Sample Questions and Answers

Which vein is typically the first choice for routine venipuncture?

A. Basilic vein
B. Cephalic vein
C. Median cubital vein
D. Radial vein

Correct Answer: C. Median cubital vein

Explanation:
The median cubital vein is considered the primary choice for routine venipuncture because of its size, stability, and accessibility. It lies in the antecubital fossa and is usually well anchored, making it less likely to roll during needle insertion. Compared to the basilic vein, which is close to nerves and arteries, and the cephalic vein, which can be more difficult to palpate, the median cubital vein provides the safest and most efficient option. Selecting the correct vein minimizes patient discomfort and reduces the risk of complications such as hematoma or nerve injury. Proper vein selection also ensures adequate blood flow and specimen quality.

What is the recommended angle of needle insertion for venipuncture using an evacuated tube system?

A. 5–10 degrees
B. 15–30 degrees
C. 45–60 degrees
D. 60–90 degrees

Correct Answer: B. 15–30 degrees

Explanation:
The recommended angle for venipuncture is between 15 and 30 degrees to allow smooth entry into the vein without puncturing through the opposite wall. An angle that is too shallow may cause the needle to slide along the skin without entering the vein, while a steeper angle increases the risk of penetrating through the vein and causing hematoma formation. Maintaining the correct angle also helps reduce patient discomfort and ensures a steady blood flow into the collection tube. Proper positioning and technique improve specimen integrity and reduce the need for repeat attempts, which enhances patient safety and satisfaction.

Which tube should be drawn first during a routine venipuncture using evacuated tubes?

A. Lavender-top tube
B. Green-top tube
C. Light blue-top tube
D. Blood culture bottles

Correct Answer: D. Blood culture bottles

Explanation:
Blood culture bottles are always drawn first when ordered because they require strict aseptic technique to prevent contamination. Collecting them first reduces the risk of introducing additives or skin contaminants from other tubes into the culture sample. After blood cultures, the order of draw typically proceeds to light blue, serum tubes, heparin tubes, EDTA tubes, and glycolytic inhibitor tubes. Following the correct order of draw ensures accurate test results by preventing cross-contamination of additives between tubes. Adhering to this sequence is essential for maintaining specimen quality and patient safety in diagnostic testing.

A patient begins to feel faint during venipuncture. What is the phlebotomist’s immediate action?

A. Continue the draw quickly
B. Remove the needle and apply pressure
C. Ask the patient to stand up
D. Leave the patient alone

Correct Answer: B. Remove the needle and apply pressure

Explanation:
If a patient feels faint or shows signs of syncope during venipuncture, the phlebotomist must immediately remove the needle, activate safety devices, and apply pressure to the site. Patient safety is the top priority. The patient should be assisted into a safe position, such as lying down or sitting with their head lowered, to prevent injury from falling. Continuing the draw could result in complications if the patient loses consciousness. Monitoring the patient and reporting the incident according to facility protocol ensures proper documentation and helps prevent future occurrences.

What is the purpose of a tourniquet during venipuncture?

A. To sterilize the site
B. To slow arterial blood flow
C. To increase venous filling
D. To reduce patient pain

Correct Answer: C. To increase venous filling

Explanation:
A tourniquet is applied to temporarily restrict venous blood flow while allowing arterial flow to continue. This causes veins to become more prominent and easier to locate and access. Proper application improves vein visibility and palpability, making venipuncture more efficient. However, the tourniquet should not remain in place for more than one minute, as prolonged application can cause hemoconcentration and alter test results. Correct use of a tourniquet ensures optimal specimen collection while minimizing discomfort and preventing inaccurate laboratory values.

Which additive is found in a lavender-top tube?

A. Sodium citrate
B. Heparin
C. EDTA
D. Potassium oxalate

Correct Answer: C. EDTA

Explanation:
Lavender-top tubes contain EDTA (ethylenediaminetetraacetic acid), an anticoagulant that binds calcium to prevent blood clotting. EDTA is commonly used for hematology tests such as complete blood counts (CBC), differential counts, and blood smears. It preserves cellular components and maintains morphology for accurate microscopic analysis. Using the correct additive tube is essential because improper tube selection can compromise test results. EDTA tubes must be gently inverted after collection to ensure proper mixing and prevent clot formation that could invalidate laboratory testing.

What is the correct order of draw after blood cultures and light blue tubes?

