When collecting blood from a neonate, the total volume drawn should not exceed what percentage of the patient's estimated blood volume in any single episode?
Answer: 3–5%
Single-episode blood draws should not exceed 3–5% of total blood volume to prevent significant hemodynamic compromise in neonates.
A phlebotomist notices a pediatric patient's arm has an IV infusion running. Where should blood be drawn?
Answer: From the opposite arm or below the IV site in the same arm only as a last resort
Drawing from the opposite arm avoids IV fluid dilution of the specimen; if only one arm is available, draw below the IV site with the infusion stopped for 2 minutes.
What is the primary purpose of the 'transitional hold' or 'kangaroo care' position during neonatal blood collection?
Answer: To use skin-to-skin contact for pain relief and calming during the procedure
Skin-to-skin (kangaroo care) contact between parent and neonate significantly reduces pain responses (heart rate, crying, cortisol) during blood collection procedures.
A 6-year-old patient with a known diagnosis of hemophilia A requires a blood draw. What special consideration applies?
Answer: Use a small butterfly needle with careful technique and apply prolonged pressure afterward
Hemophilia A (factor VIII deficiency) impairs clotting; careful technique to minimize trauma and prolonged post-draw pressure are essential to prevent hematoma.
Which vein in the antecubital fossa is considered the SAFEST for venipuncture in older children and adolescents?
Answer: Median cubital vein
The median cubital vein is the preferred site because it is large, well-anchored (doesn't roll), and located away from major nerves and arteries, making it the safest choice.
A phlebotomist is caring for a 3-year-old with autism spectrum disorder (ASD) who becomes extremely distressed during blood draws. Which approach is MOST likely to improve the experience?
Answer: Collaborate with the care team for individualized preparation including desensitization visits and sensory accommodations
Children with ASD benefit from individualized preparation including gradual desensitization, sensory accommodations, and structured routines developed with the care team before the procedure.
A phlebotomist collects blood from a 2-year-old and observes the specimen appears hemolyzed in the tube. Before reporting results, the phlebotomist should:
Answer: Notify the laboratory and physician that hemolysis may affect certain test results, and recollect if necessary
Hemolysis can significantly alter test results; the laboratory must be notified to assess which tests are affected and whether recollection is needed to avoid incorrect clinical decisions.
Which of the following is TRUE regarding the use of topical anesthetic (EMLA cream) for pediatric venipuncture?
Answer: It requires application 45–60 minutes before the procedure under an occlusive dressing
EMLA cream requires 45–60 minutes under occlusive dressing to achieve adequate dermal anesthesia; immediate application provides no benefit.
