How many milliliters of acetaminophen should be administered if the prescription is for 160 mg and the concentration is 100 mg/mL?

To determine how many milliliters of acetaminophen to administer, you can use the concentration of the solution provided. The concentration states that there are 100 mg of acetaminophen in every milliliter of the solution.

The prescription is for 160 mg of acetaminophen. To find out how many milliliters are needed to achieve this dosage, you can set up a calculation using the concentration:

1. Start with the desired dosage: 160 mg.

2. Divide this by the concentration of the solution: 100 mg/mL.

This calculation looks like this:

[ \text{Volume (mL)} = \frac{\text{Desired Dose (mg)}}{\text{Concentration (mg/mL)}} = \frac{160 \text{ mg}}{100 \text{ mg/mL}} ]

Calculating this gives:

[ \text{Volume (mL)} = 1.6 \text{ mL} ]

This indicates that to obtain the required 160 mg of acetaminophen, 1.6 mL of the solution should be administered. Therefore, the correct answer is that 1.6 mL should be administered.
