CRNI Pediatric Infusion Therapy Practice Test

Question 1

What is the primary reason pediatric patients are at higher risk for fluid overload during infusion therapy?

Accepted Answer

Smaller total blood volume relative to adults

Answer

Pediatric patients have a smaller total blood volume relative to adults, making even small volume errors potentially dangerous. A few milliliters of excess fluid can represent a significant percentage of their circulating volume, increasing the risk of fluid overload.

Question 2

When calculating maintenance IV fluid rates for a pediatric patient using the Holliday-Segar method, what is the rate for the first 10 kg of body weight?

Accepted Answer

100 mL/kg/day

Answer

The Holliday-Segar formula calculates 100 mL/kg/day for the first 10 kg, 50 mL/kg/day for the next 10 kg, and 20 mL/kg/day for each kg above 20 kg. This is the most widely used method for pediatric maintenance fluid calculations.

Question 3

Which vascular access device is most appropriate for short-term peripheral infusion therapy in a neonate?

Accepted Answer

24-gauge peripheral IV catheter

Answer

A 24-gauge peripheral IV catheter is the most appropriate choice for short-term peripheral infusion in neonates due to their small vessel size. Larger gauge catheters would be too large, and central devices are reserved for longer-term or specialized therapy needs.

Question 4

What is the recommended maximum volume for a single IV push medication in a neonate?

Accepted Answer

1 mL

Answer

In neonates, the recommended maximum volume for a single IV push medication is generally 1 mL to prevent fluid overload and minimize the risk of adverse hemodynamic effects. Larger volumes should be given as short infusions instead.

Question 5

A nurse is preparing to start an IV on a 2-year-old child. Which site is generally preferred for peripheral IV access in this age group?

Accepted Answer

Dorsum of the hand

Answer

The dorsum of the hand is generally the preferred site for peripheral IV access in toddlers because it provides good vein visibility, allows for adequate securing, and leaves the child's arms relatively free for movement. Scalp veins are typically reserved for infants under 9 months.
