Final answer:
The infusion rate for Vancomycin 500mg IV diluted in 250 mL of D5W and infused over 90 minutes is 166.7 mL/h.
Step-by-step explanation:
To calculate the infusion rate in mL/h, we need to find the number of mL being infused per minute and then convert it to mL/h. First, we need to find the number of mL being infused per minute:
Vancomycin 500mg is ordered to be diluted in 250mL of D5W and infused over 90 minutes:
500mg/250mL = 2mg/mL
Next, we'll convert minutes to hours:
90 minutes ÷ 60 minutes/hour = 1.5 hours
Finally, we'll calculate the infusion rate:
250mL ÷ 1.5 hours = 166.7 mL/h
