Question

a nurse is preparing to administer ceftriaxone 2 g by intermittent iv bolus every 24 hr. available is ceftriaxone injection 2 g in dextrose 5% in water (d₅w) 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.)

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 flow rate

The formula for flow rate (in mL/hr) is \(Flow\ rate=\frac{Volume\ (mL)}{Time\ (hr)}\). The volume \(V = 100\) mL and time \(t=0.5\) hr. So, \(Flow\ rate=\frac{100}{0.5}\).
