A nurse is preparing to administer gentamicin 5 mg/kg via intermittent IV bolus to a client who weighs 210 lb. The amount available is gentamicin 10 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) ________ mL

Step 1 is to convert the client's weight from pounds (lb) to kilograms (kg) Conversion factor: 1 kg = 2.2 lbs Weight in kg = 210 ÷ 2.2 210 ÷ 2.2 = 95.4545... kg Step 2 is to calculate the total dose in milligrams (mg) Total mg Dose = Weight in kg × Dosage (mg/kg) Total mg Dose = 95.4545... × 5 95.4545... × 5 = 477.2727... mg Step 3 is to calculate the volume to administer in milliliters (mL) Volume = (Ordered Dose ÷ Available Dose) × Available Volume Volume = (477.2727... ÷ 10) × 1 477.2727... ÷ 10 = 47.7272... 47.7272... × 1 = 47.7272... Step 4 is to round to the nearest whole number 47.7272... ≈ 48 Answer: 48
