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 B
Explanation
Choice A Reason:
Wrapping the site with a heel warmer for 30 minutes is a preparatory step before the heel stick procedure. It is used to increase blood flow to the area to make the collection easier. However, it is not the action to take after the blood has been collected. The heel warmer should be removed before performing the heel stick.
Choice B Reason:
Wiping away the first drop of blood is the correct procedure. The initial drop may be contaminated with tissue fluids or alcohol if the site was cleaned prior to the stick, which can affect the accuracy of the test results. Therefore, the first drop should be wiped away, and subsequent blood should be used for the PKU test.
Choice C Reason:
Keeping a pressure dressing on the site for the entire day is not necessary and is not part of the standard heel stick procedure. After the blood is collected, a small bandage is typically applied to stop any bleeding. The site should be monitored for a short time for any signs of continued bleeding or bruising, but a pressure dressing for the day is excessive.
Choice D Reason:
Targeting the central arch area of the foot for the heel stick is incorrect and can be harmful. The recommended area for a heel stick is the lateral portions of the heel to minimize discomfort and avoid injury to the bone or nerves. The central arch area should be avoided to prevent potential harm.
Correct Answer is A
Explanation
Choice A Reason:
The supine position, where the patient lies flat on their back with the face upward, is the correct position for initiating CPR. This position allows for proper chest compressions and airway management, which are critical components of CPR.
Choice B Reason:
The Semi-Fowler's position, where the patient is partially sitting up with the head of the bed raised to 30-45 degrees, is not suitable for CPR. This position would make it difficult to perform effective chest compressions.
Choice C Reason:
The prone position, where the patient lies flat on their stomach, is not appropriate for CPR. Chest compressions cannot be effectively delivered in this position, and it would also complicate airway management.
Choice D Reason:
The side-lying position is not appropriate for CPR. While this position can be used for an unconscious patient who is breathing normally to maintain an open airway and prevent aspiration, it is not suitable for CPR, which requires the patient to be on their back.
