The patient receives verapamil (Calan). The patient tells the nurse that he is nervous about taking this medicine. What is the best response by the nurse?
1. "This medicine is safe, and most patients do very well with it."
2. "This medicine increases your blood pressure, but we will be monitoring that."
3. "This medicine has many side effects, but you should be okay."
4. "This medicine is a potassium channel blocker and is considered safe."
Correct Answer: 1
Rationale: Calcium channel blockers are safe medications that are well tolerated by most patients. All medications have side effects, but telling the patient that he should be okay is not very reassuring. Verapamil (Calan) is a calcium channel blocker, not a potassium channel blocker. Verapamil (Calan) lowers, not increases, blood pressure and decreases cardiac workload.
