PALS Bradycardia With a Pulse 3

Question 1

A neonate presents with bradycardia and poor tone after birth. Supplemental oxygen does not improve the HR above 60 bpm. What action should be taken?

Accepted Answer

Begin chest compressions

Answer

In neonates, if HR remains below 60 bpm despite adequate ventilation and oxygenation, chest compressions should be started.

Question 2

Transcutaneous pacing is being considered for a 10-year-old with symptomatic bradycardia refractory to medications. Which statement is TRUE about transcutaneous pacing in children?

Accepted Answer

Adequate analgesia and sedation should be provided during pacing

Answer

Transcutaneous pacing is painful; sedation and analgesia are essential when using it in conscious pediatric patients.

Question 3

A 3-year-old with Down syndrome presents with bradycardia and signs of respiratory distress. Which initial step has the highest priority?

Accepted Answer

Providing high-flow oxygen and supporting ventilation

Answer

In PALS, the primary intervention for symptomatic bradycardia is always airway and oxygenation before any pharmacologic therapy.

Question 4

Which dose of epinephrine is used via the IV/IO route for bradycardia in the PALS algorithm?

Accepted Answer

0.01 mg/kg (1:10,000 solution)

Answer

PALS recommends IV/IO epinephrine at 0.01 mg/kg using the 1:10,000 (0.1 mg/mL) solution for bradycardia.

Question 5

A school-age child on beta-blocker therapy for hypertension presents with bradycardia. Which drug may be particularly useful in this situation?

Accepted Answer

Glucagon

Answer

Glucagon can overcome the negative chronotropic effects of beta-blockers and is a useful antidote for beta-blocker toxicity-induced bradycardia.
