Cardiac Arrest

Question 1

What is the recommended rate at which cardiac compressions should be preformed?

Answer 1

100-120

Question 2

Once an advanced airway is properly inserted, what is the recommended ventilation rate during CPR?

Answer 2

1 breath every 6 seconds

Question 3

Part 1 - You are transporting a 68-year-old male patient for emergent dialysis. During transport, he becomes hypotensive and unresponsive. His 12-lead is as shown. Shortly after capturing the 12-lead, your patient arrests. What cause of cardiac arrest is most likely?

Answer 3

Hyper-K

Question 4

Part 2 - What medication should you administer based on your diagnosis from Question 3?

Answer 4

Calcium Chloride

Question 5

You are called for a patient who has a stab wound to the left chest. EMS initially reported a pulse, but when you go to assess, the pulse is now gone. The causes of arrest that you should consider in this patient are tension pneumothorax, pericardial tamponade, hemorrhagic shock.
True or False?

Answer 5

True

Question 6

Incomplete chest recoil during compressions causes reduced venous return, increased ICP, increased intrathoracic pressure and ultimately leads to reduced cerebral and cardiac perfusion.
True or False?

Answer 6

True

Question 7

Answer 7

Magnesium 2g
ABC

Epi 1 mg

Question 8

Myocardial function may require up to 72 hours to return to baseline with return of circulation after cardiac arrest.
True or False?

Answer 8

True

Which of the following statements is TRUE regarding hypoxic brain injury post-cardiac arrest? Select ALL that apply.

Answer 9

Cerebral autoregulation is disrupted for hours to days following return of cerebral perfusion.

Question 10

What is the preferred method for temperature monitoring in a hypothermic patient?

Answer 10

Esophageal

Question 11

A hypothermic patient in cardiac arrest should be transferred to an ECMO center for re-warming except in which of the following cases?

Answer 11
