- A.
Year
- B.
Six months
- C.
Two years
- D.
Five years

- 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 phaseExplanation
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/minExplanation
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 CO2Explanation
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 minuteExplanation
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.Rate this question:
