Which medication is the first-line antiplatelet agent given to patients with suspected ACS?
Answer: Aspirin 324 mg chewed
Aspirin 324 mg chewed is the first-line antiplatelet agent in suspected ACS due to its rapid absorption and thromboxane inhibition.
A patient with wide-complex tachycardia and a pulse is hemodynamically unstable. What is the priority intervention?
Answer: Synchronized cardioversion
Hemodynamically unstable tachycardia requires immediate synchronized cardioversion to restore organized rhythm.
What does a Killip Class IV classification indicate in a myocardial infarction patient?
Answer: Cardiogenic shock with high mortality
Killip Class IV indicates cardiogenic shock, associated with the highest mortality among MI patients.
Which finding differentiates pericarditis from MI on an ECG?
Answer: Diffuse saddle-shaped ST elevation across multiple leads
Pericarditis causes diffuse saddle-shaped ST elevation in most leads, unlike the localized ST elevation seen in MI.
Which vasopressor is preferred in cardiogenic shock when systolic BP is below 70 mmHg?
Answer: Norepinephrine
Norepinephrine is the preferred vasopressor in severe cardiogenic shock with profound hypotension due to its alpha and beta effects.
An AMLS provider identifies a patient with third-degree AV block and bradycardia with altered mental status. What is the immediate treatment?
Answer: Transcutaneous pacing
Complete heart block with hemodynamic compromise requires transcutaneous pacing as immediate stabilization while awaiting transvenous pacing.
