Which of the following forms commonly accompanies a toxicology drug screen for legal purposes?
Chain of custody
Requisition
Encounter
CMS 1500
The Correct Answer is A
Choice A Reason:
The chain of custody form is crucial in the context of a toxicology drug screen for legal purposes. It is a document that records the sequence of custody, control, transfer, analysis, and disposition of physical and electronic evidence. It is particularly important in legal cases where the results of the toxicology screen can be used as evidence in court. The chain of custody ensures that the sample has been handled properly and that the integrity of the sample has been maintained throughout the testing process.
Choice B Reason:
A requisition form is used to request a specific test or service. While it is an essential document in the process of ordering a toxicology drug screen, it does not serve the same purpose as the chain of custody in terms of legal proceedings. The requisition form typically includes patient information, the tests ordered, and the reason for the test, but it does not track the handling of the sample.
Choice C Reason:
An encounter form, also known as a superbill, is used in medical billing to capture the services provided during a patient's visit. It includes information about the patient's diagnosis, the procedures performed, and the codes for billing purposes. However, it is not specifically related to the legal aspects of a toxicology drug screen.
Choice D Reason:
The CMS 1500 form is the standard claim form used by healthcare providers to bill Medicare and Medicaid services. It is also used by some private insurers and managed care plans. Like the encounter form, it is related to billing and not to the legal chain of custody required for a toxicology drug screen.

Correct Answer is A
Explanation
Choice A Reason:
Explaining the procedure to both the parent and the child is crucial. It helps in preparing the child psychologically and ensures that the parent is informed and can provide support during the process. Clear communication can reduce anxiety and make the child more cooperative. It is also a part of informed consent, where the parent understands what the procedure entails and why it is necessary¹².
Choice B Reason:
Choosing not to tell the child when the needle insertion is coming might seem like a way to avoid causing them anticipatory anxiety. However, this approach can lead to mistrust. Children need to be prepared for what to expect, and surprising them can be more traumatic in the long run. It is better to be honest and use age-appropriate language to describe the sensation as a 'quick pinch' or 'poke'¹².
Choice C Reason:
Obtaining a heel stick is a common method for blood collection in infants, particularly newborns, as their veins are not as developed. However, for preschoolers, venipuncture is usually the preferred method because they have more developed veins, and it allows for a larger volume of blood to be collected if needed³.
Choice D Reason:
Obtaining a thumb stick is not a standard practice for blood collection in preschoolers. The thumb has bones and tendons close to the surface, which can increase the risk of injury. The preferred sites are the antecubital fossa of the arm or the back of the hand where the veins are more accessible and there is less risk of hitting bone³.
Correct Answer is C
Explanation
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.
