Hesi Medical Dosage Calculation ( 53 Questions)
The healthcare provider prescribes cefazolin 800 mg IM every six hours. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, For IM use add 2.5 mL sterile water for injection to provide a total volume of 3.0 mL". After reconstitution, the solution contains how many mg/mL? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The vial contains 1 gram of cefazolin, which is equal to 1000 mg.
After adding 2.5 mL of sterile water for injection, the total volume of the solution is 3.0 mL.
To find out how many mg of cefazolin are in each mL of the solution, we need to divide the total amount of cefazolin by the total volume of the solution: 1000 / 3 = 333.3333 mg/mL.
Therefore, after reconstitution, the solution contains about 333 mg/mL of cefazolin (rounded to the nearest whole number).
