Advanced Life Support Exam Questions With Accurate
Answers.
What is the most effective way to provide ventilation through a bag - mask
device? - accurate answers-Two-hand mask hold with two providers
Attaching a reservoir and oxygen flow of 8 litres/min you can deliver
approximately - accurate answers-85% oxygen concentration
Does properly performed bag-mask ventilation provide adequate ventilation
and oxygenation to a patient requiring airway support? - accurate answers-
Yes
Where does the patient´s expired air go during bag-mask-ventilation when
there is spontaneous breathing? - accurate answers-Patient´s expired air is
diverted to the atmosphere via a one-way valve
When drugs are administered peripherally how much should you flush? -
accurate answers-20 mL
For a successful delivery through a peripheral vein how long should you
elevate the extremity? - accurate answers-10-20 seconds
What should you do if intravenous access can't be established within 2
minutes of resuscitation? - accurate answers-Intraosseous (IO) access should
be gained.
Is it safe to use intraosseous (IO) access for any IV drug or resuscitation fluid?
- accurate answers-Yes
How do you administer crystalloid fluid via IO? - accurate answers-Under
pressure using an infusion pump, pressure bag, or manual injection through a
syringe and stopcock.
Where are common places to insert IO access? - accurate answers-Proximal
tibia, proximal humerus, distal tibia
Where should you place ECG electrodes? - accurate answers-Over bony
prominences
, What lead displays the best ECG trace for monitoring? - accurate answers-
Lead II
Why is lead II the best for ECG monitoring? - accurate answers-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? -
accurate answers-12-lead ECG monitoring
What does a completely straight ECG line demonstrate? - accurate answers-
Indicates usually that a monitor lead has become disconnected
What should you do if you cannot see any electrical activity (fine line)? -
accurate answers-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? - accurate answers-30:2.
Chest compressions should be given at 120 a minute
What rate should ventilations be given at? - accurate answers-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? - accurate answers-No more
frequently than every 2 minutes, and for the shortest possible duration.
How often should pulse / rhythm check be done? - accurate answers-Every
cycle
What causes a greater chance of successful defibrillation and survival? -
accurate answers-The shorter the interval between the onset of VF/VT and
delivery of the shock
What influences defibrillation success? - accurate answers-Depends on
sufficient current being delivered to the myocardium, which is influenced by
transthoracic impedance and electrode position.
