Phlebotomy Procedures and Regulations Quiz

Chlorhexidine is commonly used for skin preparation due to its broad-spectrum antimicrobial properties.

A 20-gauge needle is commonly used for routine venipuncture, balancing patient comfort and blood flow.

The median cubital vein is preferred for venipuncture due to its accessibility, stability, and minimal risk of nerve injury.

The palmar aspect of the hand, particularly the finger pads, is commonly used for fingerstick blood collection due to its rich capillary network.

A 60-degree angle is recommended for needle insertion during routine venipuncture to minimize pain, increase success rates, and avoid vein injury.

The red top tube is often used for glucose testing, as it contains no additives that could interfere with glucose measurements.

Hemoconcentration refers to the increased concentration of red blood cells in the blood, often caused by prolonged tourniquet application.

The recommended order of draw is essential to prevent cross-contamination between tubes and ensure accurate test results.

CLSI provides standardized guidelines for blood specimen collection, processing, and handling to ensure accuracy and safety.

The butterfly needle is used for delicate or difficult veins, minimizing patient discomfort and reducing the risk of vein damage.

A tourniquet is used to increase venous pressure, facilitating blood filling in veins and making them easier to locate for venipuncture.

Hematoma, or localized bleeding under the skin, is a common complication of phlebotomy, often resulting from improper technique or vein injury.

The chain of custody ensures the integrity and security of blood specimens throughout the testing process, crucial for legal and forensic purposes.

The tourniquet is used to temporarily occlude blood flow, making veins more prominent and facilitating blood collection.

EDTA (ethylenediaminetetraacetic acid) is an anticoagulant that binds calcium ions, preventing blood clotting and preserving cell integrity for various tests.

The calcaneus, or heel bone, is the recommended site for heelstick blood collection in infants due to its accessibility and low risk of injury.

The gel separator forms a barrier between serum and cellular components after centrifugation, facilitating serum separation and preventing contamination.

The order of draw minimizes the risk of cross-contamination between blood collection tubes, ensuring accurate test results by preventing additive carryover.

Staining is a crucial step in blood smear preparation, enhancing cell visibility under the microscope for accurate differential cell counts.

Venous reflux occurs when blood flows backward into the vein due to improper needle placement or insufficient pressure during blood collection.
