A 9-year-old boy with severe influenza symptoms will be treated with ribavirin (Rebetol), an antiviral that is usually taken by adults twice daily in doses of 600 mg PO
After learning that the child's body surface area (BSA) is 1.10, the nurse will anticipate that the child will likely receive how much ribavirin for each dose?
A) 110 mg
B) 380 mg
C) 545 mg
D) 660 mg
B
Feedback:
The prescriber calculates a dose based on a known adult dose by using the following equation: pediatric dose = BSA/1.73 × adult dose. Thus, 1.1 ? 1.73 × 600 = 381.5 mg. This would likely be rounded to 380 mg.
