PARAMEDIC
Q1. You respond to a pediatric respiratory arrest. The child's Broselow tape reads YELLOW. Which weight range does this correspond to, and what does it help determine?
A. Yellow = 10–11 kg; provides weight-based medication doses and equipment sizes
B. Yellow = 15–18 kg (Blue zone is 10–11 kg)
C. Yellow = 12–14 kg; only used for IV dosing
D. Yellow = 8–9 kg; matches Purple zone
The Broselow tape Yellow zone corresponds to approximately 10–11 kg. The tape estimates weight by the child's height and provides color-coded medication doses, tube sizes, and equipment sizes for that weight range.
PARAMEDIC
Q2. Per King County Medic One protocol, a Broselow GREEN zone pediatric patient (approximately 24 kg) is in respiratory failure requiring RSI. What endotracheal tube (ETT) size is typically associated with the green zone?
A. 6.0–6.5 mm ETT (cuffed or uncuffed)
B. 5.0 mm ETT
C. 7.0 mm ETT (adult size)
D. 4.5 mm ETT
Broselow Green zone (23–29 kg) typically uses a 6.0–6.5 mm uncuffed or 6.0 mm cuffed ETT. The tape provides the recommended tube size printed in the corresponding color zone, eliminating the need for manual calculation under pressure.
PARAMEDIC
Q3. King County EMS responds to a 16 kg child in decompensated shock from sepsis. What is the correct IV fluid bolus, and how many times can it be repeated?
A. 320 mL NS (20 mL/kg), may repeat with reassessment after each bolus
B. 160 mL NS (10 mL/kg), give only once
C. 500 mL NS (fixed amount)
D. 320 mL NS, given only once
King County / PALS standard: 20 mL/kg NS IV/IO as initial bolus. For 16 kg: 20 × 16 = 320 mL. This may be repeated (20 mL/kg each time) up to 60–80 mL/kg total with reassessment after each bolus. Reassess perfusion, breath sounds, and mental status after each.
