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 ["10"]

Explanation

To administer the correct dose of methylphenidate, which is 10 mg, when the available oral solution concentration is 5 mg per teaspoon, the nurse needs to calculate the volume to administer. One teaspoon is equivalent to 5 milliliters (mL). Since the desired dose is 10 mg, and the available solution has a concentration of 5 mg per teaspoon, the nurse would need two teaspoons to make up the 10 mg dose. Therefore, the nurse should administer 10 mL of the methylphenidate oral solution.

Correct Answer is ["1.1"]

Explanation

To calculate the dosage of filgrastim, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 71 pounds, which is approximately 32.27 kilograms (71 lb / 2.2 kg/lb). Next, multiply the child's weight in kilograms by the dosage prescribed, which is 10 mcg/kg. This results in a total dosage of 322.7 mcg (32.27 kg * 10 mcg/kg). Finally, divide the total dosage needed by the concentration of the available medication to find out how many mL to administer. The filgrastim injection available is 300 mcg/mL, so you would administer approximately 1.08 mL (322.7 mcg / 300 mcg/mL), which rounds to 1.1 mL when rounded to the nearest tenth.
