A nurse is preparing to administer lactated Ringer's 150 mL IV to infuse over 30 min. The nurse should set the IV pump 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 ["300"]
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.

Correct Answer is ["0.65"]
Explanation
To calculate the dosage of prochlorperazine that the nurse should administer, we first convert the child's weight from pounds to kilograms, knowing that 1 kilogram is approximately 2.2 pounds. The child weighs 55 pounds, which is equivalent to 55 / 2.2 = 25 kilograms (rounded to the nearest whole number for simplicity). Next, we multiply the child's weight in kilograms by the dosage prescribed, which is 0.13 mg/kg. So, 25 kg * 0.13 mg/kg = 3.25 mg. Finally, since the available medication is 5 mg/mL, we divide the total milligrams needed by the concentration, resulting in 3.25 mg / 5 mg/mL = 0.65 mL. Therefore, the nurse should administer 0.65 mL, rounded to the nearest hundredth.
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.
