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.
