• Determine the R wave rate.
• Examine the P waves.
• Measure the QRS duration.
• Analyze the ST segment.

A client who is being monitored on a telemetry unit develops sudden-onset narrow QRS tachycardia, rate 185. Which action should the nurse take first?

• Check the client's blood pressure.
• Give the prn beta-adrenergic blocker.
• Prepare for synchronized cardioversion.
• Notify the client's physician.

The physician orders event monitoring for a client who is experiencing dizzy spells to determine whether dysrhythmias are causing the

dizziness. The nurse will teach the client about the need to:

• come to the emergency department for any dizzy spells.
• call the physician when any episodes of dizziness occur.
• initiate recording of the cardiac rhythm when dizziness occurs.
• wear a cardiac monitor for 24 hours continuously to record dizzy spells.

While admitting a 21-year-old college basketball player for an outpatient orthopedic surgery, the nurse notes that the client has a sinus bradycardia, rate 52. Which action should the nurse take next?

• Obtain the transcutaneous pacemaker.
• Notify the client's orthopedic surgeon.
• Administer oxygen at 4 L/min per nasal cannula.
• Document the client's pulse rate on the admission form.

A client develops paroxysmal atrial tachycardia, rate 196, and complains of chest pressure and shortness of breath. All of the following medications are ordered on an as-needed basis for client dysrhythmias. Which one will the nurse administer?

• Atropine (Atropisol)
• Isoproterenol (Isuprel)
• Verapamil (Calan)
• Lidocaine (Xylocaine)

A client admitted to the hospital with dyspnea and palpitations is diagnosed with new-onset atrial fibrillation. In developing the initial plan of

care for the client, the nurse will anticipate the need to:

assist with performing electrical cardioversion.teach the client about the use of anticoagulant medications.instruct the client about the need for lifelong activity restrictions.chemically convert the client with medications such as procainamide.After a client with atrial fibrillation is successfully converted to sinus rhythm with cardioversion, which of the following nursing actions can the nurse delegate to a nursing assistant who is helping with client care?

• Obtain vital signs every 30 minutes.
• Check the client's neurologic status.
• Assess the client's ability to maintain the airway.
• Teach about symptoms of recurrent atrial fibrillation.

When a client is diagnosed with sick sinus syndrome, the nurse will anticipate that the client will require education about

• cardioversion.
• daily oral atropine.
• defibrillation.
• pacemaker insertion.

When the nurse is analyzing an electrocardiogram (ECG) rhythm strip, which information is consistent with a diagnosis of premature junctional contractions (PJCs)?

• The client's T waves are inverted.
• The PR interval is longer than 0.20 second.
• The QRS duration of the extra beats is 0.18 second.
• The extra beats have no P waves before the QRS waves.

A client's PR interval increases from 0.18 second to 0.24 second over a 4-hour period. Which of the following scheduled medications should the nurse withhold until talking with the physician?

• Aspirin (Ecotrin) 325 mg PO
• Furosemide (Lasix) 20 mg PO
• Propranolol (Inderal) 20 mg PO
• Captopril (Capoten) 6.25 mg PO

The nurse has received change-of-shift report about the following four clients. Which one should be assessed first?

• A client with atrial flutter and a ventricular rate of 75 beats per minute
• A client with atrial fibrillation at a ventricular rate of 70 to 90 beats per minute
• A client with premature atrial beats and a ventricular rate of 68 beats per minute
• A client with Mobitz II AV block with a ventricular rate of 66 beats per minute

A client is seen in the clinic with a prolonged QRS duration and a bundle branch block. In order to diagnose the type of bundle branch block,

the nurse anticipates the need for a(n):

• 12-lead electrocardiogram (ECG).
• cardiac magnetic resonance imaging.
• electrophysiology study.
• positron-emitting tomography scan.

The nurse notes that a client who has been admitted with pneumonia has 4 to 5 premature ventricular contractions (PVCs) per minute. Which action should the nurse take?

• Prepare for defibrillation.
• Administer the prn oxygen.
• Notify the physician immediately.
• Give the prn nitroglycerin (Nitrostat).

The nurse notes that the monitor for a client who has just arrived in the emergency department shows a regular rhythm of wide QRSs with no P waves, rate 150. Which action should the nurse take next?

• Determine whether the client is responsive.
• Defibrillate the client at 200 joules.
• Cardiovert the client using 50 joules.
• Administer the prn lidocaine (Xylocaine).
