Directions: Calculate the IV medication and infusion rates.Use a calculator for safe dose range calculations,multiplication,and long division as desired.Verify results using DE-style equations where requested.If the order is unsafe,do not proceed with the math.Label answers.
Diltiazem hydrochloride IV maintenance drip infusion has been ordered for a patient diagnosed with atrial flutter,who was treated on admission with a bolus IV dose to lower the ventricular pulse rate.
Order: Titrate the diltiazem HC1 at 5-15 mg per hr to maintain a ventricular pulse rate
90 beats per minute (bpm).Increase by increments of 5 mg per hr
Available: diltiazem hydrochloride 100 mg per 100 mL NS
