BASIC LIFE SUPPORT (BLS) TRAININGACCURATE QUESTIONS AND ANSWERS
WITH SOLUTIONS 2024
What percent of adult patients with non traumatic cardiac arrest who are treated by EMS survive to
hospital discharge? - ANSWER 10%
For the purposes of the BLS course, age definitions are as follows: - ANSWER Adult: after onset of
puberty and older
Children: 1 year to puberty
Infant: <1 year of age
What are the components of CPR? - ANSWER Airway check, chest compressions, and breaths
What are the steps for high quality CPR? - ANSWER 1. Start compressions wishing 10 seconds of
recognition of cardiac arrest
2. Push hard and fast (rate of 100-120/min)
3. Allow complete chest recoil after each compression
4. Minimize interruptions in compressions (less than 10 seconds)
5. Give effective breaths that make the chest rise
6. Avoid excessive ventilation
How deep should you compress for each age group? - ANSWER Adults: at least 2 inches
Children: at least 1/3 of the depth of the chest; about 2 inches
Infants: at least 1/3 of the depth of the chest; about 1.5 inches
What is a cath lab? - ANSWER A cardiac catheterization lab is a group of procedure rooms in a
hospital/clinic where specialized equipment is used to evaluate the heart and the blood vessels around
the heart and in the lungs
What does a cardiac catheterization procedure entail? - ANSWER It involves the insertion of a catheter
through an artery or vein into the heart to study the heart and its surrounding structures and function.
, Measurements and contrast material can help diagnose problems or the catheter can be used to fix
some problem (like a blocked artery)
How would you recognize that someone has had cardiac arrest? - ANSWER The victim will be
unresponsive, not breathing or only gasping, and no pulse
How does rapid defibrillation work and what effect does it have on a patient undergoing cardiac arrest? -
ANSWER Rapid defibrillation can identify lethal heart rhythms and deliver a shock to terminate the
abnormal rhythm and allow the heart's normal rhythm to resume. In conjunction with high-quality CPR,
rapid defibrillation can double or triple the chances of survival
In adults, cardiac arrest is often sudden and results from a cardiac cause. How does cardiac arrest usually
present in children? - ANSWER In children, cardiac arrest is often secondary to respiratory failure and
shock. Identifying children with these problems is essential to reduce the likelihood of pediatric cardiac
arrest and maximize survival and recovery. Therefore, a prevention link is added in the pediatric Chain of
Survival.
What is the difference between cardiac arrest and a heart attack? - ANSWER Sudden cardiac arrest
occurs when the heart develops an abnormal rhythm and can't pump blood. A heart attack occurs when
blood flow to part of the heart muscle is blocked
When does cardiac arrest occur (what happens with the cardiology)? - ANSWER Sudden cardiac arrest
results from an abnormal heart rhythm. This abnormal rhythm causes the heart to quiver so it can no
longer pump blood to the brain, lungs, and other organs. Sudden cardiac arrest is often a "rhythm"
problem.
When does a heart attack occur (what happens with the cardiology)? - ANSWER A heart attack occurs
when a clot forms in a blood vessel carrying oxygenated blood to the heart muscle. If the blocked vessel
is not reopened quickly, the muscle normally nourished by that vessel begins to die. A heart attack is a
"clot" problem.
What happens after sudden cardiac arrest? - ANSWER Within seconds, the person becomes
unresponsive and is not breathing or is only gasping. Death occurs within minutes if the victim does not
receive immediate lifesaving treatment.
