Take the free BLS Pretest provided below in order to prepare you for our official BLS online exam. The practice exam consists of 10 multiple-choice questions that are derived from the BLS provider handbook and adhere to the latest AHA and ECC guidelines.\u00a0Correct answers & explanations will be shown once the practice test is submitted.=======================================<\/p>\n
Assess the victim, give 2 rescue breaths, defibrillate, start CPR<\/p>\n
Check pulse, give rescue breaths, assess the victim, defibrillate<\/p>\n
Assess the victim, activate EMS and get AED, check pulse, start CPR<\/p>\n
Assess the victim, start CPR, give 2 rescue breaths, defibrillate<\/p>\n
Answer Explanation==============================<\/p>\n
The 2010 AHA guidelines recommend starting CPR before initiating rescue breathing.<\/p>\n
Assessing the victim, activating EMS, rapid use of an AED, checking pulse, and beginning CPR is the correct sequence of events for BLS.<\/p>\n
The 2010 AHA guidelines recommend initiating CPR prior to giving rescue breaths, and this sequence does not activate EMS.<\/p>\n
This sequence fails to activate EMS.<\/p>\n
<\/p>\n
=============================================<\/p>\n
Airway, Breathing, Check Pulse<\/p>\n
None of the above<\/p>\n
Airway, Breathing, Chest Compressions<\/p>\n
Chest compressions, Airway, Breathing=======================================================================================<\/p>\n
Answer Explanation<\/p>\n
The 2010 guidelines recommend beginning with chest compressions to perfuse the brain, heart and other organs as soon as possible.<\/p>\n
The AHA no longer recommends beginning with \u201cAirway\u201d as it delays initiation of chest compressions.<\/p>\n
The AHA changed from \u201cA, B, C\u201d to \u201cC, A, B\u201d in 2010 to emphasize the importance of early chest compressions in successful resuscitation.<\/p>\n
None of the above is incorrect.======================================================================================<\/p>\n
Every 2 to 3 seconds ( 20 to 30 breaths per minute)<\/p>\n
Every 10 to 12 seconds ( 5 to 6 breaths per minute)<\/p>\n
Every 4 to 5 seconds ( 12 to 15 breaths per minute)<\/p>\n
Every 6 to 8 seconds ( 8 to 10 breaths per minute)<\/p>\n
Answer Explanation=================================<\/p>\n
Twenty to thirty breaths per minute will result in hyperventilation which impedes the return of spontaneous circulation.<\/p>\n
One breath every 4 to 5 seconds will result in hyperventilation and is faster than the AHA guidelines recommend.<\/p>\n
One breath every 6 to 8 seconds results in 8 to 10 breaths per minute and is the correct ventilation rate for an adult victim with an advanced airway.<\/p>\n
One breath every 10 to 12 seconds is slower than AHA guidelines recommend.====================================================================================<\/p>\n
Poor air exchange<\/p>\n
Inability to speak<\/p>\n
High-pitched noise while inhaling<\/p>\n
All of the above=========================================================================================<\/p>\n
Answer Explanation<\/p>\n
Poor airway exchange results in impaired ventilation and may be a sign of airway obstruction.<\/p>\n
High pitched noise while inhaling, called stridor, is a sign of upper airway impairment and may represent a partial airway obstruction.<\/p>\n
Speech requires movement of air across the vocal cords. An airway obstruction will prevent this air movement and therefore speech.<\/p>\n
All of the above represent signs of possible airway obstruction.====================================================================================<\/p>\n
Attach electrode pads, check pulse, shock patient, analyze rhythm<\/p>\n
Check pulse, attach electrode pads, analyze rhythm, shock patient<\/p>\n
Power on the AED, attach electrodes pads, analyze the rhythm, clear the patient, deliver shock<\/p>\n
Power on the AED, attach electrode pads, shock the patient, analyze the rhythm========================================================================================<\/p>\n
Answer Explanation<\/p>\n
The patient must be analyzed before the AED will advise a shock<\/p>\n
This represents the correct steps for operating an AED.<\/p>\n
The rhythm must be analyzed before the AED will advise a shock. A pulse check should have been done prior to attaching the AED and is not part of AED operation.<\/p>\n
This sequence does not begin with powering on the AED.=========================================================================================<\/p>\n
Advanced airway placement<\/p>\n
Early CPR<\/p>\n
Integrated Post-Cardiac Arrest Care<\/p>\n
Rapid Defibrillation<\/p>\n
Answer Explanation<\/p>\n
Early CPR provides vital oxygen to the brain and vital organs increasing the likelihood of recovery.<\/p>\n
Rapid defibrillation increases the chance of effectively restoring a normal heart rhythm.<\/p>\n
Advanced airway placement is not part of the BLS adult chain of survival.<\/p>\n
Post cardiac arrest care reduces the possibility of long-term impairment and increases the chance of a victim making a full recovery.<\/p>\n
============================================<\/p>\n
After every 10 cycles of CPR<\/p>\n
After every cycle of CPR<\/p>\n
After every 2 cycles of CPR<\/p>\n
Answer Explanation<\/p>\n
Changing roles after every cycle of CPR will create too many interruptions and impair successful resuscitation.<\/p>\n
Changing roles after every 2 cycles of CPR will create frequent interruptions in perfusion and is not consistent with AHA recommendations.<\/p>\n
Changing roles after every 5 cycles of CPR is the currently recommended frequency to promote high-quality CPR.<\/p>\n
CPR is physically demanding and waiting to switch roles every 10 cycles will likely fatigue the rescuer performing chest compressions resulting in lower quality CPR.==================================================================================<\/p>\n
15:2<\/p>\n
10:1<\/p>\n
30:1<\/li>\n
Answer Explanation<\/p>\n
10:1 is not a correct compression to ventilation ratio and will result in inadequate perfusion.<\/p>\n
30:1 is not a correct ratio and will result in inadequate ventilation.<\/p>\n
30:2 is the AHA expert consensus for the correct ratio of compressions to ventilation.<\/p>\n
15:2 is not the correct ratio for compressions to ventilation in single rescuer CPR.==================================================================================<\/p>\n
<\/p>\n
Where should you attempt to perform a pulse check on a child from 1 year of age to puberty<\/li>\n
Ulnar artery<\/p>\n
Brachial artery<\/p>\n
Temporal artery<\/p>\n
Carotid or Femoral artery<\/p>\n
Answer Explanation<\/p>\n
The brachial artery located on the upper arm is used in infants below 1-year-old.<\/p>\n
The ulnar artery is not used to perform pulse checks in BLS.========================================<\/li>\n
The carotid and femoral arteries are used to perform pulse checks in BLS on children from 1 year of age to puberty.<\/p>\n
Push hard and fast<\/p>\n
Minimize interruptions<\/p>\n
Starting chest compressions within 10 seconds of recognition of cardiac arrest<\/p>\n
All of the above<\/p>\n
Answer Explanation<\/p>\n
Minimizing interruption of circulation by quickly recognizing cardiac arrest and beginning CPR is an important characteristic of high-quality CPR and is emphasized by the AHA guidelines.<\/p>\n
Pushing hard enough to compress the heart and squeeze blood out, and fast enough to raise blood pressure is a vital characteristic of high-quality CPR and is emphasized in the 2010 AHA guidelines.<\/p>\n
Minimizing interruptions in CPR keeps blood pressure high enough to perfuse vital organs including the heart and brain and is critical to improving outcomes in cardiac arrest.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
