A nurse is preparing to administer clindamycin 10 mg/kg IM to a school-age child who weighs 77 lb. Available is clindamycin injection 150 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.3"]
Step-by-step calculation:
The child's weight is 77 lb.
The medication dosage is 10 mg/kg.
The available medication concentration is 150 mg/mL.
Calculating the total dose in mg:
Convert the child's weight to kg: 77 lb ÷ 2.2 lb/kg = 35 kg
Calculate the total dose: 35 kg × 10 mg/kg = 350 mg
Calculating the volume to administer:
Use the concentration of the medication: 350 mg ÷ 150 mg/mL = 2.33 mL
Rounding the answer:
2.33 rounds to 2.3 mL

Correct Answer is ["400"]
Explanation
Step by step calculation:
The nurse needs to administer 100 mL of sodium chloride.
The infusion time is 15 minutes.
Calculating the flow rate in mL/hr:
Convert the infusion time to hours: 15 minutes ÷ 60 minutes/hour = 0.25 hours
Divide the total volume by the infusion time: 100 mL ÷ 0.25 hours = 400 mL/hour
Correct Answer is ["0.5"]
Explanation
Convert the child's weight from pounds to kilograms:
55 lb÷2.2=25 kg.
Calculate the total daily dose in mg:
0.3 mg/kg/day×25 kg=7.5 mg/day.
Determine the dose per administration:
The medication is to be given every 8 hours, which equals 3 doses per day.
7.5 mg/day÷3=2.5 mg/dose.
Calculate the number of tablets per dose:
Each tablet contains 5 mg.
2.5 mg÷5 mg/tablet=0.5 tablets.
Round to the nearest tenth:
0.5 tablets
