A client taking diltiazem for hypertension has come to the clinic for a follow-up appointment. The nurse will assess the client for which adverse effects?

A. Chest pain and pale skin: Chest pain and pale skin are not common adverse effects of diltiazem. These symptoms may indicate other conditions, such as a cardiac event, but are not typical side effects of this calcium channel blocker. B. Shortness of breath and wheezing: Shortness of breath and wheezing are more commonly associated with respiratory issues or allergies rather than diltiazem. While diltiazem can cause mild respiratory side effects, wheezing is not a common one. C. Peripheral edema and bradycardia: Peripheral edema and bradycardia are common side effects of diltiazem, a calcium channel blocker. It can cause fluid retention, leading to swelling in the lower extremities, and slow the heart rate, which may result in bradycardia. D. Tachycardia and anxiety: Tachycardia and anxiety are not typical adverse effects of diltiazem. In fact, diltiazem often slows the heart rate, so tachycardia would not be expected. Anxiety is not a known side effect of this medication.
