BLS Exam QuizPlease sign up for the course before taking this quiz.If there are 3 members in a team doing CPR, what can they do ideally1 All can cycle through ventilations 2 alternate for compressions and 1 at ventilations 2 operate the AED and 1 at ventilations All can cycle through compressions. Why is chest recoil important1 Chest recoil helps with oxygenation Heart can get injured if there's no recoil Ribcage gets strengthened with recoil Increased chest pressures impair blood flow returning to the heart When do you check pulse during CPR?1 During compressions At the end of 30 compressions, before giving a breath At the end of 5 cycles of CPR At the end of each breath What can AED shock do?1 Prevents the cardiac arrest Stop the abnormal rhythm Start the regular rhythm Get the pulse back Shocks the patient to calm him Roles in a 2-rescuer BLS in a cardiac arrest1 Both gives breaths. One secures the mask, the other squueezes the bag. One rescuer can give breaths the other, compressions One rescuer goes to get an AED, the other gives breaths continuously One rescuer gives compressions and other waits for AED Which is not a feature of high quality CPR1 A rate of 100-120 compressions/min Minimize interruptions Minimize chest recoil Depth of 1/3rd chest diameter (2inches/5cms) What is the ration of chest compressions to breaths in adults?1 30:2 for single rescuer, 15:2 for 2 rescuer 15 compressions to 1 breath 30 compressions to 2 breaths 30 breaths to 2 compressions 100-120 compressions to 2 breaths in a minute Which of the following can help you suspect Airway obstruction?1 Snoring Stridor Gurgling sounds All of the options Regarding a bag mask device1 Use C-E technique to secure the mask on face All the options are correct Should be used from the head end Ideally used when there are 2 people. What happens when you compress at a faster rate than recommended 100-120 / min?1 Oxygen cannot reach lungs You will get tired faster Heart chambers will not have time to refill You might break the ribcage What happens when you give excess air while ventilating?1 Next breath will be difficult Heart's own blood supply is stopped Blood pressure goes up Venous return to the heart is compromised How to check the response in an adult?1 Call his name in a calm composed manner Firmly tap the shoulders and shout Gently tap on feet Use a flash light Punch the victim till he responds Your AED says shock adviced, what is your next step?1 Announce CLEAR Listen to AED voice STOP CPR Check pulse Press the SHOCK button What to do after delivering a shock?1 Turn off the AED. and do CPR Wait for 2 minutes Remove pads from chest Check pulse for 10seconds Resume CPR for 2 minutes In a 2-rescuer BLS1 Switch roles after 5 minutes Never switch roles Switch roles after 2 minutes Switch roles after 2 cycles Head tilt – Chin lift1 Must be avoided if neck injury is suspected Is an advanced airway manouvre, must be done by advanced heath care providers only Head is tilted to one side, left or right Should be attempted only when there is no pulse. What is step 1 while using AED?1 Call EMS Turn on the AED Apply pads on victim Plug in the connector Remove batteries When performing CPR with an advanced airway,1 Maintain 30:2 compressions to breaths ratio Advanced airway should be attempted only if there's a pulse No need of giving breaths, just continue compressions Compressions are continuous and breaths at every 6 seconds What happens with interruptions in chest compressions?1 Drastic improvement in perfusion Improved output from heart Perfusion pressures go down Rescuers get tired In which of these cases, AED pads can be used normally?1 If the victim is in water If there is a medicine patch If there's an implanted ICD under skin If there is excess hair on chest Unresponsive adult without pulse What is the national emergency number for INDIA?1 911 100 101 108 102 112 What is the first step in BLS?1 Check if you have access to a phone. Check for scene safety Check pulse Check pulse and breathing simultaneously Check breathing For chest compressions to be effective, the surface should be1 Flat and firm Surface with a bump in middle It doesn't matter Soft and fluffly to avoid injuries Regarding depth of chest compressions1 Compress upto 4cm in adults Compress 1/3rd the chest Compress 5cm depth Compress as deep as possible About rescue breaths1 Given 30:2 in someone with a pulse Given every 5-6 seconds in someone without a pulse Given every 5-6 seconds in someone with a pulse Given every 2 seconds in someone with a pulse Back to: BLS Exam
