from 65/min to 30/min. The child is more lethargic and continues to have subcostal
retractions. What does this change likely indicate?
A. Respiratory distress is unchanged

airway?

about 10 minutes after eating peanuts. What is the most appropriate initial medication
for this child?
A. Nebulized albuterol
B. Epinephrine IM

✔✔8. A mother brings her 7-year-old child to the emergency department. The mother
states that the child has had a fever for the past 4 days and has had little to eat or drink
during the past 24 hours. Your initial impression reveals a lethargic child with increased
respiratory rate and pale color. Heart rate is 160/min, respiratory rate is 38/min, and
blood pressure is 86/48 mm Hg. Capillary refill is 4 seconds. Which of the following is
the most appropriate intervention for this child?
A. Fluid bolus of 10 mL/kg of isotonic crystalloid
B. Fluid bolus of 20 mL/kg of isotonic crystalloid
C. Maintenance fluid infusion of isotonic crystalloid at 10 mL/h
D. Maintenance fluid infusion of 5% dextrose and water at 20 mL/h - ✔✔Fluid bolus of
20 mL/kg of isotonic crystalloid
✔✔9. An intubated 5-year-old child who was in a motor vehicle collision becomes
increasingly more difficult to ventilate. The child has diminished breath sounds and
chest expansion on the right side of the chest, with audible breath sounds and visible
chest expansion on the left. The endotracheal tube insertion depth has not changed.
What is the most appropriate intervention?
A. Deflate the cuff and pull the tube back
B. Perform needle decompression on the right chest
C. Perform needle decompression on the left chest D. Insert a gastric tube - ✔✔Perform
needle decompression on the right chest
