Week 10 Sherpath

Week 10 Sherpath Ventricular Dysrhymias

QuestionAnswer
A patient is diagnosed with ventricular fibrillation. Upon review of the patient history, the nurse expects which medical history from the patient? Myocardial ischemia
Which pathological occurrence explains why this electrocardiogram (ECG) strip is concerning? Increased excitability of myocardial cells
How does the nurse correctly explain the pathophysiology behind an apneic patient with asystole? “Depolarization of the ventricl - es does not occur.”
The nurse is caring for a patient whose recent lab results show higher than therapeutic levels of digitalis. The patient has normal vital signs, denies chest pain, and has no physical abnormalities. The nurse notes an idioventricular rhythm on the ECG tra Continue to monitor the patient
A patient is in sinus rhythm with multifocal PVCs. The patient’s heart rate is 90 bpm with 2+ radial pulses and SpO2 of 85%. Which treatment should be most appropriate for this patient? Start O2 at 2 L/minutes by nasal cannula.
A nurse sees an asystolic rhythm on a patient’s heart monitor. What should the nurse do next? Determine level of consciousness.
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.
Which action is priority for the nurse caring for a patient with this electrocardiogram (ECG) tracing? Palpate the patient’s carotid pulse.
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.
