ECCO Test Study Guide

ECCO Test Study Guide A patient has a transcutaneous pacemaker. Which action should the nurse implement when a pacemaker spike occurs but is not followed by ventricular complex? Assess the heart rate Increase the mA Increase the mV Assess the ECG lead placement - Increase the mA A patient has a transvenous temporary pacemaker in place. Pacemaker spikes are noted on the ECG, but they are not followed by a P wave or QRS complex. Which is initially indicated? Reposition patient on the right side Increase the sensitivity (set mV to a lower number). Check the connections. Decrease the mS (output) - Check the connections. A patient has a epicardial temporary pacemaker in place at a rate of 70 and mA of 6. The patient's rhythm is junctional with a rate of 55. No pacemaker spikes are noted on the ECG. Which is initially indicated. Increase the mV on the sensitivity dial Change the batteries Increase the pacemaker rate Increase the mA (output) - Change the batteries A patient's ICD defibrillates and the nurse assesses the patient's rhythm and vital signs. What should be the nurse's next step? Watch to see whether the ICD terminated the dysrhythmia Place a magnet over the ICD Turn off the ICD, and insert a new battery Change the ICD to standby mode - Watch to see whether the ICD terminated the dysrhythmia A nurse notes bradycardia in a patient admitted with subarachnoid hemorrhage and vomiting. What medications may increase the patient's risk of sudden cardiac death due to long QT syndrome? Anticholinergics or phosphodiesterase inhibitors Acetaminophen or calcium channel blockers ACE inhibitors or anticonvulsants Antibiotics or antidysrhythmics - Antibiotics or antidysrhythmics Which patient is at greatest risk for development of torsades de pointes? A patient with a... QTc of 0.40 with hypercalcemia QTc of 0.52 with hypokalemia QTc of 0.44 with hyperphosphatemia QTc of 0.36 with hyponatremia - QTc of 0.52 with hypokalemia A patient has indication for synchronized cardioversion? A patient with: Ventricular tachycardia with BP 100/60 (73) Supraventricular tachycardia with chest pain Atrial fibrillation with a history of VTE Sinus bradycardia with mental status changes
