A phlebotomist finds a patient who is unresponsive and not breathing. In which of the following positions should the phlebotomist place the patient before initiating CPR?
Supine
Semi-Fowler's
Prone
Side-lying
The Correct Answer is A
Choice A Reason:
The supine position, where the patient lies flat on their back with the face upward, is the correct position for initiating CPR. This position allows for proper chest compressions and airway management, which are critical components of CPR.
Choice B Reason:
The Semi-Fowler's position, where the patient is partially sitting up with the head of the bed raised to 30-45 degrees, is not suitable for CPR. This position would make it difficult to perform effective chest compressions.
Choice C Reason:
The prone position, where the patient lies flat on their stomach, is not appropriate for CPR. Chest compressions cannot be effectively delivered in this position, and it would also complicate airway management.
Choice D Reason:
The side-lying position is not appropriate for CPR. While this position can be used for an unconscious patient who is breathing normally to maintain an open airway and prevent aspiration, it is not suitable for CPR, which requires the patient to be on their back.

Correct Answer is B
Explanation
Choice A Reason:
While informing the patient of the procedure is important, it is not the immediate next step after greeting. The technician should first ensure the patient's safety and comfort before proceeding with the details of the blood draw.
Choice B Reason:
Asking if the patient has a latex allergy is crucial as it directly pertains to patient safety. Many medical supplies, including gloves and tourniquets used during phlebotomy, may contain latex, which can cause allergic reactions in sensitive individuals. Identifying an allergy before any contact ensures that the technician can take necessary precautions to prevent an allergic reaction.
Choice C Reason:
Stating the technician's name to the patient helps build rapport but is not as critical as ensuring the patient's safety. It is a part of good communication and patient care practices but should follow after confirming any potential allergies or other immediate health concerns.
Choice D Reason:
Asking the patient which arm they prefer for the blood draw is a part of the procedure that involves patient preference and comfort. However, this should come after ensuring there are no allergies that could lead to complications during the draw.
Correct Answer is D
Explanation
Choice A reason:
Heparin is an anticoagulant, not a clot activator. It works by inhibiting thrombin and preventing the conversion of fibrinogen to fibrin, thus preventing clot formation. It is commonly found in green-top tubes and is suitable for collecting plasma samples for tests like electrolyte levels and coagulation studies.
Choice B reason:
Oxalate is also an anticoagulant that prevents clotting by precipitating calcium. It is not used to promote clot formation but rather to maintain a blood sample in a non-coagulated state for various tests.
Choice C reason:
Citrate functions similarly to heparin and oxalate as an anticoagulant. It chelates calcium ions in the blood, inhibiting the coagulation process. Citrate is often used in blue-top tubes and is ideal for collecting plasma samples for coagulation studies.
Choice D reason:
Silica is a clot activator. It is commonly used in serum separator tubes (SSTs) with a gold or red speckled top. The silica particles provide a surface for the rapid formation of the clot, allowing for the separation of serum from the blood cells. This is essential when serum is needed for testing.
