PALS Algorithms Questions And
Answers With Verified Solutions 100%
Correct!!!
Cardiac arrest (pulseless), first steps - ANSWER✔✔ call for help; start CPR;
attach O2; attach defibrillator
Cardiac arrest (pulseless), first decision point - ANSWER✔✔ rhythm shockable?
VT/VF -> Yes; asystole/PEA -> No
Cardiac arrest (pulseless), first shock dose (and subsequent) - ANSWER✔✔ 2
J/kg, increase by 2 J/kg each subsequent dose to max 10 J/kg
Cardiac arrest (pulseless), shockable algorithm - ANSWER✔✔ CPR; rhythm
check ASAP, shock and treat known/likely causes; CPR 2 minutes; rhythm
check+shock; CPR+epinephrine 2 minutes (consider ETT); rhythm check+shock;
CPR+amiodarone 2 minutes (treat reversible causes empirically); rhythm
check+shock; then repeat 2 minutes cycles of CPR+ alternating epi/amio with
shocks between med doses
Cardiac arrest (pulseless), non-shockable algorithm - ANSWER✔✔ CPR; rhythm
check ASAP, identify non-shockable rhythm; CPR+epi 2 minutes (consider ETT);
rhythm check; CPR 2 minutes (treat reversible causes); rhythm check; CPR+epi 2
minutes (consider ETT); CPR with rhythm check every 2 minutes, epi every 4
minutes (after alternating rhythm checks)
Cardiac arrest (pulseless), compression quality indicators - ANSWER✔✔ >1/3 of
AP diameter, >100 BPM, complete chest recoil, minimize interruptions, change
compressors frequently; goal ETCO2 >10
, Cardiac arrest (pulseless), compression:breath ratio - ANSWER✔✔ 15:2 if no ETT
(30:2 in adults or single rescuer); 8-10 breaths per minute if ETT
Cardiac arrest (pulseless), drug doses - ANSWER✔✔ epinephrine 0.01 mg/kg IV
bolus (0.1mL/kg 1:10,000); epinephrine 0.1 mg/kg Et bolus (0.1mL/kg 1:1000);
amiodarone 5 mg/kg IV bolus, may give second dose
Reversible causes of arrest - ANSWER✔✔ Hypovolemia, Hypoxia, Hydrogen
ions, Hyper/hypokalemia, Hypoglycemia, Hypothermia, Tension pneumothorax,
Tamponade cardiac, Toxins, Thrombosis pulmonary/coronary, Trauma
Epinephrine, cardiac arrest dose - ANSWER✔✔ 0.01 mg/kg IV (0.1 mL/kg
1:10,000); 0.1 mg/kg ET (0.1 mL/kg 1:1000); repeat every 3-5 minutes
Amiodarone, cardiac arrest (VF/VT) dose - ANSWER✔✔ 5 mg/kg IV bolus,
maximum 300 mg; may give second dose (up to 15 mg/kg/d or 2.2 g/d?)
Bradycardia with a pulse and poor perfusion, first steps - ANSWER✔✔ ABCs;
maintain airway, assist if needed; O2; monitor HR, SpO2, BP; IV/IO access; ECG
if available
Bradycardia with a pulse and poor perfusion, first decision point - ANSWER✔✔
cardiopulmonary compromise continues despite correcting airway/breathing
issues? No: support ABCs, address cause; Yes: evaluate HR
Bradycardia with a pulse and poor perfusion, second decision point -
ANSWER✔✔ cardiopulmonary compromise continues despite correcting
airway/breathing issues, now evaluate HR: if <60, start CPR, give epinephrine,
atropine, consider pacing, treat underlying causes
