Unlikely. As long as it contains available doses and you can easily access the entries, you'll be fine.
I don't if and for how long you have been on the wards, but I would also recommend finding a good website (e.g. micromedix) to find this information on as well. There may be many instances (as happened with me) when you may be separated from your book (or pda) and your resident asks you for that info. Usually though, you will always be near a computer (e.g. in the OR or PACU).
