Phlebotomy Test Pediatric Blood Collection

Question 1

What is the maximum recommended blood volume to collect from a neonate weighing 3 kg in a single day?

Accepted Answer

5–10 mL

Answer

For neonates, blood volume is approximately 85–90 mL/kg; daily blood draws should not exceed 5–10% of total blood volume to avoid iatrogenic anemia.

Question 2

Which vein is most commonly used for venipuncture in infants and toddlers under 2 years of age?

Accepted Answer

Dorsal hand veins or scalp veins

Answer

Dorsal hand veins and (in neonates) scalp veins are commonly used for pediatric IV access and blood collection when antecubital veins are inadequate or inaccessible.

Question 3

A phlebotomist is preparing to draw blood from a 5-year-old child. Which communication strategy is MOST effective?

Accepted Answer

Use age-appropriate language, explain what they will feel, and allow them control (e.g., which arm)

Answer

Age-appropriate, honest explanation combined with giving the child choices reduces anxiety and improves cooperation during pediatric blood collection.

Question 4

Which needle gauge is most appropriate for venipuncture in a pediatric patient to minimize pain and hemolysis?

Accepted Answer

23–25 gauge

Answer

23–25 gauge needles are appropriate for pediatric venipuncture, providing adequate blood flow while minimizing pain, trauma, and hemolysis from high shear forces.

Question 5

A newborn requires a blood glucose test and bilirubin level. Which collection method is preferred?

Accepted Answer

Heelstick into micro-collection tubes for both tests

Answer

For newborns, heelstick into appropriate Microtainer tubes is the preferred method for small-volume tests like glucose and bilirubin, avoiding the risks of venipuncture.
