Science Of ACLS And CPR

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

Check femoral pulse during CPR

Monitor the pulse oximeter

Monitor continuous exhaled CO2

Stop CPR and check carotid pulse

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.

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.

About This Quiz

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

2. American Heart updates the Advanced Cardiac Life Support guidelines every?

Year

Six months

Two years

Five years

Ten years

The AHA revises the ACLS guidelines every 5 years to incorporate new research on resuscitation science.

Explanation

The AHA revises the ACLS guidelines every 5 years to incorporate new research on resuscitation science.

3. The appropriate rate for chest compressions is?

80/min

80-100/min

99/min

>100/min

120/min

The goal is to do greater than 100 compressions per minute but allow for complete chest recoil between compressions.

Explanation

The goal is to do greater than 100 compressions per minute but allow for complete chest recoil between compressions.

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

Diastole- relaxation/recoil phase

Systole- compression phase

Both

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.

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.

5. The appropriate ventilation rate for an arresting patient is?

6 breaths per minute

8 breaths per minute

12 breaths per minute

14 breaths per minute

20 breaths per minute

None of the Above

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.

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.
