Question

A client with a gram-positive bacterial skin infection is receiving daptomycin 500 mg IV every 24 hours. The pharmacy delivers a secondary infusion of 0.9% Sodium Chloride with daptomycin 500 mg/100 mL to be infused in 30 minutes. How many mL/hour should the nurse program the infusion pump? (Enter the numerical value only.)

A) 100 mL/hour
B) 120 mL/hour
C) 80 mL/hour
D) 60 mL/hour

Answer 1

To deliver
`100 mL` of the infusion in
`30 minutes`, the infusion rate should be set at
`200 mL/hour`. None of the provided options (A, B, C, D) are correct, indicating a potential mistake in the question or answer choices.

Step-by-step explanation:

The question involves calculating the infusion rate for a medication. The nurse needs to program the infusion pump to deliver the medication over a specific period. Given that the pharmacy delivers a secondary infusion of
`0.9%` Sodium Chloride with daptomycin
`500 mg/100 mL` to be infused in
`30 minutes` we can calculate the infusion rate as follows:

To calculate the infusion rate in mL/hour for a total volume of
`100 mL` to be infused over
`30 minutes` use the formula:

Infusion rate (mL/hour) = (Total volume in mL / Infusion time in hours)

Since
`30 minutes` is equal to
`0.5 hours` (
`30 minutes / 60 minutes per hour` ) the infusion rate is:

Infusion rate =
`100 mL / 0.5 hours = 200 mL/hour`

Therefore, the nurse should program the infusion pump to deliver

`200 mL/hour`.

However, based on the options provided, none of them are correct and there may have been a mistake in the question or the options. The closest option is B)
`120 mL/hour`, but it is still not the precise calculation.
