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 to kilograms. Weight (kg) = 154 lb / 2.2 lb/kg = 70 kg Calculate the prescribed dose in milligrams. Prescribed dose (mg) = 1 mg/kg × 70 kg = 70 mg Available concentration of the gentamicin solution = 40 mg/mL Calculate the volume 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
