For which of the following would it be appropriate to move an adult victim who might need CPR?When the adult victim is in a dangerous environment
Several colleagues are nearby. After determining that the scene is safe, you assess the victim for responsiveness and breathing. There is no response when you gently tap and speak to the victim. You note that he is not breathing. The next thing you need to do isSend someone to activate the emergency response system and get the AED.
Which of the following victims needs CPR?A victim who is unresponsive with no breathing (or no normal breathing) and no pulse
After you send someone to activate the emergency response system and get an AED, you and 2 other colleagues lower the victim gently to the floor. You would thenCheck for a pulse.
The proper location to check for a pulse in an adult victim is at thecarotid artery of the neck.
The victim has no pulse. You begin CPR at a compression rate ofat least 100 per minute and a compressions-to-breaths ratio of 30:2.
The recommended depth of chest compressions for an adult victim is at least2 inches (5 cm).
Why is it important to compress to the appropriate depth during CPR?Adequate depth of compression is needed to create blood flow during compressions.
Complete chest recoil contributes to CPR success byallowing the heart to refill with blood between compressions.
While you provide compressions and count aloud, a colleague is giving breaths. To open the airway for this victim, your colleague will use thehead tilt-chin lift technique.
To reduce rescuer fatigue during team CPR, compressor roles should be switched about every5 cycles.
You and several colleagues are with an adult male victim who collapsed while entering the hospital. He is unresponsive, is not breathing, and has no pulse. You and a colleague perform 2-rescuer CPR until another colleague arrives with an AED. She kneels at the victim’s side, places the AED next to the victim, and opens the case. What should she do next?Turn on the AED
The AED analyzes the victim’s cardiac rhythm and reports “No shock advised.” The victim is still unresponsive and not breathing. Next, you shouldresume CPR, beginning with chest compressions.
After 2 minutes of CPR, the AED prompts you to analyze again. The next step is toconfirm that no one is touching the victim, allow the AED to analyze, and deliver a shock if prompted by the AED.
This time, the AED advises you to shock the victim. After you clear the victim and deliver the shock, you shouldimmediately restart CPR, beginning with chest compressions
You see a 6 year old boy collapse. The child has no pulse. You should nowbegin cycles of chest compressions and breaths at a ratio of 30:2.
The recommended depth of compressions for a child isat least one third the depth of the chest, or approximately 2 inches.
The proper location to perform a pulse check for a child isat the carotid artery of the neck or the femoral artery of the leg.
Your colleague arrives with the AED, and a third rescuer arrives with a bag and mask. The colleague managing the AED opens the device and begins taking out the pads. The third rescuer uses the bag and mask, and you and your colleague begin 2-rescuer child CPR with the correct compressions-to-breaths ratio of15:2
Your colleague finds that there are only standard adult pads in the AED case. He shoulduse the standard adult pads.
In 2-rescuer CPR for an adult or child 8 years of age or older, the first rescuer begins chest compressions while the second rescuermaintains an open airway and gives breaths.
You and your colleague perform the next steps of BLS for an infant in the correct order bychecking for both responsiveness and breathing, and then sending the colleague to activate the emergency response system and get the AED while you check for a brachial pulse and start CPR if there is no pulse.
Where should a rescuer attempt to locate the brachial pulse in an infant?Inside the upper arm, between the elbow and shoulder
There is no pulse, and your colleague has not returned with the AED. You begin chest compressions. As a lone rescuer, you start chest compressions by using the 2-finger technique, providing30 compressions, just below the nipple line, at a rate of at least 100 compressions per minute, with a compressions-to-breaths ratio of 30:2.
More colleagues arrive at the scene, bringing the AED. You and a colleague are now ready to begin 2-rescuer CPR while the pads are being placed. Which of the following is the preferred chest compression technique for 2-rescuer CPR in an infant?2 thumb-encircling hands
To perform the 2 thumb-encircling hands technique, you wrap your fingers around the infant’s chest, and place your thumbson the lower half of the breastbone.
The recommended depth of chest compressions for an infant isat least one third the depth of the chest, approximately 1.5 inches (4 cm).
