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.

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.
Correct Answer is ["3"]
Explanation
To calculate the dosage of digoxin for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 38 pounds, which is approximately 17.27 kilograms (38 / 2.2 = 17.27). Next, calculate the total daily dose in micrograms by multiplying the child's weight in kilograms by the prescribed dose (17.27 kg * 30 mcg/kg/day = 518.1 mcg/day). Since the dose is divided into three equal parts to be given every 8 hours, divide the total daily dose by 3 (518.1 mcg/day / 3 = 172.7 mcg/dose). Now, convert the dose from micrograms to milligrams (172.7 mcg/dose * 0.001 = 0.1727 mg/dose). Finally, to find out how many milliliters of digoxin elixir to administer per dose, divide the dose in milligrams by the concentration of the elixir (0.1727 mg/dose / 0.05 mg/mL = 3.454 mL/dose). Rounding to the nearest whole number, the nurse should administer 3 mL per dose.
