PALS Precourse Self-
Assessment Test Exam 2026
Brand New
Which oxygen delivery system most reliably delivers a high (90% or
greater) concentration of inspired oxygen to a 7-year-old child? --
Verified--Solution----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? --
Verified--Solution----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
, 2 | Page
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? -- Verified--
Solution----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
A 9-year-old boy is agitated and leaning forward on the bed in obvious
respiratory distress. The patient is speaking in short phrases and tells you
that he has asthma but does not carry an inhaler. He has nasal flaring,
severe suprasternal and intercostal retractions, and decreased air
movement with prolonged expiratory time and wheezing. You
administer 100% oxygen by a nonrebreathing mask. His SpO, is 92%.
Which medication do you prepare to give to this patient? -- Verified--
Solution----Albuterol
You are part of a team attempting to resuscitate a child with ventricular
fibrillation cardiac arrest. You delivered 2 unsynchronized shocks. A
team member established I access, so you give a dose of epinephrine,
0.01 mg/kg IO. At the next rhythm check, persistent ventricular
fibrillation is present. You administer a 4-J/kg shock and resume CPR.
Which drug and dose should be administered next? -- Verified--
Solution----Amiodarone 5 mq/kg IO
You are called to help treat an infant with severe symptomatic
bradycardia (heart rate 66/min) associated with respiratory distress. The
bradycardia persists despite establishment of an effective airway,
oxygenation, and ventilation. There is no heart block present. Which is
the first drug you should administer? -- Verified--Solution----
Epinephrine
