CPR 2 exam questions


Cardio Pulmonary Resesitation


Unresponsive, no breathing or no normal breathing (only gasping) or no pulse palpated in 10 seconds

CPR Sequence

Compressions, Airway, Breathing

Compressions Rate

30 compressions/ 2 breaths. At least 100 per minute

Compressions Depth

At least two inches deep (5cm)

No Ventilations

If rescuer is untrained or trained and not proficient: Compressions only

CPR sequence

Pt. unresponsive, Call 911, Check for Pulse for 10 seconds, no pulse: start 30 compressions + two breaths cycle, AED/defibulator arrives: check for Shockable rhythm, give one shock, resume CPR immediately for 2 minutes and continue shocking and CPR

High quality CPR

Rate at least 100/min., compression depth 2 inches, allow complete chest recoil after each compression, minimize chest compressions, avoid excessive ventilation

Unresponsive with definite pulse

Call 911. No compressions. Give 1 breath every 5-6 seconds. Recheck pulse every 2 minutes.

Should be planned around uninterrupted periods of CPR

Interventions such as airway insertion, rhythm checks, and drug administration

one shock strategy

may improve outcomes by reducing interruptions in chest compressions

end tidal carbon dioxide device and esophageal detector devices

are indicated for the primary confirmation of correct tracheal tube placement

After advanced airway is inserted

Continue rescue breaths for CPR at about one breath every 6 seconds without pausing CPR compressions

IV large bore catheter

administer fluids if you suspect hypovolemia, then epinephrine, vasopressin or dopamine, as ordered.

Immediately following defibrillation

Perform CPR for 2 minutes then administer drugs

H and T mnemonic

used to determine a differential diagnosis: H&T's. hypoxia, hypovolemia, hydrogen ion (acidosis), hypo or hyperkalemia, hypo or hypercalemia. tablets, tamponade, tension pneumothorax, thormbosis (pulmonary and coronary) and trauma.

VF and pulseless ventricular tachycardia

one shock, then CPR, then shock, then epinephrine or vasopressin), then shock and start antiarrhythmic (amiodarone, lidocaine, magnesium)

Asystole and pulseless electrical activity PEA

vasopressin before epinephrine 40 unit, IV, one time only

Asystole or a slow PEA under 60 bpm (bradycardia)


Symptomatic bradycardia

transcutaneous pacing if patient has second degree type 2 or 3rd degree heart block.

tachycardia with pulses

If stable, EKG to determine the QRS complex is narrow or wide and if the rhythm is regular or irregular. if unstable: immediate synchronized cardioversion followed by drug therapy

Team based BLS/CPR for adults

Chest compressions, airway, breathing, defibrillation all done simultaneously in a in-hospital situation.
