1338 (Chapter 15) Quiz 6

During two-rescuer CPR, the compressor and ventilator switch positions. While rescuer one is finishing his or her cycle of 30 compressions, rescuer two should:

move to the opposite side of the patient's chest.

Basic life support (BLS) is defined as:

noninvasive emergency care that is used to treat conditions such as airway obstruction, respiratory arrest, and cardiac arrest.

Abdominal thrusts in a responsive child or adult with a severe upper airway obstruction are performed:

until he or she becomes unresponsive.

When ventilating an apneic adult with a simple barrier device, you should deliver each breath:

while watching for adequate chest rise.

You and your partner arrive at the side of a 60-year-old woman who suddenly collapsed about 7 minutes ago. She is unresponsive, apneic, and pulseless. You should:

begin CPR and apply the AED as soon as possible.

When assessing the pulse of an unresponsive infant, you should palpate the ________ artery.

brachial

The fourth link in the chain of survival includes:

basic and advanced EMS care.

In which of the following situations can aortocaval compression reduce the chance of successful resuscitation from cardiac arrest?

Advanced pregnancy

What is the correct ratio of compressions to ventilations when performing two-rescuer child CPR?

15:2

In two-rescuer adult CPR, you should deliver a compression-to-ventilation ratio of:

30:2

During cardiac arrest, the resuscitation team should maintain a chest compression fraction of at least:

60%.

Complications that may be associated with chest compressions include all of the following, except:

gastric distention.

During one-rescuer adult CPR, you should compress the patient's chest at a rate of at least ________ compressions per minute.

100

A man is unresponsive after overdosing on heroin. He is apneic and his pulse is slow. Which of the following is the most critical intervention?

Bag-mask ventilation

Which of the following is not a BLS intervention?

Cardiac monitoring

Which of the following techniques should you use to dislodge a foreign body airway obstruction in a patient who is in an advanced stage of pregnancy or who is very obese?

Chest thrusts

Which of the following is considered an obvious sign of death and would not require the initiation of CPR?

Dependent blood pooling

Which of the following maneuvers should be used to open a patient's airway when a spinal injury is suspected?

Jaw-thrust

Ventricular tachycardia is:

a rapid contraction of the ventricles that does not allow for normal filling of the heart.

Appropriate treatment for a patient with a mild upper airway obstruction includes:

administering oxygen and transporting immediately.

If ventilation becomes difficult due to gastric distention, the patient will require:

an orogastric or nasogastric tube.

Initial treatment to dislodge a severe foreign body airway obstruction in a responsive infant involves

back blows.

After an advanced airway device has been inserted during cardiac arrest, you should ventilate an infant or child:

by giving one breath every 6 seconds

After establishing that an adult patient is unresponsive and not breathing, you should:

check for a carotid pulse.

You should deliver chest compressions to an adult patient in cardiac arrest by:

compressing over the lower half of the sternum.

After an advanced airway has been inserted during two-rescuer CPR, you should:

deliver ventilations at a rate of 10 breaths per minute.

Signs of a sudden severe upper airway obstruction include all of the following, except:

forceful coughing.

A 55-year-old man is found unresponsive in his bed. He is pulseless and apneic. You should:

move the patient to the floor.

A patient should be placed in the recovery position when he or she:

is unconscious, uninjured, and breathing adequately

A 29-year-old woman, who is 35 weeks pregnant, is in cardiac arrest. You should

manually displace her uterus to the left.

In most cases, cardiopulmonary arrest in infants and children is caused by:

respiratory arrest.

The main benefit of using a mechanical piston or load-distributing band device for chest compressions is:

the elimination of rescuer fatigue that results from manual compressions.
