This is a self-assessment quiz for Lesson 2: The Science of ACLS/CPR


Questions and Answers
  • 1. 

    American Heart updates the Advanced Cardiac Life Support guidelines every?

    • A.

      Year

    • B.

      Six months

    • C.

      Two years

    • D.

      Five years

    • E.

      Ten years

    Correct Answer
    D. Five years
    Explanation
    The AHA revises the ACLS guidelines every 5 years to incorporate new research on resuscitation science.

    Rate this question:

  • 2. 

    In the intrathoracic pressure pump theory on how chest compressions work coronary blood flow occurs during?

    • A.

      Diastole- relaxation/recoil phase

    • B.

      Systole- compression phase

    • C.

      Both

    Correct Answer
    A. Diastole- relaxation/recoil phase
    Explanation
    Coronary blood flow only occurs during diastole in the intrathoracic pressure pump theory as opposed to both systole and diastole in the cardiac compression pump theory of CPR.

    Rate this question:

  • 3. 

    The appropriate rate for chest compressions is?

    • A.

      80/min

    • B.

      80-100/min

    • C.

      99/min

    • D.

      >100/min

    • E.

      120/min

    Correct Answer
    D. >100/min
    Explanation
    The goal is to do greater than 100 compressions per minute but allow for complete chest recoil between compressions.

    Rate this question:

  • 4. 

    The best way to monitor for the effectiveness of CPR is to?

    • A.

      Check femoral pulse during CPR

    • B.

      Monitor the pulse oximeter

    • C.

      Monitor continuous exhaled CO2

    • D.

      Stop CPR and check carotid pulse

    Correct Answer
    C. Monitor continuous exhaled CO2
    Explanation
    Continuous exhaled CO2 provides the best marker for CPR effectiveness. Palpating the pulse is often inadequate and difficult during compressions therefore you should rely on CO2 instead.

    Rate this question:

  • 5. 

    The appropriate ventilation rate for an arresting patient is?

    • A.

      6 breaths per minute

    • B.

      8 breaths per minute

    • C.

      12 breaths per minute

    • D.

      14 breaths per minute

    • E.

      20 breaths per minute

    • F.

      None of the Above

    Correct Answer
    B. 8 breaths per minute
    Explanation
    The goal is to not over or under ventilate an arresting patient. Eight breaths per minute should provide adequate ventilation but result in over ventilation.
