Answer 1

No1. Any organized rhythm without a pulse is defined as pulseless electrical activity (PEA).

True

But, there is some condition that you should not be confused with PEA. You always take an ECG and check the apical pulse to confirm PEA.

Because there is a very febal peripheral pulse even carotid pulse in some cases like a patient in cardiogenic shock.

No 2. Synchronized cardioversion is appropriate for treating an unknown wide complex tachycardia.

True

But, If it is hemodynamically unstable. If the patient is hemodynamically stable then go for Injection Cordarone or Adenosine.

No 3. The right side of the heart is responsible for pulmonary circulation.

True.

Right Atrium pumps blood to the right ventricle, then RV pumps blood to the pulmonary artery, then blood goes to the lungs and comes back to the heart by pulmonary vein.

No 4. Any bradycardia less than 60 beats per minute is a pathologic event.

False

Any bradycardia is not a pathogenic event, because athletes normally having bradycardia(heart rate less than 60) during rest.

No 5. The most effective treatment for ventricular fibrillation is defibrillation.

Yes

Defibrillation and CPR are very effective during ventricular fibrillation.

No 5. Therapeutic hypothermia should be considered in the comatose adult after cardiac arrest.

True

Therapeutic hypothermia helps to reduce brain damage. So, it can be helpful to regain consciousness for comatose patients after cardiac arrest.

No 6. An individual should be cleared-Ñ prior to a shock only when convenient.

False

An individual should be cleared every time prior to the shock.

No 7. Nausea in conjunction with chest pain may be indicative of myocardial ischemia.

True

It may be indicating myocardial ischemia but it may be a symptom of acid reflux disease.

No 8. Symptomatic bradycardia and poor perfusion may degrade into cardiac arrest.

True

It may be cause cardiac arrest, but not always.

No 9. Urgent defibrillation is essential for survival in the management of acute strokes.

False

Defibrillation is not required in strokes. Thrombolysis may be essential management in strokes.
