To determine how many minutes it will take to deliver 800 micrograms of the drug at the specified infusion pump rate, first, we need to calculate the amount of the drug that is delivered per minute.

Given that the drug concentration is 50 micrograms per milliliter and the infusion pump is set to deliver 2 mL per minute, the amount of drug delivered per minute can be calculated as follows:

Amount of drug per minute = Concentration × Infusion rate

= 50 micrograms/mL × 2 mL/min

= 100 micrograms/min.

Next, to find out how many minutes it will take to deliver a total of 800 micrograms, we divide the total amount required by the amount delivered per minute:

Time (minutes) = Total drug needed / Amount delivered per minute

= 800 micrograms / 100 micrograms/min

= 8 minutes.

Thus, it will take 8 minutes to deliver 800 micrograms of the drug at the infusion pump settings provided. This analysis shows the systematic approach to breaking down the problem, leading to the determination that the correct answer is indeed the choice stating 8 minutes.
