Dysrhythmias & EKG Interpretation NCLEX Practice | Quiz #1: 20 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:

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?

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:

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?

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?

A client is having frequent premature ventricular contractions. A nurse would place a priority on the assessment of which of the following items?

A client has developed atrial fibrillation, which has a ventricular rate of 150 beats per minute. A nurse assesses the client for:

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:

A client with rapid rate atrial fibrillation asks a nurse why the physician is going to perform carotid massage. The nurse responds that this procedure may stimulate the:

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:

While caring for a client who has sustained an MI, the nurse notes eight PVCs in one minute on the cardiac monitor. The client is receiving an IV infusion of D5W and oxygen at 2 L/minute. The nurse’s first course of action should be to:

The adaptations of a client with complete heart block would most likely include:

A client with a bundle branch block is on a cardiac monitor. The nurse should expect to observe:

When ventricular fibrillation occurs in a CCU, the first person reaching the client should:

What criteria should the nurse use to determine normal sinus rhythm for a client on a cardiac monitor? Select all that apply.

When auscultating the apical pulse of a client who has atrial fibrillation, the nurse would expect to hear a rhythm that is characterized by:

Atherosclerosis impedes coronary blood flow by which of the following mechanisms?

A paradoxical pulse occurs in a client who had a coronary artery bypass graft (CABG) surgery two (2) days ago. Which of the following surgical complications should the nurse suspect?

After cardiac surgery, a client’s blood pressure measures 126/80. The nurse determines that the mean arterial pressure (MAP) is which of the following?

A woman with severe mitral stenosis and mitral regurgitation has a pulmonary artery catheter inserted. The physician orders pulmonary artery pressure monitoring, including pulmonary capillary wedge pressures. The purpose of this is to help assess the:
