A patient's prescription instructs the administration of one ounce of solution per dose. How many milliliters should be measured for each dose?

1. 5 mL

2. 10 mL

3. 30 mL

4. 65 mL

The correct answer is: 30 mL

To determine how many milliliters correspond to one ounce of solution, it's essential to know the conversion between ounces and milliliters. One ounce is equivalent to approximately 29.57 milliliters. For practical purposes in a pharmacy setting, this is often rounded to 30 milliliters when calculating dosages. Thus, when a prescription indicates one ounce per dose, the correct measurement of solution to administer is 30 milliliters. This understanding of the conversion factors is crucial for accurately dispensing medications and ensuring patient safety. The other options do not reflect the correct conversion from ounces to milliliters, as they either underestimate or overestimate the amount needed for one ounce.
