Resuscitation Test 1

1. What is the first step in the Basic Life Support (BLS) algorithm?

2. Which of the following is the recommended compression depth for adult CPR?

3. When should an automated external defibrillator (AED) be used during CPR?

4. What is the correct ratio of chest compressions to rescue breaths in adult CPR?

5. What is the recommended rate of chest compressions per minute in adult CPR?

What percentage of all deaths from cardiovascular disease is attributed to sudden unexpected cardiac arrests?

Why is CPR often initiated even when resuscitation should not be attempted in some cases?

Declaring an individual dead cannot be done without a time-consuming medical examination
To avoid prolonging myocardial necrosis
There is often uncertainty regarding likelihood of survival and the risks of CPR are low

What is the risk associated with rapid and/or sustained ventricular tachycardia (VT), particularly in the setting of left ventricular dysfunction?

The faster and more sustained a VT, the greater the risk of cardiac arrest.
The faster and more sustained a VT, the greater the risk of cardiac arrest. The risk is highest in those with left ventricular dysfunction.
The risk of cardiac arrest is greater with slow VT.

What is the risk associated with ventricular fibrillation (VF)?

Most cases of VF terminate spontaneously
Roughly 50% of cases of VF terminate spontaneously
VF is highly unlikely to terminate spontaneously and the vast majority progress to cardiac arrest
VF can progress to pulseless electrical activity
