3 of 10 questions The nurse needs to convert milliliters to ounces. Which conversion factor is correct? \( \frac{10 \mathrm{oz}}{10 \mathrm{~mL}} \) \( \frac{10 \mathrm{~mL}}{15 \mathrm{~mL}} \) \( \frac{30 \mathrm{~mL}}{10 \mathrm{~mL}} \) 1 oz

To convert milliliters to ounces using a conversion factor, you need a fraction that has “oz” in the numerator and “mL” in the denominator. The standard conversion is approximately:   1 oz ≈ 30 mL Thus, the proper conversion factor is:   (1 oz)/(30 mL) This factor is used to convert a value in mL into oz. For example, if you have 60 mL, you would calculate:   60 mL × (1 oz)/(30 mL) = 2 oz Looking at the options provided: • 10 oz/10 mL → This simplifies to 1 oz per 1 mL, which is off the mark. • 10 mL/15 mL → This is a ratio of volumes without any conversion to oz. • 30 mL/10 mL → This simplifies to a unitless factor of 3. • 1 oz → Not expressed as a conversion factor. None of the options exactly shows (1 oz)/(30 mL). Therefore, the correct conversion factor which you need is:   (1 oz)/(30 mL) This is the factor that would be used for converting milliliters to ounces.
