Scalp veins are an acceptable and commonly used peripheral IV site in neonates when extremity veins are not accessible.

Question 2

What is the maximum recommended dwell time for a peripheral IV catheter in a pediatric patient?

Accepted Answer

72–96 hours

Answer

Current guidelines recommend rotating peripheral IV sites every 72–96 hours in pediatric patients, or sooner if signs of complications arise.

Question 3

A 3-year-old presents with dehydration and multiple failed peripheral IV attempts. Which vascular access device is most appropriate as an immediate bridge?

Accepted Answer

Intraosseous device

Answer

Intraosseous access provides rapid, reliable vascular access in pediatric emergencies when peripheral IV attempts have failed.

Question 4

Which of the following is a contraindication to intraosseous (IO) insertion in a pediatric patient?

Accepted Answer

Fracture in the target bone

Answer

A fracture in the target bone is a contraindication to IO insertion at that site because fluid may extravasate through the fracture.

Question 5

When calculating catheter-to-vein ratio for pediatric peripheral IVs, what is the maximum recommended ratio to minimize thrombosis risk?

33%

Answer

The catheter should occupy no more than 33% of the vessel lumen to allow adequate blood flow and reduce thrombophlebitis risk.
