BLS study questions
when performing CPR for a child, the rescuer should compress the chest by using 2 fingers. T or F
F. for a child, the compression technique is the same as for an adult. the rescuer should use 2 hands (heel of one hand with the heel of the other hand on top of the first hand). for a very small child, 1 handed compressions may be used to achieve the desired compression depth.
for an unresponsive child who has a pulse but is not breathing, deliver 1 breath every 6 seconds. T or F
F. for rescue breathing given to infants and children, give 1 breath every 3-5 seconds, or about 12 to 20 breaths per minute.
adult AED pads should never be used on an infant. T or F
F. Adult AED pads may be used on an infant if pediatric pads with a dose attenuator or manual defibrillator is not available.
when giving breaths to a victim by using a pocket mask, the rescuer would deliver each breath over 2 seconds and with just enough force to make the chest rise. T or F
T. each breath should be delivered over 1 second, enough to make the victims chest rise.
after the AED delivers a shock, what should the rescuers do next? a. resume CPR, starting with chest compressions b. complete a pulse check c. give 2 breaths d. clear the victim for another analysis
a. after the AED gives the shock, rescuers should resume CPR immediately, beginning with chest compressions.
a man sitting at a table in the cafeteria stands up suddenly, clutching, his throat with his thumb and fingers. the rescuer interprets this as the universal sign for chocking and goes over to help. which actions would be appropriate for the rescuer to do? select all that apply. A. ask the man if he is chocking B. encourage the man not to cough C. no immediate action is required, so just continue to monitor the mans condition. D. use abdominal thrusts E. give back slaps F. perform chest thrusts G. begin CPR if the man becomes unresponsive.
A, D, G. the man is experiencing a severe airway obstruction. the rescuer should ask the man if he is chocking and then take steps to immediately relieve the obstruction by using abdominal thrusts, repeating thrusts until the object is expelled or the man becomes unresponsive. if the man becomes unresponsive, the rescuer should shout for help, gently lower the man to the ground, and begin CPR, staring with chest compressions.
which rescuer is delivering breaths correctly with a BVM device? A. Deliver each breath over 1 second, watching for chest rise. B. Deliver 2 breaths over 1 second, using force.
A. breaths should be delivered over 1 second, with just enough force to produce visible chest rise. rescuers should avoid excessive ventilation. pause about 1 second between each breath. actually seeing the chest rise with each breath is the best way to ensure that breaths are effective.
a rescuer arrives at he side of an adult victim and suspects an opioid associated life threatening emergency. the victim is unresponsive and not breathing normally but has a pulse. which action should the rescuer do next? A. give 1 breath every 5 to 6 seconds. B. administer naloxone per local protocol
A. for a suspected opioid associated life threatening emergency in a victim who is unresponsive and not breathing normally but does have a pulse, the rescuer should give 1 breath every 5 to 6 seconds in an adult, and every 3 to 5 seconds in a child or infant. then if local protocol allows, the rescuer may give naloxone. but the rescuer should not delay breaths to give naloxone.
an infant is unresponsive and not breathing but has a strong pulse. EMS has been notified. there is no barrier device readily available. when attempting to deliver breaths by using the mouth to mouth and nose technique, the rescuer notices that the chest does not rise. what should be the most appropriate next step? A. repeat the head tilt chin lift and try to give a breath that makes the chest rise. B. begin chest compressions immediately C. wait for EMS to arrive and assist further D. press deeply into the soft tissue under the chin alleviate a possible airway block
A. to deliver breaths by using the mouth to mouth and nose technique, maintain a head tilt chin lift to keep the airway open. then place your mouth over the infants mouth and nose and create an airtight seal, and blow into the infants nose and mouth (pausing to inhale between breaths), just enough to make the chest rise with each breath. if the chest does not rise, repeat the head tilt chin lift to reopen the airway, and try to give a breath that makes the chest rise. it may be necessary to move the infants head through a range of positions to provide effective breaths. when the airway is open, give breaths that make the chest rise.

B. give 1 breath over 2 seconds C. if the chest does not rise with your breath, attempt the jaw thrust maneuver D. take a very deep breath and ensure that a large volume of air is delivered.
