ADVANCED LIFE SUPPORT ALS EXAM
UPDATED QUESTIONS WITH 100% SOLVED
ANSWERS!!
What is the most effective way to provide ventilation through a bag - mask device?
Two-hand mask hold with two providers
Attaching a reservoir and oxygen flow of 8 litres/min you can deliver approximately
85% oxygen concentration
Does properly performed bag-mask ventilation provide adequate ventilation and
oxygenation to a patient requiring airway support?
Yes
Where does the patient´s expired air go during bag-mask-ventilation when there is
spontaneous breathing?
Patient´s expired air is diverted to the atmosphere via a one-way valve
When drugs are administered peripherally how much should you flush?
20 mL
For a successful delivery through a peripheral vein how long should you eleavate the
extremity?
10-20 seconds
What should you do if intravenous access can't be established within 2 minutes of
resuscitation?
,Intraosseous (IO) access should be gained.
Is it safe to use intraosseous (IO) access for any IV drug or resuscitation fluid?
Yes
How do you administer crystalloid fluid via IO?
Under pressure using an infusion pump, pressure bag, or manual injection through a syringe and
stopcock.
Where are common places to insert IO access?
Proximal tibia, proximal humerus, distal tibia
Where should you place ECG electrodes?
Over bony prominences
What lead displays the best ECG trace for monitoring?
Lead II
Why is lead II the best for ECG monitoring?
Most of the heart's electrical current flows toward its positive axis. This lead gives the best view
of the ECG waves and best shows the heart's conduction system's activity.
What is the best technique for detecting evidence of myocardial ischaemia?
12-lead ECG monitoring
What does a completely straight ECG line demonstrate?
Indicates usually that a monitor lead has become disconnected
, What should you do if you cannot see any electrical activity (fine line)?
Check that the gain control is not too low and that the electrodes and leads are connected to both
the patient and the monitor.
What rate should chest compressions be given at?
30:2. Chest compressions should be given at 120 a minute
What rate should ventilations be given at?
8 per min. Once a supraglottic airway device has been inserted, ventilation at a rate of 10
breaths/min
How often should interruptions in CPR occur?
No more frequently than every 2 minutes, and for the shortest possible duration.
How often should pulse / rhythm check be done?
Every cycle
What causes a greater chance of successful defibrillation and survival?
The shorter the interval between the onset of VF/VT and delivery of the shock
What influences defibrillation success?
Depends on sufficient current being delivered to the myocardium, which is influenced by
transthoracic impedance and electrode position.
What is transtoracic impedance
Electrical resistance