A. EDTA tubes
B. Serum tubes
C. Gray tubes
D. Lavender tubes

Correct Answer: B. Serum tubes

Explanation:
After blood cultures and light blue sodium citrate tubes, serum tubes are collected next in the order of draw. This includes red-top and gold-top (SST) tubes. Drawing serum tubes before anticoagulant tubes prevents additive carryover that could interfere with clotting tests or other assays. Proper order of draw ensures specimen integrity and reliable test outcomes. Deviating from the sequence may lead to contamination of samples with additives, resulting in inaccurate laboratory values and possible misdiagnosis.

When should a phlebotomist label blood specimens?

A. Before entering the patient’s room
B. After leaving the patient area
C. Immediately after collection at bedside
D. At the end of the shift

Correct Answer: C. Immediately after collection at bedside

Explanation:
Specimens must be labeled immediately after collection and in the presence of the patient. This ensures proper identification and reduces the risk of mislabeling, which can lead to serious medical errors. Labels should include patient name, identification number, date, time of collection, and phlebotomist initials. Labeling at the bedside confirms that the specimen belongs to the correct patient and complies with safety and accreditation standards. Delayed labeling increases the risk of specimen rejection and can compromise patient care.

Which condition increases the risk of hematoma formation during venipuncture?

A. Using a small needle
B. Applying pressure after removal
C. Puncturing through the vein
D. Selecting the median cubital vein

Correct Answer: C. Puncturing through the vein

Explanation:
A hematoma forms when blood leaks into surrounding tissues, often due to puncturing through the vein or failing to apply adequate pressure after needle removal. If the needle passes through the vein or slips out during collection, blood can accumulate under the skin, causing swelling and bruising. Proper technique, including correct needle angle and vein stabilization, helps prevent hematomas. Applying firm pressure after venipuncture and instructing patients not to bend their arm also reduces the risk. Preventing hematomas is essential for patient comfort and maintaining venous integrity.

Which test requires a fasting specimen?

A. Complete blood count
B. Lipid panel
C. Blood culture
D. Coagulation test

Correct Answer: B. Lipid panel

Explanation:
A lipid panel typically requires fasting for 8–12 hours to obtain accurate measurements of cholesterol and triglycerides. Eating before the test can temporarily increase triglyceride levels and affect overall lipid values, potentially leading to misinterpretation. Phlebotomists must verify fasting status and document any deviations before collection. Proper patient preparation ensures reliable laboratory results and supports accurate clinical decisions. Clear instructions and communication with patients are essential to maintain specimen integrity and avoid unnecessary repeat testing.

Which PPE is required when there is potential exposure to blood?

A. Gloves only when requested
B. Gloves for all collections
C. Mask only
D. No PPE needed

Correct Answer: B. Gloves for all collections

Explanation:
Standard precautions require phlebotomists to wear gloves during all blood collection procedures due to potential exposure to bloodborne pathogens. Gloves act as a protective barrier against contaminants such as hepatitis B, hepatitis C, and HIV. Additional PPE, such as face shields or gowns, may be required if splashing is anticipated. Following infection control guidelines protects both healthcare workers and patients. Proper hand hygiene before and after glove use further reduces the risk of cross-contamination and ensures compliance with safety standards.

What is the best site for capillary puncture in an adult?

A. Earlobe
B. Index fingertip center
C. Side of middle or ring finger
D. Thumb

Correct Answer: C. Side of middle or ring finger

Explanation:
For adult capillary puncture, the lateral side of the middle or ring finger is preferred because it has adequate blood flow and fewer nerve endings compared to other fingers. Avoiding the center of the fingertip reduces discomfort and the risk of bone injury. The thumb and index finger should not be used due to thicker skin and increased sensitivity. Proper site selection and technique ensure adequate specimen volume and minimize patient discomfort. Correct capillary collection supports accurate test results for point-of-care testing.

A patient with polycythemia requires coagulation testing. Why is proper anticoagulant ratio especially critical in this case?

A. Polycythemia lowers RBC count
B. High hematocrit alters plasma volume and citrate ratio
C. It improves clotting
D. No special consideration is needed

Correct Answer: B. High hematocrit alters plasma volume and citrate ratio

Explanation:
In polycythemia, elevated hematocrit reduces plasma volume in the tube. Standard sodium citrate volume may become excessive relative to plasma, falsely prolonging PT or aPTT. In such cases, citrate volume adjustment may be required according to laboratory protocol to maintain accurate coagulation results.
