An IV has been ordered to run at 4 gtt/min. The IV solution contains 836 mg of an active drug in a 250. mL solution. How many milligrams of active drug will the patient receive per hour if the infusion set is calibrated to deliver 13 gtt/mL?

Question

__________ mg of active drug. Report your answer with 3 SFs. Do NOT enter unit.

Answer 1

I'm not a pharmacist or a health professional but this look logical to me. Check it out. Check my thinking.
The solution is 836 mg/250 mL = 3.34 mg/mL
4 gtt/min x 60 min = 240 gtt/hour.
240 gtt/hr x 1 mL/13gtt = 240/13 = 18.5 mL/hr
18.5 mL/hr x 3.34 mg/mL = ?mg/hr
