Question 11

For V-fib/V-tach, administer:

A. Dextrose
B. Amiodarone
C. Sodium bicarbonate
D. Narcan

Answer 11

B. Amiodarone

300 mg, repeat 150 mg q 2min

Question 12

Sodium bicarbonate is only administered in what arrest rhythm?

A. Pulseless V-tach
B. V-tach
C. PEA/Asystole

Answer 12

C. PEA/Asystole

Question 13

What are the indications of Sodium Bicarbonate in PEA/Asystole?

Answer 13

• Known TCA overdose
• Known ASA overdose
• Chronic renal failure

Question 14

MOA of bicarbonate in renal failure cardiac arrest.

Answer 14

Used to neutralize lactic acidosis 2/2 to arrest. With cardiopulmonary arrest, two things happen:

1) Respiratory arrest - increasing PaCO2 due to no exhalation
2) Cardiac arrest - no transport of deoxygenated blood to pulmonary circulation

• Cells switch to anaerobic metabolism, decreasing blood pH/increasing acidosis

Question 15

In adults, both sodium bicarbonate and calcium chloride are given for adult cardiac arrest. In what situations is each used?

Answer 15

Calcium: cardiac arrest with no ROSC after two rounds of epnephrine with renal failure Hx.

Bicarbonate: ONLY Asystole/PEA with TCA/ASA overdose or renal failure Hx.
