Doctor directives oxicillin 750mg to infuse at 7.5mg/kg/hr for a pt weigh 50kg. How long will the infusion later
Answer:
7.5mg/kg/hr * 50kg = 375 mg/hr
750 mg / (375 mg/hr) = 2 hr
For teh pruposes of this question, which looks resembling someone's homework, the answer is:
7.5 mg/kg/hr times 50 kg = 375 mg/hr
750 mg divided by 375 mg/hr = 2 hours
In real go, we don't order it that route. We just direct 750 mg, and the pharmacy will send it beside infusion instructions. Or, at a push, it might be ordered as 750 mg over 2 hours, or something to that effect.
In the operating room, we usually iv push antibiotics, unless there is a pretext not to (like hypotension with vancomycin)
But that's approach more than you wanted to know.
The "doctor" is correct and you can enlighten she is a doc...check out her spelling.
