A nurse is reviewing a new prescription for haloperidol 0.15 mg/kg/day IM in divided doses every 8 hr PRN for a child who weighs 40 kg. How many mg should the nurse administer with each dose? (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 ["2"]

To calculate the dosage of haloperidol for the child, first determine the total daily dose by multiplying the child's weight by the prescribed amount per kilogram. For a child weighing 40 kg, this would be 0.15 mg/kg/day * 40 kg, which equals 6 mg/day. Since the medication is to be administered in divided doses every 8 hours, divide the total daily dose by the number of doses per day. There are 24 hours in a day, so with doses every 8 hours, that's 3 doses per day. Therefore, 6 mg/day divided by 3 doses per day equals 2 mg per dose.

Correct Answer is ["1.5"]

Explanation

To administer the correct dose of hydrocortisone, which is 7.5 mg, when only 5 mg tablets are available, the nurse would need to give one and a half tablets to achieve the desired dose. 7.5 mg divided by 5 mg per tablet equals 1.5 tablets.

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.
