The nurse is caring for a patient with premature ventricular contractions (PVCs). What should the nurse keep in mind about this heart rhythm?
 
  1. PVCs are insignificant in people with no history of heart disease.
  2. PVCs typically have no pattern.
  3. The frequency of PVCs is not associated with specific events.
  4. Their incidence and significance has no relevance to the patient having had a myocardial infarction.

Question 2

A patient received an implantable cardioverter-defibrillator (ICD). The nurse includes what instruction during discharge teaching for this patient?
 
  1. If a family member is in direct contact with you when the ICD discharges, he or she may experience a shock or tingling sensation.
  2. You can activate the ICD whenever you feel a change in your heart rhythm.
  3. The batteries of the ICD won't need to be replaced if the ICD never shocks the heart.
  4. There should be no discomfort if the ICD discharges, and you probably won't notice it.

Answer to Question 1

Correct Answer: 1
PVCs often have no significance in people without history of heart disease. PVCs may be isolated or occur in specific patterns. They may be triggered by anxiety or stress; tobacco, alcohol or caffeine use; hypoxia, acidosis, and electrolyte imbalances; sympathomimetic drugs; and coronary heart disease. They may be associated with an increased risk for lethal dysrhythmias and their incidence and significance is greatest after myocardial infarction.

Answer to Question 2

Correct Answer: 1
Family members may receive a shock or tingling sensation when in direct contact with an individual when their ICD discharges. The ICD is programmed to automatically activate when detecting a potentially lethal cardiac rhythm and cannot be activated by the patient. Batteries must be surgically replaced every five years or following manufacturer's instructions. Some patients experience significant discomfort with ICD discharge.
