Question 58

Short Answer

A patient arrives in the emergency department with a highly elevated blood pressure of 210/100 mm Hg. A calcium channel blocker and potent vasodilator is ordered. The entry of calcium into the cell causes the cell to contract, therefore a calcium channel blocker blocks the entry of calcium into the cell. This action causes decreased contraction, which in turn causes the vessels to relax and vasodilate, which in turn causes decreased blood pressure. The order reads diltiazem 15 mg IV stat. Diltiazem is supplied in 20 mg/2 mL vials. How many mL's would be administered?
