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 D
Explanation
Choice A reason:
The axillary vein is not commonly used for routine venipuncture due to its location in the armpit area, where it is more difficult to access and poses a higher risk of complications.
Choice B reason:
The median cubital vein is often the vein of choice for venipuncture due to its size and accessibility. However, in the case of a patient with bilateral scarring on the forearms, this vein may be compromised, making it a less suitable option.
Choice C reason:
The basilic vein, while also a common site for venipuncture, is located on the inner aspect of the arm and may be affected by the scarring on the patient's forearms. Additionally, it is closer to nerves and arteries, which increases the risk of complications.
Choice D reason:
The dorsal hand veins are a good alternative for venipuncture when the more common sites are not available, such as in the case of a patient with bilateral scarring on the forearms. These veins are usually more superficial and can be accessed with minimal risk of complications.
Correct Answer is C
Explanation
Choice A Reason:
Warfarin does not typically require a fasting state before blood is drawn for testing. The medication's effect on clotting factors is independent of food intake. Therefore, a fasting requirement is not anticipated for patients taking warfarin unless specified for other concurrent tests.
Choice B Reason:
There is no need for an alternate antiseptic due to warfarin use. Standard antiseptic procedures are sufficient when drawing blood from patients on warfarin. The choice of antiseptic would be more influenced by patient allergies or specific institutional protocols.
Choice C Reason:
Patients on warfarin have an increased bleeding time because the medication is an anticoagulant, which means it works to prevent blood clots by thinning the blood. This can lead to prolonged bleeding after a venipuncture, and phlebotomists should be prepared to apply pressure for a longer time to ensure hemostasis.
Choice D Reason:
Placing a specimen on ice is not a standard procedure for blood samples taken for warfarin monitoring, which is typically done through a PT/INR test. This test measures the time it takes for blood to clot and is not affected by temperature in the same way that tests for certain enzymes or gases might be.
