Question

2. Order: amikacin 0.4 g IVPB q8h Supply: 2 ml vial labeled 250 mg/mk Package directions: dilute in 100ml of D5W and run over 39 minutes Available: Macrodrip tubing 10 gtt/ml How many ml of amikacin should be added to the IV? What are the drops per minute?

Answer 1

0.4 g = 400 mg

So 400 mg of amikacin has to be administered.

250 mg in 1 ml

400 mg in = 1/250 * 400 = 1.6 ml

So 1.6 mk of amikacin should be administered to the IV.

It is to be diluted in 100 ml of D5W and then run over 39 minutes.

So total volume of the solution = 100+1.6 = 101.6 ml

Rate = 101.6/39 = 2.6 ml/min

10 gtt=1 ml

2.6 ml = 2.6 * 10 = 26 gtt

So drops per minute = 26
