Which of the following information should a phlebotomist document during a glucose tolerance test?
Flavor of the glucose solution
Time the glucose load was completed
Amount of water ingested during the procedure
Volume of blood obtained during the procedure
The Correct Answer is B
Choice A reason:
The flavor of the glucose solution is not a relevant factor to document during a glucose tolerance test. The flavor does not affect the test outcome and is not a required piece of information for the test's validity or interpretation.
Choice B reason:
Documenting the time the glucose load was completed is crucial. The glucose tolerance test is time-sensitive, and blood samples are taken at specific intervals after the glucose solution is ingested. Accurate timing ensures that the results are valid and that any changes in blood glucose levels are correctly attributed to the patient's metabolic response to the glucose load.
Choice C reason:
While the amount of water ingested during the procedure may be noted for patient comfort, it is not typically a required piece of documentation. The focus of the glucose tolerance test is on the patient's response to the glucose solution, not on the volume of water consumed.
Choice D reason:
The volume of blood obtained during the procedure is generally standardized based on the test requirements and does not need to be documented each time. The phlebotomist must ensure that enough blood is collected for the analysis, but the exact volume is determined by the collection tubes used, which are designed to draw a specific volume.

Correct Answer is B
Explanation
Choice A Reason:
Covering the spill until maintenance arrives is not an appropriate response to a blood spill. This action does not neutralize any potential pathogens present in the blood, which could pose a risk of infection to others. Immediate cleanup is necessary to prevent the spread of infectious diseases, and simply covering the spill does not meet the Occupational Safety and Health Administration (OSHA) guidelines for bloodborne pathogens, which require the spill to be cleaned with an appropriate disinfectant.
Choice B Reason:
Pouring bleach on the spill and allowing it to soak for 60 seconds is the recommended action because bleach is a powerful disinfectant that can kill a wide range of pathogens, including those that might be present in venous blood. The Centers for Disease Control and Prevention (CDC) recommends a 1:10 dilution of household bleach for effectively disinfecting blood spills. After pouring the bleach, it is important to let it soak for an adequate amount of time, usually around 10 minutes, to ensure that all pathogens are killed.
Choice C Reason:
Evacuating the laboratory is not a necessary action for a blood spill unless the spill is extensive and poses additional risks that cannot be mitigated by standard cleanup procedures. In most cases, following the proper spill cleanup protocol, which includes wearing personal protective equipment (PPE) and using an EPA-registered disinfectant, is sufficient to handle the situation without needing to evacuate the area.
Choice D Reason:
Applying a liquid thickening agent on top of the spill is not a standard practice for blood spill cleanup. While a thickening agent might contain the spill, it does not disinfect the area. The priority in such situations is to disinfect and remove any potential infectious agents. Therefore, the use of a thickening agent would not be in compliance with the recommended procedures for blood spill cleanup by OSHA and the CDC.
Correct Answer is C
Explanation
Choice A Reason:
Signing a release for laboratory results is a form of expressed consent, not implied consent. Expressed consent is given explicitly, either orally or in writing, and is clearly and unmistakably communicated.
Choice B Reason:
Similarly, signing a document of agreement for a research study is another example of expressed consent. The patient is actively agreeing to participate in the study, which is a direct and informed action.
Choice C Reason:
Implied consent occurs when a patient's actions suggest consent without verbal or written confirmation. Offering an arm to a phlebotomist is a non-verbal communication that implies the patient is willing to have their blood drawn. This is a common practice in medical settings where the action of presenting an arm indicates readiness for the procedure.
Choice D Reason:
A family member nodding for a phlebotomist to proceed does not constitute the patient's implied consent. Consent must come directly from the patient unless they are unable to provide it, in which case a legal surrogate may give consent on their behalf.
