The primary waste product of aerobic metabolism is:
,A. carbon dioxide.
B. lactic acid.
C. pyruvic acid.
D. adenosine triphosphate ---------CORRECT ANSWER-----------------A.
carbon dioxide.
The process of exchanging oxygen and carbon dioxide between the alveoli
and the blood of the capillaries is called:
A. pulmonary ventilation.
B. alveolar ventilation.
C. external respiration.
D. cellular metabolism. ---------CORRECT ANSWER-----------------C.
external respiration
To select the proper size oropharyngeal airway, you should measure from
the:
A. corner of the mouth to the superior ear.
B. center of the mouth to the posterior ear.
C. angle of the jaw to the center of the mouth.
D. corner of the mouth to the earlobe. ---------CORRECT ANSWER-----------
------D. corner of the mouth to the earlobe.
Which of the following factors will cause a decreased minute volume in an
adult?
A. Increased tidal volume
B. Slight decrease in respiratory rate
C. Respirations of 20 breaths/min
D. Shallow breathing ---------CORRECT ANSWER-----------------D. Shallow
breathing
,Several attempts to adequately open a trauma patient's airway with the
jaw-thrust maneuver have been unsuccessful. You should:
A. tilt the head back while lifting up on the patient's neck.
B. carefully perform the head tilt-chin lift maneuver.
C. suction the airway and reattempt the jaw-thrust maneuver.
D. try opening the airway by lifting up on the chin. ---------CORRECT
ANSWER-----------------B. carefully perform the head tilt-chin lift maneuver.
Signs of a sudden severe upper airway obstruction include all of the
following, EXCEPT:
A. forceful coughing.
B. grasping the throat.
C. acute cyanosis.
D. inability to speak. ---------CORRECT ANSWER-----------------A. forceful
coughing.
The impedance threshold device (ITD) may improve circulation during
active compression-decompression CPR by:
A. 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.
B. 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.
C. maintaining increased intrathoracic pressure during the downward
stroke of each chest compression, which forces more blood from both of
the ventricles.
D. 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. ---------CORRECT ANSWER-----------
------D. 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?
A. 30:2
B. 30:1
C. 3:2
D. 5:1 ---------CORRECT ANSWER-----------------A. 30:2
When performing CPR on a child, you should compress the chest:
A. until a radial pulse is felt.
B. to a depth of 1 to 2 inches.
C. 80 to 100 times per minute.
D. with one or two hands. ---------CORRECT ANSWER-----------------D. with
one or two hands
While rescuer one is finishing his or her fifth cycle of 30 compressions,
rescuer two should:
A. assess for a carotid pulse for 15 seconds.
B. give two breaths and prepare to start compressions.
C. move to the opposite side of the patient's chest.
D. suction the patient's mouth and give two more ventilations. ---------
CORRECT ANSWER-----------------C. move to the opposite side of the
patient's chest.
Without practice, your CPR skills will __________.
Select one:
A. improve over time
B. deteriorate over time
