Phlebotomy Test Pediatric Blood Collection 2

Question 1

A toddler requires venipuncture but is extremely uncooperative. Which approach is BEST?

Accepted Answer

Involve the parent in positioning and comforting while a second person assists in immobilization as needed

Answer

Involving the parent for comfort and having a trained assistant for safe immobilization is the recommended approach, minimizing trauma while safely completing the collection.

Question 2

Microtainer tubes are color-coded the same as adult venipuncture tubes. Which Microtainer tube would be used for a neonatal chemistry panel (BMP)?

Accepted Answer

Gold (serum separator with clot activator)

Answer

Gold-top Microtainer tubes (serum separator with clot activator) are used for chemistry panels, just as gold/SST tubes are used in adult venipuncture for chemistry testing.

Question 3

What does 'iatrogenic anemia' mean in the context of neonatal blood collection?

Accepted Answer

Anemia resulting from excessive blood removal by medical testing

Answer

Iatrogenic anemia in neonates refers to anemia directly caused by repeated blood draws for laboratory testing, which removes significant blood volume from their small total blood volume.

Question 4

When a pediatric patient has difficult veins, which site is acceptable for venipuncture in children under 12 months?

Accepted Answer

Scalp veins (superficial temporal or frontal veins)

Answer

Scalp veins are used in neonates and young infants when peripheral limb veins are inaccessible, as they are visible and well-supported for needle access.

Question 5

A phlebotomist observes petechiae on a child's arm after applying a tourniquet. This finding suggests:

Accepted Answer

Possible thrombocytopenia (low platelet count) or capillary fragility

Answer

Petechiae (tiny red/purple pinpoint hemorrhages) appearing under a tourniquet indicate thrombocytopenia or capillary fragility—this is a clinically significant unexpected finding.
