PEARS PEARS Post-Resuscitation Care and Monitoring 2 — Questions and Answers
Question 1: Which monitoring tool provides the most reliable continuous assessment of cardiac output trends during post-resuscitation care?
- Continuous pulse oximetry and arterial blood pressure monitoring (Correct answer)
- Intermittent manual blood pressure only
- Urine dipstick every 4 hours
- Skin color assessment alone
Correct answer: Continuous pulse oximetry and arterial blood pressure monitoring
Continuous pulse oximetry combined with arterial line blood pressure provides real-time perfusion data essential for guiding post-resuscitation management.
Question 2: After pediatric ROSC, which lab value best reflects end-organ perfusion adequacy?
- Serum lactate (Correct answer)
- Serum sodium
- Hemoglobin A1c
- Platelet count
Correct answer: Serum lactate
Serum lactate reflects tissue oxygen delivery; elevated lactate indicates inadequate perfusion and guides resuscitation efforts.
Question 3: A post-ROSC child develops new-onset seizures. What is the immediate management priority?
- Treat seizures promptly with anticonvulsants and assess for underlying cause (Correct answer)
- Observe and wait for spontaneous resolution
- Increase IV fluid rate only
- Decrease supplemental oxygen
Correct answer: Treat seizures promptly with anticonvulsants and assess for underlying cause
Post-resuscitation seizures increase cerebral metabolic demand and worsen outcomes; prompt anticonvulsant therapy and cause identification are essential.
Question 4: Which urine output target indicates adequate renal perfusion in a post-ROSC pediatric patient?
- ≥1 mL/kg/hour (Correct answer)
- < 0.5 mL/kg/hour
- > 5 mL/kg/hour
- Urine output is not monitored post-resuscitation
Correct answer: ≥1 mL/kg/hour
A urine output of ≥1 mL/kg/hour suggests adequate renal perfusion and is a key clinical indicator of resuscitation effectiveness.
Question 5: What is the recommended approach to ventilator settings immediately after intubation in a post-ROSC pediatric patient?
- Titrate to achieve normocarbia and appropriate SpO2; avoid hyperventilation (Correct answer)
- Set rate at maximum to ensure CO2 clearance
- Provide 100% FiO2 indefinitely
- Allow PaCO2 to rise to 60 mmHg
Correct answer: Titrate to achieve normocarbia and appropriate SpO2; avoid hyperventilation
Targeting normocarbia and SpO2 94%–99% avoids secondary brain injury from both hypoxia and excessive CO2 changes.
Question 6: A pediatric patient is hemodynamically unstable after ROSC with signs of poor perfusion. What is the first-line intervention?
- IV fluid bolus of isotonic crystalloid (10–20 mL/kg) (Correct answer)
- Immediate high-dose epinephrine infusion
- Oral rehydration therapy
- Chest compressions restart
Correct answer: IV fluid bolus of isotonic crystalloid (10–20 mL/kg)
An isotonic crystalloid bolus of 10–20 mL/kg is the first-line treatment for post-ROSC hemodynamic instability before escalating to vasopressors.
