A nurse is preparing to administer metronidazole 7.5 mg/kg PO to a client who weighs 146.7 lb. Available is metronidazole 500 mg tablets. How many tablets 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.)

First, let's convert the client's weight from pounds (lb) to kilograms (kg) since the dosage is prescribed in mg/kg. We know that 1 kg is equal to 2.2 lb. Therefore: Client's weight in kg = 146.7 lb / 2.2 lb/kg = 66.6 kg (rounded to two decimal places) Now, we can calculate the total metronidazole dosage for the client using the prescribed dosage of 7.5 mg/kg: Total dosage (mg) = Client's weight (kg) × Dosage (mg/kg) = 66.6 kg × 7.5 mg/kg = 500.25 mg (rounded to two decimal places) Since the medication is available in 500 mg tablets, we can find the number of tablets needed by dividing the total dosage by the tablet strength: Number of tablets = Total dosage (mg) / Tablet strength (mg/tablet) = 500.25 mg / 500 mg/tablet = 1.0005 (rounded to five decimal places) Since we need to round the answer to the nearest whole number, and 1.0005 is closer to 1 than 2, the nurse should administer: 1 tablet of metronidazole.
