Dysrhythmia Practice

In third degree AV block,

• some atrial beats are conducted to the ventricles

• the is no conduction between the atria and ventricles

• there is delayed conduction between the SA and AV node

• all beats are conducted form the SA node to the AV node

The nurse is reading the cardiac monitor and notes that the patient's heart rhythm is extremely irregular and that there are no discernible P waves with quivering at the isoelectric line. The ventricular rate is 70 beats per minute, and the patient is hemodynamically stable. The nurse realizes that the patient's rhythm is

• atrial tachycardia

• accelerated junctional rhythm

• atrial fibrillation

• atrial flutter

You are caring for a patient in ventricular fibrillation. The code team has just defibrillated the patient and given epinephrine. CPR is resumed for 2 minutes. What is the next action to take?

• Administer Epinephrine

• Defibrillate

• Administer Atropine

• Rhythm & Pulse Check

After intubating a patient, the nurse would administer manual ventilations with what oxygen device and what breath/compression guideline?

• 30:2

  compressions to respirations

• 1 breath every 5-6 seconds

• 15L O2 (100%) through Bag Valve Mask

• 15L O2 (100%) through Ambu Bag to Tube

What are some examples of differential diagnoses that cause cardiopulmonary arrest?
