Which of the following actions should a phlebotomist take when interacting with a patient who has a "Contact Precautions" sign on their door?
Don a gown prior to entering the patient's room and remove it before leaving the room.
Don a face shield prior to entering the patient's room and remove it after leaving the room.
Don a mask prior to entering the patient's room and remove it before leaving the room.
Don gloves after cleaning and evaluating the patient's venipuncture site.
The Correct Answer is A
Choice A Reason:
When a patient is under "Contact Precautions," it is recommended that healthcare workers don a gown upon entering the patient's room. This is to prevent the spread of infection through contact with the patient or their environment. The gown should be removed before leaving the room to avoid contaminating other areas.
Choice B Reason:
While a face shield may be necessary for certain procedures, it is not specifically required for "Contact Precautions." The primary concern with contact precautions is preventing the transmission of infections through touch, not through droplets, which is what a face shield would protect against.
Choice C Reason:
Donning a mask is not a standard requirement for "Contact Precautions" unless there is a risk of droplet transmission. In this scenario, the precautions are specifically for contact, and therefore, a mask alone would not be sufficient.
Choice D Reason:
Gloves should be donned before any potential contact with the patient or their immediate environment, not just after cleaning and evaluating the venipuncture site. Gloves are a critical component of PPE when dealing with patients under "Contact Precautions."

Correct Answer is A
Explanation
Choice A reason:
Expired tubes may lose their vacuum, which is necessary to draw the correct volume of blood into the tube. The vacuum in blood collection tubes ensures that the correct amount of blood is drawn. If the vacuum is lost, the blood will not be drawn into the tube properly, which can lead to underfilling and affect the test results.
Choice B reason:
Hemoconcentration refers to an increase in the concentration of cells and solids in the blood, usually because of a loss of plasma. While this can occur due to prolonged tourniquet application or dehydration, it is not directly caused by the use of expired tubes.
Choice C reason:
Hemolysis is the destruction of red blood cells, which can release hemoglobin and other intracellular components into the plasma. It can be caused by physical damage, such as from a needle during blood draw, but is not a consequence of using expired tubes. However, if an expired tube causes improper blood draw due to loss of vacuum, it could indirectly lead to hemolysis due to multiple attempts to draw blood.
Choice D reason:
An elevation of the red blood cell count would not be directly caused by using expired tubes. The red blood cell count is determined by the body's production and destruction of red blood cells, not by the collection method or equipment used.
Correct Answer is B
Explanation
Choice A Reason:
Neutralization typically involves a chemical reaction to render a substance harmless or inert. In the context of a blood spill, neutralization would not be the primary concern, as the goal is to eliminate any potential infectious agents, not just to neutralize them.
Choice B Reason:
Disinfection is the process of cleaning an area or surface to destroy or prevent the growth of disease-causing microorganisms. When dealing with a blood spill, disinfection is crucial to ensure that any bloodborne pathogens present are effectively killed, reducing the risk of infection transmission.
Choice C Reason:
Containment refers to the measures taken to control or limit something, in this case, a spill. While containment is an important initial step in managing a spill to prevent it from spreading, it is not the process that refers to the actual cleaning and elimination of pathogens.
Choice D Reason:
Sterilization is a process that destroys all forms of microbial life, including spores, usually through the application of heat, chemicals, or irradiation. While sterilization is a more extreme level of decontamination than disinfection, it is not typically used for routine cleaning of blood spills on counters.
