A phlebotomist is performing a venipuncture on a patient who is allergic to alcohol. Which of the following is an appropriate antiseptic to use in place of alcohol?

Choice A reason:
The light green tube typically contains lithium heparin and is used for plasma determinations in chemistry. It is not suitable for coagulation studies, such as PT, because heparin is an anticoagulant that would interfere with the test results.

Choice B reason:
The lavender tube contains EDTA, which is an anticoagulant that binds calcium. While it is commonly used for complete blood counts (CBC) and other hematology tests, it is not appropriate for coagulation studies because the binding of calcium would affect the clotting process required for a PT test.

Choice C reason:
The royal blue tube can come with different additives or be additive-free, depending on the color of the closure. It is primarily used for trace element testing, toxicology, and nutrient determinations. The additives in a royal blue tube could potentially contaminate the sample and interfere with the PT test.

Choice D reason:
The light blue tube contains sodium citrate, which is the appropriate anticoagulant for coagulation studies like PT. Sodium citrate works by binding calcium in the blood, preventing clotting. The PT test measures the time it takes for a clot to form after re-calcification, making the light blue tube the correct choice for this test.

Choice A Reason:
A quiet and professional tone of voice is essential for a phlebotomy technician when introducing themselves to a patient. This tone conveys respect and maintains a calm environment, which is particularly important in healthcare settings where patients may be anxious or fearful about medical procedures. A professional demeanor helps to establish trust and reassures the patient that they are in capable hands.

Choice B Reason:
A loud and authoritative tone is not appropriate when introducing oneself to a patient. It can be intimidating and may increase the patient's anxiety. The goal is to make the patient feel comfortable and safe, not overpowered or coerced.

Choice C Reason:
Being assertive and humorous can sometimes help to lighten the mood and make the patient feel more at ease. However, humor must be used judiciously as it may not be well-received by all patients, especially in a medical setting where they might be experiencing stress or discomfort.

Choice D Reason:
A commanding and confident tone may convey confidence, but it can also come across as overbearing. While confidence is important, it should not overshadow the need for empathy and understanding of the patient's feelings and comfort.
