A phlebotomist is collecting a urine drug screen from a Department of Transportation employee. The phlebotomist should take the specimen temperature at which of the following times following collection?
Before 4 minutes.
At 5 minutes.
At 15 minutes.
After 30 minutes.
The Correct Answer is A
Choice A Reason:
Taking the specimen temperature before 4 minutes is the correct procedure according to the Department of Transportation (DOT) guidelines. The DOT Rule 49 CFR Part 40 Section 40.65 states that the temperature of the specimen must be checked no later than four minutes after the employee has given the specimen. The acceptable temperature range is 32–38 °C/90–100 °F, which helps to verify the validity of the specimen.
Choice B Reason:
Taking the specimen temperature at 5 minutes is not within the DOT guidelines. The temperature must be taken before 4 minutes have passed to ensure the specimen's integrity and to comply with the regulatory requirements.
Choice C Reason:
At 15 minutes, the temperature check would be too late. The DOT guidelines specify that the temperature should be checked no later than four minutes after collection to ensure the specimen has not been tampered with and is within the acceptable temperature range.
Choice D Reason:
After 30 minutes, the temperature of the urine specimen would not reflect the body temperature at the time of collection, which is necessary for the validity of the test. This delay could allow for the temperature to fall outside of the acceptable range, potentially invalidating the specimen.

Correct Answer is D
Explanation
Choice A reason:
Turning the patient's hand palm down is not typically recommended as it can make the veins less accessible and may cause discomfort to the patient. The veins on the back of the hand are more superficial and can be more easily accessed when the hand is palm up.
Choice B reason:
Placing the patient in a supine position is not necessary for all venipuncture procedures and is usually reserved for patients who have a history of fainting or for those who are already lying down due to their medical condition. It is not a position that specifically increases comfort during the procedure.
Choice C reason:
Bending the patient's arm at the elbow can actually hinder the blood draw process as it may cause the veins to be less prominent and can lead to discomfort or movement during the venipuncture, potentially causing injury or an unsuccessful draw.
Choice D reason:
Positioning the patient's hand at waist level is the correct choice as it allows the arm to be in a natural, relaxed position, which can help the veins to be more prominent and accessible. It also helps in reducing the patient's anxiety as the arm is not in an awkward or strained position.
Correct Answer is C
Explanation
Choice A reason:
A patient's room number is not a unique identifier as it is subject to change. Patients may be moved to different rooms during their hospital stay, and room numbers are not specific to individuals.
Choice B reason:
A patient's bed label is also not a unique identifier. Like room numbers, bed labels can change if patients are moved within the hospital for various reasons, such as changes in their medical condition or room availability.
Choice C reason:
The patient's inpatient chart demographic information is the correct unique identifier to use. This typically includes the patient's name, date of birth, and a unique medical record number assigned by the healthcare facility. These details are specific to the individual and do not change, making them reliable for patient identification.
Choice D reason:
A patient's verbal confirmation alone is not sufficient as a unique identifier. While it is important to engage the patient in the identification process, verbal confirmation must be used in conjunction with other identifiers to ensure accuracy, as patients may be confused or unable to communicate effectively.
