PCT Phlebotomy – Duties and Responsibilities — Questions and Answers
Question 1: What is the primary responsibility of a phlebotomist?
- Administering medications.
- Performing diagnostic imaging.
- Collecting blood specimens accurately (Correct answer)
- Prescribing treatments.
Correct answer: Collecting blood specimens accurately
A phlebotomist's primary responsibility is to collect blood specimens from patients accurately and safely. This involves proper patient identification, selecting the correct venipuncture site, using appropriate equipment, and ensuring the integrity of the collected sample for diagnostic testing. Their role is vital for accurate laboratory results.
Question 2: Why is patient identification crucial before phlebotomy?
- To speed up the procedure.
- To avoid using too many supplies.
- To prevent sample contamination.
- To ensure the right patient receives the right test (Correct answer)
Correct answer: To ensure the right patient receives the right test
Patient identification is paramount in phlebotomy to prevent medical errors and ensure patient safety. Verifying the patient's identity against the test requisition ensures that the correct blood samples are collected from the intended individual for the specific tests ordered. Misidentification can lead to incorrect diagnoses and treatments.
Question 3: What is the best way to avoid infection during blood collection?
- Using the same needle for all patients.
- Avoiding hand hygiene.
- Wearing gloves and using aseptic technique (Correct answer)
- Touching the puncture site directly.
Correct answer: Wearing gloves and using aseptic technique
Wearing gloves and consistently using aseptic technique are the most effective ways to prevent infection during blood collection. Gloves protect both the patient and the phlebotomist from bloodborne pathogens, while aseptic technique minimizes the introduction of microorganisms into the puncture site or the blood sample. This prevents healthcare-associated infections.
Question 4: How should a phlebotomist respond if a patient feels faint?
- Ignore the symptoms and continue.
- Continue quickly to finish the draw.
- Stop the procedure and provide care (Correct answer)
- Call another patient instead.
Correct answer: Stop the procedure and provide care
If a patient feels faint or shows signs of syncope during a blood draw, the phlebotomist must immediately stop the procedure and prioritize the patient's safety. This involves removing the needle, applying pressure to the site, and assisting the patient to a safe position (e.g., lying down) to prevent injury from falling. Providing care and monitoring their condition is essential.
Question 5: Which vein is commonly used for venipuncture?
- Femoral vein.
- Jugular vein.
- Median cubital vein (Correct answer)
- Radial artery.
Correct answer: Median cubital vein
The median cubital vein, located in the antecubital fossa (inner elbow area), is the most commonly used and preferred site for venipuncture. It is typically large, well-anchored, and easily accessible, making it ideal for drawing blood with minimal discomfort and risk of complications.
Question 6: Why is it important to label blood specimens immediately?
- To use up all labels.
- To impress the supervisor.
- To prevent specimen identification errors (Correct answer)
- To skip documentation.
Correct answer: To prevent specimen identification errors
Labeling blood specimens immediately after collection, at the patient's bedside, is critical to prevent misidentification errors. This ensures that each sample is correctly matched to the patient from whom it was drawn and the tests ordered, maintaining the integrity of the diagnostic process and preventing potentially dangerous mix-ups.
Question 7: What action should be taken if a hematoma forms?
- Continue drawing blood.
- Ignore and proceed.
- Apply pressure and stop the draw (Correct answer)
- Switch to the same site.
Correct answer: Apply pressure and stop the draw
If a hematoma (a bruise caused by blood leaking out of the vein) begins to form during venipuncture, the phlebotomist should immediately stop the blood draw and apply firm pressure to the site. This helps to minimize the size of the hematoma and reduce patient discomfort. Continuing the draw would worsen the condition.
Question 8: How should sharps be disposed of?
- Recap needles before disposal.
- Throw sharps in regular trash.
- Place in sharps container immediately (Correct answer)
- Leave them on tray.
Correct answer: Place in sharps container immediately
Sharps, such as needles and lancets, must be disposed of immediately after use into a designated puncture-resistant sharps container. This practice prevents needlestick injuries to healthcare workers and others, which can transmit bloodborne pathogens. Recapping needles is dangerous and should be avoided.
Question 9: Why is informed consent important in phlebotomy?
- To avoid using sterile gloves.
- To allow unauthorized procedures.
- To ensure patient agrees and understands the procedure (Correct answer)
- To skip documentation.
Correct answer: To ensure patient agrees and understands the procedure
Informed consent in phlebotomy means ensuring the patient understands the procedure, its purpose, potential risks, and has voluntarily agreed to it. This respects patient autonomy and is a legal and ethical requirement, confirming they are aware of what will happen and have given permission for the blood draw.
