1. What is the recommended duration for administering CPR to an
unresponsive infant before activating the emergency response system?
A. 1 minute
B. 2 minutes
C. 3 minutes
D. 5 minutes
Answer: B. 2 minutes
Rationale: For infants and children who are found unresponsive and not breathing
normally, PALS guidelines recommend starting CPR immediately and
performing approximately 2 minutes of high-quality CPR before leaving the child
to activate the emergency response system if alone. This approach prioritizes early
circulation support, which significantly improves survival outcomes.
2. A patient is in cardiac arrest. Ventricular fibrillation has been refractory to
a second shock. Of the following, which drug and dose should be
administered first by the IV/IO route?
A. Epinephrine 1 mg
B. Amiodarone 300 mg
Answer: B. Amiodarone 300 mg
Rationale: In pediatric cardiac arrest, if ventricular fibrillation (VF) or pulseless
ventricular tachycardia (pVT) persists after two defibrillation attempts, amiodarone
is recommended as the first antiarrhythmic. Epinephrine is given early in non-
,shockable rhythms or after the first shock, but amiodarone specifically addresses
refractory VF/pVT.
3. A 5-year-old child is found unresponsive with a heart rate of 30/min and
no palpable pulse. After initiating high-quality CPR and establishing vascular
access, you administer epinephrine. What should be your next step?
A. Continue CPR and reassess the rhythm after 2 minutes.
B. Administer a second dose of epinephrine immediately.
C. Intubate the child to secure the airway before continuing CPR.
D. Check for signs of circulation before continuing with CPR.
Answer: A. Continue CPR and reassess the rhythm after 2 minutes.
Rationale: After administering epinephrine in pediatric cardiac arrest, high-quality
CPR must be continued for 2 minutes before reassessing the rhythm. Interrupting
compressions to reassess or administer drugs too early can reduce coronary and
cerebral perfusion, decreasing the chance of return of spontaneous circulation (ROSC).
4. What is the primary role of epinephrine in pediatric resuscitation during
cardiac arrest?
A. To increase blood pressure and improve coronary perfusion
B. To decrease heart rate and promote relaxation
C. To induce sedation and calm the patient
D. To enhance oxygen delivery to tissues
Answer: A. To increase blood pressure and improve coronary perfusion
Rationale: Epinephrine acts primarily as a vasoconstrictor, increasing systemic
vascular resistance and coronary perfusion pressure. This supports myocardial and
cerebral blood flow during CPR, improving the likelihood of ROSC. It does not directly
calm the patient or enhance oxygenation without concurrent ventilation.
,5. A 7-year-old girl presents with severe wheezing and difficulty breathing
after exposure to a known allergen. She is unable to speak in full sentences
and has a peak flow reading of 50% of her personal best. After administering
oxygen, what is the next appropriate step?
A. Administer albuterol via nebulizer
B. Provide oral corticosteroids
C. Intubate the patient immediately
D. Give antihistamines for allergic reaction
Answer: A. Administer albuterol via nebulizer
Rationale: Severe asthma exacerbation or status asthmaticus in a pediatric patient
should be managed first with rapid-acting bronchodilators (albuterol) via
nebulizer. Oxygen therapy is provided for hypoxemia, while corticosteroids are
adjunctive and antihistamines play a limited role in acute bronchospasm. Intubation is
reserved for impending respiratory failure.
6. What is the recommended method for providing ventilation to a pediatric
patient in respiratory distress?
A. Use a nasal cannula with supplemental oxygen
B. Perform chest compressions at a rate of 100/min
C. Open the airway and provide positive-pressure ventilation using a bag-mask device
D. Administer oral medications to relieve symptoms
Answer: C. Open the airway and provide positive-pressure ventilation using a bag-
mask device
Rationale: For pediatric patients with inadequate breathing or respiratory
arrest, bag-mask ventilation is preferred as it ensures oxygenation and ventilation
until advanced airway management can be established. Nasal cannula alone is
insufficient, and chest compressions are only indicated for cardiac arrest.
7. If one person is performing bag-mask ventilation, the best way to provide
effective ventilation is to use the:
A. A-C clamp technique
B. E-C clamp technique
, C. B-C clamp technique
D. D-C clamp technique
Answer: B. E-C clamp technique
Rationale: The E-C clamp technique allows one rescuer to maintain a proper mask
seal using two hands (forming an "E" with the fingers and a "C" with the thumbs and
index fingers), while squeezing the bag with the other hand. This maximizes tidal
volume and prevents air leaks.
8. In a scenario where a pediatric patient is in cardiac arrest, how would you
modify your CPR technique if you notice inadequate chest recoil during
compressions?
A. Increase the compression rate
B. Ensure the patient is on a flat surface
C. Adjust your hand position to allow for better recoil
D. Administer epinephrine immediately
Answer: C. Adjust your hand position to allow for better recoil
Rationale: Full chest recoil is essential during CPR to allow the heart to refill with
blood between compressions. Adjusting hand placement improves recoil and ensures
effective perfusion. Simply increasing compression rate without correcting recoil
reduces blood flow effectiveness.
9. Explain why endotracheal drug administration is considered the least
desirable method during resuscitation in pediatric patients.
A. It is less effective than intravenous administration
B. It requires specialized equipment that is not always available
C. It can lead to complications such as airway obstruction
D. All of the above
Answer: D. All of the above
Rationale: Endotracheal drug administration is less predictable in dosing and
absorption than IV/IO routes. Additionally, it requires proper equipment and skill, and
