Chapter 26 : Management of Patients With Dysrhythmias and Conduction Problems Questions
Question 1 of 5
A patient has returned to the cardiac care unit after having a permanent pacemaker implantation. For which potential complication should the nurse most closely assess this patient?
Correct Answer: B
Rationale: Bleeding, hematomas, local infections, perforation of the myocardium, and tachycardia are complications of pacemaker implantations. The nurse should monitor for chest pain and bradycardia, but bleeding is a more common immediate complication. Malignant hyperthermia is unlikely because it is a response to anesthesia administration.
Question 2 of 5
A patient the nurse is caring for has a permanent pacemaker implanted with the identification code beginning with VVI. What does this indicate?
Correct Answer: A
Rationale: The identification of VVI indicates ventricular paced, ventricular sensed, inhibited.
Question 3 of 5
The nurse is caring for an adult patient who has gone into ventricular fibrillation. When assisting with defibrillating the patient, what must the nurse do?
Correct Answer: A
Rationale: When defibrillating an adult patient, the nurse should maintain good contact between the paddles and the patients skin to prevent arcing, apply an appropriate conducting agent (not water) between the skin and the paddles, and ensure the defibrillator is in the nonsync mode. Clear should be called three times before discharging the paddles.
Question 4 of 5
A patient who is a candidate for an implantable cardioverter defibrillator (ICD) asks the nurse about the purpose of this device. What would be the nurses best response?
Correct Answer: A
Rationale: The ICD is a device that detects and terminates life-threatening episodes of ventricular tachycardia and ventricular fibrillation. It does not treat atrial fibrillation, MI, or bradycardia.
Question 5 of 5
A nurse is providing health education to a patient scheduled for cryoablation therapy. The nurse should describe what aspect of this treatment?
Correct Answer: D
Rationale: Cryoablation therapy involves using a cooled probe to create a small scar on the endocardium to eliminate the source of the dysrhythmias. Endocardium resection involves peeling away a specified area of the endocardium. Electrical ablation involves using shocks to eliminate the area causing the dysrhythmias. Radio frequency ablation uses high-frequency sound waves to destroy the area causing the dysrhythmias.
