A nurse is preparing to administer cefotaxime 100 mg/kg/day IM divided in equal doses every 6 hr to a school-age child who weighs 50 lb. Available is cefotaxime injection 300 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.9"]
To calculate the dosage of cefotaxime, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 50 lb, which is approximately 22.7 kg (50 / 2.2). The prescribed dose is 100 mg/kg/day, so the total daily dose is 2,270 mg (100 mg/kg * 22.7 kg). This total daily dose should be divided into equal doses administered every 6 hours, which means 4 doses per day. Therefore, each dose will be 567.5 mg (2,270 mg / 4). With the medication available at a concentration of 300 mg/mL, divide the single dose by the concentration to find the volume per dose: 567.5 mg / 300 mg/mL = 1.89 mL. Rounded to the nearest tenth, the nurse should administer 1.9 mL per dose.

Correct Answer is ["400"]
Explanation
To calculate the infusion rate in mL/hr, you can use the formula: (Total Volume in mL / Time in hours) x 60. For an infusion of 100 mL over 15 minutes, you would first convert the time to hours, which is 15 minutes divided by 60, equaling 0.25 hours. Then, you divide the total volume by the time in hours: 100 mL / 0.25 hours equals 400. Finally, multiply by 60 to convert to an hourly rate: 400 x 60 equals 24,000 mL/hr. However, this number needs to be rounded to the nearest whole number, without a trailing zero. Therefore, the IV pump should be set to deliver 400 mL/hr.
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.
