What is the treatment protocol for hypotension after Cardizem administration?

The correct response involves administering 1L of Normal Saline followed by Calcium Chloride. Following the administration of Cardizem (diltiazem), patients can experience hypotension due to the medication's effect on lowering heart rate and blood pressure. In this context, Normal Saline is administered to help restore circulatory volume and improve blood pressure.

Calcium Chloride is a critical component of the treatment protocol. After the use of calcium channel blockers like Cardizem, there can be a relative deficiency of calcium leading to further hypotension or bradycardia. Administering Calcium Chloride can help counteract these effects by providing needed calcium ions to the cardiac muscle and vascular smooth muscle, thereby promoting improved muscular contractility and vascular tone.

Treatments that involve saline alongside other agents might vary in focus, such as addressing the potential needs for fluids and vasopressors, but in this scenario, the specific focus on addressing hypotension following Cardizem points to the combination of Normal Saline and Calcium Chloride as the most appropriate approach.
