NurseDive Free Nursing Practice Question
Which of the following actions is included in aseptic technique when a phlebotomist is performing a venipuncture on a patient?
A. Disposing of contaminated materials
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.
B. Performing hand hygiene once daily
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.
C. Completing quality control procedures
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.
D. Cleansing skin with sodium hypochlorite
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.

Similar Questions
A phlebotomist reports a stat result to a provider by verbal report. What should the phlebotomist include in the follow-up documentation?
A. Patient's insurance information
Patient's insurance information is not typically included in the follow-up documentation of a stat result. Insurance information is relevant for billing purposes and does not pertain to the immediate clinical care or the communication of test results.
B. Room number of the patient
The room number of the patient might be included in the internal documentation for logistical purposes but is not the primary piece of information required following a verbal report of a stat result. The focus should be on the communication details rather than the location.
C. Name of the provider contacted
The name of the provider contacted is essential information in the follow-up documentation after a verbal report. This ensures that there is a record of who received the information, which is crucial for accountability and continuity of care.
D. Provider's phone number
The provider's phone number is not necessary in the follow-up documentation if the name of the provider is already included. The phone number would have been used to make the initial contact, and the key information is the confirmation that the provider was reached and informed of the stat result.

Which of the following information should be included in the chain of custody following a blood alcohol testing procedure?
A. The timeline of the individual prior to specimen collection
The timeline of the individual prior to specimen collection is important for context but is not typically part of the chain of custody documentation. The chain of custody focuses on the handling of the specimen rather than the activities of the individual before the collection.
B. The identity of each person who handles the specimen
The identity of each person who handles the specimen is a critical element of the chain of custody. This information ensures that the specimen can be tracked at every stage from collection to analysis, and any potential tampering can be identified and addressed.
C. The physical and mental status of the individual before and after
While the physical and mental status of the individual may be noted in medical records or police reports, it is not a standard part of the chain of custody for a blood alcohol test. The chain of custody's purpose is to track the specimen, not the condition of the individual.
D. The condition of the specimen every hour
The condition of the specimen every hour is not required in the chain of custody documentation. What is necessary is the documentation of any changes in the condition of the specimen that could affect the integrity of the results, such as temperature excursions or signs of tampering.

A phlebotomist is preparing to draw blood from a patient for therapeutic drug monitoring. Which of the following questions should the phlebotomist ask?
A. "When was your last dose of lithium?"
Asking "When was your last dose of lithium?" is crucial for therapeutic drug monitoring (TDM). TDM is used to tailor dosages and maintain therapeutic levels in a patient’s bloodstream, especially for drugs with narrow therapeutic indices like lithium. The timing of the last dose can significantly affect blood levels, and knowing this information helps in interpreting the results accurately.
B. "For how long have you been fasting?"
While knowing the fasting status of a patient may be relevant for certain tests, it is not typically critical for TDM unless the medication being monitored is affected by food intake. Lithium levels are not significantly influenced by fasting, so this question is less relevant than knowing the timing of the last dose.
C. "When did you have your last alcoholic beverage?"
Inquiring about the last alcoholic beverage is important if alcohol could interfere with the medication's metabolism or the test's accuracy. However, for lithium TDM, alcohol consumption is not as directly relevant as the timing of the last dose. Alcohol does not typically alter lithium levels unless it affects the patient's hydration status.
D. "Have you finished drinking the glucose solution?"
Asking if the patient has finished drinking the glucose solution would be pertinent if conducting a glucose tolerance test. However, this is not relevant for TDM of lithium, as the glucose solution does not interfere with lithium levels or the TDM process. In conclusion, for therapeutic drug monitoring, particularly for lithium, the most critical question is regarding the timing of the last dose. This information is essential to ensure that the blood levels reflect the peak or trough concentration, depending on what is being measured, and to avoid misinterpretation that could lead to inappropriate dosing adjustments.
