Question

A nurse is preparing a medication and calculates the dosage as 0.893 mL. Rounding this amount to the nearest hundredth, the nurse should administer how many mL?

1) 0.89 mL
2) 0.90 mL
3) 0.88 mL
4) 0.87 mL

Answer 1

The medication dosage of 0.893 mL, rounded to the nearest hundredth, is 0.89 mL.

Step-by-step explanation:

When rounding the medication dosage of 0.893 mL to the nearest hundredth, one must look at the third decimal place to decide how to round the second decimal place. In this case, the third decimal place is 3, which means that you do not increase the second decimal place. Therefore, the correctly rounded dosage to the nearest hundredth is 0.89 mL.The nurse should administer 0.89 mL. When rounding to the nearest hundredth, we look at the digit in the thousandth place (3 in this case). If the digit is 5 or greater, we round up. If the digit is less than 5, we round down. In this case, the digit is 3, so we round down to 0.89 mL.
