-Between each chest compression, you should __________.
Select one:
A. check for a pulse
B. allow full chest recoil
C. administer a breath
D. remove your hands from the chest - -B. allow full chest recoil
-Complications associated with chest compressions include all of
the following, EXCEPT:

-CPR is in progress on a pregnant woman. Shortly after
manually displacing her uterus to the left, return of spontaneous
circulation occurs. Which of the following would MOST likely
explain this?
Select one:
A. Displacement of her uterus caused blood to flow backward,
which increased blood flow to her heart.
B. Increased blood flow to her heart caused her ventricles to stop
fibrillating, which restored her pulse.
C. Displacement of her uterus allowed her lungs to expand more
fully, which restored her pulse.
D. Pressure was relieved from her aorta and vena cava, which
improved chest compression effectiveness. - -D. Pressure was
relieved from her aorta and vena cava, which improved chest
compression effectiveness.
-CPR retraining is the MOST effective when it:
Select one:
A. occurs every 24 months.
B. is delivered by computer.
C. involves hands-on practice.
D. is self-paced and brief. - -C. involves hands-on practice.
-CPR should be initiated when:
Select one:
A. rigor mortis is obvious.
B. signs of putrefaction are present.
C. the carotid pulse is very weak.
D. a valid living will is unavailable. - -D. a valid living will is
unavailable.
-CPR will NOT be effective if the patient is:
Select one:
,A. supine.
B. prone.
C. horizontal.
D. on a firm surface. - -B. prone.
-Gastric distention will MOST likely occur:
Select one:
a. when you deliver minimal tidal volume.
b.
c. in patients who are intubated.
d. when the airway is completely obstructed.
e. if you ventilate a patient too quickly. - -e. if you ventilate a
patient too quickly.
-If an object is visible in the unconscious patient's airway, you
should __________.
Select one:
A. leave it in place
B. continue chest compressions
C. remove it
D. place the patient on his or her side - -C. remove it
-In most cases, cardiopulmonary arrest in infants and children is
caused by:
Select one:
A. a cardiac dysrhythmia.
B. severe chest trauma.
C. respiratory arrest.
D. a drug overdose. - -C. respiratory arrest.
-Several attempts to adequately open a trauma patient's airway
with the jaw-thrust maneuver have been unsuccessful. You
should:
Select one:
A. try opening the airway by lifting up on the chin.
B. suction the airway and reattempt the jaw-thrust maneuver.
C. tilt the head back while lifting up on the patient's neck.
D. carefully perform the head tilt-chin lift maneuver. - -D.
carefully perform the head tilt-chin lift maneuver.
, -Signs of a sudden severe upper airway obstruction include all of
the following, EXCEPT:
Select one:
A. grasping the throat.
B. acute cyanosis.
C. inability to speak.
D. forceful coughing. - -D. forceful coughing.
-The impedance threshold device (ITD) may improve circulation
during active compression-decompression CPR by:
Select one:
A. limiting the amount of air that enters the lungs during the
recoil phase between chest compressions, which results in
negative intrathoracic pressure and improved cardiac filling.
B. maintaining increased intrathoracic pressure during the
downward stroke of each chest compression, which forces more
blood from both of the ventricles.
C. drawing all of the air out of the lungs in between chest
compressions, which causes positive intrathoracic pressure and a
reduction of blood return to the right side of the heart.
D. maximizing the amount of air in the lungs following chest
recoil, which hyperinflates the lungs and forces more blood from
the ventricle during each compression. - -A. limiting the amount
of air that enters the lungs during the recoil phase between chest
compressions, which results in negative intrathoracic pressure
and improved cardiac filling.
-What is the correct compression-to-ventilation ratio for adult
CPR?
Select one:
A. 30:2
B. 5:1
