2. Your patient with chest pain is started on Nitroglycerin. The drip is going at 3 mL/hr. There is 50 mg of NTG in 250 mL of NS. The patient weighs 100 lbs. What is the dosage in mcg/min?
3. You are giving an amiodarone bolus dose. There is 150 mg of amiodarone in 50 mL of NS. You are ordered to give the dose over 10 minutes. What is the rate in mL/hr?
4. You have given an amiodarone bolus dose. You then start the drip at 1 mg/min. There is 450 mg of amiodarone in 250 mL. The patient weighs 93 kg. How fast is the rate of the drip in mL/hr?
5. You are hanging a bag of Merrem. You are ordered to give 1 mg. There is 1 mg in 100 mL. It is ordered to be given over 1 hr. The patient weighs 100 kg. At what rate will you set the IV pump?
Answers: 1. mL/hr = 500 mL/4mg x 1 mg/1000 mcg x 3 mcg/min x 60 min/hr = 90,000/4,000 = 22.5 mL/hr
2. mcg/min= 1000 mcg/mg x 50 mg/250 mL x 3 mL/hr x 1 hr/60 min = 150,000/15,000 = 10 mcg/min
3. mL/hr = 50 mL/10 min x 60 min/hr = 3,000/10 = 300 mL/hr
4. mL/hr = 250 mL/450 mg x 1 mg/min x 60 min/hr = 15,000/450 = 33.3 mL/hr
