The physician ordered tegopen oral solution 50 mg/kg in equally divided doses at 6-hour intervals for a child who weighs 23 pounds

I'm not sure what the question is, but if it has anything to do with how much the child would be getting you can break it down

1kg=2.2lbs

23/2.2=10.45

50x10.45=522.5

Therefore this patient would be getting 522.5mg total.

This patient should be getting 130.625mg every 6 hours.

the gravitational force on an object increase as the mass of an object also, im not going to report you, but this question should be under the science category, not health
