Paramedics Exam Cardiology and Resuscitation 4

Question 1

A patient with atrial fibrillation has a ventricular rate of 140 bpm and a BP of 88/60 mmHg with altered mental status. What is the most appropriate intervention?

Accepted Answer

Synchronized cardioversion

Answer

Unstable atrial fibrillation with hemodynamic compromise requires immediate synchronized cardioversion to restore sinus rhythm.

Question 2

Which ECG finding is most associated with a hyperacute (very early) STEMI before ST elevation develops?

Accepted Answer

Peaked, tall T waves in the affected leads

Answer

Hyperacute T waves—tall, peaked, and asymmetric—are the earliest ECG sign of myocardial ischemia, appearing before ST elevation.

Question 3

A patient has a pulseless rhythm that appears as a rapid, completely disorganized waveform on the monitor. What is the immediate treatment?

Accepted Answer

Deliver unsynchronized defibrillation immediately

Answer

Ventricular fibrillation is treated with immediate unsynchronized defibrillation, as there is no organized rhythm to synchronize with.

Question 4

In the management of suspected cardiac tamponade in a pulseless patient, which intervention is definitive?

Accepted Answer

Pericardiocentesis

Answer

Pericardiocentesis, the needle drainage of blood from the pericardial sac, is the definitive treatment for cardiac tamponade.

Question 5

When performing two-rescuer adult CPR, at what rate should chest compressions be delivered?

Accepted Answer

100-120 compressions per minute

Answer

Current AHA guidelines recommend chest compressions at a rate of 100-120 per minute for optimal coronary and cerebral perfusion during CPR.
