Which of the following should a phlebotomist anticipate for a patient who has been taking warfarin?

Choice A reason:
The BUN test measures the amount of urea nitrogen in the blood, which can indicate kidney function. Fasting is not typically required for a BUN test unless it is being conducted alongside other tests that may require fasting.

Choice B reason:
An HDL test is part of a lipid profile that measures the levels of good cholesterol in the blood. Fasting before a cholesterol test, including HDL, is often recommended to ensure accuracy, although recent guidelines have changed, allowing for nonfasting cholesterol testing in certain individuals.

Choice C reason:
An ABG test measures oxygen and carbon dioxide levels in the blood and assesses the body's acid-base balance. Preparation for an ABG test does not typically require fasting, but patients may need to stop supplemental oxygen before the test to get accurate measurements.

Choice D reason:
A CBC test, or complete blood count, does not require fasting. It measures various factors of the blood, including red and white blood cells and platelets. Fasting is not necessary unless the CBC is part of a panel of tests that includes tests requiring fasting.

Choice A reason:
A hair cap is used to prevent contamination from the hair, but it is not specifically designed to protect against body fluid splashes. While it is a part of personal protective equipment (PPE), it does not provide coverage for the areas most likely to be exposed to splashes during phlebotomy procedures.

Choice B reason:
A gown is the appropriate choice for protection against body fluid splashes. It covers a significant portion of the body and is designed to prevent fluids from reaching the phlebotomist's skin or undergarments, which is essential when there is a risk of splashes during procedures like venipuncture.

Choice C reason:
Shoe covers protect the feet from contamination, but they are not typically necessary for phlebotomy unless there is a significant risk of large fluid spills on the floor. They are more commonly used in operating rooms or during the cleaning of large spills.

Choice D reason:
Sterile gloves are a standard requirement for phlebotomy to maintain aseptic technique and prevent contamination. However, gloves alone do not provide sufficient protection against body fluid splashes that may reach other parts of the body.
