Question 1

A 4-year-old weighing 16 kg requires maintenance IV fluids. Using the Holliday-Segar method, what is the correct hourly fluid rate?

Accepted Answer

52 mL/hr

Answer

Holliday-Segar: 100 mL/kg for first 10 kg (1000 mL) + 50 mL/kg for next 10 kg (300 mL) = 1300 mL/24 hr ≈ 52 mL/hr for a 16 kg child.

Question 2

When selecting a peripheral IV catheter for a neonate, which gauge is most appropriate to minimize vascular trauma?

Accepted Answer

24 gauge

Answer

A 24-gauge catheter is preferred for neonates because their small, fragile vessels require the smallest gauge that still allows adequate flow.

Question 3

A child receiving a vesicant chemotherapy infusion via a peripheral IV reports burning at the site. The nurse notes swelling and pallor. What is the priority intervention?

Accepted Answer

Stop the infusion immediately and aspirate residual drug

Answer

Vesicant extravasation requires immediate infusion cessation and aspiration of residual drug before initiating site-specific antidote protocols.

Question 4

Which blood product requires a leukocyte-reduction filter when transfused to a pediatric patient who has had prior febrile non-hemolytic transfusion reactions?

Accepted Answer

Packed red blood cells

Answer

Leukoreduced packed red blood cells are indicated for patients with prior febrile non-hemolytic reactions, as white blood cells are the primary cause of these reactions.

Question 5

A 7-year-old with cystic fibrosis is prescribed tobramycin. Which parameter is most critical to monitor during IV aminoglycoside therapy in pediatric patients?

Accepted Answer

Serum creatinine and drug trough levels

Answer

Aminoglycosides are nephrotoxic and ototoxic; monitoring serum creatinine and trough levels ensures therapeutic dosing while preventing accumulation-related toxicity.
