Question 5

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. Increased blood flow to her heart caused her ventricles to stop fibrillating, which restored her pulse.
B. Pressure was relieved from her aorta and vena cava, which improved chest compression effectiveness.
C. Displacement of her uterus allowed her lungs to expand more fully, which restored her pulse.
D. Displacement of her uterus caused blood to flow backward, which increased blood flow to her heart.

Answer 5

B. Pressure was relieved from her aorta and vena cava, which improved chest compression effectiveness.

Question 6

CPR retraining is the MOST effective when it:

Select one:
A. is delivered by computer.

C. a valid living will is unavailable.

CPR will NOT be effective if the patient is:

Select one:
A. horizontal.
B. supine.
C. prone.
D. on a firm surface.

Answer 8

C. prone.

Question 9

Gastric distention will MOST likely occur:

Select one:

a. when the airway is completely obstructed.
b. if you ventilate a patient too quickly.
c.
d. in patients who are intubated.
e. when you deliver minimal tidal volume.

Answer 9

b. if you ventilate a patient too quickly.

Question 10

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

Answer 10

C. remove it

Question 11

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

Select one:
A. respiratory arrest.
B. a cardiac dysrhythmia.
C. a drug overdose.
D. severe chest trauma.

Answer 11

A. respiratory arrest.

Question 12

Several attempts to adequately open a trauma patient’s airway with the jaw-thrust maneuver have been unsuccessful. You should:

Select one:
A. suction the airway and reattempt the jaw-thrust maneuver.
B. try opening the airway by lifting up on the chin.
C. carefully perform the head tilt-chin lift maneuver.
D. tilt the head back while lifting up on the patient’s neck.

Answer 12

C. carefully perform the head tilt-chin lift maneuver.

Question 13

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

Select one:
A. acute cyanosis.
B. forceful coughing.
C. inability to speak.
D. grasping the throat.

Answer 13

B. forceful coughing.

Question 14

The impedance threshold device (ITD) may improve circulation during active compression-decompression CPR by:

Select one:
A. maintaining increased intrathoracic pressure during the downward stroke of each chest compression, which forces more blood from both of the ventricles.
B. 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.
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.

Answer 14

B. 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.

Question 15

What is the correct compression-to-ventilation ratio for adult CPR?

Select one:
A. 30:1
B. 5:1
C. 3:2
D. 30:2

Answer 15

D. 30:2

Question 16

Answer 16

C. with one or two hands.

Question 17
