Question

a patient brings in a prescription for 8 fl oz of nystatin (mycostatin). which of the following is this amount in milliliters?
options: 120 ml, 240 ml, 360 ml, 480 ml

Explanation:

Step1: Recall the conversion factor

We know that 1 fluid ounce (fl oz) is approximately equal to 30 milliliters (mL). So the conversion factor is \( 1 \text{ fl oz} = 30 \text{ mL} \).

Step2: Calculate the volume in milliliters

The patient has a prescription for 8 fl oz. To convert this to milliliters, we multiply the number of fluid ounces by the conversion factor. So we have \( 8 \text{ fl oz} \times 30 \text{ mL/fl oz} \).

Calculating that: \( 8\times30 = 240 \text{ mL} \).

Answer:

240 mL (corresponding to the option with 240 mL, assuming the options are like "240 mL" as one of them)
