I'm a nursing student and I have a question regarding Ceftriaxone dosing calculation. I'm not sure if I should start with the 500mg vial reconstituted with 1.0ml of lidocaine or the 1g vial reconstituted with 2.1 ml for lidocaine. Both the 500 mg and 1g vial will give me 350mg/ml after reconstitution but I don't understand how to get the remaining 50 mg needed for the order. I've tried to figure this out with dimensional analysis and I just confuse myself over and over. I'd really appreciate any sage wisdom that can be offered.
Thank you in advance!
