A client weighing 198 lbs requires praziquantel at a dose of 20 mg/kg. How many 600 mg tablets should the nurse administer per dose?

• A. 1 tablet
• B. 2 tablets
• C. 3 tablets
• D. 4 tablets

Answer: (C)

To determine the correct number of 600 mg tablets to administer, we first need to calculate the required dose of praziquantel based on the client's weight and the specified dose per kilogram. The client weighs 198 lbs, which we convert to kilograms for dosing because medication doses are typically calculated in mg/kg. There are approximately 2.2 pounds in a kilogram, so: 198 lbs ÷ 2.2 = 90 kg (approximately). Next, we multiply the weight in kilograms by the required dosage of praziquantel: 90 kg × 20 mg/kg = 1800 mg. Now, to find out how many 600 mg tablets are needed to achieve the total dose of 1800 mg, we divide the total required dose by the strength of each tablet: 1800 mg ÷ 600 mg/tablet = 3 tablets. This calculation shows that the patient requires three 600 mg tablets to meet the prescribed dose of 1800 mg of praziquantel. Hence, the answer is three tablets.