Which of the following correctly compares characteristics of chest compressions in adults with those in infants and children?Compression depth: for adults, at least 2 inches; for infants/children, at least one third the depth of the chest
You and your partner know the rescue breaths he is delivering for the infant victim are effective whenthe chest rises visibly.
You and your partner provide 2-rescuer CPR for the infant, using a ratio of15:2.
You are working at your desk when you hear the receptionist call for help. You enter the waiting room to find a 63-year-old man slumped in a chair. When should you ensure that the scene is safe?When you first see the potential victim
The scene is safe. You would nextcheck for a response (gently tap the victim and ask, “Are you all right?”) and check for breathing.
The victim does not answer or respond in any way and is not breathing. You would nextactivate the emergency response system and get the AED (you can send someone to do these things).
After you identify an unresponsive victim with no breathing (or no normal breathing) and no pulse, chest compressions should be initiated within10 seconds.
After activating the emergency response system and sending someone to get the AED, you shouldcheck for a carotid pulse.
The victim has a pulse. The emergency resuscitation cart (crash cart) arrives. Your next step should be toopen his airway by using the head tilt-chin lift technique.
You open the airway by using the head tilt-chin lift technique. You would nowgive 1 breath every 5-6 seconds by using a bag and mask.
Which of the following correctly states the proper technique for delivering mouth-to-mouth breaths?The rescuer opens the airway, seals his or her mouth over the victim’s mouth, pinches the victim’s nose closed, and gives each breath for about 1 second each while watching for the chest to rise.
Gastric inflation is more likely to occur if the rescuergives breaths too quickly or with too much force.
You are performing rescue breathing for a victim who is not breathing but has a pulse. Your initial rescue breaths did not go in. You shouldreopen the airway with the head tilt-chin lift technique and attempt an additional breath.
What is the best way for a rescuer to know that a rescue breath for an adult victim is effective?The chest rises visibly.
You are able to give breaths that produce visible chest rise for the victim of respiratory arrest (not breathing but with a pulse). Your next step is tocontinue rescue breathing, checking the pulse about every 2 minutes.
After you perform several minutes of rescue breaths and checking for a pulse, additional help and equipment, including advanced airway management, arrives. You determine that the victim no longer has a pulse and the rescuers need to begin CPR with an advanced airway in place.
Which of the following options lists the correct rates for compressions-to-breaths for 2-rescuer CPR in the presence of an advanced airway?
Compress at a rate of at least 100 per minute, 1 breath every 6 to 8 seconds.
As you enter the room, the child collapses. When you examine the child, you find her very limp, pale, unresponsive, and not breathing. The scene is safe, and you send your assistant to activate the emergency response system and get the AED and emergency equipment while youcheck for a pulse for no more than 10 seconds.
The child has a pulse and a heart rate of 64/min. Your next step is togive breaths without chest compressions.
When administering breaths by using a bag-mask device for a child who is not breathing but does have a pulse, the rescuer shouldgive breaths at a rate of 1 breath every 3 to 5 seconds.
The volume provided with each breath should beenough to cause visible chest rise.
During bag-mask ventilation, which of the following is recommended to minimize the risk of gastric inflation?Give a breath with only the force and volume needed to see the chest rise.
Each rescue breath should be delivered over a period of1 second.
If an unresponsive infant is not breathing and has a heart rate of 53 beats per minute and signs of poor perfusion despite oxygenation and ventilation with a bag and mask, which of the following should you perform?Both chest compressions and breaths
If an adult is eating and suddenly coughs and cannot breathe, talk, or make any sounds, you should ask the adult if she is choking. If she nods “yes,” tell her you are going to help and give abdominal thrusts.True
Which of the following are signs of a severe block in the airway in an adult or child who is responding?No coughing, not able to talk
What is the best way to relieve severe choking in a responsive adult?Perform abdominal thrusts
A choking adult becomes unresponsive while you are doing abdominal thrusts for severe choking. You ease the victim to the floor and send someone to activate your emergency response system. What should you do next?Begin CPR without a pulse check. When you open the airway, look for and remove the object (if seen) before giving rescue breaths.
What is the best action to relieve severe choking in a responsive infant?Begin cycles of up to 5 back slaps and up to 5 chest thrusts.
