Question: compression to breath ratio children with 1 rescuer
Answer: 30:2
Question: 2 rescuer compression to breath ratio?
Answer: 15:2
Question: Initial impression of a 2-year old girl shows her to be alert with
mild breathing difficulty during inspiration and pale skin color.
On primary assessment, she makes high pitched inspiratory
sound (mild stridor) when agitated; otherwise, intercoastal
retractions. Lung auscultation reveals transmitted upper airway
sounds with adequate distal breath sounds bilaterally. Which is
the most appropriate initial intervention for this child?
Answer: humidified oxygen as tolerated
Question: Which statement is correct about use of calcium chloride in
pediatric?
Answer: Routine administration is not indicated during cardiac arrest
Question: Which statement is correct about endotracheal drug
administration during resuscitative efforts for pediatric
patients?
Answer: It is the least desirable route of administration
Question: You are a part of a team attempting to resuscitate a child with
ventricular fibrillation cardiac arrest. You delivered 2
unsynchronized shocks. A team member established IO
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?
Answer: Amiodarone 5 mg/kg
Question: You are called to help treat an infant with severe symptomatic
bradycardia (HR 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?
Answer: Epinephrine
Question: Which statement is correct about the effects of epinephrine
during attempted resuscitation?
Answer: Epinephrine stimulates spontaneous contractions when asystole is present
, Question: Paramedics are called to the home of a 1yo 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 mmHg. Which
intervention should be provided next?
Answer: Rapid bolus of 20 ml/kg of isotonic crystalloid
Question: 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
intercoastal retractions, and decreased air movement with
prolonged expiratory time and wheezing. You administer 100%
oxygen by a NRB mask. His SpO2 is 92%. Which medication do
you prepare to give to this patient?
Answer: Albuterol
Question: A previously healthy infant with a history of vomiting and
diarrhea is brought to the ER by her parents. During your
assessment, you find that the infant responds only to painful
stimulation. The infant's RR is 40/min, and central pulses are
rapid and weak. The infant has good bilateral breath sounds,
cool extremities, and a capillary refill time of ore than 5
seconds. The infant's blood pressure is 85/65 mmHg, and
glucose is 30 mg/dL (1.56 mmol/L). You administer 100%
oxygen via facemsk and start an IV. Which treatment is the
most appropriate for this infant?
Answer: Administer a bolus of isotonic crystalloid 20 ml/kg over 5-20 minutes, and also give
D25W to 4 ml/kg IV
Question: How can rescuers ensure that they are providing effective
breaths when using a bag-mask device?
Answer: By observing the chest rise with each breath
Question: You need to provide rescue breaths to a child victim with a
pulse. What is the appropriate rate for delivering breaths?
Answer: 1 breath every 3 to 5 seconds
