Question

20. The nurse is preparing to administer Vancomycin \( 350 \mathrm{mg} \) IV to the patient. The pharmacy has sent a \( 750 \mathrm{mg} / \mathrm{vial} \) of Vancomycin powder for reconstitution. The

Answer 1

To prepare the Vancomycin IV solution, the nurse needs to use approximately 0.467 mL of the Vancomycin powder for reconstitution.

Step-by-step explanation:

To determine the amount of Vancomycin powder needed, we need to calculate the amount of powder required to make a concentration of 350 mg in the final volume of the solution. To do this, we can use the formula:

Amount of powder (mg) = Desired concentration (mg/mL) × Final volume (mL)

Substituting the given values into the formula, we have:

Amount of powder (mg) = 350 mg/mL × Final volume (mL)

Since the pharmacy has sent a 750 mg/vial of Vancomycin powder, we need to calculate the volume of the vial that will give us the desired concentration.

Volume of vial (mL) = Amount of powder (mg) / Concentration of powder (mg/vial)

Substituting the given values, we have:

Volume of vial (mL) = 350 mg / 750 mg/vial = 0.467 mL

Therefore, the nurse will need to use approximately 0.467 mL of the Vancomycin powder for reconstitution.
