What is the correct dose of lidocaine for pulseless VT/VF when amiodarone is unavailable?
Answer: 1–1.5 mg/kg IV push
Lidocaine is dosed at 1–1.5 mg/kg IV push as an alternative to amiodarone for pulseless VT/VF.
Calcium gluconate is indicated during cardiac arrest caused by which electrolyte abnormality?
Answer: Hyperkalemia
Calcium gluconate (or calcium chloride) stabilizes cardiac membranes in hyperkalemia-induced cardiac arrest.
Which statement about amiodarone administration for cardiac arrest is correct?
Answer: The second dose is 150 mg IV push if VF persists
The second dose of amiodarone in refractory VF/pulseless VT is 150 mg IV push after the initial 300 mg dose.
A patient receives epinephrine 1 mg IV for cardiac arrest. When should the next dose be given?
