question: 4 of 25
time elapsed: 00:26:44
a nurse is preparing to administer cefazolin 500 mg by intermittent iv bolus every 8 hr. available is cefazolin injection 500 mg in dextrose 5% in water (d,w) 100 ml to infuse over 30 min. the nurse should set the iv pump to deliver how many ml/hr? (round the answer to the nearest whole number. use a leading zero if it applies. do not use a trailing zero.)
ml/hr

Explanation:

Step1: Convert infusion time to hours

The infusion time is 30 minutes. Since 1 hour = 60 minutes, then \(t=\frac{30}{60}=0.5\) hours.

Step2: Use the formula for infusion rate

The formula for the infusion rate (mL/hr) is \(Rate=\frac{Volume (mL)}{Time (hr)}\). Here, the volume \(V = 100\) mL and the time \(t=0.5\) hours. So, \(Rate=\frac{100}{0.5}\).

Answer:

200
