To determine how much of a 1 mg/mL medication is required to achieve a dose of 5,000 micrograms, it is essential to convert the micrograms to milligrams for an accurate calculation since the concentration of the medication is given in milligrams.

1 milligram (mg) is equal to 1,000 micrograms (mcg). Therefore, 5,000 micrograms can be converted to milligrams as follows:

5,000 micrograms ÷ 1,000 micrograms/mg = 5 mg.

Given that the concentration of the medication is 1 mg/mL, it means that in every 1 mL of the solution, there is 1 mg of the medication. To find out how many milliliters are needed to obtain 5 mg, you set up the equation based on the concentration:

Since 1 mL contains 1 mg, to get 5 mg, you need:

5 mg ÷ 1 mg/mL = 5 mL.

Thus, to achieve a dose of 5,000 micrograms (which is equal to 5 mg), you would withdraw 5 mL of the solution.

The correct answer aligns with this calculation, confirming that to achieve
