1Obtaining Blood Samples (including which tubes are used for specific tests)

42% of exam

Blood is drawn using proper technique and the correct tubes.

  • Venipuncture is the standard method; capillary draws are used for small samples.
  • The order of draw prevents cross-contamination of additives.
  • Tube tops are color-coded (e.g., lavender/EDTA for CBC, light blue for coagulation, red for serum).
  • Correct tube selection ensures accurate results.

2Specimen Collection & Processing

16% of exam

Specimens must be collected, labeled, and handled correctly.

  • Verify patient identity with two identifiers before collection.
  • Label tubes at the bedside immediately.
  • Follow proper centrifuging, storage, and transport.
  • Errors (hemolysis, clots, mislabeling) compromise results.

3Time Management & Assignment Organization

8% of exam

Phlebotomists manage multiple patients and priorities.

  • Prioritize STAT and timed draws (e.g., glucose tolerance).
  • Organize routes and supplies efficiently.
  • Manage fasting and collection schedules.
  • Good organization reduces errors and patient wait time.

4Professional Communications

4% of exam

Clear, calm communication helps anxious patients.

  • Explain the procedure and answer questions.
  • Use empathy to reduce fear, especially in children.
  • Communicate clearly with nurses and lab staff.
  • Maintain confidentiality and professionalism.

5Clerical Skills & Duties

4% of exam

Accurate records keep the lab running smoothly.

  • Enter and verify patient and test information correctly.
  • Use laboratory information systems (LIS) and requisitions.
  • Track specimens and maintain logs.
  • Attention to detail prevents costly errors.

6Safety Standards & Procedures

10% of exam

Safety protects both patient and phlebotomist.

  • Follow standard precautions and use PPE.
  • Dispose of sharps in approved containers to prevent needlesticks.
  • Know bloodborne pathogen and OSHA rules.
  • Proper technique reduces injury and infection risk.

7Legal, Ethical, & Professional Considerations

8% of exam

Phlebotomy is governed by law and ethics.

  • Obtain informed consent before drawing blood.
  • Protect privacy under HIPAA.
  • Work within scope of practice and document accurately.
  • Understand liability and the chain of custody for legal specimens.

8Terminology, Anatomy, & Physiology

8% of exam

Understanding the body guides safe blood collection.

  • Know the veins of the arm (median cubital, cephalic, basilic).
  • Understand blood composition — cells and plasma.
  • Use correct medical terminology for tests and anatomy.
  • This knowledge prevents nerve and artery injury.
