Introduction This NHA Phlebotomy Exam practice format for 2026/2027 reflects a comprehensive competency
assessment designed to evaluate proficiency in blood collection principles for candidates pursuing Certified Phlebotomy
Technician certification. The exam measures knowledge of patient identification, venipuncture/capillary puncture
techniques, order of draw, tube additives, specimen handling, infection control, complication management, special
population considerations, and scenario-based decision-making essential for safe, effective, and compliant phlebotomy
practice. The 75-question format provides extensive coverage of high-yield NHA CPT domains for study, preparation, and
technical mastery purposes. All questions are presented in Multiple Choice Question (MCQ) format with four
answer options (A, B, C, D).
Answer Format All correct answers must be presented in bold and green font, each question must appear in bold
Georgia font, all questions must be MCQ format with answer choices (A, B, C, D), and all rationales explaining phlebotomy
protocols, safety standards, and scenario-based reasoning must be written in italic Georgia font.
1. A phlebotomist enters a patient's room to perform a blood draw. Which of the following is the first and
most critical step in the procedure?
A. Preparing the equipment
B. Selecting the vein
C. Identifying the patient
D. Washing hands
C. Identifying the patient
Rationale: According to CLSI guidelines and NHA standards, correct patient identification is the most critical step to
prevent medical errors. Use at least two unique identifiers (e.g., full name and date of birth).
2. Which of the following additives is found in a light blue-topped tube?
A. EDTA
B. Sodium Citrate
C. Heparin
D. Sodium Fluoride
B. Sodium Citrate
Rationale: Light blue tubes contain sodium citrate, which acts as an anticoagulant by binding calcium. This tube is
primarily used for coagulation studies (PT, PTT).
3. A phlebotomist is preparing to perform a venipuncture on a patient who has had a double mastectomy.
Where should the blood be drawn from?
A. The right arm
B. The left arm
, C. The hand
D. Consult with the physician
D. Consult with the physician
Rationale: In the case of a double mastectomy, lymphostasis can occur in both arms, making them susceptible to infection
and skewed test results. A physician’s order is required to draw from either arm or an alternative site like the feet.
4. Which of the following is the correct order of draw for a venipuncture procedure?
A. Lavender, Green, Red, Light Blue
B. Light Blue, Red, Green, Lavender
C. Red, Light Blue, Lavender, Green
D. Green, Lavender, Light Blue, Red
B. Light Blue, Red, Green, Lavender
Rationale: The CLSI-recommended order of draw prevents additive cross-contamination: Blood Cultures, Light Blue
(Citrate), Serum (Red/SST), Green (Heparin), Lavender (EDTA), and Gray (Oxalate).
5. While performing a venipuncture, the patient begins to seize. What is the phlebotomist's first priority?
A. Finish the draw quickly
B. Call for help and protect the patient from injury
C. Remove the needle and apply pressure
D. Place a tongue depressor in the patient's mouth
C. Remove the needle and apply pressure
Rationale: Safety is paramount. The needle must be removed immediately to prevent injury to the patient or technician.
Once the needle is safe, the phlebotomist should then protect the patient and seek assistance.
6. What is the standard depth for a heel stick on an infant to avoid hitting the calcaneus bone?
A. 1.0 mm
B. 2.0 mm
C. 3.0 mm
D. 4.0 mm
B. 2.0 mm
Rationale: CLSI standards dictate that heel punctures on infants should not exceed 2.0 mm in depth to prevent
osteochondritis or osteomyelitis of the calcaneus (heel bone).
7. A phlebotomist must collect a specimen for a Blood Alcohol Content (BAC) test. Which antiseptic should
be used?
A. 70% Isopropyl Alcohol
B. Povidone-Iodine
C. Soap and water (or non-alcoholic antiseptic)
D. Hydrogen Peroxide
C. Soap and water (or non-alcoholic antiseptic)
Rationale: Using isopropyl alcohol to clean the site for a BAC test can lead to a false-positive result or legal disputes
regarding the accuracy of the blood alcohol level.
8. Which of the following veins is the first choice for venipuncture in the antecubital fossa?
A. Cephalic vein
B. Basilic vein
C. Median cubital vein
D. Brachial vein
C. Median cubital vein
Rationale: The median cubital vein is the preferred site because it is usually large, well-anchored, and further from nerves
and arteries, making it the safest option.
9. When performing a capillary puncture, why is the first drop of blood wiped away?
A. To prevent clotting
B. To remove interstitial fluid contamination
C. To reduce pain for the patient
D. To ensure the tube fills faster
B. To remove interstitial fluid contamination
Rationale: The first drop of blood often contains tissue (interstitial) fluids that can dilute the specimen and interfere with
accurate test results.
10. Which of the following is a symptom of syncope?
A. Extreme thirst
B. Sudden paleness and sweating
C. High blood pressure
D. Increased energy
B. Sudden paleness and sweating
Rationale: Syncope (fainting) is often preceded by pallor (paleness), diaphoresis (sweating), dizziness, and nausea.
