A nurse is preparing to administer phenytoin 5 mg/kg/day PO divided in equal doses every 12 hr to a school-age child who weighs 38 lb. Available is phenytoin 50 mg chewable tablets. How many tablets should the nurse administer per dose? (Round the answer to the nearest whole number. Us a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1"]

To calculate the dosage of phenytoin for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 38 lb, which is approximately 17.27 kg (38 lb / 2.2). Next, multiply the child's weight in kilograms by the dosage prescribed: 5 mg/kg/day. For this child, that would be 86.36 mg/day (17.27 kg * 5 mg/kg). Since the dose is divided every 12 hours, the amount per dose would be 43.18 mg (86.36 mg/day divided by 2). With phenytoin 50 mg chewable tablets available, the nurse would administer one tablet per dose.

Correct Answer is ["0.5"]

Explanation

To calculate the total milliliters of triamcinolone to administer, you would use the formula: \[Total Volume = (Ordered Dose) / (Concentration)\]. For an ordered dose of 40 mg and a concentration of 80 mg/mL, the calculation would be 40 mg divided by 80 mg/mL, which equals 0.5 mL. Therefore, the nurse should administer 0.5 mL of triamcinolone.

Correct Answer is ["4.4"]

Explanation

To calculate the dosage of amoxicillin and clavulanate for the infant, we first convert the weight from pounds to kilograms, knowing that 1 pound is approximately 0.453592 kilograms. The infant weighs 16 pounds, which is roughly 7.25748 kilograms. The prescribed dose is 30 mg/kg/day, so for the infant, it would be 30 mg/kg/day * 7.25748 kg = 217.7244 mg/day. Since the medication is to be administered every 12 hours, the daily dose should be divided into two, resulting in 217.7244 mg/day / 2 = 108.8622 mg per dose. With the medication available in a concentration of 125 mg/5 mL, we calculate the volume per dose as (108.8622 mg * 5 mL) / 125 mg = 4.354488 mL per dose. Rounding to the nearest tenth, the nurse should administer 4.4 mL per dose.
