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.)
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 ["0.5"]
Explanation
To calculate the dosage of quinine for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 36 pounds, which is approximately 16.36 kilograms (36/2.2). Next, calculate the total daily dose of quinine using the child's weight in kilograms: 25 mg/kg/day * 16.36 kg = 409 mg/day. Since the dose is divided into equal doses every 8 hours, divide the total daily dose by 3 to get the per dose amount: 409 mg/day / 3 doses/day = approximately 136.33 mg/dose. Finally, to find out how many 325 mg tablets the nurse should administer per dose, divide the per dose amount by the strength of the tablet: 136.33 mg/dose / 325 mg/tablet = approximately 0.42. Rounding to the nearest whole number, the nurse should administer half a tablet per dose.
Correct Answer is ["300"]
Explanation
To calculate the infusion rate in mL/hr, you can use the formula: (Total Volume in mL) / (Time in hours) = Rate in mL/hr. For lactated Ringer's 150 mL to be infused over 30 minutes, you would first convert the time to hours, which is 0.5 hours (since 30 minutes is half an hour). Then, divide the total volume by the time: 150 mL / 0.5 hours = 300 mL/hr.
