A 3-year-old presents with drooling, high fever, tripod positioning, and muffled voice. Which action should the nurse AVOID?
Answer: Performing a throat examination with a tongue depressor
In suspected epiglottitis, throat examination or any distressing procedure can precipitate complete airway obstruction; the airway must be secured in a controlled OR setting first.
What is the correct formula for estimated endotracheal tube size (uncuffed) in a child over 2 years of age?
Answer: (Age in years / 4) + 4
The standard formula for uncuffed ETT size in children over 2 years is (age in years ÷ 4) + 4, though cuffed tubes one size smaller are increasingly preferred in PICUs.
A 5-year-old post-extubation develops stridor and increased work of breathing within 1 hour. The MOST appropriate initial intervention is:
Answer: Racemic epinephrine nebulization and IV dexamethasone
Post-extubation stridor due to subglottic edema responds to nebulized racemic epinephrine (rapid onset) and IV dexamethasone (to reduce inflammation) before considering re-intubation.
Which ventilator mode delivers a guaranteed tidal volume while limiting peak inspiratory pressure in pediatric patients?
Answer: Volume-guaranteed (VG) mode
Volume-guaranteed mode delivers a set tidal volume while automatically adjusting pressure to the minimum required, protecting against volutrauma and pressure injury.
A 10-year-old with cystic fibrosis is admitted with a pulmonary exacerbation. Which combination is standard initial therapy?
Answer: IV antibiotics targeting Pseudomonas plus airway clearance therapy
CF pulmonary exacerbations require IV antibiotics with anti-pseudomonal coverage (e.g., tobramycin + piperacillin-tazobactam) combined with aggressive airway clearance to improve outcomes.
In a child with acute hypoxemic respiratory failure, which oxygenation index (OI) value meets criteria for pediatric ARDS (PARDS)?
Answer: OI of 10
According to PALICC criteria, an OI ≥ 8 (or OSI ≥ 7.5) meets the oxygenation threshold for mild PARDS; OI ≥ 16 indicates moderate PARDS.
