Final answer:
To convert 4 liquid ounces to mL, multiply by the conversion factor of 29.5735. This is crucial for accurate measurement in healthcare and culinary contexts.
Step-by-step explanation:
The nurse aid should multiply 4 by 29.5735 to convert four liquid ounces to milliliters (mL), since one liquid ounce is equivalent to approximately 29.5735 mL. To convert 4 liquid ounces to mL, multiply by 29.5735, which is the conversion factor from ounces to milliliters. The conversion between liquid ounces and milliliters is commonly needed in medical and culinary settings. Understanding this conversion is crucial for ensuring accurate measurements for medications, recipes, and scientific experiments.
To perform this conversion, you need to know the conversion factor between these two units of volume. The United States customary system defines one liquid ounce to equal approximately 29.5735 milliliters. Therefore, to convert liquid ounces to milliliters, the number of ounces should be multiplied by this conversion factor. This is a simple multiplication problem once the factor is known. For the case of converting 4 liquid ounces to milliliters, you would calculate 4 ounces × 29.5735 mL/ounce. By multiplying these values together, you get your answer in milliliters. If you were converting the other way round, from milliliters to ounces, you would divide by the conversion factor instead of multiplying.
It's important for a nurse aid or anyone in a position that requires precise measurements of liquid to be familiar with these conversions to ensure accuracy in dosing and administration of fluids. This ensures efficacy and safety in medical treatments and accuracy in various other applications.
