Dysrhythmias and EKG Interpretation (NCLEX questions)
A nurse is assessing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.16 second, and QRS complexes measure 0.06 second. The overall heart rate is 64 beats per minute. The nurse assesses the
cardiac rhythm as: - Ans Normal Sinus Rhythm
A nurse notices frequent artifacts on the ECG monitor for a client whose leads are connected by cable to a console at the bedside. The nurse examines the client to determine the cause. Which of the following items is unlikely to be responsible for the artifact? - Ans Tightly Secured Cable Connections
A nurse is watching the cardiac monitor and notices that the rhythm suddenly changes.There are no P waves, the QRS complexes are wide, and the ventricular rate is regular but over 100. The nurse determines that the client is experiencing: - Ans Ventricular Tachycardia
A nurse is caring for a client with unstable ventricular tachycardia. The nurse instructs the client to do which of the following, if prescribed, during an episode of ventricular tachycardia? - Ans Inhale deeply and cough forcefully every 1 to 3 seconds.
A nurse is viewing the cardiac monitor in a client's room and notes that the client has just gone into ventricular tachycardia. The client is awake and alert and has good skin color. The nurse would prepare to do which of the following? - Ans Administer amiodarone (Cordarone) Intravenously
A client is having frequent premature ventricular contractions. A nurse would place a priority on the assessment of which of the following items? - Ans Blood pressure and Peripheral Perfusion
A client has developed atrial fibrillation, which has a ventricular rate of 150 beats per
minute. A nurse assesses the client for: - Ans Hypotension and Dizziness
A nurse is watching the cardiac monitor, and a client's rhythm suddenly changes. There are no P waves; instead, there are wavy lines. The QRS complexes measure 0.08 second, but they are irregular, with a rate of 120 beats a minute. The nurse interprets
this rhythm as: - Ans Atrial Fibrillation
A nurse notes that a client with sinus rhythm has a premature ventricular contraction that falls on the T wave of the preceding beat. The client's rhythm suddenly changes to one with no P waves or definable QRS complexes. Instead, there are coarse wavy lines of varying amplitude. The nurse assesses this rhythm to be: - Ans Ventricular Fibrillation
