Which of the following means of receiving an order for specimen collection is considered to be the most accurate method?
Multipart requisition
Manual requisition
Automated requisition
Verbal requisition
The Correct Answer is C
Choice A Reason:
A multipart requisition involves multiple copies of a paper form, which can be prone to errors due to manual entry, misplacement, or illegible handwriting. While it provides physical copies for various departments, it is not the most accurate method compared to digital solutions.
Choice B Reason:
A manual requisition is similar to a multipart requisition but typically consists of a single form. It carries the same risks of human error and does not offer the benefits of automated tracking and data entry that come with electronic systems.
Choice C Reason:
An automated requisition is considered the most accurate method for receiving orders for specimen collection. It reduces the risk of human error associated with manual data entry and allows for better tracking and integration with laboratory information systems. Automated systems can also provide immediate feedback if there is an issue with the order, such as a missing patient identifier or a test code.
Choice D Reason:
A verbal requisition is the least reliable method as it depends on the memory and communication skills of the individuals involved. It lacks the documentation and verification steps present in written or automated methods, making it susceptible to misunderstandings and errors.

Correct Answer is D
Explanation
Choice A reason:
Gastrin is a hormone that stimulates the secretion of gastric acid by the stomach. While it is a critical component in the digestive process, gastrin is not typically sensitive to light, and therefore, does not require protection from light during handling and transportation.
Choice B reason:
Ammonia testing involves measuring the amount of ammonia in the blood, which can indicate liver function and is used in the diagnosis of hepatic encephalopathy. Ammonia levels are not generally affected by light; thus, special precautions to protect from light are not necessary.
Choice C reason:
Pyruvate is a key intermediate in several metabolic pathways throughout the cell. Pyruvate itself is not considered photosensitive, and standard precautions for handling and transportation are sufficient to maintain its integrity.
Choice D reason:
Bilirubin is a breakdown product of red blood cells and is measured to evaluate liver function and to assess jaundice. Bilirubin is known to be photosensitive; exposure to light can cause it to break down, which can affect the accuracy of test results. Therefore, specimens for bilirubin testing must be protected from light during handling and transportation to ensure valid results.
Correct Answer is C
Explanation
Choice A reason:
A specimen bag is typically used for transporting specimens from the collection site to the laboratory. It is not designed for the disposal of contaminated items such as microscope slides. These bags are not puncture-resistant and do not provide the necessary protection against sharps injuries or contamination.
Choice B reason:
A biohazard bag is used for disposing of items that have been contaminated with potentially infectious materials. While it is suitable for materials like gloves, tissues, or any other items that do not have sharp edges, it is not the appropriate choice for glass slides, which can puncture the bag and pose a risk to handlers.
Choice C reason:
A red sharps container is specifically designed for the disposal of sharps waste, which includes any device that can puncture or cut skin, such as needles, syringes, lancets, and contaminated glass such as microscope slides. These containers are rigid, puncture-resistant, leak-proof, and usually marked with a biohazard symbol, making them the correct choice for disposing of contaminated microscope slides.
Choice D reason:
A medical waste container is a broad term that can refer to various types of containers used for medical waste. However, not all medical waste containers are suitable for sharps disposal. Unless the medical waste container is designed like a red sharps container, it may not be safe for disposing of glass slides.
