The physician has ordered a nonpharmacologic therapy for a client diagnosed with bradycardia. The nurse anticipates what to be ordered for this client?
 
  1. External defibrillation
  2. Catheter ablation
  3. Calcium channel blockers
  4. Increased exercise

Question 2

Most medications used to treat dysrhythmias block ion channels. Which ion is not blocked when treating dysrhythmia?
 
  1. Magnesium
  2. Sodium
  3. Calcium
  4. Potassium

Answer to Question 1

2

Rationale 1:External defibrillation is used for a ventricular fibrillation or tachycardia, often in the presence of advanced cardiac life support.
Rationale 2:Catheter ablation is successful as a nonpharmacological therapy.
Rationale 3:Calcium channel blockers are medications to treat dysrhythmias.
Rationale 4: Increased exercise will not correct bradycardia.

Global Rationale: Research has demonstrated that catheter ablation and implantable cardioverter defibrillators (ICDs) are more successful in managing certain types of dysrhythmias than the use of medications.

Answer to Question 2

1

Rationale 1: Magnesium channels are not blocked by antidysrhythmic medications.
Rationale 2: Blocking potassium, sodium, or calcium ion channels is the primary pharmacologic strategy used to prevent or terminate dysrhythmias.
Rationale 3: Blocking potassium, sodium, or calcium ion channels is the primary pharmacologic strategy used to prevent or terminate dysrhythmias.
Rationale 4: Blocking potassium, sodium, or calcium ion channels is the primary pharmacologic strategy used to prevent or terminate dysrhythmias.

Global Rationale: Magnesium channels are not blocked by antidysrhythmic medications. Blocking potassium, sodium, or calcium ion channels is the primary pharmacologic strategy used to prevent or terminate dysrhythmias.
