What is the first medication you should administer in a pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF) arrest?✔✔Epinephrine 1 mg IV/IO every 3-5 minutes.
How do you confirm proper endotracheal tube placement during an ACLS emergency?✔✔Use waveform capnography (continuous ETCO₂ monitoring) and auscultate for bilateral breath sounds while observing chest rise.
What is the primary goal of post-cardiac arrest care?✔✔Optimize perfusion to the brain and heart while identifying and treating the underlying cause of the arrest.
When should you consider terminating resuscitation efforts in an out-of-hospital cardiac arrest?✔✔If there is no ROSC (return of spontaneous circulation) after 20 minutes of effective ACLS interventions with no reversible causes identified.

What is the recommended dose of amiodarone for recurrent ventricular fibrillation (VF) or pulseless VT?✔✔300 mg IV/IO push, with a second dose of 150 mg if needed.
How do you manage symptomatic bradycardia if atropine is ineffective?✔✔Initiate transcutaneous pacing or administer an epinephrine or dopamine infusion.
What is the immediate treatment for unstable tachycardia with a pulse?✔✔Synchronized cardioversion, starting at the appropriate energy level based on the rhythm (e.g., 50-100 J for atrial fibrillation).
What is the key difference between primary and secondary cardiac arrest?✔✔Primary cardiac arrest is due to a cardiac cause (e.g., VF, VT), while secondary arrest results from respiratory or metabolic failure (e.g., hypoxia, hyperkalemia).
How should you treat a patient with acute coronary syndrome (ACS) and ongoing chest pain despite nitroglycerin?✔✔Administer morphine for pain control, beta-blockers (if no contraindications), and consider urgent reperfusion therapy (PCI or fibrinolytics). 2 / 3

What is the first step in managing a patient with a suspected stroke within the window for thrombolytics?✔✔Obtain a non-contrast CT scan to rule out hemorrhage and determine eligibility for alteplase.
What is the most critical electrolyte to correct in a cardiac arrest patient with suspected hyperkalemia?✔✔Calcium (calcium gluconate or calcium chloride) to stabilize myocardial membranes, followed by insulin-glucose and sodium bicarbonate.
When should you consider therapeutic hypothermia (targeted temperature management) after ROSC?✔✔For comatose adult patients with ROSC after out-of-hospital VF arrest or in-hospital/out-of- hospital arrest with non-shockable rhythms.
What is the primary treatment for torsades de pointes?✔✔Magnesium sulfate 1-2 g IV push and correcting underlying causes (e.g., hypokalemia, QT- prolonging drugs).
