1. Is not a candidate for an ICD.
2. Will have fewer side effects.
3. Has a supraventricular dysrhythmia.
4. Will respond quicker.
Correct Answer: 3
Rationale 1: ICDs are used as nonpharmacological interventions for treatment of dysrhythmias.
Rationale 2: Side effects will vary, including headache, constipation, hypotension, and bradycardia.
Rationale 3: Only a limited number of calcium channel blockers have been approved for dysrhythmias, and they are only effective against supraventricular dysrhythmias.
Rationale 4: The response time would be quick with any pharmacological treatment.
