Resuscitation Test 1

9 question(s) with answers and explanations.

Question 1

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

• ✓ A. Check for responsiveness
• ○ B. Open the airway
• ○ C. Assess breathing
• ○ D. Start chest compressions

Question 2

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

• ✓ A. 2 inches
• ○ B. 1 inch
• ✓ C. 3 inches
• ○ D. 4 inches

Question 3

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

• ○ A. After 5 cycles of CPR
• ○ B. Before starting chest compressions
• ○ C. Only if a healthcare professional is present
• ✓ D. As soon as it becomes available

Question 4

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

• ○ A. 15:2
• ✓ B. 30:2
• ○ C. 5:1
• ○ D. 10:1

Question 5

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

• ○ A. 60-80
• ✓ B. 100-120
• ○ C. 140-160
• ○ D. 180-200

Question 6

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

• ○ 20%
• ○ 30%
• ✓ 50%
• ○ 70%

Question 7

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

Question 8

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.

Question 9

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
