BLS Study Questions

T. the rescuer should deliver up to 5 back slaps forcefully between the infants shoulder blades, using the heel of the hand, delivering each slap with enough force to attempt to remove the obstruction. for chocking 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.

B. when the victim as an adult, check the carotid pulse

B. rescuers should perform chest compressions at the rate of 100 to 120 per minute.

T. to use a pocket mask, the rescuer positions himself at the victims side.

T. when placing the pocket mast on the victims face, the rescuer uses the bridge of the nose as a guide to correct position.

T. each breath should be delivered over 1 second, enough to make the victims chest rise.

c. the AED operator clears the victim before rhythm analysis and then clears the victim before delivering a shock.

a. after the AED gives the shock, rescuers should resume CPR immediately, beginning with chest compressions.

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.

F. if a rescuer places an AED pad directly over an implanted medical device, the implanted device may block delivery of the shock to the heart. if possible, the rescuer should avoid placing the AED pad directly over the implanted device.

T. water is a good conductor or electricity. if the chest is covered with some water, quickly wipe the chest before attaching the AED pads.

F. if the victim has a hairy chest, the AED pads may stick to the hair and not to the skin on the chest. the rescuer should shave the area where he will place the pads by using the razor from, the AED carrying case. if you have a second set of AED pads, you can use the first set to remove the hair. apply the pads, press them down so they stick as much as possible, and quickly pull them off. then apply the new second set of pads.

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.

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.

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.

F. when compressing an infants chest, a single rescuer should use 2 fingers in the center of the infants chest, just Below the nipple line, on the Lower half of the breastbone.

T. when performing chest compressions on an infant, the rescuer pushes hard and fast at a depth of at least one third the anteroposterior diameter of the chest, or about 1.5 inches.

B. during 2 rescuer CPR, the rescuer doing compressions should use the 2 thumb-encircling hands technique.

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.

F. Adult AED pads may be used on an infant if pediatric pads with a dose attenuator or manual defibrillator is not available.

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.

F. it is important to place the AED pads so that they do not touch or overlap each other

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.

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.

T. if a victim, has a pulse but isn't breathing, rescuers should deliver breaths without chest compressions. this is known as rescue breathing.

F. for rescue breathing given to infants and children, give 1 breath every 3-5 seconds, or about 12 to 20 breaths per minute.

F. the compression rate when advanced airway is in place should remain at 100 to 120/min, with no pause to deliver breaths.

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.

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.

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.

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)

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.

T. the rescuer should deliver up to 5 back slaps forcefully between the infants shoulder blades, using the heel of the hand, delivering each slap with enough force to attempt to remove the obstruction. 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.

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.

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.
