A nurse is preparing to administer methylphenidate 10 mg PO. Available is methylphenidate oral solution 5 mg/tsp. 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.)

Answer and Explanation

The Correct Answer is ["10"]

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 ["1.5"]

Explanation

To calculate the dosage of cephalexin for the toddler, first convert the weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The toddler weighs 26 lb, which is approximately 11.82 kg (26 / 2.2 = 11.82). Next, calculate the daily dose in milligrams using the prescribed dose of 25 mg/kg/day: 11.82 kg * 25 mg/kg/day = 295.5 mg/day. Since the medication is to be divided into equal doses every 6 hours, there will be four doses per day. Therefore, the dose per administration is 295.5 mg/day divided by 4, which equals 73.875 mg/dose. Now, using the concentration of the cephalexin suspension (250 mg/5 mL), calculate the volume of suspension needed per dose: 73.875 mg * (5 mL / 250 mg) = 1.4775 mL. Rounded to the nearest tenth, the nurse should administer 1.5 mL per dose.

Correct Answer is ["3"]

Explanation

To determine the number of capsules the nurse should administer, divide the prescribed dose of pancrelipase by the amount available per capsule. The calculation is as follows: 12,600 units prescribed divided by 4,200 units per capsule equals exactly 3 capsules. Therefore, the nurse should administer 3 capsules of pancrelipase with each meal.
