Basic Life Support and Defibrillation (BLSD)

What is the first step in Basic Life Support (BLS)?. Check for responsiveness. Call for help. Open the airway. Check for breathing.

What does 'DRS ABCD' stand for in BLS?. Danger, Response, Send for help, Breathing, CPR, Defibrillation. Danger, Response, Send for help, Airway, Breathing, CPR, Defibrillation. Danger, Resuscitation, Support, Breathing, CPR, Defibrillation. Danger, Response, Stabilize, Breathing, CPR, Defibrillation.

When checking for breathing, how long should you observe the person?. 5-10 seconds. 10-15 seconds. 15-30 seconds. 30-60 seconds.

What is the recommended compression rate for adult CPR?. 60-80 compressions per minute. 80-100 compressions per minute. 100-120 compressions per minute. 120-140 compressions per minute.

What is the recommended depth for chest compressions on an adult?. About 1 inch (2.5 cm). About 2 inches (5 cm). About 3 inches (7.5 cm). About 4 inches (10 cm).

What is the correct compression-to-ventilation ratio for adult CPR?. 15:2. 30:2. 5:1. 10:1.

What is the purpose of chest recoil during CPR?. To increase the depth of compressions. To allow the heart to refill with blood. To prevent rib fractures. To provide oxygen to the lungs.

When using an Automated External Defibrillator (AED), what is the first step after turning it on?. Attach the pads. Clear the person. Follow the voice prompts. Perform chest compressions.

Where should the AED pads be placed on an adult?. Upper right chest and lower left side. Upper left chest and lower right side. Center of the chest and center of the back. Both on the front of the chest.

What should you do if the AED advises a shock?. Continue CPR. Immediately administer the shock. Ensure no one is touching the person. Check for breathing again.

What should you do if the AED does NOT advise a shock?. Turn off the AED. Continue CPR. Check for a pulse. Wait for further instructions.

What is the primary goal of BLS?. To immediately restart the heart. To maintain circulation and oxygenation until advanced care arrives. To provide pain relief to the person. To assess for injuries.

What are signs of choking in an adult?. Coughing forcefully, speaking, grasping throat. Inability to cough forcefully, speak, or breathe; clutching the throat. Wheezing and rapid breathing. Low heart rate.

What is the first action for a conscious choking adult?. Perform abdominal thrusts (Heimlich maneuver). Encourage them to cough. Give them water to drink. Call for an ambulance.

What is the correct procedure for abdominal thrusts (Heimlich maneuver) on a conscious choking adult?. Stand behind the person, place arms around their waist, make a fist, and perform quick upward thrusts. Stand in front of the person and perform downward thrusts. Sit the person down and perform chest thrusts. Have the person lean forward and perform back blows.

If an adult becomes unconscious while choking, what should you do next?. Continue abdominal thrusts. Immediately start CPR. Call emergency services. Try to remove the object with your finger.

What is the recommended compression technique for infants (under 1 year) CPR?. Two hands encircling the chest. Two fingers on the center of the chest. One hand on the center of the chest. Thumb encircling the chest.

What is the recommended compression depth for an infant?. About 1 inch (2.5 cm). About 1.5 inches (4 cm). About 2 inches (5 cm). About 2.5 inches (6 cm).

What is the compression-to-ventilation ratio for infant CPR?. 15:2. 30:2. 5:1. 10:1.

How should you open the airway of an infant?. Head-tilt/chin-lift. Sniffing position (slight head tilt). Jaw thrust. Do not open the airway.

What is ventricular fibrillation (VF)?. A normal heart rhythm. A chaotic electrical activity in the ventricles, causing the heart to quiver instead of pump blood. A blockage of blood flow to the heart muscle. A slow and regular heart rhythm.

What is the most common initial rhythm in cardiac arrest that is treatable with defibrillation?. Asystole. Pulseless electrical activity (PEA). Ventricular fibrillation (VF). Bradycardia.

When should chest compressions be paused?. Only when administering rescue breaths. During AED analysis and shock delivery. When checking the person's pulse. All of the above.

What is the recovery position?. Lying flat on the back. Lying on the stomach. Lying on the side with legs bent. Sitting upright.

When should you place an unresponsive person who is breathing normally into the recovery position?. Immediately after starting CPR. When the person starts to vomit. If you are alone and need to leave the person to get help. When the person is breathing normally and does not require CPR.
