A nurse is preparing to administer gentamicin 1 mg/kg IM to a client who weighs 154 lb. Available is gentamicin solution 40 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Here's the breakdown: Convert client weight to kilograms (kg): Client weight (kg) = Client weight (lb) / 2.2 lb/kg Client weight (kg) = 154 lb / 2.2 lb/kg Client weight (kg) ≈ 70 kg (rounded to nearest whole number) Calculate desired gentamicin dose in milligrams (mg): Desired dose (mg) = Client weight (kg) x Dose per kg Desired dose (mg) = 70 kg x 1 mg/kg Desired dose (mg) = 70 mg Determine the volume of gentamicin solution to administer: Concentration of available solution: 40 mg/mL Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL) Volume to administer (mL) = 70 mg / (40 mg/mL) Volume to administer (mL) = 1.75 mL (round to nearest tenth) Therefore, the nurse should administer 1.8 mL of the gentamicin solution.
