Question

a patient brings in a prescription for 75 ml of liquid medication. which of the following bottle sizes should the pharmacy technician select to fill this prescription?
2 fl oz
3 fl oz
6 fl oz
8 fl oz

Explanation:

Step1: Recall the conversion factor

We know that \( 1 \text{ fluid ounce (fl oz)} \approx 29.57 \text{ milliliters (mL)} \).

Step2: Convert each option to mL

• For \( 2 \text{ fl oz} \): \( 2 \times 29.57 = 59.14 \text{ mL} \) (less than 75 mL, so not enough)
• For \( 3 \text{ fl oz} \): \( 3 \times 29.57 = 88.71 \text{ mL} \) (more than 75 mL, sufficient)
• For \( 6 \text{ fl oz} \): \( 6 \times 29.57 = 177.42 \text{ mL} \) (more than needed, but 3 fl oz is closer)
• For \( 8 \text{ fl oz} \): \( 8 \times 29.57 = 236.56 \text{ mL} \) (more than needed)

Answer:

3 fl oz
