A nurse is preparing to administer cefoxitin 400 mg by intermittent IV bolus over 1 hr to a school-age child. Available is cefoxitin 400 mg in 50 mL dextrose 5% in water. The nurse should ensure the IV pump is set to deliver how many mL/hr? (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 ["50"]

To calculate the IV pump setting, you would use the formula: Volume (mL) over Time (hr) = Rate (mL/hr). In this case, the total volume of the cefoxitin solution is 50 mL, and it needs to be administered over 1 hour. Therefore, the nurse should set the IV pump to deliver 50 mL/hr. When rounding to the nearest whole number, the rate remains 50 mL/hr.

Correct Answer is ["3.9"]

Explanation

To calculate the dosage of prednisolone syrup for the toddler, first convert the weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The toddler weighs 26 pounds, which is approximately 11.82 kilograms (26 / 2.2). The prescribed dose is 2 mg/kg/day, so the total daily dose is 23.64 mg (11.82 kg * 2 mg). This total daily dose should be divided into two equal doses to be given every 12 hours, resulting in 11.82 mg per dose. With the prednisolone syrup concentration of 15 mg/5 mL, use the formula: (desired dose * volume of one dose) / concentration of the drug to find the volume of syrup per dose. Therefore, the volume for each dose is (11.82 mg * 5 mL) / 15 mg, which equals 3.94 mL. After rounding to the nearest tenth, the nurse should administer 3.9mL per dose.

Correct Answer is ["1.1"]

Explanation

To calculate the dosage of dimercaprol for the adolescent, first convert the weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The adolescent weighs 79 lb, which is approximately 35.91 kg (79 ÷ 2.2). The prescribed dose is 3 mg/kg, so the total dosage required is 107.73 mg (35.91 kg x 3 mg/kg). With the available dimercaprol injection of 100 mg/mL, the nurse should administer 1.1 mL (107.73 mg ÷ 100 mg/mL), rounding to the nearest tenth. Therefore, the nurse should administer 1.1 mL of dimercaprol injection.
