PRELIM: AI Integration (4)

Improve visualization to support successful access

For oncology patients with difficult access, AI vein finders can:

Elevate heel, apply dry cotton, hold until bleeding stops

In neonatal heel puncture, after collection you should:

Disposed in appropriate sharps containers immediately

After capillary collection, sharps should be:

Chelate calcium and preserve cellular integrity for genetic tests

ACD in yellow tubes serves primarily to:

Antiglycolytic agent preserving glucose

Sodium fluoride in gray tubes acts as:

Westergren ESR requiring specific ratio

Buffered sodium citrate in black tubes is optimized for:

Chelating calcium to prevent coagulation

Potassium EDTA (purple/pink/white tops) acts mainly by:

Inhibiting thrombin and thromboplastin activity

Lithium heparin (green/light green) prevents clotting by:

Rapidly clot blood for STAT serum

Thrombin in orange‑top tubes is included to:

Release tourniquet, withdraw needle, apply firm pressure

The best initial step when a hematoma forms during draw is to:

Bright red and pulsatile

Indicators of arterial puncture include blood that is:

Potassium and proteins via hemoconcentration

Excessive tourniquet time may falsely elevate:

Palpation and visual assessment of veins

Before using an AI vein finder, a fundamental manual skill that remains essential is:

Replace the tube in case vacuum was lost

A logical next step if an evacuated tube does not fill is to:

Lower arm/forearm region

The antebrachial vein referred to in the notes is located in:

Stop IV for a short period if allowed and draw distal

When collecting below an IV, one mitigation strategy (per policy) is to:

Leukocytosis and thrombocytosis

The buffy coat thickness increases most with:

Visualize subcutaneous veins

Hemoglobin within RBCs binds NIR light, helping devices to:

Visualize veins in real time for guidance

An AI‑guided robotic needle system often uses ultrasound primarily to:

Successful venipuncture on the first attempt

In AI‑assisted phlebotomy, “first‑stick success” means:

Cost and limited access versus trained human phlebotomists

A practical limitation of robotic venipuncture in routine labs is:

Perpendicular to finger ridges on the lateral side to increase blood flow

For fingerstick, the lancet should be placed:

Increase capillary blood flow and arterialize the sample

Warming the puncture site prior to capillary collection can:

Additive carryover that may alter downstream tests

The order of draw helps minimize:

Cell shrinkage and altered indices due to excess anticoagulant

When using EDTA, an underfilled tube can cause:

Severely burned with limited venous access

A capillary collection is preferred over venipuncture when the patient is:

Needlestick injuries and contamination

Phlebotomy equipment should be organized to prevent:

Posture (supine vs seated)

Which patient factor can physiologically change analyte levels and should be documented?

Gender, Age, Pregnancy

“GAP” in the notes highlights variability due to:

Needle angle outside 15–30 degrees, poor site choice, inadequate antisepsis

In an AI‑assisted training platform, error detection can flag:

Nerve injury and patient pain

Choosing a site near a large nerve bundle increases risk of:

Reduce suction by switching to a smaller vacuum or butterfly with syringe

If a vein collapses during draw, a suitable adjustment is to:

Guide selection and cannulation while still requiring operator skill

AI‑projected vein maps on the skin are intended to:

Professional skill, ethical practice, and compassionate care

Despite AI advances, a non‑negotiable element of clinical hematology practice is:

Enhance vein detection, first‑attempt success, comfort, training, and safety

The overarching impact of AI on venipuncture and skin puncture, per the notes, is to:
