Practice Question

A nurse is preparing to administer liquid ibuprofen to a school-age child. The prescription reads 200 mg every 8 hr. The amount available is 100 mg/5 mL. How many mL of ibuprofen should the nurse administer over a 24-hr period? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer Choices:

Correct Answer:

30

Rationale:

✨ Given: 1 dose every 8 hours

🤎 Calculation:

24 hours ÷ 8 hours/dose = 3 doses per day

✨ Given: 200 mg per dose

🤎 Calculation:

200 mg/dose × 3 dose s= 600 mg/day

✨ Given: 100 mg per 5 mL

🤎 Set up proportion:

100mg ÷ 5mL= 600mg ÷ X

✨ Cross-multiply and solve for X:

100X = 3000

X= 3000÷ 100

✍ = 30 mL
