, Identify the rhythm.
- correct answer Asystole
Identify the rhythm.

Which statement is correct about endotracheal drug administration during resuscitative efforts for
pediatric
patients?
- correct answer It is the least desirable route of administration
Which oxygen delivery system most reliably delivers a high (90% or greater) concentration of inspired
oxygen to a 7-year-old child?
- correct answer Nonrebreathing face mask
Paramedics are called to the home of a 1-year-old child. Their initial assessment reveals a child who
responds only to painful stimuli and has irregular breathing, faint central pulses, bruises over the
abdomen, abdominal distention, and cyanosis. Bag-mask ventilation with 100% oxygen is initiated. The
child's heart rate is 36/min. Peripheral pulses cannot be palpated, and central pulses are barely
palpable. The cardiac monitor shows sinus bradycardia. Two-rescuer CPR is started. Upon arrival to the
emergency department, the child is intubated and ventilated with 100% oxygen, and IV access is
established. The heart rate is now 150/min with weak central pulses but no distal pulses. Systolic blood
pressure is 74 mm Hg. Which intervention should be provided next?
- correct answer Rapid bolus of 20 mL/kg of isotonic crystalloid
A previously healthy infant with a history of vomiting and diarrhea is brought to the emergency
department by her parents. During your assessment, you find that the infant responds only to painful
stimulation. The infant's respiratory rate is 40 breaths per minute, and central pulses are rapid and
weak. The infant has good bilateral breath sounds, cool extremities, and a capillary refill time of more
than 5 seconds. The infant's blood pressure is 85/65 mm Hg, and glucose is 30 mg/dL (1.65 mol/L). You
administer 100% oxygen via face mask and start an IV. Which treatment is the most appropriate for this
infant?
- correct answer Administer a bolus of isotonic crystalloid 20 mL/kg over 5 to 20 minutes, and also give
D2;W 2 to 4 mL/kg IV
