Chapter 14- Elements of BLS

Question 1

A non-invasive emergency life-saving care that is used to treat medical conditions

Answer 1

Basic life support BLS

Question 2

BLS primarily focuses on

Answer 2

Airway obstruction, respiratory arrest, and cardiac arrest

Question 3

BLS follows a specific sequence for adults and for infants and children. This care focuses on the ABCs in the following order:

Answer 3

airway (obstruction)
breathing (respiratory arrest)
circulation (cardiac arrest or severe bleeding)

Question 4

If the patient is in cardiac arrest, then the sequence switches to

Answer 4

CAB
compressions, airway, breathing

Question 5

The cab sequence is used because

Answer 5

In this case, chest compressions are essential and must be started as quickly as possible

Question 6

remember, brain cells die every second they are deprived of oxygen. Permanent brain damage is possible after only ____ to ____ minutes without oxygen

Answer 6

4 to 6 minutes without oxygen

Question 7

actor 0 to 1 minute

Answer 7

Cardiac irritability occurs

Question 8

after 0 to 4 minutes

Answer 8

Brain damage, not likely

Question 9

After 4 to 6 minutes

Answer 9

Brain damage likely possible

Question 10

after 6 to 10 minutes

Answer 10

Brain damage very likely

Question 11

More than 10 minutes

Answer 11

Irreversible brain damage

Question 12

check the patient for ______ and _____ at the same time

Answer 12

Absent or abnormal breathing, and unresponsiveness

Question 13

Check for a pulse for no more than

Answer 13

10 seconds

Question 14

if no pulse is noted, assume that

Answer 14

The patient is in cardiac arrest

Question 15

if the patient has no post, you must combine

Answer 15

Artificial ventilation with artificial circulation, a.k.a. chest compressions

Question 16

If breathing stops before the heart stops then

Answer 16

The patient may still have enough oxygen in the lungs to stay alive for several minutes

Question 17

but when cardiac arrest occurs first

Answer 17

The heart and brain stop receiving oxygen immediately

Question 18

this is used to reestablish circulation and artificial ventilation in a patient who is not breathing and has no pulse

Answer 18

Cardio pulmonary resuscitation CPR

Question 19

Restore circulation using ____ chest compressions at a depth of ____ inches (__ cm)

Answer 19

30 chest compressions
2inches (5 cm)

Question 20

during CPR, the rate should be at least ____ compressions per minute, but no more than ____ compressions per minute

Answer 20

At least 100 compressions per minute, but no more than 120 compressions per minute

Question 21

then, open the airway with the _____ or _______
to restore breathing by providing rescue breaths

Administer ___ breaths, each over 1 second

Answer 21

jaw thrust or head tilt chin lift Maneuver

2 breaths

Question 22

The goal of CPR is to help restore

Answer 22

Spontaneous breathing and circulation

Question 23

you may also need _______ and _______ to achieve this outcome

Answer 23

Defibrillation and advanced interventions, such as medication therapy

Question 24

Basic life support BLS differs from advanced life support which involves life-saving procedures, such as

Answer 24

Administration of IV fluids, and medication’s the use of advanced airways

Question 25

what are some cases where BLS measures may be all that is needed to restore a patient’s pulse and breathing

Answer 25

choking, near drowning, or lightning injuries

Question 26

However, these patients will still require

Answer 26

Transport to the ED for evaluation

Question 27

for a patient to survive cardiac arrest, what is needed?

Answer 27

Effective CPR at an adequate rate in depth with minimal interruptions until defibrillation can be administered not tired

Question 28

BLS care is extremely critical to patient survival.

Answer 28

True

Question 29

It is important to practice skills regularly so that they don’t deteriorate

Answer 29

True
