Question

scenario
mrs. turners original orders called for ceftriaxone 1g to be administered intravenously daily. the solution has been diluted to a concentration of 1 g/50 ml to be administered over 30 minutes. twenty minutes into the first infusion, mrs. turner reports an adverse reaction to the antibiotic and the infusion is stopped.
question
how many milliliters of concentration were administered before the infusion was stopped?
round your answer to the nearest whole number.

Explanation:

Step1: Determine the infusion rate

The total volume is 50 mL to be infused over 30 minutes. So the rate is $\frac{50\ mL}{30\ min}$.

Step2: Calculate the volume infused in 20 minutes

Multiply the rate by the time (20 minutes): $\frac{50\ mL}{30\ min} \times 20\ min = \frac{1000}{30}\ mL \approx 33.33\ mL$. Rounding to the nearest whole number gives 33 mL.

Answer:

33
