Which of the following pieces of personal protective equipment should a phlebotomist wear to adhere to universal precautions in anticipation of body fluid splashes?
Hair cap
Gown
Shoe covers
Sterile gloves
The Correct Answer is B
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.

Correct Answer is D
Explanation
Choice A reason:
Covering a quarter of the slide is not an acceptable criterion for the quality of a peripheral blood smear. The smear should be spread across the slide in a manner that allows for proper examination under a microscope, and covering only a quarter of the slide would not provide enough area for an adequate assessment.
Choice B reason:
Having a well-defined edge is not specifically indicative of the quality of a peripheral blood smear. While the edges should be clean to allow for clear viewing of the cells at the margins, the quality is more accurately determined by the distribution and integrity of the cells on the slide.
Choice C reason:
Covering the entire slide is also not a criterion for a quality peripheral blood smear. In fact, if the blood covers the entire slide, it may be too thick to allow for proper cell differentiation and examination. A proper smear should have a gradient of cell distribution, ending with a feathered edge.
Choice D reason:
A feathered edge is the correct criterion for a quality peripheral blood smear. The feathered edge is the thinnest part of the smear and is where the cells are ideally distributed in a single layer, which is optimal for microscopic examination. This allows for the best visualization of cell morphology and is essential for accurate diagnosis.
Correct Answer is B
Explanation
Choice A reason:
Collecting the specimen in an SST (serum separator tube) is not suitable for ABG (arterial blood gas) analysis. SST tubes are used for chemistry tests that require serum separation after centrifugation and are not designed for the preservation of blood gases.
Choice B reason:
Placing the specimen in ice is the correct action when transporting a specimen for ABG analysis. Cooling the specimen slows down metabolic processes, which can alter the levels of gases and pH in the blood if not promptly analyzed. This is particularly important if there is a delay expected in the analysis of the ABG specimen.
Choice C reason:
Collecting the specimen in sodium citrate is not appropriate for ABG analysis. Sodium citrate is an anticoagulant used in coagulation studies and would interfere with the measurement of blood gases and pH levels in an ABG analysis.
Choice D reason:
Inserting the specimen in a light-resistant package is not a standard requirement for ABG specimens. While protecting specimens from light is important for certain types of tests, such as those for bilirubin, it is not necessary for ABG analysis.
