Ventricular Dysrhythmias

QuestionAnswer
For which reasons may the nurse confuse ventricular fibrillation for asystole? -Patients are unresponsive in ventricular fibrillation and asystole. - Patients are usually apneic with ventricular fibrillation and asystole. - The irregularly shaped waves of ventricular fibrillation look similar to occasional P waves in asystole.
Why should the patient with a history of myocardial infarction (MI) be monitored closely when premature ventricular contractions (PVCs) are seen on the electrocardiogram (ECG) strip? PVCs may develop into ventricular tachycardia.
Why is the heart rate undetermined for a patient in ventricular fibrillation (VF)? P-to-P intervals and QRS complexes are not measurable.
A patient in ventricular fibrillation (VF) is receiving CPR. What is the priority intervention? Prepare to defibrillate.
The nurse assesses the electrocardiogram (ECG) strip shown here and notes the patient has a palpable peripheral pulse. Which action should the nurse take first? Apply 100% oxygen via non-rebreather.
Which action is priority for the nurse caring for a patient with this electrocardiogram (ECG) tracing? Palpate the patient’s carotid pulse.
