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.)

Calculation: Convert the client's weight from pounds (lb) to kilograms (kg). Weight in kg = 154 lb / 2.2 lb/kg = 70 kg. Calculate the desired dose in milligrams (mg). Desired dose (mg) = 1 mg/kg × 70 kg = 70 mg. Available concentration of the medication = 40 mg/mL. Calculate the volume in milliliters (mL) to administer. Volume (mL) = Desired dose (mg) / Available concentration (mg/mL) = 70 mg / 40 mg/mL = 1.75 mL. Round the answer to the nearest tenth. =1.8 mL.
