Simulated
A nurse is preparing to administer tobramycin 3 mg/kg/day IM in three divided doses to a client who weighs 85 kg. The amount available is Tobramycin 40 mg/mL. How many mL should the nurse administer per dose?(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
2.1 mL
Rationale
Daily dose: 3 mg/kg/day ├ù 85 kg = 255 mg. Per dose: 255 mg ├À 3 = 85 mg. Volume: 85 mg ├À 40 mg/mL = 2.125 mL, rounded to 2.1 mL.
