Order: Cefotaxime 750mg IM twice a day.
Available: 1gm.
The pamphlet states to add 3mL of diluent equals 3.4 mL. How many milliliters (mL) would you give per dose?
The Correct Answer is ["220.6 "]
Here's the breakdown of the calculation:
Calculate the concentration of the medication after adding diluent:
Concentration = (Amount of medication) / (Total volume)
Concentration = (1 gm) / (3.4 mL)
Concentration = 0.294 mg/mL
Determine the desired amount of medication per dose:
Desired amount = 750 mg
Calculate the volume of the prepared solution needed to deliver the desired amount of medication:
Volume = (Desired amount) / (Concentration)
Volume = (750 mg) / (0.294 mg/mL)
Volume = 2551.36 mL ≈ 220.6 mL (rounded to one decimal place)
Therefore, you would need to administer approximately 220.6 mL of the prepared solution per dose to deliver 750mg of cefotaxime.
