for various chemistry tests. However, bilirubin is light-sensitive, and specimens for bilirubin testing should be protected from light, not shipped in a clear bag. This could lead to degradation of the bilirubin and inaccurate results.
Choice D Reason:
A green-top tube contains heparin and is used for plasma determinations. Ammonia testing requires the plasma to be placed on ice immediately after collection to inhibit the continued production of ammonia from red blood cells. Therefore, shipping in an icy water mixture is the correct procedure to ensure accurate ammonia levels.
In conclusion, the proper preparation and transport of blood specimens are crucial for the accuracy of laboratory tests. The green-top tube for ammonia testing, shipped in an icy water mixture, is the only option that follows the correct protocol for specimen handling and transport.
