When using a calcium channel blocker, what action is appropriate if the patient becomes hypotensive?

• A. Continue medication and monitor
• B. Hold the dose and contact physician
• C. Increase the dose
• D. Add a diuretic immediately

Answer: (B)

When a patient on a calcium channel blocker becomes hypotensive, the priority is to protect perfusion by stopping the drug and obtaining further orders from the physician. Calcium channel blockers lower blood pressure by dilating arteries and reducing vascular resistance, so if the patient’s BP drops too much, continuing or increasing the dose can worsen hypotension and threaten organ perfusion. Holding the next dose gives the clinician a chance to reassess, determine whether the drug should be resumed at a lower dose or discontinued, and address other contributing factors. While waiting for guidance, monitor vital signs, ensure safety (prevent falls), and document the event. Adding a diuretic would further lower BP and is not appropriate in this situation.
