National Certified Phlebotomy Technician MCQ Flashcards

Which of the following is not necessary for a properly filled out requisition?

Answer: Patient history

A properly filled out requisition form for blood collection typically requires essential administrative and procedural information. This includes the patient's identification number, the specific tests ordered, and the priority status of the draw. While a patient's medical history is vital for diagnosis and treatment, it is generally not a required component on the blood draw requisition form itself, which focuses on the logistical details of the specimen collection.

Which organization is in charge of overseeing lab workplace safety?

Answer: Occupational Safety and Health Administration (OSHA).

The Occupational Safety and Health Administration (OSHA) is a federal agency responsible for setting and enforcing standards to ensure safe and healthful working conditions for employees. In a laboratory setting, OSHA regulations cover a wide range of safety aspects, including chemical handling, bloodborne pathogens, personal protective equipment (PPE), and emergency procedures, all aimed at protecting lab workers.

What steps should you take to put on PPE properly?

Answer: Gown, Mask, Gloves.

The correct order for donning (putting on) Personal Protective Equipment (PPE) is crucial to prevent self-contamination and ensure maximum protection. The recommended sequence is Gown first, followed by a Mask or respirator, and then Gloves last. This order ensures that the most contaminated items (gloves) are put on last and can be removed first, minimizing the risk of transferring pathogens.

What is the outcome of the 3.2% sodium citrate additive?

Answer: The prevention of clotting by binding calcium.

3.2% sodium citrate is an anticoagulant commonly used in light blue top tubes for coagulation studies. It prevents blood from clotting by binding to calcium ions in the blood. Calcium is an essential cofactor in the coagulation cascade, and by sequestering it, sodium citrate effectively inhibits the clotting process, preserving the sample for accurate testing.

What needs to be done before collecting blood from a sleeping patient?

Answer: Gently wake them up, and when they are ready, request they provide verification of their identity.

Before collecting blood from a sleeping patient, it is imperative to gently wake them up. This ensures they are aware of the procedure, can provide proper identification, and give informed consent. Drawing blood from an unconscious or sleeping patient without their conscious consent and identity verification is a violation of patient rights and safety protocols.

What kind of draw is typically done on young patients?

Answer: Heel stick.

For infants and very young children, a heel stick is the preferred method for capillary blood collection. Their veins are typically too small and fragile for venipuncture, and a heel stick minimizes trauma while providing sufficient blood for common neonatal screenings and tests. This method is safer and less distressing for young patients.

Which of the following would constitute an exception to the finger stick requirement?

Answer: Syringe.

A finger stick is a capillary blood collection method that typically uses a lancet to puncture the skin and collect blood into micro-containers. A syringe, however, is used for venipuncture, which involves drawing blood from a vein. Therefore, a syringe is not a piece of equipment used for a finger stick and would constitute an exception to the supplies required for that procedure.
