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:
Disposing of contaminated materials is a part of standard infection control practices. While it is important to dispose of materials that may be contaminated with blood or bodily fluids properly, this action is not specific to the aseptic technique used during venipuncture.
Choice B Reason:
Performing hand hygiene once daily is not sufficient for maintaining aseptic technique. Aseptic technique requires hand hygiene before and after each patient contact, especially before procedures like venipuncture to prevent the transmission of pathogens.
Choice C Reason:
Completing quality control procedures is an essential part of laboratory practice and patient safety but is not directly related to the aseptic technique of venipuncture. Quality control ensures the accuracy and reliability of test results rather than preventing infection.
Choice D Reason:
Cleansing the skin with sodium hypochlorite, or a similar disinfectant, is a critical step in aseptic technique for venipuncture. This action reduces the microbial load on the skin, thereby minimizing the risk of introducing pathogens into the bloodstream during needle insertion.
Correct Answer is D
Explanation
Choice A Reason:
Keeping the patient as upright as possible is not recommended in cases of shock. When a patient is in shock, it is important to lay them down and elevate their legs slightly, unless this position causes pain or further injury. This position helps improve blood flow to the brain.
Choice B Reason:
Providing a cooling blanket is not a standard first aid measure for shock due to a medication reaction. A cooling blanket may be used in cases of hyperthermia or heatstroke to reduce body temperature, but not typically for shock, which requires maintaining normal body temperature and preventing chilling.
Choice C Reason:
Administering oral fluids to a patient in shock is not advisable. During shock, a patient may have an impaired swallowing reflex or be unconscious, increasing the risk of aspiration. It is best to avoid giving anything by mouth until medical personnel arrive.
Choice D Reason:
Maintaining an open airway is crucial for a patient in shock. Ensuring that the airway is clear allows the patient to breathe effectively, which is essential for delivering oxygen to the tissues and organs. If the patient is unconscious or has an altered level of consciousness, the phlebotomist should check for breathing and begin CPR if necessary.
