Module 4 - Cardiac Arrest Managment

Question 1

What are the Hs and Ts?

Answer 1

• Hyperkalemia/hypokalemia
• Hypovolemia
• Hydrogen ions (acidosis)
• Hypothermia
• Hypoxia
• Thrombosis (pulmonary or cardiac)
• Toxins (drugs or medications)
• Tamponade (cardiac)
• Tension Pneumonthorax

Question 2

What is the first step in the ACLS cardiac arrest algorithm?

Answer 2

Start CPR and attach defibrillator

Question 3

What are the two shockable rhythms?

Answer 3

Ventricular fibrillation

pulseless ventricular tachycardia

Question 4

After how many shocks can you given amiodarone?

Answer 4

3 shocks

Question 5

What is the dose of epinephrine in a cardiac arrest? And how do you give it?

Answer 5

1 mg IV push every 3-5 minutes

Question 6

What are the amiodarone doses in a cardiac arrest?

Answer 6

1st: 300 mg IV push
2nd: 150 mg IV push

Question 7

If the rhythm is found to be asystole or a PEA, what are you going to do?

Answer 7

CPR and give epinephrine 1 mg every 3-5 minutes, intermittently checking rhythm

Question 8

What are the 3 aspects of post cardiac arrest care?

Answer 8

1) Optimize ventilation and oxygenation
2) cardiovascular stabilization (treat hypotension) and treat reversible cause (ECG)
3) neurological care (temperature control and ICU)

Question 9

What is the first line of treatment for bradycardia?

Answer 9

Atropine 0.5 mg IV bolus q3-5 minutes to a max dose of 3mg

Question 10

What rhythms can adenosine be used for?

Answer 10

regular wide and narrow SVT

Question 11

What is the difference between synchronized cardioversion and defibrillation?

Answer 11

• pulse is required for synchronized cardioversion
• pts rhythm must be synced and it is important where in the rhythm the shock is delivered due to the risk of delivering it during the refractory period and causing a worse arrhythmia

Question 12

What are the dosages of Adenosine?

Answer 12

1st: 6 mg IV rapid push with a 20cc flush immediately after
2nd: 12 mg IV rapid push with a 20cc flush immediately after
