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.)

Answer and Explanation

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 ["0.6"]

Explanation

To calculate the volume of furosemide to administer, you would use the formula: Volume = Dose / Concentration. Here, the dose required is 6 mg, and the concentration available is 10 mg/mL. Dividing the required dose by the concentration gives: 6 mg / 10 mg/mL = 0.6 mL. Therefore, the nurse should administer 0.6 mL of furosemide.

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.
