Final answer:
To administer the correct dose of 350 mg of Kantrax intramuscularly twice a day when it is supplied as 500mg/2ml, calculate the volume to give as 1.4 ml for each dose.
Step-by-step explanation:
The question involves calculating the correct volume of a medication to administer based on the given dosage strength. To clarify, the concentration of the drug Kantrax is 500mg in every 2ml. The order specifies a dose of 350 mg to be given intramuscularly (IM) twice a day. To determine the correct amount in milliliters (mL) to administer for each dose, we would use the formula:
Volume = (Desired Dose) / (Concentration of Solution)
Substituting the values into the formula, we get:
Volume = (350 mg) / (500 mg / 2 mL) = (350 mg) × (2 mL / 500 mg) = 1.4 mL
Therefore, you will administer 1.4 mL of Kantrax for each dose, which will provide the 350 mg required, twice a day. Remember to use aseptic techniques and the correct syringe for an IM injection.
