I am assuming this is a question for school - please don't rely on my interpretation if you are asking this question in order to administer this drug. I agree this information is confusing. I am looking at Davis's Drug Guide (not sure which edition) on my Ipod, and I think where it says (Neonates full term and/or > 1 wk) it means specifically full term neonates, including full term neonates greater than one week old (the section above gives doses for children 1 month - 5 years). I think where it says (Neonates premature and/or </= 1 wk) it means premature neonates including premature neonates less than 1 week old. So it seems to me that your Full term, 9lb, 1 day old, would fall in to the first category (Neonates full term and/or > 1 wk).
I am not sure that I am right, but this is my interpretation.
