Pediatric Resuscitation – Pediatric Advanced Life
Support (PALS) Practice Questions with Answer
Review (2024|2025)
1. Describe how MgSO4 should be prepared for infusion in an emergency
situation.
MgSO4 should be given undiluted directly into the bloodstream.
MgSO4 should be diluted in water for injection.
MgSO4 should be diluted in a 5 percent dextrose solution to a
concentration of 20 percent or less.
MgSO4 should be mixed with saline for infusion.
2. You are using ETCO2 through a King airway during CPR. You suddenly
see an increase in your ETCO2 reading from 25mmhg to 55mmhg. A
sharp increase in ETCO2 is a sign of:
You may have return of spontaneous circulation
This patient is now brain dead
Oxygen is no longer being delivered to the patient
King airway became dislodged
3. In a scenario where a child presents with cardiogenic shock and has
received 10 mL/kg of isotonic fluids, what would be the next appropriate
step if their systolic blood pressure remains below the 5th percentile for
age?
,Increase the fluid rate to 15 mL/kg immediately.
Wait for 30 minutes before reevaluating.
Start CPR without further assessment.
Administer vasoactive medications as indicated and consider
further fluid resuscitation.
, 4. In a scenario where a child presents with gasping and cyanosis, what
immediate actions should a clinician take based on the findings of
bradypnea and irregular respiration?
Monitor the child’s vital signs for 30 minutes before taking action.
Initiate emergency resuscitation protocols, including effective
CPR and oxygen support.
Wait for the child to regain normal breathing before intervening.
Administer oral medications to stabilize the child.
5. Hypotensive Guideline for infants
Systolic BP less than 70 mmHg
Systolic BP less than 70 + (2 x age in years) mmHg
Systolic BP less than 60 mmHg
Systolic BP less than 90 mmHg
6. What are the physical findings associated with airway obstruction that
indicate potential cardiopulmonary failure?
Stridor, stertor, drooling, and/or severe retractions
Normal breath sounds and clear airway
Coughing, wheezing, and/or cyanosis
Rapid breathing, chest pain, and/or fever
7. Describe the significance of supporting airway, breathing, and circulation
in the context of pediatric advanced life support.
The initial management should prioritize patient comfort over vital
signs.
It is important to focus on medication administration first.
