  2. These drugs are only prescribed for prophylaxis if you have a family history of dysrhythmias.
  3. Research studies have found that the use of antidysrhythmic medications for prophylaxis can actually increase patient mortality.
  4. Antidysrhythmics have the ability not only to correct dysrhythmias but also to worsen or even create new dysrhythmias.
  5. These drugs cannot be prescribed for prophylaxis since you have a history of diabetes.

Answer to Question 1

3, 4

Rationale 1:You should speak with your physician about receiving a prescription for prophylaxis is incorrect because prophylaxis use of antidysrhythmics can cause dysrhythmias to occur.
Rationale 2:These drugs are only prescribed for prophylaxis if you have a family history of dysrhythmias is incorrect because prophylaxis use of these drugs is based on the patient symptoms and not family history.
Rationale 3: Research studies have found that the use of antidysrhythmic medications for prophylaxis can actually increase patient mortality. This is because there is a narrow margin between a therapeutic effect and a toxic effect with drugs that affect cardiac rhythm. They have the ability not only to correctdysrhythmias but also to worsen or even create new dysrhythmias.
Rationale 4: Research studies have found that the use of antidysrhythmic medications for prophylaxis can actually increase patient mortality. This is because there is a narrow margin between a therapeutic effect and a toxic effect with drugs that affect cardiac rhythm. They have the ability not only to correct dysrhythmias but also to worsen or even create new dysrhythmias.
Rationale 5:These drugs cannot be prescribed for prophylaxis since you have a history of diabetes is incorrect because prophylaxis use of the drugs is not used in the treatment of diabetes.

Global Rationale: Research studies have found that the use of antidysrhythmic medications for prophylaxis can actually increase patient mortality. This is because there is a narrow margin between a therapeutic effect and a toxic effect with drugs that affect cardiac rhythm. They have the ability not only to correctdysrhythmias but also to worsen or even create new dysrhythmias.

Answer to Question 2

1

Rationale 1: Amiodarone (Cordarone) is a potassium channel blocker.
Rationale 2:Acebutolol (Sectral)is incorrect because it is a beta-adrenergic blocker.
Rationale 3:Lidocaine (Xylocaine) is incorrect because it is a sodium channel blocker.
Rationale 4:Mexiletine (Mexitil) is incorrect because it is a sodium channel blocker.

Global Rationale: Amiodarone (Cordarone) is a potassium channel blocker. Lidocaine (Xylocaine)and mexiletine (Mexitil)are sodium channel blockers.Acebutolol (Sectral) is a beta-adrenergic blocker.
