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. |- |ANSWER-D. |Pressure |was |relieved |from |her |aorta |and |vena |cava, |which |improved |
chest |compression |effectiveness.

B. |is |delivered |by |computer.

C. |involves |hands-on |practice.

D. |is |self-paced |and |brief. |- |ANSWER-C. |involves |hands-on |practice.



CPR |should |be |initiated |when:

Select |one:

,C. |the |carotid |pulse |is |very |weak.

D. |a |valid |living |will |is |unavailable. |- |ANSWER-D. |a |valid |living |will |is |unavailable.

Select |one:

A. |supine.

B. |prone.

C. |horizontal.

D. |on |a |firm |surface. |- |ANSWER-B. |prone.

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. |- |ANSWER-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 |- |ANSWER-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. |- |ANSWER-C. |respiratory |arrest.



Several |attempts |to |adequately |open |a |trauma |patient's |airway |with |the |jaw-thrust |maneuver |have |

Select |one:

A. |try |opening |the |airway |by |lifting |up |on |the |chin.

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.

|forces |more |blood |from |the |ventricle |during |each |compression. |- |ANSWER-A. |limiting |the |amount |of |

air |that |enters |the |lungs |during |the |recoil |phase |between |chest |compressions, |which |results |in |
