C)grasping the throat.
CORRECT D)forceful coughing.
Which of the following is considered an obvious sign of death and would not require the initiation of CPR?
dependent blood pooling
A patient should be placed in the recovery position when he or she:
is unconscious, uninjured, and breathing adequately.
What is the correct ratio of compressions to ventilations when performing two-rescuer child CPR?
You should deliver chest compressions to an unconscious adult patient in cardiac arrest by:
compressing the sternum between the nipples.
A 60-year-old male is found to be unresponsive, pulseless, and apneic. You should:
begin CPR until an AED is available.
Which of the following maneuvers should be used to open a patient's airway when a spinal injury is suspected?
Complications associated with chest compressions include all of the following, EXCEPT:
CORRECT C)gastric distention.
D)a fractured sternum.
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.
You have assessed an unresponsive middle-aged female and determined that she is in cardiac arrest. When you apply the AED pads, you note that she has a medication patch over the same area where one of the AED pads will be placed. You should:
remove the medication patch, wipe away any medication residue, and apply the AED pads.

Which of the following is NOT an indication to stop CPR once you have started?
Care is transferred to a bystander.
If gastric distention is interfering with your ability to adequately ventilate a patient, you may have to:
apply manual pressure to the abdomen
Your initial attempt to ventilate an unresponsive apneic 30-year-old man is met with resistance and you do not see the chest rise. Your second ventilation attempt is also unsuccessful. You should:
perform 30 chest compressions.
When assessing the pulse of an unresponsive infant, you should palpate the ________ artery.
The MOST appropriate treatment for a patient with a mild upper airway obstruction includes:
administering oxygen and transporting immediately.
Which of the following statements regarding ventricular fibrillation (V-fib) is MOST correct?
A)It is an uncommon dysrhythmia in patients with sudden cardiac arrest.
B)AEDs should not be used to defibrillate patients in V-fib.
C)The only indication for immediate defibrillation is V-fib.
CORRECT D)Survival rates decrease by 7% to 10% for each minute that V-fib persists.
Which of the following statements regarding the use of the AED in children is MOST correct?
A)AEDs should never be used on children younger than 8 years or less than 55 pounds.
B)AEDs are only effective in pediatric patients if severe trauma is the cause of their cardiac arrest.
CORRECT C)AED use in children between 1 and 8 years of age involves pediatric pads and an energy reducer.
D)AEDs are not used in pediatric patients because they do not experience ventricular fibrillation.
