HEARTCODE PALS EXAM VERSION 1
Whenever a child has an abnormal heart rate of rhythm, what
must be done quickly? - ANSWER-Determine if the arrhythmia
is causing hemodynamic instability or other signs of
deterioration.
What is the priority in initially managing arrhythmias? -
ANSWER-Support the airway, breathing and circulation
What are the causes of secondary bradycardia? - ANSWER--
Hypoxia
-Acidosis
-Hypotension
-Hypothermia
-Drugs
,2|Page
What are the electrocardiographic characteristics of
bradycardia? - ANSWER--Heart rate slow compared with
normal heart rate for age
-P wave and QRS complex may be unrelrated
-QRS complex may be narrow or wide
What is a THIRD-degree atrioventricular block? - ANSWER-
None of the atrial impulses conduct to the ventricles
What is a FIRST-degree atrioventricular block - ANSWER-A
prolonged PR interval representing slowed conduction through
the atrioventricular node
Why do children with cardiac tamponade improve temporarily
with fluid administration? - ANSWER-Fluids augment cardiac
and tissue perfusion until pericardial drainage can be performed
What is the initial dose of epinephrine in the treatment of
symptomatic bradycardia? - ANSWER-0.01 mg/kg IV/IO
,3|Page
In which patients would bradycardia be an expected finding and
not be considered problematic? - ANSWER--A healthy child
who is sleeping
This is due to reduced metabolic demand
-A well-conditioned athlete
This is due to high stroke volume and increased vagal tone
What is the IV/IO dose of atropine for pediatric bradycardia? -
ANSWER-0.02 mg/kg
What should your next steps be? - ANSWER--Maintains a
patent airway
-Apply cardiac monitor to identify rhythm and monitor pulse,
blood pressure, and oximetry
-Complete the initial and primary assessment
During the initial assessment, you find that the infant is
unresponsive and has an HR of less than 60/min.
What should be your next action? - ANSWER-Begin CPR
, 4|Page
CPR has been ongoing and IV access has been established. A
pulse and rhythm check are done. He has the rhythm.
What intervention would be most appropriate at this time? -
ANSWER-Administer epinephrine
What is the proper dosing for epinephrine (IV/IO)
administration during CPR? - ANSWER--0.01 mg/kg IO/IV
-Repeat every 3 to 5 minutes.
After 2 more minutes of CPR, you notice the patient is moving
and his skin color improves. his vital signs are 114 RR 8/min
and temperature 37.9 C (100.2 F). The infant is still slow to
respond but is moving.
What should be the next steps for this patient? - ANSWER--
Continue oxygen
-Obtain expert consultation
-Support ABC's
-Identify and treat underlying causes
What clinical findings may be presented in a child with a
tachyarrhythmia? - ANSWER--Palpitations
