Cardiac 4

A patient diagnosed with mitral stenosis exhibits new symptoms of a dysrhythmia. Based on the pathophysiology of this disease process, the nurse would expect the patient to exhibit what heart rhythm?

• Ventricular fibrillation (VF)

• Ventricular tachycardia (VT)

• Atrial fibrillation

• Sinus bradycardia

A patient who has undergone a valve replacement with a mechanical valve prosthesis is due to be discharged home. During discharge teaching, the nurse should discuss the importance of antibiotic prophylaxis prior to which of the following?

• Exposure to immunocompromised individuals

• Future hospital admissions

• Dental procedures

• Live vaccinations

A cardiac surgery patient's new onset of signs and symptoms is suggestive of cardiac tamponade. As a member of the interdisciplinary team, what is the nurse's most appropriate action?

• Prepare to assist with pericardiocentesis

• Reposition the patient into a prone position

• Administer a dose of metoprolol

• Administer a bolus of normal saline

A client is undergoing diagnostic testing for mitral stenosis (MS). Which statement by the client during the nurse's interview is most suggestive of this valvular disorder? Select all that apply.

• "I get chest pain from time to time, but it usually resolves when I rest"

• "Sometimes when I'm resting I can feel my heart skip a beat"

• "Whenever I do any form of exercise, I get terribly short of breath"

• "My feet and ankles have gotten terribly puffy the last few weeks"

• "I had rheumatic fever as a child"

The nurse is caring for a client scheduled for a mechanical valve replacement. Which education will the nurse provide to the client? Select all that apply.

• Use of patient-controlled analgesia

• Long-term anticoagulant therapy

• Steroid therapy

• Use of IV diuretics

• Monitor for bleeding

The nursing educator is presenting a case study of an adult patient who is experiencing abnormal ventricular depolarization. This pathologic change would be most evident in what component of an electrocardiogram (ECG)?

• P wave

• T wave

• QRS complex

• U wave

A nurse is caring for a patient who is exhibiting ventricular tachycardia (VT). Because the patient is pulseless, the nurse should prepare for what intervention?

• Defibrillation

• ECG monitoring

• Implantation of a cardioverter defibrillator

• Angioplasty

During a cardiopulmonary resuscitation (CPR) class, a participant asks about the difference between cardioversion and defibrillation. What would be the instructor's best response?

• 
  "Cardioversion is done on a beating heart, defibrillation is not"

• "The difference is the time of the delivery of the electric current"

• "Defibrillation is synchronized with the electrical activity of the heart, but cardioversion is not"

• "Cardioversion is always attempted before defibrillation because it has fewer risks'

The nurse is caring for a patient who is diagnosed with Raynaud phenomenon. The nurse should plan interventions to address which priority issue?

• Chronic pain

• Ineffective issue perfusion

• Impaired skin integrity

• Risk for falls

A nurse working in a long-term care facility is performing the admission assessment of a newly admitted older adult resident. During inspection of the resident's feet, the nurse notes early evidence of gangrene on one of the great toes. Which condition does the nurse suspect is occurring from this assessment finding?

• Chronic venous insufficiency

• Raynaud phenomenon

• Venous thromboembolism (VTE)

• Peripheral artery disease (PAD)
