Science Of Resuscitation and Systematic Approach

What is the purpose of a medical emergency team (MET) or rapid response team (RRT)?

• Providing online consultation to EMS personnel in the field

• Improving care for deteriorating patients admitted to critical care units

• Improving patient outcomes by identifying and treating early clinical deterioration

• Providing diagnostic consultation to emergency department patients

What is an effect of excessive ventilation?

• Decreased cardiac output

• Decreased intrathoracic pressure

• Increased perfusion pressure

• Increased venous return

ROSC is unlikely if PETCo2 reading is less than 10 mm Hg

• True

• False

What is the the first link in the Chain of survival for In-hospital Cardiac Arrest?

• Rapid Defibrillation

• Surveillance, prevention, and treatment of prearrest conditions

• Immediate recognition of cardiac arrest and activation of the Code Blue

• Early CPR with emphasis on chest compressions

Which best describes the length of time it should take to perform a pulse check during BLS assessment?

• 1 to 4 seconds

• 5 to 10 seconds

• 11 to 15 seconds

• 16 to 20 seconds

Rapid defibrillation is a link in the Adult Chain of Survival. Why is this important to survival?

• It prevents cardiac arrest

• It prevents respiratory arrest

• It provides normal respiration

• It eliminates the abnormal heart rhythm

What is the minimum systolic blood pressure one should attempt to achieve with fluid administration or vasoactive agents in a hypotensive post-cardiac arrest patient who acheives ROSC?

• 75 mm Hg

• 80 mm Hg

• 85 mm Hg

• 90 mm Hg

Two rescuers are performing CPR. To maintain the quality of chest compression, they should ?

• Interrupt CPR and change positions after resting a couple of minutes.

• Immediately stop chest compressions . Give about 10 to 12 rescue breath per minute.

• Slow down and interrupt compressions more frequently to check the pulse.

• Quickly change positions every after 2 minutes or if fatigue.

What is the survival advantages does CPR provide to a patient in cardiac arrest?

• Increases defibrillation threshold

• Directly restores an organized rhythm

• Opposes the harmful effects of epinephrine

• Produces a small amount of blood flow to the heart

What is the rate for performing chest compression for victim of all ages?

• At least 80 compression per minute

• At a rate of 100 to 120 compression per minute

• At least 30 compression per minute

• At a rate of 15 to 30 compression per minute
