Calculate the milliliters of the erythromycin dilution that should be added to the D5W?
A physician's medication order calls for 800mg of erythromycin to be added to 100ml of D5W for intravenous infusion over 60 minutes. The source of erythromycin is a 1g vial requiring dilution to 20ml with sterile water for injection before being added to the D5W.
2. Calculate the rate of flow of the infusion in liters per minute?
3. If 1 litre of a parenteral fluid is to be administered over a 12 hours period using an infusion set that delivers 20 drops/ml, what will be the rate of flow in drops per minute?

To calculate the milliliters of the erythromycin dilution that should be added to the D5W, you need to know the concentration of the erythromycin dilution and the desired final concentration of the solution.
Let's say the concentration of the erythromycin dilution is 100 mg/mL and you want to make a final solution with a concentration of 10 mg/mL.
First, calculate the amount of erythromycin needed in the final solution:
10 mg/mL * V1 = 100 mg/mL * V2
V1 = (100 mg/mL * V2) / 10 mg/mL
V1 = 10 * V2
Next, calculate the total volume of the final solution:
V1 + V2 = Total volume
10 * V2 + V2 = Total volume
11 * V2 = Total volume
Now, substitute the total volume into the equation to find the volume of the erythromycin dilution needed:
V1 = 10 * V2
V1 = 10 * (Total volume / 11)
If the total volume of the final solution is 1000 mL (1 L), then:
V1 = 10 * (1000 mL / 11)
V1 = 10 * 90.91
V1 = 909.1 mL
Therefore, you would need to add 909.1 mL of the erythromycin dilution to the D5W to achieve a final concentration of 10 mg/mL.

The information provided does not specify the concentration of the erythromycin dilution or the desired final concentration in the D5W, so I cannot calculate the milliliters of erythromycin dilution that should be added.
