Question

a nurse is preparing to administer ceftazidime 1 g by intermittent iv bolus every 12 hr. available is ceftazidime injection 1 g in 0.9% sodium chloride (0.9% nacl) 50 ml to infuse over 15 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.)

Explanation:

Step1: Convert infusion time to hours

Since 1 hour = 60 minutes, then 15 minutes = $\frac{15}{60}=0.25$ hours.

Step2: Use the formula for infusion rate

The formula for infusion rate (mL/hr) is $\text{Infusion Rate}=\frac{\text{Volume (mL)}}{\text{Time (hr)}}$.
We have volume $V = 50$ mL and time $t=0.25$ hr.
So, $\text{Infusion Rate}=\frac{50}{0.25}=200$ mL/hr.

Answer:

200