A. to deliver mouth to mouth breaths, after opening the victims airway with a head tilt chin lift, pinch the nose closed with the thumb and index finger. next, take a regular (not deep) breath, and seal the lips around the victims mouth, creating an airtight seal, then deliver 1 breath over 1 second, watching the chest rise.
which signs indicate that a person has a severe airway obstruction? select all that apply. A. forceful coughing B. no coughing C. some wheezing between breaths D. clutching at the throat with the thumb and fingers E. being unable to speak F. skin turning blue
B, D, E, F. signs of a severe airway obstruction include clutching the throat with the thumb and fingers to make the universal chocking sign; inability to speak or cry; poor of no air exchange; weak, ineffective cough poor no cough at all; high pitched noise while inhaling or no noise at all; increased respiratory difficulty; and possible cyanosis (turning blue)
which rescuer is performing chest compressions correctly on and infant during 2 rescuer CPR? A. 2 fingers on chest technique B. 2 thumb-encircling hands technique.
B. during 2 rescuer CPR, the rescuer doing compressions should use the 2 thumb-encircling hands technique.
a rescuer has determined that the victim, suspected of having an opioid associated life threatening emergency is unresponsive, is not breathing normally, and has no pulse. which action should the rescuer do next? A. administer naloxone per local protocols and monitor the response. B. provide high quality CPR and use the AED as as it is available.
B. for a suspected opioid associated life threatening emergency in a victim who is unresponsive, is not breathing normally, and has no pulse, the rescuer should provide high quality CPR and use the AED as soon as it is available. then if local protocol allows, the rescuer may give naloxone after starting CPR.

in an infant who is choking, chest thrusts are delivered in the middle of the chest, over the upper half of the breastbone. T or F
F. while keeping the infants head lower than the chest, the rescuer should deliver up to 5 quick, downward chest thrusts in the same location as for chest compressions, just below the nipple line, over the lower half of the breastbone. for choking relief in an infant, the sequence of up to 5 back slaps and up to 5 chest thrusts is repeated until the object is removed or the infant becomes unresponsive.
before attaching the AED pad to a victim with a medication patch on his chest, the rescuer should quickly remove the patch and wipe the area clean first. T or F
T. Do not place the AED pads directly on top of a medication patch, because it may block the transfer of energy from the AED pad to the heart and also cause small burns to the skin. if you notice that the victim has a medication patch on the AED placement area, quickly remove the patch and wipe the area clean before attaching the AED pad. examples of medication patches are nitroglycerine, nicotine, pain medications and hormone replacement therapy patches.
adult AED pads deliver a higher shock dose, but a higher shock dose is preferred to no shock for infants and children less than 8 years of age. T or F
T. although adult pads deliver a higher shock dose, a higher shock dose rather than no shock is preferred for infants and children less than 8 years of age.
a rescuer should give breaths at the rate of 1 breath every 6 seconds during 2 rescuer CPR for an adult when an advanced airway is in place. T or F
T. during 2 rescuer CPR for an adult when an advanced airway is in place, the rescuer does not stop compressions to give breaths. the rescuer gives 1 breath every 6 seconds, which results in 10 breaths per minute.
when they are available, the rescuer should use child pads with a pediatric dose attenuator for infants and children less than 8 years of age. T or F
T. for infants and children less than 8 years of age., the rescuer should use child pads with pediatric dose attenuator with and AED when they are available.
rescue breathing is providing breaths to a victim who has a pulse but is not breathing. T or F
T. if a victim, has a pulse but isn't breathing, rescuers should deliver breaths without chest compressions. this is known as rescue breathing.
when giving CPR to an infant who is choking and becomes unresponsive, the rescuer should look for the object in the back of throat each time the airway is opened. T or F
T. if the choking infant becomes unresponsive, the rescuer should immediately begin CPR, starting with chest compressions. each time the airway is opened, the rescuer should look for the object in the back of the throat. if the object is seen and can easily be removed, the rescuer should remove it.
if a rescuer is alone and did not see the child collapse, the rescuer should perform 2 minutes of CPR before leaving the child to activate the EMS and get the AED. T or F
T. if the rescuer is alone and did not see the child collapse, the rescuer should perform 2 minutes of CPR before leaving the child to activate the emergency response system and get the AED.
