The nurse is caring for a 45-year-old client with atrial fibrillation who has been receiving diltiazem. Which of the following findings would indicate that the medication has been effective?
Correct answer
D
Rationale
Diltiazem is used in atrial fibrillation to control ventricular rate. A decrease from 158/min to 88/min indicates effective rate control. Blood pressure, chest pain, and stroke prevention are not primary indicators of diltiazem's efficacy in this context.
